The article overviews the role of bats in the forest ecosystem (especially the European forest), the impact of environmental pollution on the forest and bats, and the issue of bats indication of the forest environment condition. Existing data on the transfer of pollutants to the environment and between the aquatic and terrestrial environment are reviewed. The water environment is an important receiver...
The objective of the study was to recognise the species composition of bats in two forest stands that differ in terms of habitat type and age class. The study was carried out in the Niepołomicka Forest (southern Poland). An ultrasound ‘time−expansion’ processing system with Pettersson D240× detector was used to identify bat species by their echolocation signals employing SonoBat v.2.9.7 software to...
The vegetation of allotment gardens is an important element of urban green areas and constitutes a habitat where many groups of insects exist, including aphids. This research involved the monitoring of winged morphs of aphids in allotment gardens in the area of Poznań with the use of Moericke traps. The fauna structure of aphids in two large allotment gardens was demonstrated by comparing the activity...
One of the greatest challenges of nature conservation is to identify and locate networks of pro tected areas, which will preserve the biodiversity. The paper aims to show the ornithological value of the Sobibór Forests (E Poland) and to emphasize the fact that the network of Important Bird Areas (IBA) and Special Protection Areas within Natura 2000 (SPA) may require additions. The study was conducted...
The Black Woodpecker Dryocopus martius excavates nesting holes in big trees and use dead wood for foraging. It is considered as a key and an indicator species in the protection of biodiversity of forest ecosystems, because its cavities condition the possibility of breeding the biggest secondary cavity−nesters, bats, and some species of wasps. We studied preferences of the Black Woodpecker towards...
The paper synthesizes the knowledge on the impact of silvicultural treatments on bat populations. Forest management affects stand structure and composition, and silvicultural treatments exert both positive or negative impact on the activity of individual bat species. Studies published on the issue suggest that forest management may prove useful for the conservation of bat populations, especially in...
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...
