Although eelgrass populations have declined in some parts of Puget Sound, overall numbers for the aquatic plant have remained steady ecosystem-wide, according to an analysis of 41 years of data from the Washington Department of Fish and Wildlife. The study, published in the Journal of Ecology, was co-authored by Puget Sound Institute lead ecosystem ecologist Tessa […]

Year in review: 2016
This year has been as busy as any we have had since our founding in 2010. As we look forward to year seven (!) of our organization, we have put together a sort of highlight reel of accomplishments. At various points, PSI scientists worked to prioritize emerging contaminants in our waterways. We studied the health of […]

A comparative study of human well-being indicators across three Puget Sound regions
Puget Sound Institute social scientist Kelly Biedenweg has published a comparative study of three well-being indicators in the Puget Sound region. The article appears in the August issue of the journal Society & Natural Resources. Abstract: Simple frameworks that generalize the best metrics of human well- being related to the natural environment have rarely been empirically […]

Paper looks at social–ecological approaches to herring management
A new paper co-authored by PSI’s Tessa Francis connects social and ecological factors influencing herring management in the Salish Sea. The paper, published in the journal Ecosystem Health and Sustainability, grew out of a three-day workshop held last year in British Columbia. The workshop was sponsored by The Ocean Modeling Forum, a collaboration between the School of Aquatic […]

Herring fishery’s strength is in the sum of its parts, study finds
The online publication UW Today reports on a recent paper co-authored by PSI research scientist Tessa Francis. The paper, published in the journal Ocealogia, describes how individual herring populations in Puget Sound exhibit a portfolio effect, collectively influencing and stabilizing the region’s population as a whole. Francis teamed up with the paper’s lead author UW doctoral student Margaret […]

New papers look at ‘zombie’ steroids
They are sometimes called ‘zombie’ chemicals. Some compounds thought to be safe and inactive can change into dangerously active forms when they are exposed to the environment. Two recent papers co-authored by PSI collaborator Ed Kolodziej look at some of the ways that regulators may need to account for these transformations. Cole, EA, McBride, SA, Kimbrough, KC, Lee, J, Marchand, […]

Assessing microplastics in the world’s oceans
Our Director Joel Baker recently co-authored Microplastics in the Ocean: A Global Assessment, an international report commissioned by GESAMP (The Joint Group of Experts on Scientific Aspects of Marine Environmental Protection). GESAMP is an inter-Agency Body of the United Nations, comprised of a group of independent scientists providing advice to UN Agencies on a wide variety of […]

Impacts of diving ducks on herring populations
Puget Sound Institute Lead Ecologist Tessa Francis attended the 2015 meeting of the International Congress for Conservation Biology earlier this month in Montpellier, France. She presented results from her recent work with colleagues at NOAA’s Northwest Fisheries Science Center evaluating the impacts on Puget Sound herring populations of herring egg predation by seabirds and other predators. […]

Is there a shift in the Puget Sound food web?
A Seattle Times story features a recent paper in the Marine Ecology Press Series about shifting baselines in the Puget Sound food web. Forty years of data from the Washington Department of Fish and Wildlife reveal a trend toward more jellyfish and less of some forage fish species in the region. High amounts of jellyfish can […]

Paper says spawning herring show little preference for vegetation
Pacific herring are known to lay their eggs on a wide variety of submerged vegetation, from algae to seagrass. A new study in the Marine Ecology Progress Series reports that Puget Sound herring show little preference when it comes to these types of spawning vegetation. The paper, co-authored by Puget Sound Institute Lead Ecologist Tessa Francis, analyzes […]
