Full-text available
The gray wolf Canis lupus range in central Europe is dynamically expanding, reconnecting previously isolated populations. Thus, a recent paper has proposed to merge the current Baltic and Central European (CE) wolf management units, which are no longer isolated by distance. However, recent genetic findings indicate that these two populations are no...
Article
Full-text available
Our understanding of animal adaptations to human pressure is limited by the focus on rare taxa, despite that common species are more significant in shaping structure, function and service provision of ecosystems. Thus better understanding of their ecology and beha-vioural adjustments is central for drafting conservation actions. In this study, we u...

Wildlife crossing structures (WCSs) enhance connectivity between habitats of wild animals fragmented by fenced motorways, but factors affecting their use by targeted species remain understudied, particularly in areas recently recolonized by large carnivores. We investigated the use of WCS-6 overpasses (width 30-45m), 5 large underpasses (width 33-1...
Article
Full-text available
In wolves Canis lupus, scent marking plays an important role in territory defence. In Europe, studies on patterns of scent marking in wolves have mostly been conducted in mountains or primeval forests, but since these areas are characterised by low human activity, the impact of people on this behaviour has been neglected. We conducted a study that...

The wolf population has flourished across the whole of Poland since its strict protection in 1998. Wolves are also protected within the national parks and Natura 2000 sites that secure their habitats. Precise data on the status of local populations are required to plan conservation actions. For this reason, we applied camera trapping and non-invasi...
Article
Population fragmentation represents a leitmotif of conservation biology, but the impact of population reconnection is less well studied. The recent recolonization of large carnivores in Europe is a good model for studying this phenomenon. We aim to show novel data regarding distribution and population genetic structure of the grey wolf in Central E...
Article
Monitoring of the wolf Canis lupus is a demanding task as it lives in low densities, utilizes vast home ranges and disperses over large areas. These factors make obtaining accurate data about population parameters over the whole distribution area of the species impossible. Thus detailed local studies on socio-spatial organization are essential to c...
