Data from: Heart rate during hyperphagia differs between two bear species
Hyperphagia is a critical part of the yearly cycle of bears when they gain fat reserves before entering hibernation. We used heart rate as a proxy to compare the metabolic rate between the Asian black bear (Ursus thibetanus) in Japan and the Eurasian brown bear (Ursus arctos) in Sweden from summer i...

Hyperphagia is a critical part of the yearly cycle of bears when they gain fat reserves before entering hibernation.
