Drivers of hibernation in the brown bear [PDF]
Frontiers in Zoology, 2016 (Uploaded by Plazi for the Bat Literature Project) Hibernation has been a key area of research for several decades, essentially in small mammals in the laboratory, yet we know very little about what triggers or ends it in the wild. Do climatic factors, an internal biological clock, or physiological processes dominate?

Denning of Brown Bears in Croatia
Bears: Their Biology and Management, 1997 Twentyeight dens of 15 different European brown bears (Ursus arctos) were located, monitored and measured. Ten of them were used by females with cubs, 9 by females without cubs, 5 by males, and 4 by bears of unknown category. Occasionally bears used more than one den in the same winter, i.e. 4 bears used 2 to 5 dens (mean = 3).

The Brown Bear in Bulgaria [PDF]
Oryx, 1962 In the past, the brown bear was found in all the forested mountain regions of Bulgaria. This is known from written and oral evidence, and there are places with names including the word “bear” where no bears have been seen for a long time. The bear conflicted with the interests of man; it did enough damage to agriculture to be condemned as a pest, and ...
