Beluga whale ecology: a concern of freshwater biologists?

SUMMARY. 1. Churchill estuary beluga whales displayed their highest densities in freshwater habitat, suggesting preferential use. 2. Whale densities in freshwater were as high as 350 animals km −2 and represented over one tenth of the estimated Hudson Bay population. 3. Future environmental assessme...

Description
Summary:SUMMARY. 1. Churchill estuary beluga whales displayed their highest densities in freshwater habitat, suggesting preferential use. 2. Whale densities in freshwater were as high as 350 animals km −2 and represented over one tenth of the estimated Hudson Bay population. 3. Future environmental assessments of hydroelectric development in northern Manitoba, Canada, must consider the effects on the beluga whales.
