From the Washington Post:

Ransom A. Myers, 54, the world-renowned fisheries biologist whose research showed that the number of large fish in the world’s oceans has dropped by 90 percent in the past 50 years, died of a brain tumor March 27 at a hospital in Halifax, Nova Scotia.

The journal Science has just published a major paper co-written by Dr. Myers, “Cascading Effects of the Loss of Apex Predatory Sharks from a Coastal Ocean,” about the importance of sharks in marine ecosystems. There is an abstract of the paper on the Science website.

More than any other scientist, Ransom’s work has alerted us to the full extent of the rapid decline in fish populations in recent years, particularly large pelagics and other predators.
