Estimating numbers of females with cubs-of-the-year in the Yellowstone grizzly bear population Estimating numbers of females with cubs-of-the-year in the Yellowstone grizzly bear population

For grizzly bears (Ursus arctos horribilis) in the Greater Yellowstone Ecosystem (GYE), minimum population size and allowable numbers of human-caused mortalities have been calculated as a function of the number of unique females with cubs-of-the-year (FCUB) seen during a 3- year period. This approach underestimates the total number of FCUB, thereby biasing estimates of population size...
