Nutrient intake and its possible drivers in free‐ranging European brown bears (Ursus arctos arctos)
Sign Up to like & getrecommendations! Published in 2023 at "Ecology and Evolution"
DOI: 10.1002/ece3.10156
Abstract: Abstract The dietary nutrient profile has metabolic significance and possibly contributes to species' foraging behavior. The brown bear (Ursus arctos) was used as a model species for which dietary ingredient and nutrient concentrations as well… read more here.

DOI: 10.1002/ece3.4872
Abstract: Abstract The abundance and distribution of large carnivores in Europe have been historically reduced. Their recovery requires multilevel coordination, especially regarding transboundary populations. Here, we apply nuclear and mitochondrial genetic markers to test for admixture… read more here.

DOI: 10.1016/j.biocon.2019.108210
Abstract: Abstract One of the main factors limiting the acceptance of large carnivores is livestock depredation. Reducing damages on livestock requires understanding how depredation varies in space and time. The conservation of the brown bear (Ursus… read more here.

DOI: 10.1016/j.foreco.2021.119471
Abstract: Abstract Active forest management for timber production, through the harvesting of forest stands using cut blocks, frequently overlaps grizzly bear (Ursus arctos) habitat on multi-use landscapes in North America, making it critical to understand how… read more here.

DOI: 10.1038/s41598-019-57126-y
Abstract: During six months of annual hibernation, the brown bear undergoes unique physiological changes to adapt to decreased metabolic rate. We compared cardiac structural and functional measures of hibernating and active bears using comprehensive echocardiography. We… read more here.
