Curry Cunningham

Curry Cunningham (MS)
curryc2@uw.edu

Curry is a former Bristol Bay commercial fisherman and received his B.S. in Animal Biology from the University of British Columbia, Vancouver. His current graduate research at the University of Washington is partitioned into four categories. First, the evolutionary ecology of sockeye salmon in Bristol Bay Alaska, specifically evaluating interactions between selective pressure from predation, harvest, competition, and sexual processes. Second, statistical approaches to allocating catches of Bristol Bay sockeye and estimating interception rates among spatially segregated fishing districts with the purpose of reconstructing annual return sizes. Third, improving established techniques for preseason and real-time forecasting of sockeye salmon returns, by incorporating biological and environmental data. Fourth, modeling the population dynamics of threatened and endangered Chinook salmon populations in California’s Sacramento River watershed, to determine the critical environmental drivers of survival from anthropogenic and natural sources, and evaluate the effect of competition with hatchery reared stocks.

Fred Goetz

Fred Goetz (PhD)
Frederick.A.Goetz@NWS02.usace.army.mil

Fred received his M.S. from Oregon State University where he studied the ecology of bull trout and since then he has worked for the U.S. Army Corps of Engineers as a fish biologist studying the movements of salmon and trout in Puget Sound. In his professional work, Fred has evaluated fish passage and habitat conditions at several Corps dams and navigation projects including in the Green River, White/Puyallup Rivers, the Ballard Locks, and the Snohomish, Stillaguamish, Skagit, and Nooksack Rivers.

At the Locks Fred helped design and evaluate a fish passage system for protection of migrating salmon smolts. In development of the system, he tested and evaluated three behavioral guidance techniques (low-frequency sound, strobe lights, and slowing the fill rate of the lock) to keep smolts from becoming entrained in the filling system for the locks. Strobe lights and slowing the fill rate were found to be effective in reducing entrainment and these techniques are now part of the smolt passage system. As part of this work at the Locks, Fred helped develop a long-term monitoring plan for the Lake Washington system by including PIT-tag monitors in flumes that are designed to pass smolts from freshwater to Shilshole Bay. Juvenile Chinook and coho salmon have been tagged in various Lake Washington tributaries and monitored with the readers since 2000. As part of an assessment of dredging projects in Puget Sound rivers, Fred has been monitoring bull trout behavior and habitat use in estuary and nearshore areas in northeast Puget Sound since 2002. This work is the first research to study the anadromous life history type of bull trout. This research is being used in recovery planning for ESA-listed Puget Sound bull trout.

His dissertation project is a multi-species investigation of salmonid movements using ultrasonic telemetry. Working in cooperation with a large number of investigators from various agencies (e.g., NOAA-Fisheries, Washington Department of Fish and Wildlife, Seattle City Light, Nisqually Tribal Fisheries Office) he has been tagging steelhead, anadromous cutthroat trout and bull trout, and coho and Chinook salmon. These species range from those thought to invariably migrate to the Pacific ocean for feeding (steelhead), to species that may reside in Puget Sound or migrate to the coast (coho and Chinook salmon) and those thought to invariably remain within Puget Sound, near their natal rivers (cutthroat and bull trout). The telemetry study should provide insights into the basic biology of these species and also facilitate conservation efforts.

Rachel Hovel

Rachel Hovel (PhD)
rhovel@u.washington.edu
Rachel's website

Rachel is broadly interested in the processes of community ecology in freshwater systems and the ways in which organisms cope with habitats that vary in time and space. Her dissertation research focuses on fish communities in large coastal lake systems, and explores how diversity among and within species affect species interactions in variable environments. Current projects include work in the Wood River lakes of Bristol Bay, Alaska, where shifts in community composition and the expression of life history events are explained with climate change signals over a five decade time series. Other research in Lake Washington seeks to answer questions of how phenological diversity helps buffer against seasonal variability in resources, and how species interactions can shape foraging behavior in a pelagic food web.

Mike Tillotson (PhD)
mdt3@uw.edu

 

            Mike was born in Seattle and during a childhood spent salmon fishing from Puget Sound beaches he developed a profound interest in salmon and their peculiar life history. While obtaining his bachelor of arts in environmental studies and anthropology at Bowdoin College in Brunswick, Maine, it was the study of local, depleted Atlantic salmon runs and working in the Bristol Bay sockeye salmon fishery during the summer that helped  him to develop an appreciation of the interconnectedness of human and ecological systems. After working in environmental consulting for two years Mike decided to continue his study of marine social-ecological systems at the University of Washington’s School of Marine and Environmental Affairs where he received his M.M.A in 2013. As a doctoral student at the University of Washington’s School of Aquatic and Fishery Sciences Mike continues to allow his passion for understanding, protecting and catching salmon to  guide his studies. His interdisciplinary research explores the relationships between climate change, marine and aquatic ecosystems, salmon and the people who depend on them.

Neala Kendall

Neala Kendall (MS 2007, PhD 2011)
kendalln@u.washington.edu
Neala's website, CV, and dissertation

Neala Kendall received her BA in biology from Kenyon College in Ohio. After a three-year stint doing environmental consulting in northern California she moved to Seattle to begin her graduate work at SAFS. For her master's thesis, Neala quantified fishery selection by a gillnet fishery on age and size at maturity of sockeye salmon in Bristol Bay, Alaska. She examined selection from 1946-2007 at two scales, the Nushagak District (Kendall et al. 2009), and individual spawning populations within the Wood River system that differ in age and size at maturity (Kendall and Quinn 2009).

Neala extended this project for her PhD, for which she investigated potential life history evolution resulting from this fishery selection. Neala first worked on a project to analyze long term data on age and size at smolt transformation and maturation of wild and common garden-reared Columbia River sockeye salmon populations to better understand how genetic and environmental effects impact age and size at maturation (Kendall et al. 2010 ESR). She found that genetic effects play a role in influencing these traits, suggesting that fishery selection has the potential to result in evolutionary changes in Pacific salmon. In other PhD chapters Neala has used vulnerability profiles and selection differentials to quantify commercial fishery selection on Bristol Bay, Alaska sockeye salmon across fishing districts where different types of fishing gear is employed (Kendall and Quinn in prep) and both commercial and recreational fishery selection on one population of Bristol Bay Chinook salmon (Kendall and Quinn 2011 TAFS). Finally, in the remaining chapters of her dissertation Neala tested the hypothesis that trends in age and size at maturation of Bristol Bay sockeye salmon are driven by environmental effects in conjunction with selective fishing and teasing apart phenotypic plasticity and genetic changes using probabilistic maturation reaction norms and quantitative genetics models. Neala enjoys the balance of fieldwork and quantitative analyses employed in her research, and she has also appreciated her recent classes in science communication.

After graduating, Neala became a Post-Doctoral Research Assistant at the Northwest Fisheries Science Center.

Jessica's thesis

For her M.S. research, Jessica examined the phenomenon of partial migration in Puget Sound Coho Salmon. The project approached the problem from both the population and individual level using complementary data: 1) data from a network of acoustic telemetry receivers within the Puget Sound to allow investigation of the small-scale vertical and horizontal movements of individuals, and 2) analysis of coded wire tag records of Puget Sound hatchery and wild coho to reveal internal and external factors that make coho more likely to remain resident in Puget Sound.

Jessica is passionate about science communication. After graduating, Jessica went on to help her colleagues at SAFS improve their web presence, teach graduate students to better communicate their research at the Engage Seminar, and build science communication tools for Conservation Magazine.

Pamela Woods (dual PhD degree, UW and University of Iceland, 2011)
pamelajwoods@gmail.com
Pamela's dissertation [PDF]

Pamela earned a dual doctoral degree between the University of Washington and the University of Iceland. This is the first such dual degree that the University of Washington has allowed with an external university. As part of a European Research Training Network, FishACE, she began her dissertation in January 2008 by studying evolutionary patterns of divergence in Arctic char populations, and how these relate to local ecological conditions of lakes across Iceland. Her supervisors are Skúli Skúlason (Hólar University College, Iceland), Siggi Snorrason (University of Iceland), and Thomas Quinn (University of Washington). She continued with a comparison of Icelandic freshwater food webs and those at field sites in Alaska, another high-latitude region that is geologically older and more biologically diverse. These projects will aid natural resource management by yielding an understanding for how environmental issues, such as global climate change or exploitation, may affect the ecology of freshwater systems. 

After graduating, Pamela became a Post-Doctoral Research Assistant in the Marice lab with Dr. Guðrún Marteinsdóttir (Iceland).

Joseph Anderson (MS 2007, PhD 2011)
joeander@uw.edu

Joe Anderson's research in the Quinn lab investigated the process of salmon colonization on a local Washington river where the construction of fish passage facilities have permitted coho and Chinook salmon to access habitat they had been denied for over 100 years. His M.S. thesis work described the movements of adult coho salmon in the new habitat (Anderson and Quinn 2007), as well as the distribution of juvenile coho in relation to adult spawning sites (Anderson et al. 2008). His dissertation research employed molecular genetics to evaluate the individual and population-level reproductive success of both coho and Chinook salmon during colonization.

After graduating, Joe became a Post-Doctoral Research Assistant at the Northwest Fisheries Science Center.

Thomas Buehrens

Thomas Buehrens (MS, 2011)
Thomas' Thesis [PDF]
tbuehren@uw.edu

Thomas' research in the Quinn lab investigated the ecology of rainbow and cutthroat trout in the Cedar River, Washington. Fish populations in this river were segregated in 1901, when a diversion dam was built, preventing migratory fish from accessing the upper watershed. Trout populations living in the river upstream of the dam were forced to adopt resident life histories and were isolated from below-dam populations of trout and anadromous Pacific salmon. In 2003, modification of the dam restored passage for migrating fish, and allowed coho and Chinook salmon to spawn above the dam. Thomas investigated the effects of restored habitat connectivity and colonizing salmon on coastal cutthroat and rainbow trout. His methodology employed Passive Integrated Transponder (PIT) tags to study the growth, movement, and survival of trout, molecular genetics to distinguish between trout species and hybrids, and stable isotope chemistry to relate growth and movement of individual trout with potential forage resources.

After Graduating, Thomas became a Research Fishery Biologist with Wild Fish Conservancy.

Todd Seamons

Todd Seamons (PhD, 2005; Post-Doc, 2011)

Todd's research with the Quinn lab investigated the evolution of fitness traits of fishes in natural and human-manipulated environments, utilizing molecular and quantitative genetic methods to 1) to determine evolutionary processes in fish populations and 2) investigate the impacts of management and conservation on these processes. His work specifically focues on salmonids, which have diverse life histories, are of significant regional management and conservation interest and are cultured on an extensive scale. He also used genetic tools to investigate impacts of hatchery steelhead on wild populations.

After completing his post-doc, Todd went to work with the Washington Department of Fish and Wildlife.
