Opis:
Preferences of the Buzzard, Goshawk and Raven in choosing the trees for nesting were studied in northern part of the Augustów Forest (NE Poland) in 2014−2016 years. Study area is dominated by fresh and mixed fresh sites with Scots pine as a dominant species (86% of the forest area). Nests were searched in stands older than 60 years. We found 60 nests of Buzzard, 11 of Goshawk, and 31 of Raven. The diameter and the height of nest trees, the height of nest location, and length of tree crowns were measured. Diameter and height of surrounding trees were also determined. In total, 11 features of nest trees were assessed. For the location their nests, all analysed bird species preferred trees bigger and higher than neighbouring ones. The oldest stands (above 100 years old) were also preferred. The Raven built nests on trees average 139 years old, Goshawk – 119, while Buzzard – 109. Raven nested only on Scots pine, Goshawk on Norway spruce and Scots pine, while Buzzard on silver birch, Scots pine, European larch and Norway spruce. The Buzzard selected for nest trees growing in average distance about 1500 m from forest edge, while Goshawk and Raven preferred nest in a similar distance from the forest edge (707−783 m). Distance of the nests from forest road were similar for Buzzard and Goshawk – about 60 m, and in case Raven it was only 38 m. Raven chose for nesting old−growth islands located on forest edge, or even single old tree growing on plantation. The greatest plasticity in the nest location and habitat diversity was found for Buzzard. Both Goshawk and Raven had more precisely marked habitat and nest preferences.

Opis:
The study was conducted in Lasy Parczewskie forest complex in eastern Poland in two periods: 1991−1993 and 2002−2004. We analysed the location of 384 nests belonging to 6 species of diurnal birds of prey that are common in Poland: Honey Buzzard (Pernis apivorus), White−tailed Eagle (Haliaeetus albicilla), Goshawk (Accipiter gentilis), Sparrowhawk (Accipiter nisus), Buzzard (Buteo buteo), and Lesser Spotted Eagle (Aquila pomarina). We found that all species preferred particular age classes of tree stands (Fig. 2). Sparrowhawk chose tree−stands at age of between 30 and 50 years, Honey Buzzard – older than 50 years, Buzzard and Lesser Spotted Eagle – older than 70 years, Goshawk – older than 80 years, and White−tailed Eagle – older than 90 years. Beside the fact that the Parczew Forests are cultivated and harvested in a common manner, they play an important role for all the species concerned.

Paper presents the results of evaluation of the occurrence and population trends of mammals in 23 Polish national parks. Investigation was based on survey carried out among national park field workers. 29 large and medium−sized mammal species were found in Polish national parks. Growth in the populations of beaver Castor fiber, fox Vulpes vulpes, otter Lutra lutra as well as wild boar Sus scrofa were observed. A clear population regression was recognised for muskrat Ondatra zibethicus and brown hare Lepus europaeus.

Opis:
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.

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.
