In a new study, 天美影视传媒 researchers collected salmon DNA in air filters near a stream, showing that eDNA can move between air and water, a possibility scientists hadn鈥檛 accounted for that opens new avenues for monitoring aquatic species.

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 天美影视传媒 aims to accelerate eDNA research by supporting existing projects and building a network of practitioners to advance the nascent field.
As the green crab invasion in the state worsens, a new analysis method developed by 天美影视传媒 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鈥� range is expanding.
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.
Researchers from the 天美影视传媒 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.
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 天美影视传媒 study is the first to use these genetic markers to understand the impact urbanization has on the environment 鈥� specifically, whether animal diversity flourishes or suffers.
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.
