Identifying presence or absence of grizzly and polar bear cubs from the movements of adult females with machine learning [PDF]
Background Information on reproductive success is crucial to understanding population dynamics but can be difficult to obtain, particularly for species that birth while denning. For grizzly (Ursus arctos) and polar bears (U.
