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

Alaska sockeye salmon.

A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.

Are petite poplars the future of biofuels? UW studies say yes

small poplars

A University of Washington team is trying to make poplar a viable competitor in the biofuels market by testing the production of younger poplar trees that could be harvested more frequently — after only two or three years — instead of the usual 10- to 20-year cycle.


What counts as nature? It all depends

The environment we grow up with informs how we define "nature," UW psychology professor Peter Kahn says. Encounters with truly wild places inspire people to preserve them.

    Think, for a moment, about the last time you were out in nature. Were you in a city park? At a campground? On the beach? In the mountains? Now consider: What was this place like in your parents’ time? Your grandparents’? In many cases, the parks, beaches and campgrounds of today are surrounded…

Climate change challenges the survival of fish across the world

john day river

  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 are the chances for fish to survive as climate change continues to warm waters around the world? University…

Q&A | Sanne Knudsen: Consumers need more protection from chemicals and pesticides

Regulation of chemicals and pesticides effectively leave it to consumers to manage their own risk of exposure, writes Sanne Knudsen, a University of Washington associate professor of law.

  Sanne Knudsen was an undergraduate in Chicago when she got her first close-up look at environmental justice. As an environmental engineering student at Northwestern University, Knudsen answered an attorney’s call for volunteers to study several neighborhoods on Chicago’s South Side, communities that had endured more than their share of pollution and exposure to chemicals….

river flowing through mountain valley

Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet’s temperature over millions of years.
