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: 10.1002/ece3.5172
Abstract: Abstract 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 model.… read more here.

DOI: 10.1002/ece3.8267
Abstract: Abstract Most animals concentrate their movement into certain hours of the day depending on drivers such as photoperiod, ambient temperature, inter‐ or intraspecific competition, and predation risk. The main activity periods of many mammal species,… read more here.

How absolute biomass intake can alter nutrient profile interpretation in free‐ranging species: the case of protein intake in brown bears
Sign Up to like & getrecommendations! Published in 2025 at "Wildlife Biology"
DOI: 10.1002/wlb3.01458
Abstract: If an animal eats a large amount of a diet of a low content of a macronutrient, it can still ingest a considerable amount of that macronutrient. Various animals have been shown to balance nutrient… read more here.

DOI: 10.1007/s10661-024-13253-2
Abstract: In Nepal, the distributions of three bear species vary: sloth bears (Melursus ursinus) in the lowlands, Asiatic black bears (Ursus thibetanus) in the mid-hills, and brown bears (Ursus arctos) in the high Himalayas. We utilized… read more here.
