Every other week we share the latest peer-reviewed publications coming from the College of the Environment. Over the past two weeks, nine new articles co-authored by members of the College were added to the Web of Science database. They include articles about microbial community responses, demersal fish, and more. Read on!

Before humans intervened in forest ecosystems, disturbances such as fire, wind storms and diseases wracked segments of the landscape, killing off swathes of trees and providing spaces for regrowth. Today, forest conditions are largely constrained by logging and conservation strategies, but scientists are recognizing the ecological and community benefits of letting a forest behave in more natural patterns. Scientists at the University of Washington and the state Department of Natural Resources intend to test a management approach that mimics natural disturbance patterns and processes across a portion of the Olympic Peninsula, an area known for having the most rainfall in the lower 48 states, high tree-growth rates and old-growth forests, part of which remain today.

Polar bears depend on sea ice for essential tasks like hunting and breeding. As Arctic sea ice disappears due to climate change, bears across the species’ 19 subpopulations are feeling the strain. But even as scientists try to quantify just how much melting sea ice is affecting polar bears, another group that depends on the iconic mammal for subsistence also is at risk of losing an important nutritional and economic resource.

Authors from the University of Washington and Simon Fraser University are the first to look at the effects land-use changes can have on freshwater ecosystems on a national scale. To do this work, they analyzed data on more than 500 fish species taken from 8,100 locations within streams across the U.S.

An unusually warm patch of seawater off the West Coast in late 2014 and 2015, nicknamed “the blob,” had cascading effects up and down the coast. Its sphere of influence was centered on the marine environment but extended to weather on land. A University of Washington Bothell study now shows that this strong offshore pattern also influenced air quality. The climate pattern increased ozone levels above Washington, Oregon, western Utah and northern California, according to a study published Feb.
