DNA shows where Washington culvert replacements helped spawning salmon

A project led by the UW used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of eDNA in future environmental impact reporting.

A new effort at the University of Washington aims to accelerate eDNA research by supporting existing projects and building a network of practitioners to advance the nascent field.

eDNA a useful tool for early detection of invasive green crab

As the green crab invasion in the state worsens, a new analysis method developed by University of Washington and Washington Sea Grant scientists could help contain future invasions and prevent new outbreaks using water testing and genetic analysis. The results show that the DNA-based technique works as well in detecting the presence of green crabs as setting traps to catch the live animals, which is a more laborious process. Results suggest these two methods could complement each other as approaches to learn where the species’ range is expanding.

Puget Sound eelgrass beds create a ‘halo’ with fewer harmful algae, new method shows

Genetic clues show that eelgrass growing underwater along Puget Sound shorelines is associated with fewer of the single-celled algae that produce harmful toxins in shellfish. The evidence shows this effect extends 45 feet beyond the edge of the eelgrass bed.

What makes influential science? Telling a good story

Researchers from the University of Washington have found that scientific papers written in a more narrative style were more influential among peer-reviewed studies in the climate change literature. Their results were published Dec. 15 in the journal PLOS ONE.

Floating DNA reveals urban shorelines support more animal life

A view of downtown Seattle.

Researchers are now able to capture the cells of animals, sequence their DNA and identify which species were present at a point in time. A new University of Washington study is the first to use these genetic markers to understand the impact urbanization has on the environment — specifically, whether animal diversity flourishes or suffers.

DNA detectives able to ‘count’ thousands of fish using as little as a glass of water

Visitors stand looking through glass as sea animals swim by

A mere glass full of water from a 1.2 million-gallon aquarium tank is all scientists really needed to identify most of the 13,000 fish swimming there.
