The effect of vehicle noise on farmland birds living in the vicinity of very busy roads was investigated. The study was conducted on two plots of crop fields located near national roads Nr. 12 and 19, the most important trunk roads in Poland and the eastern part of the Europe. The results of the current study are of wide relevance because crop fiel...

Of all forest environments, urban and peri-urban woodlands are beginning to play an increasingly important role in some European countries. Human pressure in suburban forests all across Poland and Europe has been increasing in recent years. During the recent pandemic, people became increasingly aware of the need to be in contact with nature, and ou...

sylwan 166 (8): 524−536, August 2022 https://doi.org/10.26202/sylwan.2022053 Journal homepage: https://sylwan−journal.pl Railway lines act in different, often opposing, ways on the fauna and flora occupying the habi− tats adjacent to them. The expansion of rail infrastructure destroys the natural habitats in the land designated for that purpose. Fo...

Several types of rare behaviour patterns occurring during the post-fledging period were observed in young Marsh Harriers (Circus aeruginosus L.; Aves, Accipitridae). The studies were carried out in natural and anthropogenic habitats in Eastern Poland. Out of 23 monitored nests, 17 individually wing-tagged fledglings from 6 broods were observed duri...

Antimicrobial resistance (AMR) is one of the most important global health concerns; therefore, the identification of AMR reservoirs and vectors is essential. Attention should be paid to the recognition of potential hazards associated with wildlife as this field still seems to be incompletely explored. In this context, the role of free-living birds...

Research results on the impact of railway noise on birds show a variety of bird responses. These behaviours are often different from those exhibited by birds occupying habitats along tarred roads. Knowledge of this subject is still incomplete. We attempted to define the influence of a heavily transited railway line on bird communities at stopover s...

The construction of new railway routes and the modernisation of existing ones usually have an adverse effect on the natural environment in the vicinity of such transport corridors. Negative effects of the construction of the railway line can be observed even at a considerable distance. The high frequency of wildlife-train-collisions (wtc) can lead...

Anthropogenic noise, a consequence of expanding infrastructure and industry in ecosystems, is a serious and ubiquitous threat, which can significantly modify the behaviour and certain population parameters in animals. Birds are particularly vulnerable in this respect, given that they communicate mostly vocally in dense habitats. In the winter time...

Over a period of almost twenty years, clutch size and breeding success in the Montagu's Harrier were investigated in the context of changing environmental conditions in the species' natural breeding habitats in eastern Poland. During the study periods (1990-95 and 2003-12) a decline was noted in the number of breeding pairs in the population nestin...

The construction of railway lines usually has a negative effect on the natural environment: habitats are destroyed, collisions with trains cause deaths, and the noise and vibrations associated with rail traffic disturb the lives of animals. Cases are known, however, where the opposite holds true: a railway line has a positive effect on the fauna in...

We investigated whether high-intensity road traffic affects the nestbox occupancy pattern of secondary hole-nesting birds. Field studies were carried out in two forests in south-eastern Poland (Lasy Janowskie forest and Polichna forest). Both complexes were included in NATURA 2000 network. In our knowledge it was first field experiment on road-traf...

Streszczenie: Szybki rozwój sieci drogowej oraz infrastruktury z nią związanej wywiera silną presję na środowisko oraz żywe organizmy, wykorzystujące siedliska zlokalizowane w pobliżu dróg. Negatywne skutki tego procesu polegają na utracie i fragmentacji siedlisk użytkowanych przez zwierzęta. Osobnym zagadnieniem jest wzrost zanieczyszczeń powietrz...

The very rapid development of the road infrastructure in recent years has adversely affected the natural environment. The main effects of this have been the loss or deteriorating quality of habitats, the mortality of animals due to collisions with road vehicles, the withdrawal of birds as a result of disturbance and excessive noise in the neighbour...

Nest site selection of the ground-nesting Montagu's Harrier was studied in a natural habitat in eastern Poland, the Chełm Calcareous Marshes (850 ha). All nests in the study area were placed in the sedge community Cladietum marisci.

Mate choice is one of the more interesting parts of the life cycle in many species of animals. Different species have quite different signals of honest advertising at the time of pair formation. The chief object is the transfer of information about individual quality. Therefore this behaviour, or phenotypic cues, must be difficult to fake. The Mont...
