Earlier studies have indicated that consumption of beavers Castor ssp. by wolves Canis lupus varies seasonally and is influenced by rainfall affecting water levels. Therefore, to determine whether these carnivores prey more often on beavers in drier seasons and years, we assessed the diet of wolves in Wigry National Park (NE Poland) by analysing 30...

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...

Our goal was to asses importance of beaver Castor fi ber in the wolf Canis lupus diet in the Wigry National Park (WNP), NW Poland. We compiled published data and results of own analyses of wolf scats collected in 2017-2018. We found that in WNP wolves prey mainly on wild ungulates, but beaver was an important additional prey accounting for 10.9% an...

During intense monitoring with camera traps (45069 trap-days) conducted in Wigry National Park (northeastern Poland) in 2013-2018, we confirmed presence of the Eurasian lynx Lynx lynx only in March 2015 – most likely single individual. Thus we conclude that lynx occurs in that national park only sporadically.

The diet of wolves Canis lupus L. was assessed in the Wigry National Park in North-Eastern Poland, which overlaps with the Natura 2000 site "Ostoja Wigierska". The content of a total of 149 scat samples was collected in 2017 and analysed in order to determine dietary composition. Wolves primarily feed on wild ungulates, which make up 75.4% of food...

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...

... According to the last factor, it was assumed that disturbances in rainfall may cause the water level in watercourses to lower, and thus limit the habitat conditions for beavers. In addition, lower water levels make it difficult for beavers to hide from wolves, as a result, predators have easier hunting and increase the proportion of beavers in their diet (Mysłajek et al., 2021). A similar model was built for Belarus (Model BY ), in addition to the independent variables of precipitation, wolf density, and beaver density, the percentage of the beaver population harvested by hunters was added. ...
... Several wolf management units -so-called Baltic, Central European and Carpathian subpopulationswere identified in Central Europe based mainly on species distribution, landscape features, suitability of habitats, dispersal abilities and differences in population management (Linnell et al. 2008, Boitani 2018. Recently, this differentiation has also been supported by studies on the genetic structure of the wolf population (Szewczyk et al. 2019(Szewczyk et al. , 2021b. Moreover, genetic studies indicated that in southeastern Poland, between Baltic and Carpathian subpopulations, there is a cline of genetically distinct wolf subgroups (Pilot et al. 2006, Czarnomska et al. 2013, Szewczyk et al. 2019) extending eastwards roughly along the Belarussian-Ukrainian borderland (Pilot et al. 2006). ...
... (+) Contribution to diet < 0.05%. Data from 2017 after Mysłajek et al. (2018), for 2018 after Mysłajek et al. (2019a, updated), and for 2019 this study. Wolves hunt beavers opportunistically by accidently encountering them within their territories or purposely by waiting near places frequently used by beavers (Gable et al. 2016(Gable et al. , 2018aGable & Windels 2018). ...
... Obecne badania wskazały, że teren Roztoczańskiego Parku Narodowego wykorzystywany jest na stałe przez dwie grupy rodzinne wilków. Obserwowana w RPN liczebność wilczych grup rodzinnych (4-7 osobników) mieści się w zakresie wykazywanym w innych rejonach Polski (Jędrzejewski et al. 2002, Nowak et al. 2008, Nowak i Mysłajek 2016, Romański et al. 2018. ...
