Importance of resource selection and social behavior to partitioning of hostile space by sympatric canids
Investigations into mechanisms of resource partitioning are particularly suited to systems where nascent interactive behaviors are observable. Wolf (Canis lupus) recolonization of the Greater Yellowstone Ecosystem provided such a system, and we were able to identify behaviors influencing the partiti...

Investigations into mechanisms of resource partitioning are particularly suited to systems where nascent interactive behaviors are observable.
