The study embraced 159 nest boxes placed in three different study plots in the Wielkopolski National Park in western Poland. In the first season, 64% of nest boxes were occupied by four species: great tit Parus major, blue tit Cyanistes caeruleus, Eurasian nuthatch Sitta europaea and European pied flycatcher Ficedula hypoleuca. The dominant species were great and blue tits. Over 80% of broods of great...
Woodpeckers are a very good indicators of forest naturalness. The fact that many species of these birds are in decline in central and western Europe resulted from changes in forest management (e.g. favouring coniferous forest, removal of dead trees). The aim of this research was to evaluate the importance of patches of deciduous species for the occurrence of some specialized woodpeckers in the conditions...

The paper presents an analysis of abundance of the millipedes (Diplopoda) in the Białowieża Forest (eastern Poland) regarding habitat moisture and fertility. Mean individual biomass depends mostly on habitat fertility achieving higher values on eutrophic and moist sites. PCA and RDA confirmed observed pattern of relationship between millipedes abundance and site conditions.
