The ongoing transition within forest management towards more biodiversity-oriented practices, such as close-to-nature forestry and retention forestry, may benefit fauna forest-specialized ground beetles (Coleoptera: Carabidae). However, it remains unclear how carabids are jointly affected by these practices in Central European montane forests, which host particularly sensitive, range-restricted carabid species, where is widely applied. Moreover, roe deer (Capreolus capreolus), the most common large herbivore intensively managed to reduce browsing pressure, but yet unknown this affect carabids, alongside effect of silviculture. On 66 1-ha plots Black Forest region Germany, we sampled with pitfall traps, measured abundances using camera trapping, several structural variables directly related well describing microclimate landscape-level cover. We found that assemblage was dominated specialists, little influence from fragmentation surrounding forest. Higher broadleaf share (and canopy cover for specialists) correlated higher activity-density. Increasing stand maturity lying deadwood volume specialists), species richness.

Intensive forest management has promoted an increase in deer (Cervidae) population density. Various silvicultural activities, such as pre-commercial thinning, can change the feeding conditions for species, therefore impacting browsing pressure on target tree species. In this study, we analyzed how several factors, including density of main admixture, undergrowth, and type, affect damage intensity pine stands, considering densities regional aspects hemiboreal Latvia. GLMM analysis, based data from 1238 sample plots, showed that probability decreases with undergrowth young (<20 years) stands a dominant height below 3 m. Also, pines being damaged by was significantly (p = 0.001) higher fresh thinning than those no thinning. However, differences between regions also determined pressure. Results indicated density, may be important drivers levels, especially winter wet mineral soils. Therefore, future research should continue to evaluate applied strategies forests provide additional natural food base form woody plants shrubs forage ensure more deer-adapted practices.

Abstract The study aimed to compare the chemical composition (proximate, mineral, fatty acid, and amino acid composition) nutritional value of meat from three deer species (fallow deer, red roe deer). A total eighteen male carcasses were collected. Proximate ( M. longissimus lumborum ) did not differ among species, while affected content most minerals (Ca, P, Na, Mg, Fe, Mn, Zn). In present analysis profile showed that polyunsaturated (PUFA) saturated ratio n-6/n-3 PUFA were, for all within recommended values. Furthermore, based on indexes (n-6/n-3 ratio, atherogenicity index, hypocholesterolaemic hypercholesterolaemic nutrition index), it is concluded had highest, fallow lowest nutritive value. Although certain essential acids (isoleucine valine) was lower in than (p≤0.05), non-essential higher two other (p≤0.05).

Occupancy and N-mixture analyses have been successfully used to understand habitat use in various species. However, since these methods fundamentally answer different questions about wildlife distribution, the results from each modelling approach may provide insights into species’ use. In this study, we leveraged data a long-term camera trapping study northeastern Türkiye compare occupancy analyses, with main objective of understanding how can influence our knowledge Specifically, compared preferences for three carnivore species varying baseline abundances. Our evidence that sensitivity environmental anthropogenic factors. Whereas analysis provides relatively broad summary factors affect where or not be located on landscape which areas they more likely over certain time period, degree at individual sites, particular emphasis being able deduce small-scale changes across landscape.

Abstract Selective browsing by deer on young trees may impede the management goal of increasing forest resilience against climate change and other disturbances. Deer population density is often considered main driver impacts trees, however, a range variables such as food availability also affect this relationship. In study, we use survey data from 135 research plots to explore patterns roe ( Capreolus capreolus ) pressure woody plants in mountainous forests central Europe. We fitted species‐specific generalised linear mixed models for eight taxa, assessing potential effects understory characteristics, abundance lying deadwood intensity.

Overall, results indicate preference intensity processes partly vegetation. Current strategies aim reduce through culling be inefficient they do address drivers pressure.

In recent decades, there has been an increase in European wild ungulate populations, often associated with a decline health and spread of disease. This is true for the roe deer (Capreolus capreolus), most common cervid, populations apparently affected by fibropapillomatosis, increasingly cancer. To date, however, little research into this disease, thus many interactions remain unclear descriptions tumour composition are poorly validated. The main aim present study was to evaluate presence concentration toxic heavy metals skin tumours. Our results confirmed virtually all tested for, i.e., Pb, Hg, Cd, As, Cr, Mn, Al, Co, Cu, Ni, Se, Zn, Fe, highest average concentrations found Cr (0.99 mg/kg−1 ± 2.23 SD), Cd (0.03 0.03 Hg (0.02 0.02 exceeding FAO limits meat from slaughtered animals.
