While it is generally accepted that patterns of intra-specific genetic differentiation are substantially affected by glacial history, population genetic processes occurring during Pleistocene glaciations are still poorly understood. In this study, we address the question of the genetic consequences of Pleistocene glaciations for European grey wolves.(More)

This study on den use by red foxesVulpes vulpes (Linnaeus, 1758) and badgersMeles meles (Linnaeus, 1758) was conducted in central Poland (51°48’N, 19°53’E) over two years. We found a strong negative correlation between monthly den utilisation rate by foxes and air temperature (r=−0.83,p=0.0001). Correlation between temperature and den use by badgers was(More)
Red foxVulpes vulpes (Linnaeus, 1758) are generally regarded as strictly territorial animals, inhabiting distinct and well-separated ranges. The home ranges of these predators can vary in size from a few dozen hectares to as much as 20–30 km2. Because it seemed impossible that foxes could defend areas so different in size with the same intensity, the(More)
Increases in red foxVulpes vulpes (Linnaeus, 1758) numbers and densities have been found in all European countries involved in the rabies vaccination program. In Poland, the number of foxes has increased steadily since the 1990s. Between 1999–2000, the average density of foxes reached 1.3–2 ind./km2 in some parts of the country. The aim of the study was to(More)
