Harbor seal skulls provide clues to Puget Sound’s past food webs
The adage “you are what you eat” generally turns out to be true. Foods we ingest are broken down into amino acids and absorbed into our bodies, leaving trace elements in our bones. In turn, these amino acids can be traced back to their source like a biological receipt, revealing information about the environment. Using this knowledge, researchers are conducting isotope analysis of amino acids in harbor seal skulls to determine the composition of historical marine food webs.

‘By-the-wind sailor’ jellies wash ashore in massive numbers after warmer winters
Thanks to 20 years of observations from thousands of citizen scientists, University of Washington researchers have discovered distinct patterns in the mass strandings of by-the-wind sailor jellies. Specifically, large strandings happened simultaneously from the northwest tip of Washington south to the Mendocino coast in California, and in years when winters were warmer than usual.

The Ecological Society of America (ESA) is honored to announce the Katherine S. McCarter Graduate Student Policy Award (GSPA) 2021 cohort. This award provides graduate students with the opportunity to receive policy and communication training before they meet lawmakers. ESA selected 23 students to receive the award including Julia L. Indivero from the University of Washington School of Aquatic and Fishery Sciences.
Read moreDNA sequencing reveals genetic basis of herring biodiversity
Herring that spawn at different times of the year are genetically distinct from one another, according to a new paper published Feb 24th in the Proceedings of the Royal Society B. The study, led by Eleni Petrou and Lorenz Hauser from the University of Washington School of Aquatic and Fishery Sciences, shows that populations of Pacific herring along the US west coast are genetically structured based on when they spawn and secondarily, where they spawn.

To understand how Puget Sound has changed, we first must understand how it used to be. But unlike most major estuaries in the U.S., long-term monitoring of Puget Sound fish populations did not exist until 1990. Now researchers have discovered an unconventional method to help fill in gaps in the data: old vessel logbooks.

Affiliate faculty Usha Varanasi recently published an article as part of the ICES Journal of Marine Science (ICES JMS) Food for Thought: Luminaries Collection, a curated collection of articles written by distinguished luminaries in the field of Marine Science.
Read moreChelsea Wood featured on podcast “Science Rules! with Bill Nye”
When it comes to things that give us the heebie-jeebies, parasites reign supreme. However, they are a necessary part of our ecosystems. SAFS assistant professor Chelsea Wood joins Bill Nye on his “Science Rules!” podcast to explain what makes parasites so creepy, how to prevent them from killing us, and why she keeps digging around in decades-old cans of salmon.
Read moreIn Brazil, many smaller dams disrupt fish more than large hydropower projects
A new University of Washington paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
Read moreMore management measures lead to healthier fish populations
Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.
