The dilemma of female mate selection in the brown bear, a species with sexually selected infanticide
International audience Because of differential investment in gametes between sexes, females tend to be the more selective sex. Based on this concept, we investigate mate selection in a large carnivore: the brown bear (Ursus arctos).We hypothesize that, in this species with sexually selected infantic...

International audience Because of differential investment in gametes between sexes, females tend to be the more selective sex.
