Responses of American black bears to spring resources [PDF]

open access: yesEcosphere, 2021
AbstractIn temperate regions of the world, food resources are seasonally limited, which causes some wildlife species to seek out nutrient‐rich resources to better meet their caloric needs. Animals that utilize high‐quality resources may reap fitness benefits as they prepare for mating, migration, or hibernation.
