Abstract

Litter decomposition is a key ecosystem function in forests and varies in response to a range of climatic, edaphic, and local stand characteristics. Disentangling the relative contribution of these factors is challenging, especially along large environmental gradients. In particular, knowledge of the effect of management options, such as tree planting density and species composition, on litter decomposition would be highly valuable in forestry. In this study, we made use of 15 tree diversity experiments spread over eight countries and three continents within the global TreeDivNet network. We evaluated the effects of overstory composition (tree identity, species/mixture composition and species richness), plantation conditions (density and age), and climate (temperature and precipitation) on mass loss (after 3 months and 1 year) of two standardized litters: high-quality green tea and low-quality rooibos tea. Across continents, we found that early-stage decomposition of the low-quality rooibos tea was influenced locally by overstory tree identity. Mass loss of rooibos litter was higher under young gymnosperm overstories compared to angiosperm overstories, but this trend reversed with age of the experiment. Tree species richness did not influence decomposition and explained almost no variation in our multi-continent dataset. Hence, in the young plantations of our study, overstory composition effects on decomposition were mainly driven by tree species identity on decomposer communities and forest microclimates. After 12 months of incubation, mass loss of the high-quality green tea litter was mainly influenced by temperature whereas the low-quality rooibos tea litter decomposition showed stronger relationships with overstory composition and stand age. Our findings highlight that decomposition dynamics are not only affected by climate but also by management options, via litter quality of the identity of planted trees but also by overstory composition and structure.

Abstract

Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance and composition. In particular, the effects of climate and atmospheric nitrogen (N) deposition on litter decomposition and its temporal dynamics are of significant importance, since their effects might change over the course of the decomposition process. Within the TeaComposition initiative, we incubated Green and Rooibos teas at 524 sites across nine biomes. We assessed how macroclimate and atmospheric inorganic N deposition under current and predicted scenarios (RCP 2.6, RCP 8.5) might affect litter mass loss measured after 3 and 12 months. Our study shows that the early to mid-term mass loss at the global scale was affected predominantly by litter quality (explaining 73% and 62% of the total variance after 3 and 12 months, respectively) followed by climate and N deposition. The effects of climate were not litter-specific and became increasingly significant as decomposition progressed, with MAP explaining 2% and MAT 4% of the variation after 12 months of incubation. The effect of N deposition was litter-specific, and significant only for 12-month decomposition of Rooibos tea at the global scale. However, in the temperate biome where atmospheric N deposition rates are relatively high, the 12-month mass loss of Green and Rooibos teas decreased significantly with increasing N deposition, explaining 9.5% and 1.1% of the variance, respectively. The expected changes in macroclimate and N deposition at the global scale by the end of this century are estimated to increase the 12-month mass loss of easily decomposable litter by 1.1-3.5% and of the more stable substrates by 3.8-10.6%, relative to current mass loss. In contrast, expected changes in atmospheric N deposition will decrease the mid-term mass loss of high-quality litter by 1.4-2.2% and that of l

Abstract

Background: Peripartum cardiomyopathy (PPCM) shares some clinical features with idiopathic dilated cardiomyopathy, a disorder caused by mutations in over 40 genes, including TTN, which encodes the sarcomere protein titin. Methods: We sequenced 43 genes, with variants that have been associated with dilated cardiomyopathy, in 172 women with peripartum cardiomyopathy. We compared the prevalence of different types of variant (nonsense, frameshift, and splicing) in these women with the prevalence of these variants in persons with dilated cardiomyopathy and population controls. Results: We identified 26 distinct rare truncating variants in eight genes in women with PPCM. The prevalence of truncating variants (26 in 172 [15%]) was significantly higher than in a reference population of 60,706 individuals (4.7%, P=1.3x10-7), but was similar to a cohort of 332 dilated cardiomyopathy cases (55 in 332 [17%], P=0.81). Two thirds of identified truncating variants were in TTN ([10%], P=2.7x10-10 versus 1.4% in reference population), almost all located in the titin A-band. Seven of the TTN truncating variants were previously reported in cases of idiopathic dilated cardiomyopathy. In a clinically well-characterized cohort of women with PPCM (n=83), the presence of TTN truncating variants correlated with lower ejection fraction at one-year follow-up (P=0.005). Conclusions: The distribution of truncating variants in a large series of women with PPCM is remarkably similar to that found in idiopathic dilated cardiomyopathy. TTN truncating variants are the most prevalent genetic predisposition of each disorder.

Abstract

The overarching aim of the atlas is to communicate the potential risks of climatic change to the future of European butterflies. The main objectives are to: (1) provide a visual aid to discussions on climate change risks and impacts on biodiversity and thus contribute to risk communication as a core element of risk assessment; (2) present crucial data on a large group of species which could help to prioritise conservation efforts in the face of climatic change; (3) reach a broader audience through the combination of new scientific results with photographs of all treated species and some straight forward information about the species and their ecology. The results of this atlas show that climate change is likely to have a profound effect on European butterflies. Ways to mitigate some of the negative impacts are to (1) maintain large populations in diverse habitats; (2) encourage mobility across the landscape; (3) reduce emissions of greenhouse gasses; (4) allow maximum time for species adaptation; (4) conduct further research on climate change and its impacts on biodiversity. The book is a result of long-term research of a large international team of scientists, working at research institutes and non-governmental organizations, many within the framework of projects funded by the European Commission.

Abstract

In het Natuurbeleidsplan zijn voor de Provincie Gelderland indicatief 23 ecologische verbindingszones aangegeven. In het provinciaal Waterhuishoudingsplan en het Streekplan is de EHS van Gelderland verder uitgewerkt en zijn in totaal 35 verbindingszones aangegeven. Momenteel worden deze verbindingszones door de Provincie concreter uitgewerkt. Hierbij wordt gekeken voor welke doelsoorten de verbindingen van belang zijn en welke eisen deze soorten aan verbindingsbanen stellen. Verschillende soorten dagvlinders en libellen zijn ook doelsoorten in het rijksbeleid en stellen in vergelijking met bovengenoemde soortgroepen aanvullende eisen aan de samenstelling en structuur van de vegetatie in verbindingszones. Bovendien is de verspreiding van dagvlinders en libellen in Gelderland goed bekend en is de isolatie van populaties een van de oorzaken van de achteruitgang van veel soorten. In dit rapport wordt daarom ingegaan op de eisen van deze twee insectengroepen aan de verbindingszones in Gelderland.

Abstract

Specialization is an important attribute of a biological control agent. The maritime pine bast scale, Matsucoccus feytaudi Ducasse (Hemiptera Matsucoccidae), is an invasive species in Southeast France and the North of Italy. Iberorhyzobius rondensis Eizaguirre (Coleoptera: Coccinellidae), is a recently described ladybird species. Both adults and larvae are predaceous, feeding on egg masses of M. feytaudi, and are strongly attracted to M. feytaudi’s sex pheromone. To evaluate the potential of I. rondensis as a biocontrol agent of the scale, we studied its niche breadth and prey range with emphasis on pine forests and hemipterans as tested prey. In this study, I. rondensis was found to achieve complete development only when fed on M. feytaudi egg masses (92.9% survival) and an artificial prey: eggs of Ephestia kuehniella Zeller (27.6% survival). From the 2nd instar onwards, complete development could be achieved using other prey species, although larvae had significantly higher mortality and slower development. In choice tests, M. feytaudi was the preferred prey. Surveys of the ladybird populations in the Iberian Peninsula revealed that it was found exclusively on Pinus pinaster Aiton, the sole host of M. feytaudi. The unusual specialization of I. rondensis, among other predaceous ladybirds, makes it an appropriate candidate for classical biological control of M. feytaudi. [ABSTRACT FROM PUBLISHER]

Abstract

During the last decades, an increasing number of predators were found to use specific prey pheromones as chemical cues. Beyond its ecological relevance, this knowledge has practical applications on insect conservation and pest control. In this study, we present first evidence that two species of the family Dasytidae (Coleoptera) Aplocnemus brevis Rosenhauer and A. raymondi Sainte-Claire Deville use the sex pheromone of the pine bast scale Matsucoccus feytaudi Ducasse (Hemiptera: Matsucoccidae) as kairomone to locate this prey. The feeding habits and biology of Aplocnemus species are practically unknown. In the laboratory, the adults of Aplocnemus sp. accepted M. feytaudi egg masses as food source as well as other diets. Females represented more than 90% of Aplocnemus sp. attracted to the pheromone lures. We believe that females use this olfactory cue to locate suitable places for oviposition and that larvae are the predators of Matsucoccus. This study further demonstrates that the response to the kairomone elicited short prey searching times, about 23% of the individuals appeared less than 12 min after lure exposure, being consistent with the hypothesis of prey specialization. Habitat and geographical distribution predict an ancestral association of A. brevis with M. feytaudi and of A. raymondi with M. pini. Nevertheless, a recent prey shift of A. raymondi to the invasive M. feytaudi in Corsica is in progress. [ABSTRACT FROM PUBLISHER]

Abstract

Abstract Understanding the distribution of human genetic variation is an important foundation for research into the genetics of common diseases. Some of the alleles that modify common disease risk are themselves likely to be common and, thus, amenable to identification using gene-association methods. A problem with this approach is that the large sample sizes required for sufficient statistical power to detect alleles with moderate effect make gene-association studies susceptible to false-positive findings as the result of population stratification 12. Such type I errors can be eliminated by using either family-based association tests or methods that sufficiently adjust for population stratification 345. These methods require the availability of genetic markers that can detect and, thus, control for sources of genetic stratification among populations. In an effort to investigate population stratification and identify appropriate marker panels, we have analysed 11,555 single nucleotide polymorphisms in 203 individuals from 12 diverse human populations. Individuals in each population cluster to the exclusion of individuals from other populations using two clustering methods. Higher-order branching and clustering of the populations are consistent with the geographic origins of populations and with previously published genetic analyses. These data provide a valuable resource for the definition of marker panels to detect and control for population stratification in population-based gene identification studies. Using three US resident populations (European-American, African-American and Puerto Rican), we demonstrate how such studies can proceed, quantifying proportional ancestry levels and detecting significant admixture structure in each of these populations.

Abstract

Abstract Admixture is an important evolutionary force that can and should be used in efforts to apply genomic data and technology to the study of complex disease genetics. Admixture linkage disequilibrium (ALD) is created by the process of admixture and, in recently admixed populations, extends for substantial distances (of the order of 10 to 20 cM). The amount of ALD generated depends on the level of admixture, ancestry information content of markers and the admixture dynamics of the population, and thus influences admixture mapping (AM). The authors discuss different models of admixture and how these can have an impact on the success of AM studies. Selection of markers is important, since markers informative for parental population ancestry are required and these are uncommon. Rarely does the process of admixture result in a population that is uniform for individual admixture levels, but instead there is substantial population stratification. This stratification can be understood as variation in individual admixtures and can be both a source of statistical power for ancestry-phenotype correlation studies as well as a confounder in causing false-positives in gene association studies. Methods to detect and control for stratification in case/control and AM studies are reviewed, along with recent studies showing individual ancestry-phenotype correlations. Using skin pigmentation as a model phenotype, implications of AM in complex disease gene mapping studies are discussed. Finally, the article discusses some limitations of this approach that should be considered when designing an effective AM study.

Abstract

Este artículo contiene 18 páginas, 5 tablas, 4 figuras., Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance and composition. In particular, the effects of climate and atmospheric nitrogen (N) deposition on litter decomposition and its temporal dynamics are of significant importance, since their effects might change over the course of the decomposition process. Within the TeaComposition initiative, we incubated Green and Rooibos teas at 524 sites across nine biomes. We assessed how macroclimate and atmospheric inorganic N deposition under current and predicted scenarios (RCP 2.6, RCP 8.5) might affect litter mass loss measured after 3 and 12 months. Our study shows that the early to mid-term mass loss at the global scale was affected predominantly by litter quality (explaining 73% and 62% of the total variance after 3 and 12 months, respectively) followed by climate and N deposition. The effects of climate were not litter-specific and became increasingly significant as decomposition progressed, with MAP explaining 2% and MAT 4% of the variation after 12 months of incubation. The effect of N deposition was litter-specific, and significant only for 12-month decomposition of Rooibos tea at the global scale. However, in the temperate biome where atmospheric N deposition rates are relatively high, the 12- month mass loss of Green and Rooibos teas decreased significantly with increasing N deposition, explaining 9.5% and 1.1% of the variance, respectively. The expected changes in macroclimate and N deposition at the global scale by the end of this century are estimated to increase the 12-month mass loss of easily decomposable litter by 1.1– 3.5% and of the more stable substrates by 3.8–10.6%, relative to current mass loss.In contrast, expected changes in atmospheric N deposition will decrease the mid-term mass loss of high-quality litter by 1.4–2.2% and that of low-quality litter by 0.9–1.5% in the temperate biome. Our results suggest that projected increases in N deposition may have the capacity to dampen the climate-driven increases in litter decomposition depending on the biome and decomposition stage of substrate., This work was performed within the TeaComposition initiative, carried out by 190 institutions worldwide.

Abstract

Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the controls on the terrestrial carbon transfer to the atmosphere. However, previous studies were mostly based on site-specific litter and methodologies, adding major uncertainty to syntheses, comparisons and meta-analyses across different experiments and sites. In the TeaComposition initiative, the potential litter decomposition is investigated by using standardized substrates (Rooibos and Green tea) for comparison of litter mass loss at 336 sites (ranging from -9 to +26 °C MAT and from 60 to 3113 mm MAP) across different ecosystems. In this study we tested the effect of climate (temperature and moisture), litter type and land-use on early stage decomposition (3 months) across nine biomes. We show that litter quality was the predominant controlling factor in early stage litter decomposition, which explained about 65% of the variability in litter decomposition at a global scale. The effect of climate, on the other hand, was not litter specific and explained

Context: Reported literatures revealed the problems of access and misconceptions, low contraceptive usage and high unmet need for family planning among the tribes., Aims: Our aim was to find out the prevalence of contraceptive usage, unmet need and their determinants among tribal married reproductive women., Settings and Design: A community-based, observational, analytical research using cross-sectional design was conducted among 290 tribal women of the Nadia district of West Bengal., Subjects and Methods: After obtaining ethical clearance, an interviewer-administered pre-designed, structured proforma was used to collect information on socio-demographic attributes, marital history, contraceptives and fertility status, unmet needs and the reasons for not using contraceptives., Statistical Analysis Used: Bi-variate analysis was used to know the differences and a two-tailed significance test with a P value of 0.05 or less was considered statistically significant., Results: The present study revealed a high prevalence of teenage marriage (60.7%) and pregnancy (27.6%). Every one in six tribal women was illiterate. The contraceptive prevalence rate was 43.8%. Tubectomy (38.6%) was the most common method (38.6%) and unfelt need (19.6%) was the most common reason for non-use. Age, occupation of women, social class, living status, marital duration, number of living children and desire to have a future child were found to be associated with the current contraceptive use. Social class, number of living children, contraceptive awareness, source and place of availability, abortion history, opposition from family and husband, and husband participation all were significantly associated with the unmet need for family planning., Conclusion: In-depth counselling focusing on achieving a satisfactory level of awareness and acceptance of family planning methods may help to achieve reproductive health by reducing unmet needs., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

Abstract

Context: Diabetes distress (DD) is a common psychological condition distinct from depression. This is a unique, hidden emotional burden and worry that the patient experiences under ongoing treatment., Aim: To assess the prevalence and predictors of DD among adult diabetics attending a tertiary healthcare facility., Settings and Design: This hospital-based observational, analytical, cross-sectional study recruited 152 adult patients with type 2 diabetes., Materials and Methods: The sociodemographic and diabetes-related information was collected with the help of a predesigned, structured proforma. Clinical and anthropometric examinations were conducted. Distress was determined by the standardized Diabetic Distress Scale (DDS). Statistical Analysis Used: The mean (SE) value was calculated for quantitative variables. The mean item score in DDS of ≥2 is taken as the presence of distress. Fisher's exact Chi-square test was done to check for association. Two-tailed significance test with a P value of < 0.05 was considered statistically significant., Results: Majority of study participants were literate, married, and from the lower middle socioeconomic class. High blood pressure was the most common co-morbidity and tobacco use was the most prevalent addiction. The prevalence of diabetes distress was 77.0%. Emotional DD was found to be more common than regimen, interpersonal, and physician-related DD. The major determinants that emerged were young age, low socioeconomic class, physical inactivity, longer time duration to reach the hospital, associated known co-morbidities, and poor glycaemic control., Conclusion: A target-specific and routine counseling sessions merged with pronged strategic services are essential to improve the mental health of respondents., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

Abstract

Next-generation biomonitoring proposes to combine machine-learning algorithms with environmental DNA data to automate the monitoring of the Earth's major ecosystems. In the present study, we searched for molecular biomarkers of tree water status to develop next-generation biomonitoring of forest ecosystems. Because phyllosphere microbial communities respond to both tree physiology and climate change, we investigated whether environmental DNA data from tree phyllosphere could be used as molecular biomarkers of tree water status in forest ecosystems. Using an amplicon sequencing approach, we analysed phyllosphere microbial communities of four tree species (Quercus ilex, Quercus robur, Pinus pinaster and Betula pendula) in a forest experiment composed of irrigated and non-irrigated plots. We used these microbial community data to train a machine-learning algorithm (Random Forest) to classify irrigated and non-irrigated trees. The Random Forest algorithm detected tree water status from phyllosphere microbial community composition with more than 90% accuracy for oak species, and more than 75% for pine and birch. Phyllosphere fungal communities were more informative than phyllosphere bacterial communities in all tree species. Seven fungal amplicon sequence variants were identified as candidates for the development of molecular biomarkers of water status in oak trees. Altogether, our results show that microbial community data from tree phyllosphere provides information on tree water status in forest ecosystems and could be included in next-generation biomonitoring programmes that would use in situ, real-time sequencing of environmental DNA to help monitor the health of European temperate forest ecosystems., (© 2023 The Authors.
