Data from: Linking genotype, ecotype, and phenotype in an intensively managed large carnivore
Numerous factors influence fitness of free-ranging animals, yet often these are uncharacterized. We integrated GPS habitat use data and genetic profiling to determine their influence on fitness proxies (mass, length, and body condition) in a threatened population of grizzly bears (Ursus arctos) in A...

Numerous factors influence fitness of free-ranging animals, yet often these are uncharacterized.
