    Opis:
    Modern research methods provide many new possibilities to reconstruct the history of species and the colonization of land after its release from the Pleistocene ice sheet. New laboratory techniques and research trends form another, new and interdisciplinary approach to these issues. In this paper, we present the history of plant and animal species during the last glaciation (Vistulian, 115−11.7 ka BP) and after the melting of the ice sheets. We also summarize the evolution of theories and views on this subject. Initially, the role of glacial refugia that are the places of survival of the species and the source of expansion to the north of the continent after the release of Europe from the ice sheet, were attributed to the Iberian, Apennine and Balkan peninsulas. This was due to the fact that in Europe only in these regions favourable conditions for the survival of temperate species existed. However, numerous paleozoological, palaeobotanical and paleoclimatological fossil evidences from the Vistulian period, and extensive molecular research on contemporary populations of species inhabiting different areas of the continent show a completely different image of glacial refugia and another model of postglacial expansion. The paper describes documented significance of extensive refugia (macrorefugia) that existed in the Carpathians, the Crimea, the Ural, the Caucasus and the Russian Plain in postglacial colonization of Europe. It shows also importance of small northern refugia often found near the border of the ice−sheet in survival of boreal species. One of the nearest refugium in the vicinity of the border of the ice sheet in last glacial maximum period was the refugium located in the Kraków−Częstochowa Upland (S Poland) and in the Świętokrzyskie Mountains (C Poland).

    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.
