Very Small Home Ranges of Two Gravid European Brown Bears during Hyperphagia
In September 2019, two gravid female brown bears ( Ursus arctos ) were captured and equipped with GPS/GSM collars in Paklenica National Park (Croatia). Home ranges during hyperphagia were analyzed to describe the spatiotemporal requirements. Mean seasonal home ranges were very small with 9.2 km 2 an...

In September 2019, two gravid female brown bears ( Ursus arctos ) were captured and equipped with GPS/GSM collars in Paklenica National Park (Croatia).

During the tracking period, both bears used different territories and showed little to no use of overlapping area.
