Home range and habitat analysis using dynamic time geography
Wildlife home ranges continue to be a common spatial unit for modeling animal habitat selection. Telemetry data are increasing in spatial and temporal detail and new methods are being developed to incorporate fine resolution data into home range delineation. We extended a previously developed home r...

Wildlife home ranges continue to be a common spatial unit for modeling animal habitat selection.
