    Opis:
    The aim of the study was to assess the diet composition of four carnivore species inhabiting the Gorce National Park (Western Carpathians, S Poland), i.e., grey wolf (Canis lupus), Eurasian lynx (Lynx lynx), red fox (Vulpes vulpes), and pine marten (Martes martes). The food analysis was based on scats collected between June 2016 and February 2017 along seven transects of a total length 96.13 km. Altogether 187 faeces were found, 95 of grey wolf, 20 of lynx, 49 of red fox, and 23 of pine marten, respectively. The dominant food category of wolf and lynx were ungulates, comprising respectively 98% and 95% of the consumed biomass. The trophic niche overlap between wolf and lynx was very high (Pianka’s index Ojk=0.99). However, there were differences in the consumed prey species. Wolves fed on red deer (Cervus elaphus), roe deer (Capreolus capreolus) and wild boar (Sus scrofa), while lynxes foraged equally on two ungulates, red deer and roe deer. Medium−sized carnivores showed greater variety in consumed food. Both pine marten and red fox had higher values of Levins’ index of the trophic niche breadth than larger carnivores and highly overlapped their diets (Ojk=0.96). Pine marten and red fox consumed mostly small mammals. Additionally, martens consumed frequently fruits, whereas red foxes foraged on carrion of ungulates. This might explain the fact that wolf and lynx overlapped their trophic niches more with red fox than with the pine marten.

    Opis:
    Coarse woody debris constitutes an important and often indispensable habitat component for a huge number of vertebrates dwelling in temperate forests. The paper collates the results of research on the impact of coarse woody debris on the functioning of the Rodentia and Soricomorpha populations. In reference to this groups of vertebrates, the subject has been well−documented in the North America. Nevertheless, with regard to small European mammals the issue has not yet been fully recognized. The paper constitutes a review of the available literature on the matter. The cited research revealed that coarse woody debris, in its different decomposition stages, increases the heterogeneity of a habitat. Creating unique micro−habitats for small mammals of high environmental demands, it offers refuge, reproduction site and rich source of nourishment. The abundance of coarse woody debris may have an indirect impact on a population quantity, density and functioning, including area exploitation. The authors stress the fact that in the case of small mammals, associations between coarse woody debris and population features are not universal for all species, since they tend to differ in ecological characteristics. An analysis of the available literature on the matter reveals that the current knowledge of the associations between small mammals and coarse woody debris needs to be broadened and improved. It concerns, in particular, the areas where this type of research has not yet been conducted, including European and Polish forests.

    Opis:
    The aim of the study was to investigate the pattern of daily activity and connections between daily and spatial activity in relation to the forest undergrowth phytocenosis of the two most common rodent species – bank vole Myodes (Clethrionomys) glareolus (Cricetidae) and yellow−necked mouse Apodemus flavicollis (Muridae). The research was carried out in July 2017 in the oak−hornbeam habitat in the Browsk Forest District in the northern part of the Białowieża Forest. For rodents catching and vegetation evaluation the 1 ha study plot was divided into 100 squares of 10×10 m. Catches were made according to the catch−mark−release method. Wooden live traps (with bait and food for caught animals in the form of the grains of cereals, juicy fruits and aromatic fat) were set in the center of each square. The traps were controlled during 4 days at 3−hour intervals (0 a.m., 3 a.m., 6 a.m., 9 a.m., 12 p.m., 3 p.m., 6 p.m. and 9 p.m.). Traps occupied by rodents were marked with colored adhesive cards according to the established code. Twice a day – at 6 a.m. and 6 p.m. caught rodents were identified to the species and released next to the traps. The catch time was recorded. In total, 151 catches were registered. The daily activity of rodents was determined based on the total catches into assumed time intervals and at different times of the day (day, night, dawn/twilight). We provided a detailed description of undergrowth features of the area where rodents were caught. In each square we assessed the dominant species (on this basis the plants communities were established), the average height of vegetation and the degree of soil coverage with plants (undergrowth density). Collected data were used to the interpretation of the spatial activity of rodents in relation to the different undergrowth characteristics. The bank vole was distinguished by an even, day−and−night activity rhythm, while the yellow−necked mouse by monophasic – remarkably nocturnal activity. The dependence of the phytocenosis characteristics and spatial distribution of rodents was revealed for the daily activity of bank vole and twilight−dawn activity of both species. At dawn and dusk voles and mice were active in places with high vegetation. The density of undergrowth was the most important feature for bank voles during the day.

    Opis:
    The paper analyses knowledge of secondary school pupils from Ustrzyki Dolne and tourists visiting the Bieszczady National Park. Both groups were surveyed in 2011−2012. Tourists and pupils were well−informed about the presence of brown bear in the Bieszczady (96%), but far less about its distribution in other mountain ranges. Nearly 30% of the questioned tourists were not aware of the fact that leaving organic leftovers is not allowed in bear habitats and both groups had problems with indicating the actual dangers for the population of brown bear in Poland. The most frequent reported damages caused by bears in Poland such as damages in apiaries were indicated by small number of pupils (6%), while the majority pointed out attacks on human (44%) and damages in households (21%). About 31% of pupils wrongly stated that fishes are often eaten by bears in Poland. Only a few of them (4%) wrote about leftovers as a possible source of food for bears. The research indicates that it is urgent to enhance a knowledge about a distribution of brown bear in Poland and a correct waste management in areas where bears are present.

    Opis:
    Beavers activity i.e. dam building, burrows and canals digging and foraging, radically changes the environment at both abiotic and biotic level. The consequences of beavers activity for other organisms are visible mainly through changes in their habitats. Such changes influence the number, species composition and species diversity of numerous flora and fauna species. One group of species that also may be influenced by beavers activity are small mammals (Rodentia and Soricimorpha). In Bieszczadzki and Magurski National Parks (southern Poland), small mammals community has not been studied at beaver sites yet. The aim of this study was to determine species composition, species diversity, and the relative abundance of small mammals at beaver sites, comparing to sections of the stream not inhabited by beavers (control sites). Small mammals were captured in three types of habitats – meadow, forest and riparian woodlots. Transects with live−traps were set there within beaver and control sites. Captures were conducted from one to three times annually, during 2−3 consecutive years. Total trapping effort amounted to 2540 trapdays. It was found that species composition, species diversity, and also the relative abundance of small mammals did not differ significantly between beaver and control sites. Only M. agrestis had significantly higher share in the community at the beaver sites. In mountain conditions, the presence of beaver sites probably does not affect the communities and abundance of small mammals significantly.

    The paper presents research on the number of large and middle−sized mammal species and changes in their populations (1996−2005) in Polish national parks. The greatest number of native mammalian fauna was found in the Carpathian and the eastern national parks. Clearly the smallest number of mammalian species were recognised in the southern uplands, north−western and especially the Sudety region parks. Non−native species of large mammals, which were almost non−existent in the Carpathian parks, occurred in the remaining regions – primarily in the north−western part of the country. The number of native mammalian species in Polish national parks was positively correlated with longitude and in the mountains − negatively correlated with latitude.

The tree height index permitted to state that cervidas and bisons were the damage−causing agents. Other indices (density, tree height sum and species diversity) were insufficient to assess the effect of wild boars.

    Opis:
    Maintaining biological diversity is one of the main goals of modern forestry. To reach this objective we need to know how management practices affect forest species. This study summarizes the results published in papers on the influence of clear−cutting on small mammals. Most of the studied species increased in abundance on clear−cuts. The response of voles (Microtus agrestis and M. arvalis) was uniformly positive. Mice (Apodemus flavicollis and A. sylvaticus) and shrews (Sorex araneus and S. minutus) varied in their responses but generally their number increased on clear−cuts. Bank voles (Myodes glareolus) appeared to be associated with the heterogeneity of habitat rather than with the age of forest stands per se. Nevertheless, our knowledge on the effects of forest management on small mammals is far from complete. In particular, there are almost no studies on the subject conducted in Western Europe or concerning management practices other than clear−cutting.
