October 2020 - new paper: "Climate drives the geography of marine consumption by changing predator communities"
We are really happy to share news that a global scale "squidpop" experiment, which PhD Student Ross Whippo helped lead, is now published in PNAS! I am a coauthor as well, for contributing the local OIMB data. But Ross was working on this and co-ordinating this whole effort before he started in my lab, when he was working as a research scientist at the Smithsonian Institution MarineGEO program. Congratulations to a huge team for this effort, and especially Ross, who is the 2nd author on the paper!
My postdoc Dr. Julie Schram and I had a great summer of research working with our 2019 NSF Research Experience for Undergraduates (REU) students (Hannah Hayes and Steven Manos)! We also had a Murdock Trust Fellow working with us again for the 2nd year (Erica Street), and our 2018 REU (Natalie Thompson) is now working in the lab as a technician! This year our projects focused on experiments to quantify the effects of ocean acidification on juvenile Dungeness crab behavior. What a team!

I updated my website with a bunch of new content to highlight more of my recent research and directions!
My collaborator Dr. Alex Lowe and I received support through the SeaDoc Society to do a few submersible dives with OceanGate's Cyclops1 in the San Juan Islands in September 2018! Our research team will focus on observations of deep water red urchins and the drift algae that supports the urchins!
Check out this article in GeekWire about the project.
My first graduate student Zofia Knorek, successfully defended her MS at OIMB! She's already moved on towards her next step, which is a PhD program at UNC!
I'm pleased to announce that we (my postdoc Dr. Julie Schram and I), were recently funded by Oregon Sea Grant to research the effects of ocean acidification on newly settled juvenile Dungeness crab. We'll be investigating crab behavior, predator-prey sensing (i.e., "smell"), and other responses under OA conditions in the lab. Please see the summary on the Sea Grant website for more information. The photo on the left shows a high density of crabs in the age class we will be working on. Photo credit: Reyn Yoshioka.
Thanks to Reyn we now have a lab crest/logo. Somehow it covers all of the bases I hoped for: fatty acids, invertebrates, algae, OIMB; all while looking super cool. Thanks Reyn!

I have a new paper in Ecology in 'The Scientific Naturalist' series, published this May! In this paper we describe an exceptionally high-density juvenile crab recruitment event on the Oregon Coast that we documented last spring. The article (download) links to some additional videos of crabs in nearby areas and documents some really interesting behavior.
We actually know very little about the ecology of juvenile Dungeness crab. The period of time between settlement from the larvae and harvest of mature males in the fishery (usually 4 year old crab) is still largely a mystery, despite the fact that this is one of the most valuable fisheries on the west coast.

I'm happy to announce that Reyn Yoshioka and Zofia Knorek will be joining my lab as graduate students in the Fall of 2016! Our group also includes Julie Schram (postdoc) and Elena Rubio López (visiting grad student from Spain). I'll be updating the 'People' pages soon to feature these exciting collaborators!

Geoducks are large, long-lived bivalves that are an important part of ecosystems and our economy. Wild subtidal populations are harvested using SCUBA, and intertidal aquaculture of these clams is on the rise. I am co-author on two papers (led by P. Sean McDonald, UW) that just came out in the Journal of Shellfish Research special issue on Geoducks. The first paper (McDonald et al. 2015a) uses a combination of SCUBA survey and remote drop camera techniques to estimate geoduck abundance in a Hood Canal, a very large fjord in Puget Sound. The second paper investigates the short-term effects of structures associated with intertidal geoduck aquaculture on other intertidal organisms (McDonald et al. 2015b). Check out the special issue to learn more about geoducks!

My collaborators in Finland and I have a new paper out today in Ecosphere (an open access ESA journal)... Here we asked: What phytoplankton are in the lake? We compared results from a fatty acid mixing model and traditional microscopy. To the right is my 'twitter' version of the paper. Check it out! The link to the paper is here.
I am now working with Prof. Stephanie Hampton (Washington State University) in Pullman, at the School of the Environment. Stephanie is also director for CEREO (the Center for Environmental Research, Education, and Outreach), an exciting interdisciplinary alliance of researchers, at WSU and beyond, who are studying a wide range of environmental issues. We are working on a large collaborative effort to synthesize under-ice biological data from lakes all over the world.
We have a new paper in JEMBE which synthesizes results from a diverse series of student experiments at FHL testing the value to various marine consumers of algal diets in different stages of decay. We found that the value of degrading detritus varies among algae with differing levels of chemical defenses. Check it out on the journal website or my publications page.
I have a few updates on new papers from myself and collaborators; 1) marine particulate organic matter composition and biomarker dynamics (Oikos; Lowe et al. 2014), 2) an analysis of intertidal isopod resource use with a Bayesian fatty acid mixing model (MEPS; Galloway et al. 2014), and (see the figure) 3) effects of diet-degradation on red urchin gonads and biomarkers (MEPS; Raymond et all. in press). There are PDFs of all published manuscripts here.
Also, check out the FASTAR model script and a series of related datasets we used for the published papers on the EcologyBox website:
Our first manuscript using the fatty acid based Bayesian mixing model approch we have been working on the last couple of years is now in press in Freshwater Biology (see publications page for pdf). It offers an interesting perspective on the use of phytoplankton, terrestrial particulate organic matter, and bacteria by cladoceran zooplankton in large lakes in Finland. The analysis shows the critical importance of high quality phytoplankton groups (cryptophytes and diatoms) in supporting basal grazers in these large lakes and offers a novel insights into specific use of of several phytoplankton groups that cannot be otherwise resolved with non source-specific stable isotopes and the few degrees of freedom inherent in in 2-3 variable isotope mixing models. I also presented this work at the Joint Aquatic Sciences Meeting in Portland OR last week.
Great news! Two of the undergraduate researchers who have been working with me over the last few years have been accepted to graduate school and they will both start this fall. Morgan Eisenlord will be working with Drew Harvell at Cornell, and Wendel Raymond will be joining Ginny Eckert at University of Alaska Fairbanks (in Juneau). See the Collaborators page for more about Wendel and Morgan.
Our research on red urchin density and movement in fixed subtidal transects at several sites and seasons in the San Juan Islands was recently published in Marine Ecology. This project was lead by Alex Lowe, who is now a Ph.D. student in the Ruesink Lab (see the Collaborators page). This work followed up other projects in our lab aimed at quantifying the effects of a large flux of macroalgal detritus to deep subtidal habitats. We found that red urchins move very little in this system, presumably because they can 'sit and wait' to catch all the algal detritus they neeed (this is a link to a YouTube video by Tim Dwyer). This sedentary behavior has effects on associated sessile and mobile benthic invertebrate communities. A PDF can be found here. Also see website of collaborator on this work, Ross Whippo (UBC Graduate Student).
My Finland collaborators and I have a new paper out today in Aquatic Microbial Ecology. We investigated fatty acid signatures of a diverse group of microalgae using multivariate statiistics and show that different algal classes have distinctive signatures. In addition, we identify several source specific fatty acid biomarkers for most groups. The manuscript is Free Access and available either here, or by downloading the PDF directly from my publications page.
This month I am transitioning to a new position in Scandinavia! I will be a Visiting Postdoctoral Researcher working with Dr. Monika Winder at Stockholm University. My position is funded through UC Davis from the California Delta Stewardship Council (to PI Winder) to work a study on nutritional quality (e.g., lipids) of zooplankton in the San Francisco Estuary.

I am now working with Dr. Paula Kankaala and her team on a project investigating the contribution of various energy sources (e.g., allochthonous vs. autochthonous carbon) to large lake food webs. The UEF Department of Biology in the north Karelian region of Finland is truly an amazing place to study limnology.

I successfully defended my PhD yesterday to a packed house at Friday Harbor Labs! I am so grateful to my family, committee, collaborators, and friends for their support along the way! My friend and colleague in the Sebens Lab, Kevin Turner, had the foresight to record a video of the defense. I will eventually post a link to this video on the website. In the meantime, if you want to see it email me directly and I'll send you an invitation to the youtube link.
April 25, 2013
My PhD defense is officially scheduled for 8-May, at UW's Friday Harbor Labs! I will do a follow-up seminar at the School of Aquatic and Fishery Sciences at 1:00 pm on 13-May (room 203).
My second chapter was recently accepted and is now officially 'in-press' at Limnology and Oceanography. Look for this in the next couple of months!
March 25, 2013
Today was a good day for the lab; our paper on fatty acid and stable isotope variation at seasonal and spatial scales was officially published today! We are honored to have the feature article in this issue of Marine Ecology Progress Series. You can download the paper by clicking on the PDF [here].

Our lab had a good showing at the Western Society of Naturalists (WSN) meeting in Seaside, CA last month. Morgan, Kate, and Wendel (undergraduate students in our lab) presented posters. Wendel is looking at response of red urchin gonads to differening species and 'freshness' of algal foods. Morgan and Kate presented the early results mentioned in the summer update. Alex, Beth and I all gave talks.
I presented results from a comparison of biomarker signatures of a suite of invertebrate consumers from multiple sites and 2 depths (10-100 m); fatty acids and stable isotopes differed across depths for most consumers studied. More on that soon. Alex summarized our recent research showing interesting links between marine particulate organic matter (POM) composition (phytoplankton/'detritus' community) and biomarker signatures. Beth presented work from her recently completed Master's showing that microbes are an important (but often overlooked) component of food-web modeling.
We met some great people and had many excellent conversations with fellow marine ecologists about the potential benefits (and "issues") of fatty acids and stable isotopes for food web research.

We just wrapped up teaching for the spring quarter. I TA'd Marine Invertebrate Zoology and a Research Apprenticeship program. I am really excited about several of the undergraduate research projects.
In one study we are looking at fatty acid (FA) response to different algal diets in an herbivorous isopod (Eisenlord). So far the isopods are growing well in the lab - analysis of FA will follow soon.
In another study we compared gonad indices (as a condition index) of green urchins from shallow (~10 m) and deep (~100 m) habitats (Kuhleza).
We will encourage both of these students to present these results at upcoming meetings. Stay tuned!
