摘要: A breeding male Gray Wolf, Canis lupus , equipped with a GPS collar was documented going to the den site of another Wolf pack. This trip coincident an attack on other pack and occurrence dead partially consumed pup at same location. We present two possible explanations - interspecific predation non-parental infanticide account for this observation. Because his mate were first-time breeders attempting establish territory space their own, we speculate that, based available evidence, observation most likely represents case that fits predictions resource competition hypothesis.
