Sustainable wildlife management requires reliable data on population, habitat, and the interaction between them. Since 1993, Hungary has maintained the National Game Management Database, which collects data on game populations and hunting bags annually. During the last three decades, populations of medium-sized predators have remarkably increased in the country. Our study analyzed changes in hunting bag data and spatial distribution of two invasive alien species, the raccoon (Procyon lotor) and the raccoon dog (Nyctereutes procyonoides), utilizing annual game management reports from Game Management Units from 1997 to 2021. For spatial analysis, we employed a UTM grid system (10 × 10 km) covering the country. Our findings confirmed increasing trends in the hunting bag and area (number of grid cells) containing hunting bags for both species. From the first (1997–2001) to the last (2017–2021) period, the average annual hunting bag increased (raccoon: 0.40 → 11.00 ind/year; raccoon dog: 3.40 → 8.00 ind/year), and the average number of cells with hunting bags also expanded significantly (raccoon: 2.00 → 9.60 UTM cells/year; raccoon dog: 5.80 → 15.20 UTM cells/year). These trends and the size of potentially suitable habitats suggest a further spread and population increase, posing challenges for nature conservationists and wildlife managers.

Roe deer (Capreolus capreolus) populations have been increasing in Europe in the last decades. Without reliable methods, game managers frequently underestimate the population size, leading to underharvesting. The aim of this research was to identify the most suitable method for roe deer density estimation in lowland, sparsely forested, high-visibility flat areas in Hungary. The census data of the total counting in the daytime strip transect and the night spotlight strip transect, as the total counting of the sample areas with a thermal camera from observation points within 0–250 m and 0–500 m ranges, were compared in seven hunting areas. It was revealed that using the thermal camera within 0–250 m and the spotlight method in the same range gave the statistically highest population density values. There was no significant difference between the two methods. The smallest mean was revealed in the case of the daytime strip transect data. The thermal imaging method gave significantly lower values for the greater distance (250–500 m) than for the range of spotlighting (250 m). The night spotlight strip transect method and the counting from observation points with a thermal camera, both to 250 m, provided the highest values; thus, they are recommended to determine the roe deer population density in open flat areas. They require the same amount of human resources and time, but due to the high cost of the thermal camera, the spotlight is also perfectly suited for widespread use by hunting companies. The results supported the underestimation of roe deer populations. [ABSTRACT FROM AUTHOR]

Wild boars use a wide range of habitats. Their invasive nature is gaining attention due to the complexity of its impact. The goal of this research is to analyze the impact of the wild boar on the chemical properties of soils in a natural and a post-fire forest in the Edough Forest Massif in Algeria. This study compares the impact of wild boar rooting on soil parameters to determine the functional role of the wild boar. The research was conducted during the winter of 2022. The study sites included a natural forest and a post-fire area. Rooting tracks were geolocated and soil samples were collected. The results show significant differences between rooted and control patches in the chemical parameters measured in the two environments. However, in the natural environment, significant differences were only noted for the calcium content and electrical conductivity. But in the post-fire environment, strong significant differences were observed for all measured parameters, suggesting that wild boars do not exert a noticeable soil homogenization effect on the soil properties. This research highlights the importance of understanding and managing the impact of wild boars in natural and post-fire forests on soil formation processes, the diversity of soil properties, and their magnitude.

The natural regeneration of the temperate oak forests is often insufficient. Acorns of the oak serve as the basis of the recruitment and key food resources in these ecosystems, thus the crop size, the germination success and seed predators have crucial roles in the process. Wild boar (Sus scrofa) is often considered as one of the main mitigating agents in oak regeneration. Therefore, in our study we analyzed and compared the spatial patterns of the acorn density and the patches rooted by wild boar within and among the different examined time intervals in a 28 ha Turkey-sessile oak (Quercus cerris, Q. petraea) forest stand. Data were collected between 2016 October and 2019 December. In the acorn density patterns, intra-annual similarities were recognized mainly, regardless of the crop size. Meanwhile, rooting patterns showed inter- and intra-annual similarities in mast years and intra-annual overlaps in non-mast years, indicating that masting is a fundamental driver of wild boar foraging behavior. However, a direct local connection between the rooting intensity and the acorn density could not be shown, as wild boars never fully depleted the acorns, even in intensively used patches. This study can help in predicting the intensively rooted forest patches, providing opportunities to manage wildlife conflicts. [ABSTRACT FROM AUTHOR]

In the Hungarian Great Plain the roe deer (Capreolus capreolus) is one of the most important species for wildlife management. The supplementary feeding of roe deer in Hungary is a traditional habit, it can be beneficial for deer to survive and keep body condition during winter. In our study, we aimed to know the behavioural habits of roe deer at feeding places. The data were collected in two wildlife management units in Jász-Nagykun-Szolnok county in Hungary from the winter of 2019 until the spring of 2020. Roe deer followed a temporal trend, with higher numbers around feeders in colder months and lower numbers in warmer months. Their visits followed a bimodal activity pattern that was characterized by peaks of activity at dawn and dusk. We were able to link the presence of snow cover and precipitation to an increase in the feeding activity of roe deer. It is important to understand that the presence of deer at the feeder does not reflect the actual biological effect of the use of feeders on deer. Game managers should identify what the main goal of the feeding is and think of how to validate the effectiveness of this expensive intervention. We suggest at least measuring how much of the supplemented feed actually makes up the diet of roe deer individuals. However, it would be the most reliable approach to analyse the physiological and biological differences between fed and non-fed deer. [ABSTRACT FROM AUTHOR]

Expanding wild boar populations associate to conflicts with human activities, being a threat to livestock and public health. Particularly, the emergence of African Swine Fever (ASF) in Europe is of major importance. To better understanding the dynamics at the interface between wild boar and domestic pigs in Europe, which is essential to prevent the risk for ASF spread, this report describes (i) the use of extensive pig farm resources by wildlife (wild boar and other mammals) and domestic pigs, and (ii) the factors involved. We studied two regions of Central‐Eastern Europe with different farm management of pigs in Serbia, in low biosecurity farms in forest/bushland habitats, and Hungary, characterized by more industrial and professional farming in fenced pastures. Camera traps (CTs) were placed at a priori risk points for interspecies interactions and in random points in 4 representative outdoor pig farms in different seasons during 2022 (2 farms in Serbia and 2 in Hungary). Also, questionnaires were distributed to 37 farms (17 in Serbia and 20 in Hungary, respectively) to describe the main features and risk factors for wildlife‐pigs interaction on outdoor pig farms. CTs revealed that the wild species that more frequently used the study farms resources were golden jackal (Canis aureus) and wild boar in Serbia, and red fox (Vulpes vulpes) and red deer (Cervus elaphus) in Hungary (at the periphery of fenced farms). The use of extensive farm resources by wild boar was frequent and widespread throughout the study area of Serbia (over 33 % of daily presence per farm, 3.70 visits detected per week) whereas it was rarely detected in our sampled Hungarian farms. Wild boar visit frequency (Serbia) peaked during spring (7.5 visits per CT and day, CT*day), mainly associated with water point use (2.1 visits per CT*day). In Hungary, the greater number of direct interactions occurred between pigs and red deer during summer. Even when a higher average number of risk points were identified inside Hungarian farms, they were less permeable due to effective perimeter fencing, which prevented the entrance of wild boar and other big sized terrestrial wildlife. The study exemplifies contrasted outdoor pig farm managements, and associated risks for interaction with wild boar in ASF infected or at‐risk regions. Management, characterized by almost absence of external biosecurity in the specific type of production in Serbia raise health concerns, and indicates the need to develop efforts to improve biosecurity. Several strategies and specific measures adapted to environmental conditions and farm management could reduce the interactions at the wild boar‐pig interface in Serbia (and similar production systems in Eastern Europe). This should be materialized in farm‐specific biosecurity programs and protocols, which requires the evaluation of their effectiveness, costs, and practical value. The type of farming practiced in marginal agricultural/forest lands in Eastern Europe, often connected to backyards production, is a highly priority for biosecurity issues at European level. However, the focus should not be only on improving technical aspects of biosecurity, but also on socio‐economic and educational determinants. [ABSTRACT FROM AUTHOR]

Simple Summary: We investigated movements of the Caspian whipsnake (Dolichophis caspius) in a peri-urban habitat in Budapest, Hungary. Radiotelemetry results showed that the five tracked individuals used a larger part of habitats (40.15 ha) during warmer seasons, but a relatively smaller area (1.75 ha) of a rocky mount with a high hibernaculum density during winter periods. During the main activity season, the individual home range sizes varied between 6.1 and 15.5 ha; meanwhile, the average daily displacement of the snakes was found to be between 12.6 and 36.6 m. For this study, we can conclude that Caspian whipsnakes have enough space to move around the area for foraging, but hibernating places are limited. Human activities and anthropogenic disturbances, especially around hibernacula, may exert pressure on this peri-urban snake population. Semi-natural environments within cities can provide habitats for vulnerable reptile species. Better understanding of their habitat use and home range sizes is important for their conservation. We investigated the spatial ecology of Caspian whipsnakes (Dolicophis caspius) in a peri-urban habitat in Budapest, Hungary. We used radiotelemetry to track five adult snakes and analyzed their microhabitat preferences, home range sizes and daily movements. The Caspian whipsnakes intensively utilized areas covered with woody vegetation, with a high density of hibernacula. The tracked snakes used an area of 40.15 ha during the activity period from spring to autumn, but for the winter, they withdrew to a central area of 1.75 ha, abundant in hibernacula. During the activity period the individual home range sizes varied between 6.1 and 15.5 ha, estimated using the minimum convex polygon (MCP); however, for the entire datasets of the individuals, the adaptive kernel method gave the highest mean (13.8 ha), while the LoCoH-R yielded the smallest home ranges (5.19 ha). We found that the average daily displacement for the different individuals ranged between 12.6 and 36.6 m during their main activity season. In the study area, the whipsnakes currently have enough space for foraging, but the restricted spatial distribution of hibernacula, which is mainly available in the central dry rocky forest and partly in the shrubby areas, can limit the extent of the suitable habitat. Human activities and anthropogenic disturbances, especially around hibernacula, may exert pressure on this peri-urban snake population. [ABSTRACT FROM AUTHOR]

Human-wildlife conflicts are one of the most important challenges facing wildlife conservation. In Kenya, the Nairobi National Park (NNP) experiences various pressures due to its small size and close proximity to an expanding city. The unfenced southern part of the park is the main hotspot for conflicts. For the review a content analysis of 21 publications related to NNP published between 2011 and 2022 was conducted to identify the causes, types and the mitigation measures of conflicts around the park. Documents for the analysis were collected through Google Scholar, Web of Science and Scopus. Our results indicate that livestock predation linked to lions is the major type of conflict superseded by retaliatory killings of the carnivores by the local communities. Other conflicts include crop raids by ungulates and the spread of diseases especially the East Coast fever that is transmitted from the wildebeest to livestock. Findings further reveal that one of the main causes of the conflicts is the expanding human population, which has encroached on wildlife dispersal corridors. It resulted in land subdivision and fencing of the farms as farmers try to protect their livestock from wildlife. This has greatly impeded wildlife migration. Mitigation methods in place include compensation schemes and landowners leasing their farms to the park management so that the corridors can be left open for free wildlife movement. These have however been inadequate therefore there is still a need to find sustainable mitigation measures that ensure coexistence between humans and wildlife in and around NNP.

Several ungulate species are showing increasing population patterns within their geographical distribution ranges, leading to constant interactions with other animal species. Varying densities and activities of different ungulates may result in diverse impacts on other coexisting species groups, including large numbers of threatened species, such as reptiles. In this study, we performed an analysis of the available literature to investigate the impacts of ungulates on reptiles. We aimed to reveal the diversity of: (1) the geographical and environmental distribution of related investigations; (2) the ungulate and reptile species involved; and (3) the characteristics of interactions (direct or indirect, positive or negative) from 69 publications. Our results show that the most papers were reported from the Americas (42%) and Australia (28%). The proportions of studies were balanced for wild ungulates (53%) and livestock (47%). Wild boar (Sus scrofa) was found to be the most problematic species on reptiles whereas reptiles which suffered the harshest impacts were Squamates (i.e., lizards, and snakes). Ungulate activities (e.g., digging by wild boar) may directly harm reptiles (consuming or killing them) or indirectly affect them by modifying their habitats or destroying their hideouts. Some preferential effects were also noted (e.g., by moderate livestock grazing or when wild ungulates are prey for large reptiles). Published livestock impacts were mainly indirect and mostly negatively linked to overgrazing. We conclude that it is important to manage and monitor the densities of ungulates to minimize their negative impacts on reptile species, especially in case of wild boar and grazing livestock, but also to maintain their moderate beneficial effects (e.g., as prey basis).

Forest soils are shaped by various processes, like runoff, erosion, sedimentation and bioturbation. A better understanding of the interactions between abiotic and biotic soil-forming processes, including wild boar (Sus scrofa) rooting (i.e., subsurface foraging), enhances adequate management of forest ecosystems. We hypothesized that intense soil sedimentation influences wild boar rooting occurrence and that wild boars modify the outcome of the sedimentation process by redistributing soil layers. This study was conducted in the Babat Valley, Hungary. We estimated the availability of sedimented and non-sedimented patches and the occurrence of boar rooting. Surveys and samplings were done along transects, over consecutive months, where the impact of rooting on the physical and chemical characteristics of soil was measured by comparing them between control and rooted sites. We found that non-sedimented, steep areas were preferred areas for rooting. Sedimentation processes have a higher impact on soil chemical characteristics and soil layer composition than wild boar rooting. We conclude that mitigation of soil degradation can be more effective by reducing adverse abiotic processes rather than wild boar population control. [ABSTRACT FROM AUTHOR]

Herbivore species can either hinder or accelerate the invasion of woody species through selective utilization. Therefore, an exploration of foraging decisions can contribute to the understanding and forecasting of woody plant invasions. Despite the large distribution range and rapidly growing abundance of beaver species across the Northern Hemisphere, only a few studies focus on the interaction between beavers and invasive woody plants.We collected data on the woody plant supply and utilization at 20 study sites in Hungary, at two fixed distances from the water. The following parameters were registered: taxon, trunk diameter, type of utilization, and carving depth. Altogether 5401 units (trunks and thick branches) were identified individually. We developed a statistical protocol that uses a dual approach, combining whole‐database and transect‐level analyses to examine foraging strategy.Taxon, diameter, and distance from water all had a significant effect on foraging decisions. The order of preference for the four most abundant taxa was Populus spp. (softwood), Salix spp. (softwood), Fraxinus pennsylvanica (invasive hardwood), and Acer negundo (invasive hardwood). The diameter influenced the type of utilization, as units with greater diameter were rather carved or debarked than felled. According to the central‐place foraging strategy, the intensity of the foraging decreased with the distance from the water, while both the taxon and diameter selectivity increased. This suggests stronger modification of the woody vegetation directly along the waterbank, together with a weaker impact further from the water.In contrast to invasive trees, for which utilization occurred almost exclusively in the smallest diameter class, even the largest softwood trees were utilized by means of carving and debarking. This may lead to the gradual loss of softwoods or the transformation of them into shrubby forms. After the return of the beaver, mature stages of softwood stands and thus the structural heterogeneity of floodplain woody vegetation could be supported by the maintenance of sufficiently large active floodplains.The beaver accelerates the shift of the canopy layer's species composition toward invasive hardwood species, supporting the enemy release hypothesis. However, the long‐term impact will also depend on how plants respond to different types of utilization and on their ability to regenerate, which are still unexplored issues in this environment. Our results should be integrated with knowledge about factors influencing the competitiveness of the studied native and invasive woody species to support floodplain conservation and reconstruction.

Since 2017, grants from the National Game Management Fund have supported the development of habitats for the game species by providing hiding and feeding places for them and by the effective control of their predators. We evaluated the effects of these management actions on the local wildlife populations with a questionnaire survey among the supported game management units between 2018 and 2020. We asked them about their impressions or measured data regarding the size and quality of the game populations treated during the program. We compared the conditions before and after the interventions, specifying the methods in case of measurements. The 241 answers covered 35% of all the supported game management units. Most applicants (94%) rated their management actions as effective, while only 2% reported the contrary. Game managers collected data to measure the efficiency relatively infrequently (14±9% of the beneficiaries for each variable group in each target area, min-max: 3-44%). Much more often, they relied on non-scientific observations and perceptions (63±14%, min-max: 36-93%). We conclude that it would be necessary to evaluate the efficiency on the basis of systematic data collection and analyses (monitoring), at least with smaller samples at the level of game management units. Game managers should measure the use of the treated areas by the game species and the changes in the quantity and quality of the populations (e.g., camera trapping at drinking and feeding sites, spotlight counts of brown hares, estimating the reproduction, condition or trophy quality indices).

The common use of habitats by people and game species has been causing conflicts for a long time. With the intensification of agriculture, the level of agricultural damage has also increased. In many cases farmers and game managers try to solve their related disagreements in court, often unsuccessfully. The aim of our research was to find out the reasons for these difficulties and to show possible solutions. We studied 55 judicial documents in three courts in Nógrád County. In most cases more species caused the damages simultaneously. Red deer was involved in 42 cases of damages (76%), out of which in 34 cases wild boar, roe deer and mouflon were involved as well, and 8 damages were caused by just the red deer. Wild boar caused 33 damages (60%), out of which 29 were caused by the other species as well, and 4 cases were caused only by the wild boar. Roe deer was involved in 21 damages (38%), all of them were caused by wild boar and red deer, too. Mouflon caused 3 damages (5%) always together with roe deer and wild boar. Damages were caused mainly in maize (23,64%), forest, sunflower (12,73% for both) and grassland (5,45%). Proceedings lasted for 13,65 months on average; their median was 8 months. The average claim of farmers was 1 514 610 HUF, its median was 783 000 HUF. At the end of the suits, farmers received the whole compensation in 8 cases (14,55%) and they got part of the relief on ten occasions (18,18%). Suits were ceased 14 times (25,45%) and no compensation had to be paid in 23 cases (41,82%). If parties did not comply with their obligation to prevent damage, the court adjudged only part of the relief. Furthermore, if they turned directly to the court - even if the court could not investigate the case (e.g., claim is lower than 3 million HUF) - no compensation had to be paid. Ignorance of law and unprofessional expertise of farmers negatively influenced the judicial proceedings. Both farmers and game managers should be informed about the exact steps of the procedure for solving these long-lasting conflicts. [ABSTRACT FROM AUTHOR]

Background: Traditional knowledge is key for sustainability, but it is rapidly disappearing. Pig keeping in forests and marshes is an ancient, once widespread, now vanishing practice, with a major economic and ecological potential. The knowledge of pig keepers and the foraging activity of pigs are hardly documented. Methods: We studied the knowledge of traditional pig keepers (svinjars) on wild plants and pig foraging on the Sava-Bosut forest-marsh complex in Serbia. We conducted picture-based interviews about 234 locally common and/or salient plant species, and participatory fieldwork (11 days) and visual observation (21 days) on pig foraging. Results: 181 wild plant species were known by svinjars and 106 taxa were consumed by pigs. Svinjars knew well and could name most regularly foraged species. 98 species were reported by svinjars as foraged and 56 as not eaten. 28 species were observed by the authors as eaten regularly, while 21 were nibbled and 17 avoided. Contradictory information on foraging was rare both among svinjars (8 species) and between svinjars and researchers (7 species); several of these species were rare. Leaves of 92, fruits or seeds of 21 and 'roots' of 20 species were reported or observed as eaten, usually with high seasonality. Svinjars were overall observant, but knew little about some less salient species (e.g. Veronica, Circaea). The most common forages (reported and/or observed) were fruits (Quercus, fleshy fruits), grasses (Agrostis, Glyceria), herbs (Ranunculus ficaria, Circaea), nutritious 'roots' (Carex spp., Iris), young shrub leaves (Crataegus, Carpinus) and 'tame' plants growing in the sun (Persicaria dubia, Erigeron annuus). Traditional, now extinct pig breeds were reported as less selective and more 'knowledgeable' about plants, as they received less additional fodder. Svinjars learnt their knowledge since childhood, from community members, but long-term personal observations and everyday encounters with pigs were also important sources of knowledge. Conclusions: A deeper understanding of pig foraging could contribute to using pigs in nature conservation management, resource management and organic farming, and to a better understanding of wild boar foraging. The knowledge of svinjars is a disappearing intangible cultural heritage of European importance. Knowledge holders deserve recognition, and legal and financial support to continue this tradition.

The intensification of agriculture has resulted in changes to mowing techniques. Slow manual cutting gave wild animals time to move to safer habitat patches and left hiding places for them. With the arrival of much faster mowing machinery this is no longer the case. To date, there are few ways of measuring direct mortality of new mowing capabilities on wildlife. In our study we aimed to answer whether a search dog, previously trained to find carcasses, could be used to assess mowing mortality of various species in different vegetation types in Hungary. Working with a handler, a carcass-trained dog fitted with a GPS surveyed several habitats post-mowing. All the animal remains detected were identified and recorded. 149 killed individuals were detected on 12 land parcels studied (158.2 carcasses/100 ha). The most affected vertebrate group was the reptiles (57%), all with protected status in Hungary, followed by mammals (30%) and birds (6%). Reptiles were predominantly represented by lizards, while rodents were the most common mammals found (91% and 70%, respectively). The dog also found dead brown hares, pheasants and roe deer (11% of all carcasses), which has implications for local wildlife managers. There was no statistical difference in the density of dead individuals between grassy meadows and leguminous vegetation, or in those found in the morning or afternoon. The mortality rate was not associated with the area of the mowed field. Our findings suggest that this is a viable use of carcass detection dogs. We recommend additional work of this kind to reveal the fatal impacts of new, faster mowing practices on wildlife living in agricultural landscapes to help mitigate conservation and game management conflicts.

Objectives. The aim of this study was to analyse the composition of amyloid mass and the plasmacytic infiltrate of localized amyloidosis of the upper aerodigestive tract. Methods. Biopsy materials were studied by light microscopy, immunohistochemistry (IHC), and mRNA in situ hybridization (mRNA-ISH). The amyloid mass was also analysed with high-performance liquid chromatography mass spectrometry- (HPLC-MS-) based proteomics. Results. Nodular and diffuse forms of amyloid deposition were detected. IHC analysis revealed λ-light chain (LC) in two cases, κ-LC in one case. The remaining two were positive with both. Proteins, well known from other amyloidoses like amyloid A (AA), prealbumin/transthyretin (PA), apolipoprotein A-I (ApoAI), and amyloid P component (APC), and also keratin were found with variable intensities in the cases. HPLC-MS revealed dozens of proteins with both LCs in all the lesions but sometimes with surprisingly small intensities. mRNA-ISH analysis revealed identical λ and κ dominance and only one normal κ/λ cell ratio. Conclusion. Cellular infiltrate and protein components in the amyloid showed congruent results in all but one case. The only exception with normal cell ratio and λ-dominant amyloid could be originated from the different protein-secreting activity of plasma cell clones. HPLC-MS analysis explored both LCs in all the amyloid in variable amount, but other proteins with much higher intensities like keratins, apolipoprotein A-IV (ApoAIV), were also detected. Proteins like AA, PA, ApoAI, and APC, previously known about amyloid-forming capability, also appeared. This indicates that localized amyloid in the upper aerodigestive tract is not a homogenous immunoglobulin mass but a mixture of proteins. The sometimes very low light chain intensities might also suggest that not all the localized amyloidosis cases of the upper aerodigestive tract are of convincingly AL type, and the analysis of the cellular infiltrate might indicate that not all are monoclonal.

Background: Fatty infiltration of minor salivary gland parenchyma is relatively frequent, but not extensively examined histopathological phenomenon in biopsy samples. Its extent and relation to several suspected background diseases are not well understood.Methods: In this study, we examined the presence and extent of fatty infiltration on digitally scanned versions of the periodic acid/Schiff-stained minor salivary gland slides of 275 patients. As a result of the image analysis, fatty infiltration was expressed in per cent of the whole selected area. The presence and extent of this change were compared to age, diabetes mellitus and body mass index in various statistical analyses.Results: Significantly higher age and body mass index values were found in the fatty infiltration positive than in the negative group. We also found that not only the number of fatty infiltration positive cases was increased significantly in the gradually worsened body mass index groups, but the extent of fatty infiltration also increased as the obesity worsened. Age also showed significant correlation with the extent of fatty infiltration.Discussion: All of these findings support that the age (which seemed the only independent variable) shows strong correlation with the presence of the fatty infiltration but obesity may also play important role in the development and the extent of this change. Because of its frequency in elderly, at least partly, the fatty infiltration might be responsible for the xerostomia. We also think that presence of fatty infiltration should be mentioned in the histopathological report of salivary gland biopsies. [ABSTRACT FROM AUTHOR]

We allocated some new types of bait traps using different volatile aromatic compounds in the Velyka Dobron' Game Reserve (Ukraine, Transcarpathian region) where light trap surveys on Macroheterocera were already carried out since 2009. The phenylacetaldehyde-based traps were especially effective for the species of subfamilies Plusiinae and Heliothinae, while the members of some other subfamilies (Hadeninae, Noctuinae) were more attracted by the isoamyl-alcohol-based traps. The highest attractivity was observed in case of the mixture containing isoamyl-alcohol, acetic acid and red wine. The highest number of species was observed in mid-July, but the peak of individual numbers appeared in early August. Majority of species of this assemblage was formed by bivoltine species connected to herbaceous food plants. The dominant species of this late summer period was Trachea atriplicis (second brood). It was sharply replaced by the monovoltine Allophyes oxyacanthae in September. The bulk of species of this early autumnal period was formed by monovoltine species with woody-shrubby larval food plants. Biogeographical spectrum of the assemblage was dominated by widely distributed Euro-Siberian species combined with significant presence of Mediterranean and Boreo-continental faunal elements. In the ecological spectrum of the assemblage the species connected to forested habitats are well represented but together with the presence of numerous generalist species. [ABSTRACT FROM AUTHOR]

Debarking by ungulates has various effects on stem development and forest tree composition. Selectivity for debarking may prevail based on tree species and stem girth. We investigated this selective utilization based on species and size composition of available and debarked stems. Measurements were taken on 2100 sampling points in different temperate deciduous forests of Mátra Mountains region, Hungary. We distinguished specific stem injuries from each other. Factors influencing debarking (stem density and diversity, understory browsing) were also studied. Frequency of debarking was very low (5 % of sampling points). It was the lowest in beech forests (0.2 %) and the highest in Turkey oak-sessile oak forests (6 %). The proportion of injured stems varied between 0.001 % in beech forests to 0.04 % in Turkey oak-sessile oak forests. Ash, linden and maple trees were the most utilized; ash was revealed as significantly preferred species. Most of the injured stems had a perimeter between 12 and 21 cm, proved as preferred stem size interval. Trunks larger than 50 cm girth were generally avoided. Bark stripping and antler rubbing occurred mainly on thinner ash stems, whereas bark rubbing on larger oak stems. Understory density and diversity was significantly higher at debarked sampling points than intact ones. Ungulate debarking is functioning as selective natural disturbance. As a driver of forest vegetation dynamics, its total elimination should not be targeted from forest ecosystems. We recommend maintaining a diverse forest composition to ensure selective stem utilization of ungulates and reduce damage on major tree species of economic importance. [ABSTRACT FROM AUTHOR]

Winter supplementary feeding is widespread in large game management. As it is very expensive, it is important to know how essential this feeding may be for populations of game like red deer Cervus elaphus . Game managers typically observe only the disappearance of feed, but do not measure the consumption from the perspective of the animal, so the importance of feeding programs is often uncertain. During the winter of 2007 - 2008 we determined the consumption by red deer of two feed types (maize silage and apple pomace which is the residue from pressing apples) commonly offered at feeding plots in Hungary in two study areas. We simultaneously utilised two complementary methods: microhistological analysis of faeces and rumen content, and macroscopic observation of natural and artificially mixed food markers. Based on our analyses, 20 to 90% of the red deer (among different dates and measures) had eaten the supplementary food. However, the proportion of supplementary food in the red deer droppings collected in the immediate surroundings of the feeding plots was always very low (< 10%). Th is indicates that not every individual of the red deer population visits the feeders, or if does, eats a rather small amount of the provided food. Our data strongly suggests that supplementary food did not play a large role in the diet of the red deer individuals regularly visiting these sites. We emphasise that the mere observation that supplementary food regularly vanishes from the feeder does not necessarily mean that even one individual red deer has gained a significant biological advantage which would result in additional financial profit for the game manager later. Managers considering supplementary feeding should evaluate the quality of the forest area because the natural food supply can greatly influence the use of the feeding plots. [ABSTRACT FROM AUTHOR]

Fatty infiltration in minor salivary gland biopsies and its correlation to systemic autoimmune diseases are controversial in the literature. Presence and extent of fatty infiltration in minor salivary glands of 107 Sjögren’s syndrome patients and 67 age-matched sicca controls were compared with statistical analyses. No significant difference was found regarding the presence or the extent of fatty infiltration between the two groups. Fatty infiltration seems to be unrelated to Sjögren’s syndrome thus its examination in salivary gland biopsy samples cannot improve the diagnostic accuracy of the disease. [ABSTRACT FROM PUBLISHER]

Climate change can result in a slow disappearance of forests dominated by less drought-tolerant native European beech ( Fagus sylvatica) and oak species ( Quercus spp.) and further area expansion of more drought-tolerant non-native black locust ( Robinia pseudoacacia) against those species in Hungary. We assumed that the shift in plant species composition was modified by selective ungulate browsing. Thus, we investigated which woody species are selected by browsing game. We have collected data on the species composition of the understory and the browsing impact on it in five different Hungarian even-aged forests between 2003 and 2005. Based on these investigations the non-native Robinia pseudoacacia living under more favourable climatic conditions was generally preferred (Jacobs' selectivity index: D = 0.04 ± 0.77), while the native Fagus sylvatica and Quercus spp. ( Q. petraea, Q. robur), both more vulnerable to increasing aridity, were avoided ( D = −0.37 ± 0.11; −0.79 ± 0.56; −0.9 ± 0.16; respectively) among target tree species. However, economically less or not relevant species, e.g. elderberry ( Sambucus spp.), blackberry ( Rubus spp.) or common dogwood ( Cornus sanguinea) were the most preferred species ( D = 0.01 ± 0.71; −0.12 ± 0.58; −0.2 ± 0.78, respectively). Our results imply that biodiversity conservation, i.e. maintaining or establishing a multi-species understory layer, can be a good solution to reduce the additional negative game impact on native target tree species suffering from drought. Due to preference for Robinia pseudoacacia selective browsing can decelerate the penetration of this species into native forest habitats. We have to consider the herbivorous pressure of ungulates and their feeding preferences in planning our future multifunctional forests in the light of climate change impacts. [ABSTRACT FROM AUTHOR]

Mus spicilegus has become a popular biological model species in the last decade because of the evolutionary interest of its behavioural particularities (the building of mounds, bi-parental care and monogamous mating system). The genetic structure of M. spicilegus populations should reflect those life-history traits. Although many studies have reported on mound-building mouse populations in the field or in a semi-natural enclosure, only one used hyper variable genetic markers to assess parentage and social structure. In the present study conducted in Hungary, we analysed individuals from seven highly populous mounds in autumn with the set of loci used in a previous study. Our results confirmed that mounds are inhabited by juveniles from several parental units, but revealed population differences. In a capture–recapture field session in spring, we assessed genetic relationships between individuals after dispersal from the mounds, the other key moment of the life cycle of this species. The results indicate that the social structure at this moment reflects a transition phase between the large over-wintering groups and the monogamous pairs described later in the year. Social bounds forged during the long winter cohabitation may have lasting effects on social and genetic structure of this species. This scenario is discussed in respect of the available literature on this species as well as other species. © 2008 The Linnean Society of London, Biological Journal of the Linnean Society, 2008, 93, 689–699.

Many red deer (Cervus elaphus) inhabit nonnative Scots pine (Pinus sylvestris) and black locust (Robinia pseudoacacia) forested areas with impoverished shrub understory in the Hungarian Plains. Nonnative plants can displace native plant species and alter wildlife habitat use, but few studies have investigated the relationship between the characteristics of these forests and red deer resource use. We investigated whether forest type (main tree species), rate of the main tree species, and age class of nonnative stands determine the typical distribution of certain browse species at the shrub layer. We also examined whether we could predict red deer use of the various forests. We quantified the canopy cover of understory browse and estimated deer diet using microhistological analysis of composite fecal samples collected at 2-4 week intervals between May and November 2000. We also evaluated the habitat use of 3 radiomarked deer in the study area from 1995 to 2001. No significant correlation could be drawn between the characteristics of forest stands and browse at shrub level according to forest types, rate of main tree species, age classes, and canopy cover of the dominant browse species. Red deer consumed mainly browse species (63%) complemented by forbs (31%). The dominant browse species in the diet were black locust (75-71%) and elder (Sambucus nigra; 75-27%). The predominant browse species in the forests were black locust, tree of heaven (Ailanthus altissima), western hackberry (Celtis occidentalis), hawthorn (Crataegus monogyna), elder, and rare browse species categorized as OTHERS. Each browse species formed separate patches--where its cover was significantly higher (range = 45-85%) within the patch than outside (range = 5-9%)--that made up 70% of the lowland forest. Deer occupied habitats containing 1-3 browse clusters. Browse species coverage differed according to individual core areas for deer, but the total browse cover (40%) within the core areas was...

Factors affecting the population density and daily pattern of activity of the European ground squirrelSpermophilus citellus (Linnaeus, 1766) were studied in two habitats of the Kiskunság National Park, Hungary. One habitat was dominated by sandy and the other by salty grassland. Population densities were estimated by counting ground squirrel burrow entrances in sample areas with different microhabitat characteristics. Three categories (elevated, level and depressed) were used to describe the spatial distribution of burrows according to microtopography. Daily activity was evaluated by counting the ground squirrels visible on the surface and registering their alarm calls. The highest proportion of ground squirrel holes was found on elevations in the two habitats. Ground squirrels showed a similar daily activity pattern in different areas and in the same season in consecutive years. The daily activity consisted in a morning peak, a midday pause and a less regular afternoon activity period. Human activity had no direct effect on the daily activity pattern. Emission of alarm calls peaked in June, when litters emerge from the maternal burrows. [ABSTRACT FROM AUTHOR]
