摘要: Abstract We used Doncaster's test to differentiate home range overlap in use from mutual attraction grizzly bears (Ursus arctos) based on global positioning system (GPS) telemetry data. From a sample of 61 collared bears, 404 pairs GPS locations placed 2 or more ≤500 m each other at about the same time (within 3 hr). these pairs, 68 were significantly positive associations (mutual attraction) which 65% male–female (MF) and 35% sex. Most MF involved adults. Male female had with 1.8 1.2 partners/year, respectively. Associations between males occurred twice as often pre-berry season than berry season, whereas female–female (FF) frequently season. The length same-sex was shorter associations. Fifty-one percent associated once within single year. For associations, mean distance individual...
