The Conversation / UW News Workshops in May

The UW News office, together with editors at The Conversation, is hosting workshops for UW-affiliated faculty, postdocs, graduate students and other researchers interested in writing analysis pieces for mainstream audiences. This is the fourth year the University of Washington has offered these sessions, and the first in an all-virtual format.

Each hour-long workshop will be led by an editor at The Conversation, a news analysis website that publishes articles on timely issues written by academics who draw upon their expertise and research. In 2020, UW researchers across many academic disciplines published 54 analysis pieces and reached more than 1.5 million readers through The Conversation, which makes its published pieces available to other publishers for free, including The Washington Post, The Atlantic, Salon, and many others.

While each workshop will be led by an editor of a different section of The Conversation, the topic is not a prerequisite for attending; sign up for a session that best fits your expertise, or just your schedule. UW News public information officers will attend each session.

Here’s the lineup:

  • Tuesday, May 4, 8:30 to 9:30 a.m.: Science & Technology
  • Thursday, May 6, 9:30 to 10:30 a.m.: Energy & Environment
  • Wednesday, May 12, 10:30 to 11:30 a.m.: Health
  • Friday, May 14, 10:30 to 11:30 a.m.: Politics & Society

Each session will be limited to 10 researchers. Come with questions or even possible ideas you wish to write about. The workshops will include time to engage with the editor and your UW colleagues.

More information, and a link to register, is here. If you can’t make any of these sessions, or they are full, sign up for the waitlist via the registration page and you’ll get notified if a spot opens up.

Only navigable four months of the year due to sea ice, the Chukchi Sea in the Arctic Ocean is one of the more challenging places on the planet to conduct research. The extreme environment has limited exploration and study of the sea’s marine life to the point where much of it still remains a mystery.

Silvana González, a PhD student at the University of Washington School of Aquatic and Fishery Sciences, uses acoustic techniques to collect data in otherwise inaccessible locations. In high-latitude marine ecosystems, like the Chukchi Sea, traditional vessel-based sampling for fish and zooplankton is only possible in seasons without sea ice. This limiting factor results in an incomplete picture of the life history of these species and the ecosystem as a whole. By utilizing remote acoustic measurements recorded throughout the year and under the sea ice, González is able to piece together a more complete picture of arctic marine life.

A new study led by González, shows the abundance and behavior of fish and zooplankton in the NE Chukchi Sea is mainly influenced by factors that vary at different time scales. The results were published March 18 in Polar Biology.

This research study is part of a broader project, the Chukchi Ecosystem Observatory (CEO), a multi-institutional, multi-investigator partnership that operates and maintains a subsurface moored observatory on the NE Chukchi shelf. The observatory records biological and physical measurements with high temporal resolution throughout the year.

The researchers combined the CEO’s continuous environmental data with new data from a scientific echosounder, a non-invasive sampling method that uses sonar to quantify zooplankton and fish in the water column.

“Our findings indicate variability in fish and zooplankton abundance and behavior occurs at distinct temporal scales: daily, seasonally, and annually,” said González. These scales are different for fish and zooplankton groups and are associated with different environmental drivers.”

Having multi-year, continuous observations in an area where sampling had been limited by the presence of sea ice, the researchers were able to make the following conclude that:

  • Daily vertical migrations are present throughout the year, but are strongest in autumn when day-night cycles are pronounced.
  • Seasonal variability in zooplankton abundance and behavior occurs at scales of 3-to-4 months and is mainly associated with sea ice patterns, which may also regulate the onset of primary production, whereas seasonal variations in fish abundance and behavior are associated most closely with salinity patterns (~ 3 months) and slower changes in water temperature (~ 6 months). 
  • Annual cycles in biological characteristics are influenced by year-round variations in water temperature, sea ice concentration, light irradiance, and wind.

These novel findings indicate that extrapolating patterns observed in short summer sampling windows, where lack of sea ice makes traditional survey methods possible, may not be representative of patterns occurring at other times of the year.

“Biological patterns and their associations with environmental factors vary through time and emphasize the importance of high-resolution long-term studies for comprehensive ecosystem characterizations,” said González.

The team’s time-based characterization of biological variability in the Chukchi Sea identifies the appropriate time scales of observation that should be used in Arctic monitoring programs. This allows researchers to predict and detect biological responses to rapidly changing environments, like those impacted by climate change, with greater accuracy. Predicting the potential direction and magnitude of these changes will help scientists design or improve mitigation strategies and manage Arctic marine species.

Research is ongoing to determine if the observations from the CEO are occurring elsewhere in the Arctic. The installation of additional research observatories enables comparison of similar temporal scales throughout the Arctic and Antarctic, adding to our understanding of the planet’s more extreme marine environments.

Co-authors include John Horne, a UW professor of aquatic and fishery sciences, and Seth Danielson, associate professor, University of Alaska Fairbanks College of Fisheries and Ocean Sciences.

Support for this research came from the North Pacific Research Board Graduate Student Research Award and the Oil Spill Research Institute Graduate Research Fellowship. The Chukchi Ecosystem Observatory receives operations and equipment funding from the North Pacific Research Board and the Alaska Ocean Observing System.

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. Their results were published on March 22 in Global Change Biology.

Megan Feddern, the study’s lead author and a graduate student at the University of Washington School of Aquatic and Fishery Sciences, is analyzing harbor seal skulls from museum collections to piece together what food webs looked like in the past. The museum specimens—some dating back nearly 100 years—were collected from coastal Washington and the Salish Sea north to the Gulf of Alaska and the eastern Bering Sea.

Feddern explains that museum specimens like these can help create historical datasets. The composition of the bone provides researchers with a window into the seals’ diets for roughly the last year of their life. The different environmental conditions at the time could influence nutrients available to the food chain where harbor seals were feeding.

“We know that harbor seals eat a variety of fishes, making them good indicators of a general view of the whole food web, which allows us to measure many different food web pathways,” said Feddern.

As predators, harbor seals are found at the top of their aquatic food chain, whereas primary producers, like phytoplankton, are at the bottom. The environmental conditions present at a given point in time can dictate the abundance and variety of prey items available. Based on signatures from the seals’ diet, researchers can characterize nutrients and primary producers present and compare it to the environmental conditions at that time.

Environmental conditions, such as freshwater discharge, upwelling, and Pacific Decadal Oscillation (PDO), impact nutrients—like nitrogen and carbon—that are available for use by the food web’s primary producers. These nutrient levels are passed up the food chain and imprinted into the seals’ bone.

“What we’re trying to do is link the environmental conditions to the top predator’s food web and that’s something that is not always considered,” said Feddern. “Some studies look at the environmental conditions and compare them to species abundance, but they don’t usually factor in the productivity of primary producers or what links that environment to that species.”

Mechanisms of environmentally induced changes in nitrogen and carbon resources (a–d) which are assimilated into the stable isotope ratios of primary producers (1 and 2), and the stable isotope ratio is conserved when assimilated into consumers at higher trophic levels in the food web. Megan Feddern

By measuring values of source amino acids in these specimens, the researchers derive indices of primary production and nitrogen resources that were assimilated into food webs. The strength of the indices’ response to various conditions over the past century differs widely across the northeast Pacific’s ecosystems.

Primary production and nitrogen availability in the Gulf of Alaska were dependent on regional climate events like the North Pacific Gyre Oscillation and upwelling. By contrast, the coastal Washington and Salish Sea food webs were associated with local indices of freshwater discharge. Feddern believes this is due to fewer anthropogenic factors like agricultural runoff in Alaska, where the food web is driven more by nutrients from natural upwelling.

The results also showed that since 1975, above average ocean conditions in the Gulf of Alaska have altered the composition of primary producers, whereas a similar change was not detected in the Puget Sound region.

“When we get these large-scale climatic changes in something like the PDO, we’re going to see different responses in nutrients and primary production in the Gulf of Alaska food web compared to the Washington food web,” said Feddern. “There are really big regional specific responses in these food webs that make it important to consider some of the spatial complexity when we’re trying to think about how PDO or sea surface temperature might be impacting marine life.”

Looking ahead, researchers know that climate change will influence nutrient cycling and primary production in the world’s oceans, dictating variable impacts on coastal food webs. Using museum specimens as record keepers of the past can provide insight into the future.

“By understanding how the environment impacted nutrients important to coastal food webs in the past, we can anticipate how future environmental changes may impact food webs,” said Feddern.

Additional UW co-authors include Gordon Holtgrieve, a professor of aquatic and fishery sciences, and Eric Ward, an affiliate faculty at the School of Aquatic and Fishery Sciences.

This research was funded by Washington Sea Grant and a Joint Institute for the Study of the Atmosphere and Ocean Grant.

Jeff Cordell Retires after 43 Years at SAFS

When Jeff Cordell was around nine years old, he decided that he wanted to be a marine biologist. Growing up near Puget Sound, he spent many summer and weekend days at the beach and in the water, collecting and identifying all kinds of invertebrates.

Later, as an undergraduate at Huxley College of Environmental Studies, Jeff worked in a lab, sorting and identifying biota from Puget Sound beaches; he also spent three summers working in the Arctic, collecting invertebrates before oil drilling commenced there.

After graduating from college, Jeff got a job at the (then) School of Fisheries, working at the Big Beef Creek research station, sorting and identifying salmon diets and invertebrate samples, and being part of impact studies of the new Trident submarine base on Hood Canal. This was the start of his collaborations with Charles “Si” Simenstad and the Wetland Ecosystem Team (WET), which have lasted for 43 years. Jeff eventually became manager of the taxonomy lab on campus, got his MS, and became a SAFS principal investigator.

“For over 40 years, Jeff has been a uniquely strong collaborator and research initiator for WET. He and I have integrated our scientific curiosities over diverse estuarine/coastal ecosystems—his infinite detail of epibenthic and pelagic invertebrate taxonomy and ecology inter-facing with my wider view of food webs and estuarine habitat associations. We have collaborated on journal publications and innumerable technical reports. Although he is stepping back from full-time academic pursuits, I expect that he will continue to contribute rare insights into the ecology of these unique estuarine fauna.”

—Charles “Si” Simenstad, Professor Emeritus

When asked about his most memorable projects, Jeff named several favorites: conducting plankton surveys in west coast estuaries; working with the Smithsonian Institution to investigate patterns of invasive invertebrates along the east and west coasts of the United States; evaluating floodplain and estuary restoration efforts throughout the region; conducting a study of non-indigenous organisms being discharged from ships’ ballast into Puget Sound; and working on long-term studies of the biology and ecology of the lower Columbia River. Recently, Jeff has been monitoring the function of restored wetlands within Seattle’s industrialized Duwamish waterway and also developing and implementing fish-friendly habitat that has been incorporated into Seattle’s new seawall.

Jeff said, “It is great to be able to give something back to my home region.”

Jeff credits SAFS and WET for giving him the opportunity to have a non-traditional career in an academic setting. He explained, “As a non-faculty researcher, I would guess that there aren’t too many places that would have allowed me to stretch intellec-tually and go on to lead my own research and to mentor and support graduate students.” He also emphasized that his relationships with faculty, colleagues, and students have been special to him.

Jeff said that over his 43 years at SAFS, “The biggest changes are the complete turnover in faculty and the broadening in focus from research on aquaculture, fish stocks, and fisheries to more holistic ecosystem studies.” He noted that, in a more general sense, “the biggest change has clearly been the development of technologies in computers and monitoring equipment.”

Jeff feels fortunate that his retirement plan allows him to return to the UW as a part-time employee. He plans to continue his work with students and staff on his favorite research projects.


Keeping SAFS Running During a Pandemic

Up until last March, the classrooms, labs, offices, and even the hallways and lobbies of the Fishery Sciences and Fisheries Teaching and Research buildings were bustling with the regular activities of a vibrant academic unit. During this past year, however, our daily routines have changed dramatically; our days now consist of Zoom calls and juggling an increasingly stressful work-life balance at home.

Amidst all of these changes, building coordinator Jon Wittouck’s role has become even more vital. Jon, along with co-worker Jason Ching, is still coming to campus nearly every day, working behind the scenes to ensure that the SAFS facilities are safely maintained and operations are running smoothly for critical employees.

Jon explained that College of the Environment building coordinators, working together with Associate Dean Stephanie Harrington, standardized building processes as much as possible, based on the University’s COVID-19 safety guidelines.

Currently, there are several SAFS groups conducting essential research in the buildings, including the Wetland Ecosystem Team and the Padilla-Gamiño, Wood, Schindler, Taub, and Roberts labs.

Jon has assisted SAFS faculty by helping design hybrid lessons for multiple courses, which combine in-person and online activities. These include Autumn Quarter’s FISH 406 Parasite Ecology and Winter Quarter’s FISH 427 Tropical Marine Biology.

“For the Tropical Marine Biology class, we sent at-home lab kits to students that included live sea anemones and fertilizer treatments. When we first conceived this idea, we immediately went to Jon for advice,” said course professor, Jacqueline Padilla- Gamiño. “He was quick to point out several safety concerns that we hadn’t thought about and worked with us to navigate how to follow proper safety protocols by mediating discussions with Environmental Health and Safety. Additionally, he has been an invaluable resource for obtaining lab supplies for class activities, both before COVID when we had labs in person, and since COVID when we shipped them to students.”

For on-campus labs, there are spacing and equipment limitations, such as sharing setups and enhanced cleaning requirements to consider. Jon said that he and faculty members work collectively to put together a model of what all these setups could be. Some instructors have even taken to filming their labs so that students can view the experiments from home, further reducing the number of people on campus.

Jon is now planning for spring quarter courses that will follow a similar model, including FISH 312 Fisheries Ecology, which traditionally has multiple field components. As one can imagine, this takes a lot of thought, resourcefulness, and creativity.

“We’re trying to make sure the students are having a fruitful learning experience, but it’s a challenge because you certainly can’t do as much as in person,” said Jon. “Some of the hands-on work the students do is applicable later in their careers. We’re doing what we can to make sure that, whether through video recordings or limited in-person labs, students can see it happening so they can understand the process.”

 


Capstone Highlight: New Species of Damselfish

Emily McFarland

Capstone research projects provide an exciting opportunity for students to put classroom learning into practice—and sometimes even publish their work. These senior projects are the culmination of the undergraduate experience here at SAFS.

Emily McFarland (BS 2020) published her capstone, “A new species of Chromis damselfish from the tropical western Atlantic (Teleostei, Pomacentridae),” this past December. The new species—Chromis vanbebberae —was revealed through phylogenetic analyses to be distinct from Chromis enchrysurus, commonly known as the Yellowtail Reeffish.

Emily recalls during her first tour of the UW Fish Collection as a freshman, it was mentioned that students sometimes get the opportunity to describe new species.

“I became fixated on that idea in addition to working in the fish collection lab in general,” she said. “I started working with Dr. Luke Tornabene in the spring of that same year while taking FISH 311 (Biology of Fishes), helping with the molecular work for dwarf goby phylogeny research.”

Looking to get an early start on her capstone, in her junior year, she discussed the possibility of describing a new species with Luke. He pointed her in the direction of a suspected new species of damselfish that had been observed on expeditions in the Caribbean as part of the Smithsonian’s Deep Reef Observation Project. It was the perfect opportunity to apply her growing knowledge in systematics, phylogeny, and taxonomy.

The damselfish Chromis enchrysurus was initially described in 1882. That description was later revised in 1982 to account for an observed color morph that possessed a white tail instead of a yellow tail. Emily’s study would definitively show that the white-tailed damselfish is actually its own distinct species.

In her paper, she writes, “the discovery of a new species within a conspicuous group, such as damselfishes, in a well-studied region of the world highlights the importance of deep-reef exploration in documenting undiscovered biodiversity.”
