When to fish: Timing matters for fish that migrate to reproduce

It’s no secret that human activities affect fish, particularly those that must migrate to reproduce. Years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation. A new University of Washington study points to yet another human factor that hampers the ability of fish to reproduce: the timing of our fishing seasons.

Mountain glaciers shrinking across the West

Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each year since 1957 at South Cascade Glacier in Washington state; or tracking glacier area using photographs from airplanes and satellites. We now have a third, much more powerful tool. While he was a doctoral student in University of Washington’s Department of Earth and Space Sciences, David Shean devised new ways to use high-resolution satellite images to track elevation changes for massive ice sheets in Antarctica and Greenland.

Climate change challenges the survival of fish across the world

Climate change will force many amphibians, mammals and birds to move to cooler areas outside their normal ranges, provided they can find space and a clear trajectory among our urban developments and growing cities.  But what chance do fish have to survive as climate change warms up waters around the world? University of Washington researchers are tackling this question in the first analysis of how vulnerable the world’s freshwater and marine fishes are to climate change.

Q&A: How Idaho, Montana, North Dakota and Yellowstone National Park are confronting climate change

The Northern Rocky Mountain ecosystem includes huge swaths of federal lands, two national parks and some of the most spectacular wild spaces in the country. University of Washington researchers are helping managers of those lands prepare for a shifting climate. “Climate Change and Rocky Mountain Ecosystems,” a book published in August, was edited by Jessica Halofsky, a UW research ecologist in the School of Environmental and Forest Sciences, and David Peterson, a senior research biologist with the U.S.
