An Evolutionarily Young Polar Bear (Ursus maritimus) Endogenous Retrovirus Identified from Next Generation Sequence Data

Viruses, 2015
Transcriptome analysis of polar bear (Ursus maritimus) tissues identified sequences with similarity to Porcine Endogenous Retroviruses (PERV). Based on these sequences, four proviral copies and 15 solo long terminal repeats (LTRs) of a newly described ...

Histological analysis of incremental markings and crown growth characteristics in mandibular first molars of the red fox, Vulpes vulpes (Canidae, Mammalia)

Journal of Anatomy, EarlyView.
This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...

Genetic turnovers and northern survival during the last glacial maximum in European brown bears

Ecology and Evolution, 2019
The current phylogeographic pattern of European brown bears (Ursus arctos) has commonly been explained by postglacial recolonization out of geographically distinct refugia in southern Europe, a pattern well in accordance with the expansion/contraction ...

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).

Transfer of radiocaesium (137Cs) to lynx (Lynx lynx) and brown bear (Ursus arctos) in Chernobyl affected areas in Sweden

In this study, 137Cs activity concentration was measured in 266 lynxes hunted in early spring during the years 2006-2011 in central and northern Sweden and in 161 bears hunted in the end of August until October during the years 2010 and 2011.

Density‐dependent habitat selection in plains bison

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.
