A rising tide of marine disease? How parasites respond to a warming world

Warming events are increasing in magnitude and severity, threatening many ecosystems worldwide. As the global temperatures continue to climb, it also raises uncertainties as to the relationship, prevalence, and spread of parasites and disease. A recent study from the University of Washington explores the ways parasitism will respond to climate change, providing researchers new insights into disease transmission.

SAFS researchers and graduates coauthor international letter addressing transboundary mining pollution

A number of UW researchers have joined an international group of science and policy experts to publish a joint commentary in the journal Science, calling on U.S. and Canadian leaders to address damages and risks caused by Canadian mine pollution flowing downstream into U.S. states. Led by researchers at the University of Montana, the cohort included five graduates and one PhD candidate from the UW School of Aquatic and Fishery Sciences

Pacific oysters in the Salish Sea may not contain as many microplastics as previously thought

In a recent interdisciplinary study, University of Washington researchers at the School of Aquatic and Fishery Sciences, Department of Chemistry and Department of Materials Science and Engineering used advanced methodologies to accurately identify and catalog microplastics in Pacific oysters from the Salish Sea. They have discovered that the abundance of tiny microplastic contaminants in these oysters is much lower than previously thought. The findings were published in January in the journal Science of the Total Environment.

Sockeye salmon fuel a win-win for bears and people in Alaska’s Bristol Bay

In a world where valuable natural resources can be scarce, nature often loses when humans set their sights on something they want. But a new study published in the journal Ecological Applications shows that doesn’t always have to be true. Researchers found that with proper management of salmon fisheries, both humans and bears — who depend on a healthy supply of the fatty, oily fish — can thrive.

Inbreeding and management in captive populations

school of salmon underwater

Pacific salmon hatcheries aim to supplement declining wild populations and support commercial and recreational fisheries. However, there are also risks associated with hatcheries because the captive and wild environments are inherently different. It is important to understand these risks in order to maximize the success of hatcheries. Inbreeding, which occurs when related individuals interbreed, is one risk that may inadvertently be higher in hatcheries due to space limitations and other factors.
