Nearly One-Tenth of Hemisphere’s Mammals Unlikely to Outrun Climate Change

A safe haven could be out of reach for 9 percent of the Western Hemisphere’s mammals, and as much as 40 percent in certain regions, because the animals just won’t move swiftly enough to outpace climate change.

For the past decade scientists have outlined new areas suitable for mammals likely to be displaced as climate change first makes their current habitat inhospitable, then unlivable. For the first time a new study considers whether mammals will actually be able to move to those new areas before they are overrun by climate change. Carrie Schloss, University of Washington research analyst in environmental and forest sciences, is lead author of the paper out online the week of May 14 in the Proceedings of the National Academy of Sciences.

Decades of wild swings in crab populations – some natural, some human-caused – dramatize the myriad issues surrounding questions about sustainable fisheries and the ecosystems that support them.

So said David Armstrong, professor and director of aquatic and fishery sciences, in his Jan. 5 talk “Claws, causes, climate and corps: A cavalcade of true crab sagas.” (more…)

Satellite Tracking Helps Russian Tanker Navigate Critical Sea Duck Habitat

ANCHORAGE — On its way to deliver emergency fuel to Nome, Alaska, the Russian tanker Renda will move through an area used by wintering spectacled eiders, a federally threatened sea duck. But, to protect the ducks and their wintering habitat, resource managers from the U.S. Fish and Wildlife Service and navigators from the U.S. Coast Guard are using satellite telemetry information from the U.S. Geological Survey to plot a route for the tanker that minimizes impacts to this species and its habitat.

“Nearly 20 years ago, USGS biologists used the latest satellite tracking technology available at the time to uncover the mysterious wintering behavior of the spectacled eider, now a threatened species,” said USGS Director Marcia McNutt. “Little did these scientists know at the time that their information would be critical in allowing a Russian tanker decades later to thread the needle to Nome in order to deliver life-saving fuel oil without taking a toll on these elusive sea ducks.” (more…)
