Algal community composition and food web relationships on the Western Antarctic Peninsula
This NSF-funded project started in the spring of 2019 with a scuba diving research expedition on the Laurence M. Gould. We surveyed the shallow subtidal and collected seaweeds and invertebrates for food web analysis with fatty acid tracers. Photo: Julie Schram.
Effects of ocean acidification and food quality on the post-recruitment ecology of juvenile Dungeness crabs
An Oregon Sea Grant funded project investigating crab behavior, predator-prey sensing, and the consequences of ocean acidification on juvenile Dungeness crabs. What's at stake is the conservation of Oregon's most important commercial fishery. In collaboration with co-PI Dr. Julie Schram. Photo: Reyn Yoshioka.
Marine benthic invertebrate lipid metabolism
I am working on several projects, using an assortment of focal model organisms (urchins, isopods, crabs, gastropods), aimed at understanding the lipid metabolism and trophic transfer of dietary fatty acids to the tissues of invertebrates. How are 'trophic tracers' transferred to basal consumers? How does food quality and environment influence these processes? Photo: Reyn Yoshioka.
Kelp forest ecology, conservation, and detrital subsidies
Kelp forests create food and critical habitat, but these dynamic ecosystems are in decline in many parts of the NE Pacific. I'm working in SE Alaska, British Columbia, the San Juan Islands, and SW Oregon to study how kelp forests act as a trophic resource for herbivores such as urchins and abalone.
