摘要: The goal of habitat selection studies is to identify important habitats for a particular species. However, most using radiotelemetry have focused on habitat-selection patterns daytime positions only. We used 24 h data from six female brown bears (Ursus arctos L., 1758) equipped with GPS-GSM collars and activity loggers analyse var- iations in related diel variations (foraging resting). found that the rested mainly during daylight hours foraged crepuscular nocturnal hours. selected habi- tats differently when they were resting than foraging. no tall coniferous forest us- ing all data, but this was by avoided foraging bears. Thus, selection, our results show importance obtaining dividing these into relevant categories based pattern studied Resume ´ : Le des etudes de d'habitats est d'identifier les qui ont l'importance pour une espece particuliere.
