Examination of belugahabitat relationships through the use of telemetry and a Geographic Information System
ABSTRACT. The spatial and temporal relationships between belugas (Delphinapterus leucas) and two characteristics of their habitat—bathymetry and ice concentration—were examined. Observed location-habitat correspondence histograms were compared to random location-habitat histograms, using a Kolmogoro...
