Abstract Stable isotope analysis of animal tissue samples is increasingly used to study the trophic ecology target species. The isotopic signatures respond type diet, but also environmental conditions their habitat. In case omnivorous, seasonal or opportunistic feeding species, interpretation values more complex, as it largely determined by food selection, either due individual choice because a...

Fecal glucocorticoid metabolite (FGM) analysis is a non-invasive method to monitor animals' welfare in captivity and wild environments. Glucocorticoid also known as cortisol hormone that indicates the level of stress animals humans. This paper reviews use FGM on bears methodologies used study this every species bear. The review was descriptive review. were included are brown bear (Ursus arctos)...

Road networks provide several benefits to human societies; however, they are also one of the major drivers fragmentation and habitat degradation. Their negative effects include wildlife-vehicle collisions which associated with increased barrier effects, restricted gene flow, local extinction risk. Large carnivores, such as brown bear ( Ursus arctos ), vulnerable road mortality while put safety ...
