Grzegorz Maciorowski, Auteur ; Jan Maciorowski, Auteur ; Piotr Tryjanowski, Auteur ; Artur Golawski, Auteur ; Michał Polakowski, AuteurRe-nesting within the same breeding season after clutch loss is very rarely observed in large raptors, including the endangered greater Spotted Eagle (Clanga clanga). Here, we describe the first well-documented and confirmed case of clutch repla[...]Nouveauté

Patrycja K. Woszczyło, Auteur ; Peter Mikula, Auteur ; Łukasz Jankowiak, Auteur ; Anna Ondrejková, Auteur ; Piotr Tryjanowski, AuteurThe COVID-19 pandemic, which significantly altered human activities, particularly in urban areas, presented a unique opportunity to explore the dynamics of wildlife–human coexistence.

Piotr Tryjanowski, Auteur ; Łukasz Jankowiak, Auteur ; Łukasz Myczko, Auteur ; Peter Mikula, Auteur ; Andrzej Łuczak, AuteurWhite storks (Ciconia ciconia), an emblematic bird of high conservation interest, build massive nests which are also important breeding sites for other birds. However, their role as a potential source of food for foraging birds and bats is unexp[...]
Article
Adam Zbyryt, Auteur ; Łukasz Jankowiak, Auteur ; Leszek Jerzak, Auteur ; Piotr Tryjanowski, AuteurIncubation behaviour is essential for understanding the reproductive success in birds. For example, the orientation of the bird is important for reducing incubation costs associated with wind or sun, but on the other hand can be modified by the [...]

Peter Mikula, Auteur ; Martin Hromada, Auteur ; Piotr Tryjanowski, AuteurBats (Chiroptera) and Common Swifts (Apus apus) are excellent fliers that use buildings as roosts and breeding sites in urban areas. Some predators have recently become adapted to hunting formerly unavailable prey. One such urban predator is the[...]

Piotr Skorka, Auteur ; Magdalena Lenda, Auteur ; Dawid Moron, Auteur ; Rafal Martyka, Auteur ; Piotr Tryjanowski, Auteur ; William J. Sutherland, AuteurCollisions with cars are an important mortality factor for many wild animals. Measures to mitigate road mortality are costly so should be implemented using cost-effective measures in locations where the road mortality is consistently highest and[...]

Aviad Horev, Auteur ; Reuven Yosef, Auteur ; Piotr Tryjanowski, Auteur ; Ofer Ovadia, AuteurPoaching of tigers (Panthera tigris) and its prey base are considered important factors influencing wild tiger populations in India. At present, wild tigers are disappearing even from protected Tiger Reserves. Previous models, designed to unders[...]

Federico Morelli, Auteur ; Frédéric Jiguet, Auteur ; Jiri Reif, Auteur ; Sofia Plexida, Auteur ; Andrea Suzzi Valli, Auteur ; Piotr Indykiewicz, Auteur ; Petra Šímová, Auteur ; Muriel Tichit, Auteur ; Marco Moretti, Auteur ; Piotr Tryjanowski, AuteurThe use of biodiversity surrogates is an increasingly popular tool, because it provides strong results while reducing the costs of conservation studies. Here, we hypothesize that cuckoo (Cuculus canorus) occurrence may correlate with high bird s[...]
Article
Piotr Tryjanowski, Auteur ; Artur Golawski, Auteur ; Stanislaw Kuzniak, Auteur ; Tornasz Mokwa, Auteur ; Marcin Antczak, AuteurNesting in the same breeding area in successive years provides information to help understand the cues used by birds in habitat selection. Moreover, such information may also be an important tool for the conservation and management of endangered[...]

Lukasz Jankowiak, Auteur ; Marcin Antczak, Auteur ; Zbigniew Kwiecinski, Auteur ; Pawel Szymanski, Auteur ; Marcin Tobolka, Auteur ; Piotr Tryjanowski, AuteurThe raptor community wintering in an extensively managed farmland was studied in Western Poland during seven winters (2006-2013). Data on raptor presence and numbers was obtained using the point count method. In the present paper we focus on the[...]

Sparks, Auteur ; Marcin Bocheński, Auteur ; Miroslawa Dabert, Auteur ; Mariusz Kasprzak, Auteur ; Piotr Kaminski, Auteur ; Slawomir Mroczkowski, Auteur ; Ewa Wisniewska, Auteur ; Leszek Jerzak, AuteurSex allocation has been a fertile topic in the development of evolutionary theory. The dominant models for vertebrates have provided predictions of sex ratios based on asymmetry in breeding success between sexes and the relative effect of local [...]

Marcin Tobolka, Auteur ; Tim H. Sparks, Auteur ; Piotr Tryjanowski, AuteurThe White Stork (Ciconia ciconia) is an icon of nature protection and one of the easiest birds to monitor, particularly in Central Europe. Here avian biodiversity was compared between sites (territories) occupied by nesting White Storks and site[...]
Article
Piotr Skorka, Auteur ; Magdalena Lenda, Auteur ; Dawid Moron, Auteur ; Konrad Kalarus, Auteur ; Piotr Tryjanowski, AuteurLittle is known of the impact of roads on insect mortality. This is a significant gap, because road verges are regarded as an important tool for insect conservation. In this study, we investigated which factors affect the number of roadkills in [...]
Article
Piotr Tryjanowski, AuteurSkylarks are morphologically well adapted for endurance-type flight song which mainly serves the marking of territory. The study analyzes the temporal and spatial distribution of non-aerial ("ground") song (on the ground and on perches) in an ag[...]

Populations of plants and animals typically fluctuate because of the combined effects of density-dependent and density-independent processes. The study of these processes is complicated by the fact that population sizes are typically not kn[...]

Magdalena Lenda, Auteur ; Piotr Skorka, Auteur ; Dawid Moron, Auteur ; Zuzanna M. Rosin, Auteur ; Piotr Tryjanowski, AuteurConservation biology often relies on the protection of (semi)natural habitat remnants. However, the ever increasing human population is taking over natural resources and habitats. Here, contrary to most other studies, we ask how human-associated[...]
Article
Piotr Skorka, Auteur ; Magdalena Lenda, Auteur ; Piotr Tryjanowski, AuteurInvasive alien plants constitute a major threat to local biodiversity. Moreover, their appearance often coincides with land use change. Many endangered groups of organisms suffer from habitat loss, which is often a consequence of the invasion of[...]
