The Australian lungfish is a primitive and endangered representative of the subclass Dipnoi. The distribution of this species is limited to south‐east Queensland, with some populations considered endemic and others possibly descending from translocations in the late nineteenth century shortly after European discovery. Attempts to resolve the historical distribution of this species have met with conflicting results based on descriptive genetic studies. Understanding if all populations are endemic or some are the result of, or influenced by, translocation events, has implications for conservation management. In this work, we analysed the genetic variation at three types of markers (mtDNA genomes, 11 STRs and 5196 nuclear SNPs) using the approximate Bayesian computation (ABC) algorithm to compare several demographic models. We postulated different contributions of Mary River and Burnett River gene pools into the Brisbane River and North Pine River populations, related to documented translocation events. We ran the analysis for each marker type separately, and we also estimated the posterior probabilities of the models combining the markers. Nuclear SNPs have the highest power to correctly identify the true model among the simulated datasets (where the model was known), but different marker types typically provided similar answers. The most supported demographic model able to explain the real dataset implies that an endemic gene pool is still present in the Brisbane and North Pine Rivers and coexists with the gene pools derived from past documented translocation events. These results support the view that ABC modelling can be useful to reconstruct complex historical translocation events with contemporary implications, and will inform ongoing conservation efforts for the endangered and iconic Australian lungfish.

Climate change involves increases in mean temperature and changes in temperature variability at multiple temporal scales but research rarely considers these temporal scales. The climate variability hypothesis (CVH) provides a conceptual framework for exploring the potential effects of annual scale thermal variability across climatic zones. The CVH predicts ectotherms in temperate regions tolerate a wider range of temperatures than those in tropical regions in response to greater annual variability in temperate regions. However, various other aspects of thermal regimes (e.g. diel variability), organisms' size and taxonomic identity are also hypothesised to influence thermal tolerance. Indeed, high temperatures in the tropics have been proposed as constraining organisms' ability to tolerate a wide range of temperatures, implying that high annual maximum temperatures would be associated with tolerating a narrow range of temperatures. We measured thermal regimes and critical thermal limits (CTmax and CTmin) of freshwater insects in the orders Ephemeroptera (mayflies), Plecoptera (stoneflies) and Trichoptera (caddisflies) along elevation gradients in streams in temperate and tropical regions of eastern Australia and tested the CVH by determining which variables were most correlated with thermal breadth (Tbr = CTmax − CTmin). Consistent with the CVH, Tbr tended to increase with increasing annual temperature range. Tbr also increased with body size and Tbr was generally wider in Plecoptera than in Ephemeroptera or Trichoptera. We also find some support for a related hypothesis, the climate extreme hypothesis (CEH), particularly for predicting upper thermal limits. We found no evidence that higher annual maximum temperature constrained individuals' abilities to tolerate a wide range of temperatures. The support for the CVH we document suggests that temperate organisms may be able to tolerate wider ranges of temperatures than tropical organisms. There is an urgent need to investigate other aspects of thermal regimes, such as diel temperature cycling and minimum temperature. [ABSTRACT FROM AUTHOR]

Introduction: Over 60 % of people who develop breast cancer will receive radiation therapy (RT) as part of their treatment. Side effects of RT may include inflammation, erythema, desquamation and fatigue. Electronic Patient Reported Outcomes Measures (ePROMs) enable patients to report side effects prior to their scheduled post‐RT appointment. This pilot service evaluation aims to explore patients' perceptions regarding the value of the ePROM system, ease of its use and barriers to using the system, after breast irradiation. Methods: From July–November 2021, evaluation surveys were posted to 100 people who had received RT to their breast to explore their experience of using the ePROM. Ethical approval was obtained through Ulster University and the Western Health and Social Care Trust (WHSCT), Northern Ireland. Results: Fifty‐two people responded to the survey, of which 27 respondents indicated that they had accessed the ePROM. Despite few participants experiencing significant side effects, the majority of participants recommended the ePROM indicating that it was an important source of support. Those who experienced significant side effects found the system to be prompt and effective. Barriers to accessing the ePROM included technical issues with the link, concerns about confidentiality and forgetting to access the link. Access to the ePROM increased with higher education levels. Conclusions: This pilot service evaluation demonstrated that ePROMs are valued by patients and can provide rapid real‐time access to support, offering individual care and reassurance. For patients with longer RT schedules (>10 fractions), the introduction of ePROMs during RT was viewed favourably by participants. All patients may benefit from the option of receiving ePROMs post‐RT. [ABSTRACT FROM AUTHOR]

Introduction: Scotland implemented a minimum price per unit of alcohol (MUP) of £0.50 in May 2018 (1 UK unit = 10 mL/8 g ethanol). Some stakeholders expressed concerns about the policy having potential negative consequences for people with alcohol dependence. This study aimed to investigate anticipated impacts of MUP on people presenting to alcohol treatment services in Scotland before policy implementation. Methods: Qualitative interviews were conducted with 21 people with alcohol dependence accessing alcohol treatment services in Scotland between November 2017 and April 2018. Interviews examined respondents' current and anticipated patterns of drinking and spending, effects on their personal life, and their views on potential policy impact. Interview data were thematically analysed using a constant comparison method. Results: Three key themes were identified: (i) strategies used to manage the cost of alcohol and anticipated responses to MUP; (ii) broader effects of MUP; and (iii) awareness and preparedness for MUP. Respondents expected to be impacted by MUP, particularly those on low incomes and those with more severe dependence symptoms. They anticipated using familiar strategies including borrowing and reprioritising spending to keep alcohol affordable. Some respondents anticipated negative consequences. Respondents were sceptical about the short‐term benefits of MUP for current drinkers but felt it might prevent harm for future generations. Respondents had concerns about the capacity of treatment services to meet support needs. Discussion and conclusions: People with alcohol dependence identified immediate concerns alongside potential long‐term benefits of MUP before its introduction. They also had concerns over the preparedness of service providers. [ABSTRACT FROM AUTHOR]

Summary: The complement alternative pathway (AP) is implicated in numerous diseases affecting many organs, ranging from the rare hematological disease paroxysmal nocturnal hemoglobinuria (PNH), to the common blinding disease age‐related macular degeneration (AMD). Critically, the AP amplifies any activating trigger driving a downstream inflammatory response; thus, components of the pathway have become targets for drugs of varying modality. Recent validation from clinical trials using drug modalities such as inhibitory antibodies has paved the path for gene targeting of the AP or downstream effectors. Gene targeting in the complement field currently focuses on supplementation or suppression of complement regulators in AMD and PNH, largely because the eye and liver are highly amenable to drug delivery through local (eye) or systemic (liver) routes. Targeting the liver could facilitate treatment of numerous diseases as this organ generates most of the systemic complement pool. This review explains key concepts of RNA and DNA targeting and discusses assets in clinical development for the treatment of diseases driven by the alternative pathway, including the RNA‐targeting therapeutics ALN‐CC5, ARO‐C3, and IONIS‐FB‐LRX, and the gene therapies GT005 and HMR59. These therapies are but the spearhead of potential drug candidates that might revolutionize the field in coming years. [ABSTRACT FROM AUTHOR]

Global warming is increasing mean temperatures and altering temperature variability at multiple temporal scales. To better understand the consequences of changes in thermal variability for ectotherms it is necessary to consider thermal variation at different time scales (i.e., acute, diel, and annual) and the responses of organisms within and across generations. Thermodynamics constrain acute responses to temperature, but within these constraints and over longer time periods, organisms have the scope to adaptively acclimate or evolve. Yet, hypotheses and predictions about responses to future warming tend not to explicitly consider the temporal scale at which temperature varies. Here, focusing on multicellular ectothermic animals, we argue that consideration of multiple processes and constraints associated with various timescales is necessary to better understand how altered thermal variability because of climate change will affect ectotherms.

This study develops a "comply or explain" index which captures compliance and quality of explanations given for non‐compliance with the corporate governance codes in UK and Germany. In particular, we explain, how compliance and quality of explanations provided in non‐compliance disclosures, and various other internal corporate governance mechanisms, affect the market valuation of firms in the two countries. A dynamic generalised method of moments (GMM) estimator is employed as the research technique for our analysis, which enabled us to control for the potential effects of endogeneity in our models. The findings of our content analysis suggest that firms exhibit significant differences in compliance, board independence and ownership structure in both countries. The "comply or explain" index is positively associated with the market valuation of UK firms suggesting that compliance and quality governance disclosure are value relevant in the UK. Institutional blockholders' ownership is, however, negatively associated with the market value of firms, which raises questions about the monitoring role of institutional shareholders in both countries. We argue that both compliance and explanations given for non‐compliance are equally important, as long as valid reasons and justifications for non‐compliance are provided by the reporting companies. These findings thus imply that the "comply or explain" principle is working well and that UK and German companies could benefit from the flexibility offered by this principle. With respect to the role of board size, board independence, ownership structure, and institutional ownership of firms, this study offers policy implications. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Discussion and Conclusions A minimum unit price (MUP) for alcohol of £0.50 per unit (1 UK unit = 10 mL/8 g alcohol) was introduced in Scotland in May 2018. Few previous studies have examined the impact of alcohol pricing policies on people who are alcohol dependent. This study aimed to evaluate the effect of MUP on people who are alcohol dependent including changes in alcohol consumption and health status, as well as potential unintended consequences.Three waves of cross‐sectional data were collected in Scotland (intervention) and Northern England (control) at 0–6 months pre‐implementation then 3–9 months and 18–22 months post‐implementation. The sample was N = 706 people receiving treatment related to their alcohol use. We collected structured interview data including recent drinking information via a 7‐day timeline‐follow‐back drinking diary. Difference‐in‐difference analyses estimated change in indicators in Scotland compared to England at both post‐implementation timepoints.The proportion of participants consuming alcohol costing on average <£0.50 per unit in Scotland decreased from 60.6% at 0–6 months prior to MUP implementation to 6.3% at 3–9 months post‐implementation (p < 0.0004). There was no significant change in the indicators for alcohol consumption, severity of dependence, health status, other substance use, deprivation level or parenting.The introduction of MUP in Scotland was associated with increases in the prices paid for alcohol by people with dependence and presenting to treatment services. There was no evidence of changes in their alcohol consumption or health status. There was also no evidence of harmful unintended consequences for this population. [ABSTRACT FROM AUTHOR]

Objectives: This study investigated goals identified by people with dementia and their carers to promote the self‐management of symptoms and abilities; measured achievement using goal attainment scaling (GAS); and explored the reflections of Dementia Support Practitioners (DSPs) facilitating it. Methods and design: Within this pragmatic randomised trial, DSPs gave memory aids, training and support to people with mild to moderate dementia and their carers at home. Data were collected across seven NHS Trusts in England and Wales (2016–2018) and abstracted from intervention records and semi‐structured interviews with DSPs delivering the intervention, supplemented by a subset of the trial dataset. Measures were created to permit quantification and descriptive analysis and interview data thematically analysed. A GAS measure for this intervention in this client group was derived. Results: Engagement was high across the 117 participants and 293 goals were identified. These reflected individual circumstances and needs and enabled classification and assessment of their attainment. Seventeen goal types were identified across six domains: self‐care, household tasks, daily occupation, orientation, communication, and well‐being and safety. On average participants achieved nominally significant improvement regarding the specified goals of 1.4 with standard deviation of 0.6. Five interviews suggested that DSPs' experiences of goal setting were also positive. Conclusions: GAS is useful for assessing psychosocial interventions for people with early‐stage dementia. It has a utility in identifying goals, promoting self‐management and providing a personalised outcome measure. There is a strong case for exploring whether these clear benefits translate to other interventions in other populations in other places. [ABSTRACT FROM AUTHOR]

In the trapdoor spider genus Euoplos Rainbow & Pulleine (tribe Euoplini), it was discovered recently that two divergent lineages occur in sympatry in eastern Australia. This challenged the monogeneric classification of the tribe and, in combination with inadequate taxonomic descriptions of some species, precluded comprehensive taxonomic revision. To resolve these issues, we conducted a total‐evidence cladistic analysis on a largely undescribed continental fauna—the first such analysis on a group of Australian Mygalomorphae. We combined multilocus molecular data and/or morphological and behavioural data from all known species from eastern Australia (described and undescribed), plus a subset of Western Australian species, to produce a phylogeny for the tribe. We mapped morphological/behavioural characters onto this to identify clade‐specific diagnostic characters, and applied these data to a generic reclassification of the tribe. We recovered two sympatric lineages in the Euoplini (the "wafer‐door" and "plug‐door/palisade" lineages), and revealed the phylogenetic position of all known eastern Australian species within these. Character mapping revealed morphological and behavioural (burrow architecture) features that allow diagnosis of the lineages and clades within them. We erect a new genus, Cryptoforisgen.n., to represent the wafer‐door lineage, describe the type species, Cryptoforis hughesaesp.n., and transfer two species from Euoplos to Cryptoforis: C. tasmanica (Hickman, 1928) and C. victoriensis (Main, 1995). This study resolves phylogenetic structure within the Euoplini, and characterizes clades within the tribe to facilitate future taxonomic revisions. It also demonstrates that, whereas male morphology is more informative, female morphological characters relating to genitalia and the scopulation/spination of the anterior legs display phylogenetic signal in the Euoplini, highlighting the subtle nature of informative female characters in mygalomorph spiders.

Objective: To explore the complexities, circumstances, and range of services commissioned for people with dementia living at home.Methods: A national survey was used to collect data from English local authorities in 2015. Commissioners of services for older adults were invited to complete a questionnaire. An exploratory cluster analysis of nominal data was conducted using a TwoStep procedure to identify distinct groups.Results: A total of 122 authorities (83%) responded to the request. Four approaches to commissioning were identified, reflecting commissioning practices at the organisational, strategic, and individual service user levels. Commissioning at the service user level was most apparent. Bivariate analysis found that these configurations were not associated with the types of dementia specific services provided but were related to the number available. Authorities delivered a greater range of specialist services when joint commissioning between social care and health partners was undertaken. However, the joint commissioning of services was less observed in services specifically for people with dementia than in generic services for all older people. There was limited evidence that local circumstances (population configuration and deprivation levels) were associated with this approach to commissioning.Conclusions: The significant role of health partners in the delivery of social care services to support older people living with dementia in their own homes is evident. As the population with dementia ages and physical health needs increase, how dementia specific services differ from and complement those services available to all older people warrants further investigation.

A comprehensive knowledge of migratory behaviour is paramount for the effective management and conservation of fishes in coastal drainages. The Australian smelt (Retropinna semoni) is a common fish distributed throughout coastal and inland drainages in south‐eastern Australia. Multiple life history patterns (potamodromy, facultative diadromy, estuarine residence) in the southern regions of its geographic distribution have been reported, and it is possible that some of these differences reflect characteristic behaviours of cryptic species within the group. To elucidate the life history patterns of smelt at the northern extent of their range and to identify any differences in migratory behaviour between two genetically distinct lineages ("SEQ‐N", "SEQ‐S") in this region, the movement patterns of Australian smelt were assessed using otolith chemistry. No evidence of marine residence was found based on otolith Sr:Ca and Ba:Ca transects for either group, suggesting that both are non‐diadromous. Significant differences in multi‐elemental otolith chemistry signatures were found among rivers and between paired sites within some rivers, suggesting no connectivity among drainages and limited dispersal of individuals over large spatial scales within rivers. These findings provide key insights into the migratory patterns of northern Australian smelt populations and, in combination with previous research, suggest that life history variation in the Australian smelt complex may occur primarily at the intra‐population level rather than among genetically distinct lineages. Conservation and management strategies for Australian smelt should take limited dispersal and individual life history variation into consideration in order to protect the components of this important species complex.

Closely related species may have different patterns of distribution and spatial population structure in common landscapes, which can have implications for conservation of the species if they are vulnerable. The Australian mountain galaxias species complex has recently been split into 15 described species, 11 of which are threatened. In this study, we assessed the distribution and landscape genetic structure of two mountain galaxias species (Galaxias olidus and Galaxias oliros) in the Goulburn–Broken catchment (Murray–Darling Basin) in relation to hydrographic descriptors of river terrain, network and hydrology. We also assessed small‐scale population structure in juvenile G. oliros in tributary streams of the Goulburn River (the Granite Creeks).Analyses of distribution revealed that G. olidus mostly occurs in smaller streams at high elevations with steep valley slopes and high stream gradients downstream, whereas G. oliros mostly occurs in larger downstream waterways with higher magnitude and variability of stream flow.Population genetic structure in G. olidus was much greater than for G. oliros, with 17 of the 19 sampled locations resolved as genetically distinct populations for G. olidus, but only a single population revealed for G. oliros. Results for both species did not reflect the expectations of the stream hierarchy model or isolation‐by‐distance model. However, small‐scale spatial population structure in juvenile G. oliros in the Granite Creeks reflected the expectations of both stream hierarchy and isolation‐by‐distance models, suggesting that population structure of juveniles of this species reflects some level of spatial aggregation of closely related individuals that probably diminishes as the population ages.Higher landscape genetic structure in G. olidus was correlated with steeper stream and valley slopes, whereas no population genetic correlations were significant for G. oliros. Genetic diversity in G. olidus was higher in areas of greater hydrological variability, suggesting that populations in hydrologically variable areas function as a metapopulation and have a more diverse gene pool than populations in areas with lower hydrological variability. In contrast, genetic diversity in G. olidus was lower in higher elevation areas with steep valley slopes, suggesting that smaller but more stable populations occur in high elevation streams with high perenniality and low interannual variability of flows.Our results are consistent with other studies that highlight the importance of supporting natural hydrological regimes and natural patterns of hydrological connectivity for conservation of vulnerable freshwater fish.

Objective: Women of childbearing age with new cancer diagnoses have to make rapid decisions about fertility preservation (FP) before starting cancer treatment (CT). The aim of the PreFer study was to explore this FP decision-making process and its impact on patient-reported outcomes (PROMs) and health-related quality of life (HRQoL).Methods: A prospective, mixed-methods design was used (questionnaires, in-depth interviews). Interviews were analysed using thematic analysis. Fifty-eight women with new cancer diagnoses were recruited. Comparisons were made between women who declined FP referral in oncology (Group1) and women who chose referral (Group2). Group 2 was further split into those who had some FP (2A) and those who did not (2B). Questionnaires and PROMs were administered prior to and after the fertility consultation, before the start of CT and 3 months post CT. Interviews were conducted with one participant from Group 2.Results: HRQoL was negatively affected, particularly depression. Women's lack of understanding about the relationship between CT and fertility were evident. Five themes emerged from the interviews as barriers and facilitators to the FP decision-making process.Conclusion: The results indicate that better information and support resources aimed at women to support their decision making are needed, such as patient decision-aids. Women from Group 1 were found to suffer significantly worse depression compared with the general UK population, highlighting the need for psychological support in the FP care-pathway and for research exploring the contributions of depression and hopelessness to the decision-making process.

Objectives: This study investigated staff roles and tasks in Community Mental Health Teams (CMHT) and memory clinics, which are provided within a framework determined by local Clinical Commissioning Groups.Methods: A cross-sectional survey design was used to collect data in England in 2015. Teams were identified by mental health providers (n = 68) and invited to complete a questionnaire.Results: Fifty-one NHS Trusts responded to the request. The response rate varied. Data were obtained for all Clinical Commissioning Groups areas in 3 of the 9 regions in England, but only half in one of them. CMHTs were significantly more likely to have larger staff groups. Compared with memory clinics they were also more likely to have staff that were not professionally qualified. The occupational therapist role showed a strong association with the provision of all services in CMHTs. Both CMHTs and memory clinics provided information and advice about dementia. CMHTs provided more services associated with the support of a person with dementia at home.Conclusion: Variations in the staff mix in CMHTs and memory clinics reflected their different functions. There was limited evidence in both of profession specific interventions relating to the provision of support, information, therapy and education, associated with either diagnosis or long-term support. The potential for a single service to undertake both diagnostic and long-term support and the associated costs and benefits are areas for future research. [ABSTRACT FROM AUTHOR]

Abstract: An important challenge for conservation science is to detect declines in intraspecific diversity so that management action can be guided towards populations or species at risk. The lifespan of Australian lungfish (Neoceratodus forsteri) exceeds 80 years, and human impacts on breeding habitat over the last half century may have impeded recruitment, leaving populations dominated by old postreproductive individuals, potentially resulting in a small and declining breeding population. Here, we conduct a “single‐sample” evaluation of genetic erosion within contemporary populations of the Australian lungfish. Genetic erosion is a temporal decline in intraspecific diversity due to factors such as reduced population size and inbreeding. We examined whether young individuals showed signs of reduced genetic diversity and/or inbreeding using a novel bomb radiocarbon dating method to age lungfish nonlethally, based on 14C ratios of scales. A total of 15,201 single nucleotide polymorphic (SNP) loci were genotyped in 92 individuals ranging in age from 2 to 77 years old. Standardized individual heterozygosity and individual inbreeding coefficients varied widely within and between riverine populations, but neither was associated with age, so perceived problems with recruitment have not translated into genetic erosion that could be considered a proximate threat to lungfish populations. Conservation concern has surrounded Australian lungfish for over a century. However, our results suggest that long‐lived threatened species can maintain stable levels of intraspecific variability when sufficient reproductive opportunities exist over the course of a long lifespan.

Abstract: Many thousands of Mary River turtle eggs were harvested for the pet trade in the 1960s and 1970s before it was recognized as a new species in a unique genus. Pet turtles and their descendants still survive in captive collections. Elusor macrurus is now an endangered species after suffering dramatic population declines along the single Australian river that constitutes its entire range. A conservation genetic assessment was conducted to evaluate population subdivision within the remaining wild population of the Mary River turtle; to compare diversity of the wild population with a captive sample derived from the pet trade; and to establish a baseline estimate of effective population size (Ne) to assist with future monitoring and recovery. Microsatellite analysis indicated panmixia throughout most of the Mary River catchment with the exception of one downstream tributary –Tinana Creek (pop. Specific FST = 0.154). Subdivision between Tinana Creek and Mary River is a feature common to multiple co‐distributed freshwater taxa including the threatened Australian lungfish and Mary River cod. Microsatellite diversity of the wild adult population was low (average HS = 0.554) and not significantly different from that of a sample of captive turtles from the pet trade – indicating genetic diversity may be well represented in captive stocks. Mitochondrial DNA diversity was extremely limited, with only two haplotypes found in the wild and a single shared haplotype in captive turtles. Estimates of Ne applicable to the entire species in the wild were ~136 and ~158 using two independent methods. A reasonable management objective should be retention of Ne levels >100 during recovery of the species. Additional recommendations include that Mary River turtles be listed as Critically Endangered, and that a recovery plan be developed that considers ‘headstarting’ – using captive bred stocks to supplement the wild population.

Artesian springs are particularly sensitive freshwater ecosystems, characterized by specialized flora and fauna which, owing to their isolation, are often endemic. Thus, protection of spring habitats and endemic spring biota is important for biodiversity conservation, particularly because human impacts such as invasive species, habitat destruction, and fragmentation can have such devastating effects., This study investigated the mitochondrial DNA (mtDNA) genetic diversity and structure of two critically endangered (IUCN) freshwater fish species: red-finned blue-eye Scaturiginichthys vermeilipinnis, and Edgbaston goby Chlamydogobius squamigenus, with the aim of assisting management agencies to establish relocated populations that conserve the genetic integrity and evolutionary potential of both species., 2862 bp from multiple mtDNA genes were amplified from 111 red-finned blue-eye individuals (17 from the 1990s and 94 from 2010), and a 660 bp segment of mtDNA cytochrome b was amplified from 111 Edgbaston goby individuals (from 2010). In total, 14 concatenated mtDNA haplotypes were identified in red-finned blue-eye and three cytb haplotypes were identified in Edgbaston goby., Overall assessment of the genetic diversity and structure of the endemic fish fauna from the Edgbaston springs revealed low levels of diversity in both species and a loss of haplotypes in red-finned blue-eye over time. In addition, both species displayed significant genetic structure: at the spring scale for red-finned blue-eye and at the spring group scale for Edgbaston goby. It is concluded that without the appropriate management of relocated populations, such as considering genetic structure and diversity and selecting high quality habitats, these species are at a severe risk of losing evolutionary potential and becoming extinct. This study provides a valuable example for conservation managers of the contribution that population genetic studies can make regarding the adaptive management of endangered species., Copyright © 2016 John Wiley & Sons, Ltd.

Accounting for genetic diversity and evolutionary processes has long been recognised as an important goal in conservation planning. However, because genetic data are often lacking, surrogate approaches are widely used. Few studies have, however, assessed the capacity of surrogate data, such as higher taxonomic levels (e.g. species distributions) to portray intraspecific genetic diversity., Here, we contrast conservation plans based on traditional species distribution data, with those derived from intraspecific genetic data for a smaller subset of species, both using freshwater fish in northern Australia. We modelled the spatial distribution of 46 species and intraspecific genetic diversity within four common species. We then identified priority areas for conservation using both data sets and evaluated the extent to which solutions obtained from species distribution data portrayed genetic diversity., We found that genetic diversity could be adequately represented within priority areas identified using species distribution data, even at low conservation targets and for species with complex genetic structure. However, this was only true when using the entire fish community (i.e. all 46 species). In contrast, a substantial component of the genetic structure would not be represented in conservation priority areas when using a subset of species., Our results have important implications for the use of surrogates for genetic diversity in conservation planning. Sufficient genetic diversity might be represented in conservation priority areas by including a broad range of species with distributions ranging from common to rare elements in the community in the prioritisation analyses. We recommend focusing on improving accuracy of data on species distributions to reduce uncertainties in conservation recommendations derived from commission and omission errors, to avoid misuse of limited conservation funds and potential failure of conservation practice.

Objective: To measure the long-term impact of surgical treatment for vulval cancer upon health-related quality of life and pelvic floor outcomes during the first year of therapy.Methods: Prospective, longitudinal, mixed-methods study. Twenty-three women aged >18 years with a new diagnosis of vulval cancer were recruited. The EORTC QLQ C30, SF-36 and an electronic pelvic floor assessment questionnaire (ePAQ-PF) were administered at baseline (pre-treatment) and 3, 6, 9 and 12 months post-treatment. Mixed effects repeated measures models (all adjusted for age and BMI) were used to investigate changes over time and differences between cancer stage. Qualitative interviews were carried out with 11 of the women and analysed using a thematic approach.Results: Mean age was 59.9 years (SD = 15.3; range = 23.8-86.6 yrs). Mean BMI was 30.0 (SD = 4.5; range = 24.4-38.2). Sixteen women had early (Stage 1 to 2B), and seven women had advanced stage disease (Stage 3 to 4B). Questionnaire scores revealed that physical and social functioning, fatigue, pain and general sex life were significantly worse at 12 months than pre-treatment (p = < 0.05). Qualitative analysis revealed multiple treatment side effects which were perceived as severe and enduring. Women with advanced vulval cancer had significantly worse SF-36 mental health scores at 12 months compared to women with early stage disease (p = 0.037).Conclusions: Surgery for vulval cancer has long-term implications which can be persistent 12 months post-treatment. High rates of morbidity relating to lymphoedema and sexual function re-enforce the need for specialist clinics to support women who suffer these complications. © 2015 The Authors.

Amphidromy, the dispersal of larvae to the estuarine or marine environment with juveniles recolonising fresh waters to complete development, is common on tropical islands. This has led to the suggestion that amphidromy is an adaptation to hydrologically unpredictable environments, allowing recolonisation after local extinction (dispersal-limitation hypothesis). Alternatively, amphidromy may be more common in streams with stronger flow, as high tractive forces flush larvae into the estuarine/marine environment, forcing them to recolonise (passive dispersal hypothesis)., We tested these hypotheses in a continental gobiid fish, the Roman Nose Goby ( Awaous acritosus) that inhabits hydrologically and physically diverse catchments on the east coast of Australia. We measured 87 Sr/86 Sr along transects of the otoliths of 92 adult fish from 12 catchments, identified migratory life histories from these data and correlated the proportion of migratory fish with key environmental variables. This information was augmented with data from mt DNA ( n = 276) and six microsatellite loci ( n = 429) from 19 catchments, to explore gene flow among catchments and to assess whether local adaptation was likely in the face of high or restricted gene flow., Estimates of 87 Sr/86 Sr along transects revealed high variation in life history, with 63% of individuals showing no evidence of marine/estuarine residence. The slope of catchments was the only significant variable associated with the proportion of larvae retained in catchments, with steep catchments having a greater proportion of adults exhibiting a marine/estuarine phase during early life. Total panmixia was detected with mt DNA and six microsatellite loci, suggesting that gene flow is high for this species., These results support the passive dispersal hypothesis. Steep slopes are likely to have higher tractive forces in their flow, leading to a greater proportion of larvae being flushed into the estuary or sea. In addition, high gene flow would inhibit local adaptation, making the dispersal-limitation hypothesis unlikely., This study provides a framework for understanding how local adaptation may be constrained by gene flow across the landscape so that the adaptive or passive mechanism underlying facultative amphidromy can be explored.

Southern smelts ( Retropinna spp.) in coastal rivers of Australia are facultatively diadromous, with populations potentially containing individuals with diadromous or wholly freshwater life histories. The presence of diadromous individuals is expected to reduce genetic structuring between river basins due to larval dispersal via the sea. We use otolith chemistry to distinguish between diadromous and nondiadromous life histories and population genetics to examine interbasin connectivity resulting from diadromy. Otolith strontium isotope (87 Sr:86 Sr) transects identified three main life history patterns: amphidromy, freshwater residency and estuarine/marine residency. Despite the potential for interbasin connectivity via larval mixing in the marine environment, we found unprecedented levels of genetic structure for an amphidromous species. Strong hierarchical structure along putative taxonomic boundaries was detected, along with highly structured populations within groups using microsatellites ( FST = 0.046-0.181), and mt DNA (ΦST = 0.498-0.816). The presence of strong genetic subdivision, despite the fact that many individuals reside in saline water during their early life history, appears incongruous. However, analysis of multielemental signatures in the otolith cores of diadromous fish revealed strong discrimination between river basins, suggesting that diadromous fish spend their early lives within chemically distinct estuaries rather than the more homogenous marine environment, thus avoiding dispersal and maintaining genetic structure.

Objective This study aimed to investigate the factors associated with the delayed discharge of older people from hospital and their length of stay (LOS). Methods Data were collected retrospectively from inpatient records and adult social care services on older patients referred to the latter prior to hospital discharge. Results Data on two related measures-delayed discharge and LOS-were analysed separately within a four-stage sequential framework. Using bivariate analysis, we found that cognitive impairment and dependency were significantly associated with delay. Patients admitted to trauma and orthopaedics specialties were significantly more likely to be delayed on discharge. Respiratory illness was negatively associated with delay. Factors related to care received as an inpatient associated with delayed discharge from hospital were not being in the responsible consultant's bed for part of their stay, two or more moves between specialties and receipt of rehabilitation services. Admission to a care home and receipt of domiciliary care if returning to a private dwelling on discharge were associated with delay. In the multivariate analysis, dependence and cognitive impairment impacted differently on delay and LOS. Hospital variables were the most important predictors of LOS and social care variables in respect of delayed discharge. Conclusion Patient characteristics and especially the organisation of care in hospital and the provision of services on discharge are related to the likelihood of delayed discharge and LOS. Improved services and structures to systematically assess and treat patient needs in hospital, together with the timely provision of services providing post-discharge services tailored to individual circumstances, are required.

This study reports on an investigation into the campus-based experience of university students studying mammalian physiology that was significantly supported with learning technologies. The design of the course enabled the students to interrogate the key ideas that they came across in their lectures and laboratories through online activities which prepared the students for practical classes. Close-ended questionnaires were used to uncover qualitative variation in the population sample, particularly the differences in the concepts of learning technologies and approaches to learning technologies. Qualitative variation in concepts of, and approaches to, learning technologies was found to be significantly associated with variation in academic achievement. The outcomes have important implications for the approaches to teaching of campus-based experiences of learning supported by learning technologies when we seek to support all students to realise their learning outcomes in technology-mediated processes [ABSTRACT FROM AUTHOR]

The research reported in this paper takes up Michael Power's challenge that accounting researchers should pay more attention to the perceptions of auditees and how they respond to audit regimes. The setting of the study is the intense performance assessment regime imposed on local authorities in England from 2002 to 2009, one part of which - the Use of Resources (UoR) assessment - rated the financial management capability and performance of each English local authority. The perceptions of senior local authority finance officers within the Yorkshire and the Humber region are reported, using a written questionnaire and an interview to explore the reasoning behind the chosen responses. The results are more nuanced than suggested by either the official rhetoric justifying the UoR system or by those critics who view such systems as dysfunctional. Respondents portray themselves as intelligent actors, not as passive recipients. Most learned to use the UoR process to drive performance improvement, though there is some ambiguity as to whether the improvements were genuine or solely a product of the scoring system. Though adding to workload, UoR was regarded as one of the external pressures to be managed and its requirements largely represented professional views of best practice. Three of the types of control that characterise 'regulation inside government' (Hood et al., 1999) - oversight, competition and contrived randomness - are seen through the perceptions of the auditees. There is some evidence of the fourth style, mutuality - working through professional networks to help local authorities improve their actual and reported performance. [ABSTRACT FROM AUTHOR]

1. Effective management of aquatic fauna requires knowledge of the ways in which populations in different catchments and sub-catchments are connected. A powerful way to estimate this is using genetic markers, which provide information on the average amount of genetic connectivity among populations over generations. Although many studies of genetic connectivity have appeared in the literature, there are innumerable species that have not been studied. 2. This study explores whether it is possible to make broad generalisations about population connectivity, based on readily available information in the form of species life history and architecture of the aquatic habitat. 3. A number of models have been proposed to explain the pattern of connectivity shown by aquatic species with different life-history characteristics, for example, the stream hierarchy model, Isolation by Distance, the Death Valley Model, the headwater model and panmixia. 4. In this study, we propose a dichotomous key to assign species to different models of potential connectivity. The key is based on a few very simple questions about the life history of the species and the geographical arrangement of study sites. We then assessed the performance of the key with 109 data sets of Australian fish and macroinvertebrates, using genetic data to provide an estimate of realised connectivity. 5. The realised connectivity fitted the proposed potential connectivity model in over 70% of cases, and we suggest this might be a useful initial approach for managers where empirical data are lacking.

Small crustaceans are diverse and abundant in seagrass habitats and provide many ecological services. Further information is needed about their long- and short-term response to habitat fragmentation and loss. Shrimp specimens were sampled from coastal seagrasses: latitudes 9°-27° S (Torres Strait to Moreton Bay, Queensland, Australia) and longitudes 141°-153° E (Weipa to Moreton Bay, Queensland, Australia). The seagrass shrimp Phycomenes zostericola (Caridea: Decapoda) underwent phylogeographic analysis using mitochondrial and nuclear sequence data. Lineage relationships were investigated and two deeply divergent sympatric lineages of P. zostericola were discovered in northern samples. The two lineages display vastly different demographic histories in spite of similar overall phylogeographic patterns. The two lineages appear to be in secondary contact with each other, detailing independent histories of sea level change, long distance colonisation and habitat fragmentation. Their regional structure is evidence that the potential for dispersal is only realised under specific environmental conditions. Nuclear data, used to determine reproductive status between lineages, instead displayed a non-random latitudinal geographic distribution suggesting directional selection, possibly in response to ocean temperatures. The differences between the two deeply divergent lineages highlight the importance of understanding variability among cryptic taxa and their response to habitat change. [ABSTRACT FROM AUTHOR]

Indicators of the public provision of old age social care are routinely recorded in England and have been used for diverse purposes including performance monitoring. Despite long-term policy guidance promoting more homogeneous service provision, large variations can still be observed between local authorities (the providers of state-funded social care). Our aim is to better understand such variations in a small selection of key aggregate indicators. Drawing on multiple data sources and pursuing a two-step strategy, we first assess the explanatory power of a set of structural predictors and then add to the models a set of specific care management 'process' predictors. We find that structural factors beyond the control of local authorities explain a considerable share of the observable variation. The additional explanatory power of care management characteristics is small in comparison. Therefore, our findings suggest that caution must be taken when aggregate indicators of service provision are used for performance monitoring purposes, as a degree of autonomy over outcomes may be implied which in light of the empirical evidence is unrealistic. Past attempts to influence the aggregate pattern of service provision - apparently seeking greater 'territorial justice'- are likely to have had adverse implications for service users and the uniformity of service delivery across England. Questions are raised about the adequate role of central government in a policy environment characterized by longstanding local government responsibility. [ABSTRACT FROM AUTHOR]

Ashelby, C.W., Page, T.J., De Grave, S., Hughes, J.M. & Johnson, M.L. (2012) Regional scale speciation reveals multiple invasions of freshwater in Palaemoninae (Decapoda). - Zoologica Scripta, 41, 293-306. The generic level, systematic relationship in Palaemoninae was inferred from analyses based on the mitochondrial 16S rDNA and nuclear Histone (H3) genes, primarily focussed on the genera Palaemon and Palaemonetes, as previous morphological and molecular studies indicated potential paraphyly in some genera. Palaemonetes, Exopalaemon, Coutierella and certain Palaemon recover as a strongly supported monophyletic clade, but with the exception of Palaemon concinnus, P. pandaliformis and P. gracilis. Within this clade, six major clades are identified with geographic relationships appearing stronger than generic relationships. The data strongly suggest that Palaemon, Palaemonetes, Exopalaemon and Coutierella are synonymous and that the morphological characters currently used to define these genera require re-evaluation. Freshwater species are not closely related to each other, but instead group with geographically close marine species, suggesting multiple invasions of freshwater by physiologically plastic ancestors rather than a single colonisation event with subsequent speciation.

Summary 1. Conservation plans are required to safeguard freshwater biodiversity in the face of increasing threats. Traditionally plans have used surrogates for biodiversity that do not account for the evolutionary process, but genetic data in the form of comparative phylogeography can fulfil this role. 2. Comparative phylogeographic analyses of multiple freshwater fish and decapod crustacean species were carried out with specimens from two model systems, namely the sand dune islands of Fraser and North Stradbroke in eastern Australia. 3. Almost all of the species studied from both islands displayed an intraspecific evolutionary split between sides of the island (east/west on North Stradbroke Island, and north/south on Fraser Island), indicating that each side of each island hosts its own distinct community of populations of freshwater animals. 4. The probable process responsible for both of these divergent communities is different source populations for each side of each island. 5. This study shows that biodiversity will not always follow obvious geography and that significant diversity may exist at small scales within multiple species. These evolutionarily relevant units of biodiversity should be incorporated at the beginning of the conservation and resource management planning process. [ABSTRACT FROM AUTHOR]

Summary 1. The highly variable hydrology of dryland rivers has important implications for population dynamics in these systems. In western Queensland, fluctuations in sub-population size are likely to lead to local bottlenecks and extinctions, increasing the need for connectivity and gene flow to maintain population viability. 2. Using microsatellite markers, we explored evidence for this metapopulation structure in two species of freshwater fish ( Maquaria ambigua and Tandanus tandanus) and one crustacean ( Macrobrachium australiense) in a sub-catchment of the upper Murray-Darling Basin, Australia. 3. Overall, we found very weak genetic structure for all three species. Two species ( M. ambigua and M. australiense) showed some significant genetic structure that did not correlate with geographic distance. However, decomposed pairwise regression analysis revealed evidence for intense genetic drift at the waterhole scale, suggesting that local bottlenecks are driving what little genetic structure does exist for these species. 4. The results identify the local impact of bottlenecks on genetic diversity, but highlight the importance of gene flow in maintaining population viability in these highly variable systems. As the impacts of bottlenecks are likely to be tempered by gene flow, it is suggested that the maintenance of connectivity is of paramount importance in this dryland system. [ABSTRACT FROM AUTHOR]

Although most vertebrates reproduce sexually, a small number of fishes, amphibians and reptiles are known in which reproduction is asexual, i.e. without meiotic recombination. In fishes, these so-called unisexual lineages usually comprise only females and utilize co-occurring males of a related sexual species to reproduce via gynogenesis or hybridogenesis. Here, we examine patterns of microsatellite and mitochondrial DNA (mtDNA) variation in a widespread group of freshwater fishes (carp gudgeons; Hypseleotris spp.) to investigate a long-standing proposal that this group includes unisexual forms. We show that the mtDNA genome of most carp gudgeons in tributaries of the Goulburn River belongs to one of two deeply divided clades (∼10% cyt b divergence) and that nuclear variation divides the same individuals into four distinct groups. Group 1 exhibits the genotypic proportions of a random mating population and has a 1:1 sex ratio. Two other groups are extremely sex-biased (98% male, 96% female), exhibit excess heterozygosity at most loci and share at least one allele per locus with group 1. We propose that these two groups represent 'unisexual' hybridogenetic lineages and that both utilize co-occurring group 1 as sexual host. Interestingly, the fourth distinct group appears to represent hybrid offspring of the two putative hybridogenetic lineages. The propagation of clonal haploid genomes by both males and females and the ability of these clones to unite and form sexually mature diploid hybrid offspring may represent a novel mechanism that contributes to the dynamics of coexistence between hybridogenetic lineages and their sexual hosts.

1. We performed spatial genetic analyses, incorporating landscape genetic methods using microsatellite data and phylogeographic analyses using mtDNA data, to identify the principal factors that determine population heterogeneity of the tropical freshwater fish, Mogurnda mogurnda, in the Daly River, northern Australia. We tested the individual and interactive effects of several environmental variables on spatial genetic patterns, including metrics relating to connectivity (i.e. stream distance, maximum stream gradient and elevation), habitat size (i.e. mean annual discharge) and a categorical variable relating to population history, as determined by mtDNA phylogeographic analyses. The Daly River is geomorphologically and hydrologically complex, and M. mogurnda has life history traits that limit its dispersal potential at river basin scales. Thus, we predicted that variables relating to connectivity would be the most important landscape factors driving population structure of the species. 2. Tree-based phylogeographic analyses indicated four divergent mtDNA lineages within M. mogurnda in the Daly River, although three of the lineages were sympatric in various combinations and did not correspond with microsatellite groups identified by assignment tests. The allopatric mtDNA lineage detected in the uppermost part of the catchment was also identified as being highly differentiated by the microsatellite data, strongly suggesting that it may be a cryptic species. This site was therefore excluded from subsequent landscape genetic analyses. 3. Analyses of Molecular Variance indicated that M. mogurnda has a hierarchical population structure in the Daly River, thus supporting theoretical expectations that hierarchically arranged river habitats in dendritic systems impose hierarchal population structures on lotic species. 4. All landscape genetic analyses rejected stream distance, and supported stream gradient, as the major determinant of spatial genetic variation in M. mogurnda in the Daly River. Support for elevation as a determinant of spatial genetic patterns differed among the landscape genetic methods. Several of the landscape genetic methods also indicate that population history, including secondary contact between divergent and formerly allopatric genetic lineages, has a strong influence on spatial genetic patterns within M. mogurnda in the Daly River. 5. This study demonstrates the need to consider multiple environmental factors, especially factors relating to connectivity, and their interactions in spatial genetic analysis, rather than just geographic distance. Importantly, it demonstrates the need to account for population history and evolutionary divergences in landscape genetic analyses. [ABSTRACT FROM AUTHOR]

1. The freshwater crayfish Cherax dispar (Decapoda: Parastacidae) inhabits coastal regions and islands of South East Queensland, Australia. We hypothesised that populations of C. dispar on different islands would be more genetically divergent from each other than populations from different drainages within the same island or on the mainland. 2. Phylogenetic and phylogeographic analyses were conducted on two mitochondrial genes (cytochrome oxidase subunit I & 16S ribosomal DNA) and one nuclear gene (Internal Transcribed Spacer region 2). Phylogeographic patterns were compared with those for other freshwater organisms in the area. 3. Deep genetic divergences were found within C. dispar, including four highly divergent (up to 20%) clades. The geographic distribution of each of the clades revealed strong latitudinal structuring along the coast rather than structuring among the islands. The high genetic divergence observed among the C. dispar clades was estimated to have pre-dated island formation and may represent ancient river drainage patterns. 4. A restricted distribution was observed for the most divergent clade, which was discovered only on two of the sand islands (North Stradbroke Island and Moreton Island). Furthermore, strong phylogeographic structuring was observed within this clade on North Stradbroke Island, where no haplotypes were shared between samples from opposite sides of the island. This low connectivity within the island supports the idea that C. dispar rarely disperse terrestrially (i.e. across watersheds). [ABSTRACT FROM AUTHOR]

Aim Caridean shrimp are diverse and abundant inhabitants of seagrass beds. Anthropogenic disturbances have already reduced and fragmented seagrass habitat, and the rate of change is likely to increase in the future. It is therefore becoming increasingly important to build a basis of understanding of connectivity among populations of seagrass-associated fauna. Phycomenes zostericola is closely associated with seagrass and makes an ideal study species with which to explore patterns of connectivity and the influence of biogeographic boundaries and historical sea-level changes on seagrass-associated species. We hypothesized that strong currents and the high potential of P. zostericola for dispersal and adult movement would result, for the most part, in panmixia. We also hypothesized that if structure was evident, it would occur close to known biogeographic boundaries in Queensland. Location Phycomenes zostericola is an abundant shrimp species distributed throughout Queensland’s seagrass habitats. Nineteen seagrass sites from the Torres Strait Islands and Queensland coastlines were sampled. Methods Molecular sequence data for a 590 base pair fragment of the mitochondrial gene cytochrome c oxidase subunit I (COI) was analysed for 279 specimens of P. zostericola. Phylogeographic patterns were analysed using nested clade phylogeographic analysis (NCPA); an isolation-by-distance effect was tested using a Mantel test; the effect of biogeographic boundaries was tested using an analysis of molecular variance (AMOVA), and also a spatial analysis of molecular variance (SAMOVA); demographic expansions were tested for using Tajima’s D, Fu’s FS and timing estimated using mismatch analysis; the timing of vicariant events was estimated using coalescent analysis (im program). Results Contrary to our original hypothesis, the strong marine currents are not a connective influence among populations of P. zostericola. Regional genetic structure and an isolation-by-distance effect are enhanced by existing coastal biogeographic boundaries. Population genetic structure and demographic history are intricately linked to the effects of a tumultuous Pleistocene sea-level history on the Queensland continental shelf. Main conclusions Connectivity diminishes among populations of P. zostericola over scales larger than a few hundred kilometres. As seagrass habitats world-wide become increasingly fragmented, low levels of connectivity will result in an isolated future for P. zostericola and other species reliant on seagrass as habitat.

Aim To use molecular data to test for dispersal structuring in the immigration history of an amphidromous community on an island. Location The Caribbean island of Puerto Rico. Methods Mitochondrial DNA sequences were obtained from 11 amphidromous species, including shrimps, fish and a gastropod, sampled from throughout the island. The timing of population expansion ( TE) in each species was calculated using nucleotide variation and molecular clock dating methods. The order of species accumulation was then reconstructed (oldest to most recent estimate for TE), and groups of species with non-overlapping estimates for TE were identified. The temporal span and average immigration rate for each group were calculated and compared with expectations of two previously published models of island immigration [the ‘dispersal-structured model of island recolonization’ ( Whittaker & Jones, Oikos, 1994 , 69, 524–529), which predicts short phases of rapid immigration followed by extended phases with relatively slow immigration rates; and the ‘colonization window hypothesis’ ( Carine, Taxon, 2005 , 54, 895–903), which suggests that opportunities for island colonization are temporally constrained to discrete waves of colonization]. Results The molecular data indicated the immigration history of Puerto Rican amphidromous fauna from the late Pleistocene through the Holocene and identified two groups of species with non-overlapping estimates for TE and one group that overlapped with the other two groups. The temporal span, average immigration rate and lack of discreteness between all three groups indicated a continuum of immigration rather than distinct phases of species arrivals. Main conclusions This study did not support the expectations of the immigration models and suggested that amphidromous species from Puerto Rico comprise a single class of marine-based dispersers. The immigration sequence we report probably reflects a recolonization chronology in this community, in keeping with the notion of species turnover through time. Four areas of future research into the immigration history of amphidromous species on islands are identified, and indicated the possibility that equilibrium processes govern long-term community change in amphidromous biota on islands.

Background Peer support schemes of various types are commonly offered to patients as an adjunct to health and social care services provided by professionals. For patients with chronic illness, peer support interventions have recently become associated with more directive attempts to increase self management and improve healthcare outcomes. There is little qualitative research on patients’ experiences of one-to-one peer support. Purpose To explore kidney patients’ experiences of receiving individual peer support. Setting Two large teaching hospital renal units in South London, with peer support services for patients on the pre-dialysis care pathway. Methods Qualitative telephone interviews with a purposive, maximum variation sample of 20 people who had received peer support. Results The majority of respondents were overwhelmingly positive about their experience of peer support and its benefits. They valued peer support because it had given them access to practical information about kidney disease, based on lived experience, which helped them reach decisions about treatment. Peer supporters offered patients empathy and understanding; confirmation that they were not alone in suffering; positive role models of coping with treatment for kidney disease; and hope for the future. Peer support helped patients adapt to chronic illness by normalizing adherence to demanding treatment regimes and increasing patients’ sense of empowerment and agency. Conclusions A brief meeting with a peer supporter delivered similar perceived benefits to those described by participants in support groups. Possible explanations for this include selection and training of peer supporters; careful matching of patients with peer supporters; and responsiveness to individual user-defined needs for information and psychosocial support.

Context: Large-scale, whole-systems interventions in health care require imaginative approaches to evaluation that go beyond assessing progress against predefined goals and milestones. This project evaluated a major change effort in inner London, funded by a charitable donation of approximately $21 million, which spanned four large health care organizations, covered three services (stroke, kidney, and sexual health), and sought to “modernize” these services with a view to making health care more efficient, effective, and patient centered. Methods: This organizational case study draws on the principles of realist evaluation, a largely qualitative approach that is centrally concerned with testing and refining program theories by exploring the complex and dynamic interaction among context, mechanism, and outcome. This approach used multiple data sources and methods in a pragmatic and reflexive manner to build a picture of the case and follow its fortunes over the three-year study period. The methods included ethnographic observation, semistructured interviews, and scrutiny of documents and other contemporaneous materials. As well as providing ongoing formative feedback to the change teams in specific areas of activity, we undertook a more abstract, interpretive analysis, which explored the context-mechanism-outcome relationship using the guiding question “what works, for whom, under what circumstances?” Findings: In this example of large-scale service transformation, numerous projects and subprojects emerged, fed into one another, and evolved over time. Six broad mechanisms appeared to be driving the efforts of change agents: integrating services across providers, finding and using evidence, involving service users in the modernization effort, supporting self-care, developing the workforce, and extending the range of services. Within each of these mechanisms, different teams chose widely differing approaches and met with differing success. The realist analysis of the fortunes of different subprojects identified aspects of context and mechanism that accounted for observed outcomes (both intended and unintended). Conclusions: This study was one of the first applications of realist evaluation to a large-scale change effort in health care. Even when an ambitious change program shifts from its original goals and meets unforeseen challenges (indeed, precisely because the program morphs and adapts over time), realist evaluation can draw useful lessons about how particular preconditions make particular outcomes more likely, even though it cannot produce predictive guidance or a simple recipe for success. Noting recent calls by others for the greater use of realist evaluation in health care, this article considers some of the challenges and limitations of this method in the light of this experience and suggests that its use will require some fundamental changes in the worldview of some health services researchers.

Background This paper provides an initial evaluation of the impact of the Single Assessment Process (SAP) in England upon practice regarding multidisciplinary assessment. Objectives To investigate changes in recorded health needs of older people and in the number of multidisciplinary assessments undertaken using social care agencies' case files. To examine differences in approaches to the use of multidisciplinary assessment for older people with different health needs. Methods An audit of case files of older people living in the community in receipt of social care in three areas carried out at two time periods before and after implementation of the SAP in 2004. Information extracted from files covered a number of domains including evidence of multidisciplinary assessments, and presence of mental and physical health problems. Results Data from 144 files at Time 1 were compared with 145 files from Time 2. Little evidence emerged that older people at Time 2 were more dependent. However, significantly more multidisciplinary assessments were undertaken following the introduction of the SAP, in particular by occupational therapists and secondary health care teams. Cognitive impairment was a significant predictor of multidisciplinary assessment at both time periods. Conclusions The impact of the introduction of the SAP has been mediated by the influence of other policies in England: intermediate care and integrated health and social care provision. Nevertheless, the data suggest that consideration be given to more effective targeting of multidisciplinary assessments on the grounds of both cost and more accurate identification of those who will benefit from the process.

Background Care management is the formal mechanism for linking people with intellectual disabilities with public services but little is known about these arrangements. This paper present findings from a national survey. Materials and Methods The questionnaire covered aspects of care management arrangements and was specific to services for people with intellectual disabilities. They were sent to all social services departments in England. Results The response rate was 81%. Variations were found in organizational arrangements, the performance of key care management tasks, and the degree of differentiation in approach according to need. Local authorities also differed in arrangements for person centred planning. Conclusions Further review of the relative efficiency and effectiveness of different care management approaches is needed to inform policy development and promote consistency in services for people with intellectual disabilities.

This paper considers the relationship between corporate strategy formulation and taxation. Drawing on prior literature we briefly review the important influence that international taxation has on an array of corporate strategy decisions. We then consider issues in strategy formulation and taxation planning in order to develop an understanding of when and how taxation factors impinge on strategic decision-making. We draw out the apparent paradox between the nature of strategic decision-making and financial decision-making and look for areas of reconciliation. In order to shed light on some of these issues we present findings from the qualitative analysis of a set of personal interviews undertaken with senior tax practitioners in seven UK-based multinational enterprises and then consider quantitative responses from the tax practitioners working in 145 UK firms.

Taxon cycling, i.e. sequential phases of expansions and contractions in species’ distributions associated with ecological or morphological shifts, are postulated to characterize dynamic biogeographic histories in various island faunas. The Caribbean freshwater shrimp assemblage is mostly widespread and sympatric throughout the region, although one species (Atyidae: Atya lanipes) is geographically restricted and ecologically and morphologically differentiated from other Atya species. Using patterns of nucleotide variation at the COI mtDNA gene in five species of freshwater shrimp ( A. lanipes, A. scabra, A. innocuous; Xiphocarididae: Xiphocaris elongata; Palaemonidae: Macrobrachium faustinum) from Puerto Rico, we expected to detect a signature of sequential colonization in these shrimp, consistent with the concept of taxon cycling, and expected that A. lanipes would be at a different taxon stage (i.e. an early stage species) to all other species. We also examined patterns of genetic population structure in each species expected with poor, intermediate and well-developed abilities for among-river dispersal. Population expansions were detected in all species, although the relative timing of the expansions varied among them. Assuming that population expansions followed colonization of Puerto Rico by freshwater shrimp, results bear the hallmarks of sequential colonization and taxon cycling in this fauna. A. lanipes had a star phylogeny, low mean pairwise nucleotide differences and recent (Holocene) estimates for an in situ population expansion in Puerto Rico, and it was inferred as an early stage species in the taxon cycle undergoing a secondary phase of expansion. All other species were inferred as late stage species undergoing regional population expansions, as their mean pairwise nucleotide differences were relatively high and phylogenetic patterns were more complex than A. lanipes. High rates of gene flow without isolation by distance among rivers were detected in all species, although results should be treated cautiously as some populations are unlikely to be in mutation–drift equilibrium. Nested clade analysis produced inconsistent results among species that all have high rates of gene flow and expanding populations. [ABSTRACT FROM AUTHOR]

1. We determined whether two sympatric mitochondrial DNA (mtDNA) lineages of freshwater shrimp (Decapoda: Atyidae: Paratya australiensis) represent biological species and if they had concerted or independent population responses to hydrographic factors in small streams (the Granite Creeks) in southeastern Australia. 2. Allozyme data indicated the presence of two gene pools at sites where the P. australiensis lineages were co-occurring and the gene pools were statistically assigned with high probability to each respective lineage. This indicated that these mtDNA lineages in P. australiensis were reproductively isolated and thus biological species. 3. Populations of both lineages were genetically homogeneous among lowland sites within streams, but were isolated by steep stream gradients among upland sites and for lowland–upland site comparisons. However, the magnitude of differentiation was markedly different between the two lineages. Allozyme diversity also differed between the two lineages, suggesting that they have different effective population sizes. Thus, differences in the magnitude of genetic divergence among populations were probably because of different life-history characteristics, including dispersal ability and population size. 4. Genetic population structure was mostly temporally stable, despite the extreme effects of drought during the first year and substantial stream-flow during the second. However, stable isotope analyses revealed greater local movement in both lineages during the second year, as greater hydrological connectivity provided more opportunities for dispersal. Thus, although lowland populations within streams were genetically homogeneous, stable isotope data indicated that connections may be sporadic and result from accumulated small-scale movements among refugial pools. 5. Both lineages were therefore found to have similar small-scale population responses to the unstable habitats of the Granite Creeks. Results highlight the importance of refugia for the capacity of biota to recover from drought and the need for multiple restored patches to reinstate natural population processes (e.g. resilience, recolonization) in degraded systems.

While many studies have documented the effect that glacial cycles have had on northern hemisphere species, few have attempted to study the associated effect of aridification at low latitudes in the southern hemisphere. We investigated the past effects that cyclic aridification may have had on the population structure and history of a widespread endemic Australian bird species, the Australian magpie ( Gymnorhina tibicen). One thousand one hundred and sixty-six samples from across its native range were analysed for mitochondrial control region sequence variation and variation at six microsatellite loci. Analysis of mitochondrial control region sequence data indicated monophyletic clades that were geographically congruent with an eastern and western region. The contemporary distribution of east and west clades is nonoverlapping but in close proximity. Populations were estimated to have diverged in the Pleistocene around 36 000 years ago. The putative Carpentarian and Nullarbor arid barriers appear to be associated with the divergence between east and west mainland populations. Nested clade analysis indicated a signature of range expansion in the eastern region suggesting movement possibly inland and northward subsequent to the last period of aridity. The island population of Tasmania was of very recent origin, possibly since sea levels rose 16 000 years ago. Given the east-west structure, there was no congruence between morphology and recent history of this species indicating a lack of support for morphological taxa. Overall mitochondrial DNA and microsatellite variation suggest that increasing aridity and Pleistocene refugia played a role in structuring populations of the Australian magpie; however, the dispersal ability and generalist habitat requirements may have facilitated the movement of magpies into an almost contiguous modern distribution across the continent. This study supports the idea that Pleistocene aridification played an important role in structuring intraspecific variation in low latitudinal southern hemisphere avian species.

Mating frequency has important implications for patterns of sexual selection and sexual conflict and hence for issues such as speciation and the maintenance of genetic diversity. Knowledge of natural mating patterns can also lead to more effective control of pest tephritid species, in which suppression programmes, such as the sterile insect technique (SIT) are employed. Multiple mating by females may compromise the success of SIT. We investigated the level of polyandry and sperm utilization in a Brisbane field population of the tropical fruit fly, Bactrocera cacuminata (Hering), using seven polymorphic microsatellite loci. The offspring of 22 wild-caught gravid females were genotyped to determine the number of males siring each brood and paternity skew, using the programsgerud andscare. Our data showed that 22.7% of females produced offspring sired by at least two males. The mean number of mates per female was 1.72. Paternal contributions of double-sired broods were skewed with the most successful male having sired between 76.9% and 87.5% of the offspring. These results have implications for SIT, because the level of remating we have identified would indicate that wild females could mate with one or more resident fertile males. [ABSTRACT FROM AUTHOR]

1. The ‘Field of Dreams Hypothesis’ states ‘if we build it, they will come’, referring to the assumption that if habitats are restored, species will recolonise them. However, the ability of a species to recolonise a restored site will depend not only on the appropriate habitat being present, but also on the ability to get there. This is likely to depend on both the species’ dispersal behaviour and the position of a site in the landscape. 2. Animals with good potential for dispersal are more likely to be able to disperse to newly restored sites. Similarly, sites in lowland streams with limited altitudinal differences between sites may be easier to reach than upstream sites. This is because upstream sites are connected to one another via lowland streams that have different characteristics and therefore may be difficult for animals to traverse. 3. In this paper, genetic data from a range of freshwater species that have been analysed in my laboratory are used to assess the importance of life cycle and position in the landscape (i.e. upland versus lowland streams) on connectivity patterns (and thus recolonisation potential) among populations. 4. In general, contemporary dispersal across catchment boundaries is negligible, except for aquatic insects with an adult flight stage. Dispersal among streams within catchments appears to be more limited than was predicted from knowledge on life histories, except for fish in lowland rivers and streams. 5. As predicted, dispersal of fish, crustaceans and molluscs among streams within catchments is significantly greater in lowland rivers than in upland streams. 6. Overall, these analyses suggest that, with the exception of most insects, and fishes in lowland rivers, natural recolonisation of restored sites is only likely from sites within the same stream. If a species has disappeared from the whole stream, then restoration of habitat alone may not be sufficient for its re-establishment. [ABSTRACT FROM AUTHOR]

Background There is much variation in the services provided for older people with mental health problems. In England, the National Service Framework for Older People (NSFOP) sought to address these inconsistencies and improve care. This study describes the situation three years after its publication. Methods A postal survey of old age psychiatrists collected data on the NSFOP mental health model: the range of specialist mental health provision, the nature of the specialist:generic service interface and the degree of interdisciplinary/interagency working. Results Three hundred and eighteen (72%) consultants responded. Considerable differences existed in the deployment of key professionals within community teams, with more than a third lacking ring-fenced social work time. Few services had dedicated rehabilitation beds and nearly a third lacked separate facilities for people with organic and functional illnesses. Increasing numbers of consultants had access to a memory clinic and there was some suggestion that liaison services were developing, but little indication of increased support for care homes. Several services had yet to agree protocols with primary care, or to implement measures promoting effective information-sharing and integrated care, and there was little evidence that the introduction of the Single Assessment Process (SAP) had significantly changed practice. Although just over half of consultants reported that mental health services were improving, less than a quarter considered community provision adequate. Conclusions Three years after the publication of the NSFOP there remained significant gaps in services for older people with mental health problems and substantial variation in provision between districts.
