Smaller Female North Atlantic Right Whales Have Fewer Calves: Declining Body Size May Contribute to Low Birth Rates

The declining body size of North Atlantic right whales may have critical consequences for the future of the species. New research shows that smaller females produce fewer calves.

 
Earlier research showed that North Atlantic right whales are declining in size, in part due to frequent entanglements in fishing gear. The new findings suggest that reducing the impacts of such sub-lethal stresses could help the population to grow.
