A new University of Washington study has found that Chinook salmon seem to use collective navigation and interact socially to help each other find fish ladders at dams.

A new University of Washington and NOAA Fisheries study found that sea lions have the largest negative effect on early-arriving endangered Chinook salmon in the lower Columbia River. The results of this study will publish Oct. 18 in the Journal of Applied Ecology.

The small subpopulation of polar bears in Kane Basin were doing better, on average, in recent years than in the 1990s. The bears are experiencing short-term benefits from thinning and shrinking multiyear sea ice that allows more sunlight to reach the ocean surface, which makes the system more ecologically productive.

A new University of Washington study uses passive data from a fishing technology company to model the movement of anglers and predict where aquatic invasive species may be spreading.

The Pacific Islands Fisheries Science Center is launching a new citizen science project called OceanEYEs and is seeking volunteers to help find Deep 7 bottomfish in underwater videos.

Each year, our students, faculty, and staff win regional, national, and international awards. Please join us in congratulating this year’s group of award winners!

In the Pacific Northwest, eelgrass serves an important function in the ecosystem by binding sediments, storing carbon, and providing essential habitat for Pacific herring, juvenile salmon, and many other species. Concerningly, eelgrass populations are susceptible to human impacts related to water quality changes or direct disturbance. Eelgrass mitigation and restoration strategies often result in plants being transplanted to new locations where eelgrass may already be present. However, these efforts often lack information on the genetic population structure in an ever-changing environment. A team of interdisciplinary researchers at the University of Washington is developing baseline data for native eelgrass to make the first comprehensive geographic map of state eelgrass population structure and describe the relationship between eelgrass population structure, phenotypic diversity, and local adaptation and resistance to environmental stressors.

An international group of scientists has laid out an ambitious global conservation plan for parasites. A related paper led by the University of Washington found that responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.

Deep-sea anglerfishes employ an incredible reproductive strategy. Tiny dwarfed males become permanently attached to relatively gigantic females, fuse their tissues and then establish a common blood circulation. Now scientists have figured out why female anglerfishes so readily accept their male mates. Their findings are published July 30 in Science.

In their most recent book, Sarah Converse (unit leader, USGS Washington Cooperative Fish and Wildlife Research Unit, and UW associate professor in Aquatic and Fishery Sciences and Environmental and Forest Sciences) and her co-editors explore how managers can use a structured decision making approach to aid in solving natural resource problems.
