Population Delineation of Polar Bears Using Satellite Collar Data
To produce reliable estimates of the size or vital rates of a given population, it is important that the boundaries of the population under study are clearly defined. This is particularly critical for large, migratory animals where levels of sustainable harvest are based on these estimates, and wher...

To produce reliable estimates of the size or vital rates of a given population, it is important that the boundaries of the population under study are clearly defined.
