Examining the impact of settler colonialism on Indigenous food systems

Working at the intersection of environmental justice, food sovereignty, and community-based research, Nicole Doran is centering Indigenous perspectives in her work. Nicole’s research for her masters degree, as a member of Mark Scheuerell’s Applied Ecology Lab at SAFS, has involved a deep dive into available literature to examine the impact of settler colonialism on Indigenous food systems.
With this year marking the 50th anniversary of the Boldt Decision, which upheld the rights of members of several Western Washington Indigenous tribes to fish in accordance with terms of treaties signed in the 1850s, discussions around this topic remain deeply relevant.

Looking ahead: what does climate change have in store for Pacific Coast fish?

From Alaska to California, researchers are looking into the impact of climate change on the distribution of fish that live near the seafloor. Focusing on species such as halibut, pollock, sablefish and rockfishes, which have commercial and environmental importance for the Pacific Coast of the US, these fish are impacted in different ways by shifting ocean temperature and oxygen, resulting in a myriad of knock-on effects.

Will the tides change on tidal energy in the US? Quantifying fish encounters with tidal turbines

Diving into the world of marine renewable energy, Jezella Peraza, a masters student at SAFS, has recently published a paper looking into the probabilities of fish-turbine encounters and impact.
Whereas the renewable energy sector utilizing solar and wind energy is booming in the United States, the uptake of tidal energy is off to a slower start. Tidal turbines, placed on the sea floor, generate energy when water moves through a constricted area.

A view from above: using drones for coastal research in California

Newly based at the University of Washington is the Marine Landscape Ecology Lab (MLEL), led by SAFS Professor, Corey Garza. Conducting research along the Californian coast using drones, Corey’s lab is currently working on two projects funded by the California Ocean Protection Council.
In a collaborative effort with UC Santa Cruz, Stanford University, and the Middlebury Institute for International Studies, the team is trying to understand how the interaction between oceanographic conditions and the presence of marine mammals, impacts the presence of great white sharks.

Taking a deeper look: using fish eye lenses to explore invasive fish impacts on native fish communities

Fighting for the little guy. That’s one of the things Jess Diallo, PhD candidate at SAFS, likes about her work. Her research encapsulates this idea as she explores the impact of invasive fish on native fish food webs, based in a tributary to the lower Colorado River.
Part of Julian Olden’s Freshwater Ecology and Conservation Lab, Jess’ fieldwork in 2021 involved collecting samples for stable isotope analysis, including fish eye lenses, to provide a deeper look into how fish move throughout the food web.

Listening closely: using acoustics to study Greenland’s marine mammals

Recently completing her PhD focused on marine mammals in Greenland, Marie Zahn’s work in the Arctic provides a deeper look into two species: narwhals and belugas.
Conducting her research at the School of Aquatic and Fishery Sciences (SAFS) as a member of the Laidre Lab, Marie explored the marine habitat and sounds produced by narwhals and belugas using oceanographic and acoustic data collected from West Greenland.

Salmon, scales, and spectrometry: analyzing historical fish scales to explore food web changes over time

For over 60 years, the Alaska Department of Fish and Game have collected scales from sockeye salmon in Bristol Bay. Now, these scales are receiving special treatment in a new project led by SAFS graduate student Grace Henry, who is conducting stable isotope analysis to examine how food webs in the North Pacific Ocean have changed since the 1960s.
Chemistry has always been Grace’s biggest interest: “I love chemistry, and for me, it’s the cornerstone of ecological science.” Working with stable isotopes in her pre-graduate studies, Grace wanted to use this method during her thesis work on food webs using historical archived samples.
