Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,
