Saving endangered whales at no cost

... On the basis of these findings and estimations of seasonal whale presence determined by patterns of whale sightings, the authors estimate that, in terms of impact on right whales, each lobster caught in Canada has less than 1% of the impact of each lobster caught in Maine. The authors propose that if Mai...

UBC researchers reveal dwarf aquatic plants' hidden ancestry
