Dr. Peter Westley, SEEC Lab PI

Peter is a life-long Alaskan. He obtained BS and MS degrees in Aquatic and Fishery Sciences at the University of Washington and a PhD at Memorial University of Newfoundland. He is fascinated by the patterns of fish diversity in nature and explores the ecological and evolutionary underpinnings of those patterns. By using examples from colonization, hatchery wild salmon interactions, invasion, and climate change he and his students explore the causes and consequences of fine scale adaptive change in salmonid and other freshwater fishes.

Postdoctoral Researchers

Kristawsockeye.JPG

Dr. Krista Oke

Krista joined the lab in 2018 as a Centennial Postdoc working on an NCEAS State of Alaska Salmon and People (SASAP) working group project synthesizing patterns, causes, and consequences of body size declines in Alaska salmon. She is currently focused on walleye pollock, investigating the impacts of recent exceptionally warm temperatures in the Bering Sea on pollock body size and local abundances. Krista is broadly interested in evolutionary ecology and has ongoing field projects following experimental stickleback populations in Southcentral Alaska. Check out Krista’s website here

Current Graduate Students

Ben_Rich_photo.jpg

Benjamin Rich

MS Candidate

Ben joined the lab in Spring 2021 and is studying the distribution and bioenergetics of Northern Pike in Southcentral Alaska in cooperation with the US Fish and Wildlife Service. 

Maddy_Lee_photo.png

Madeline Lee

MS Candidate

Maddy joined the SEEC lab in the fall of 2020. After a record hot summer in 2019, Maddy noticed behavior of heat stress in Chinook salmon on the lower Cook Inlet salmon streams during her Alaska Department of Fish and Game technician position. Partnering with Woodwell Climate Research Center and United States Geological Survey, Maddy will be assessing the prevalence heat stress in spawning Chinook salmon and quantifying the link between Pacific salmon heat stress presence and spawning success in the subarctic.

Elizabeth Mik'aq Lindley 

MS Candidate

Mik' is studying Pacific salmon in the Arctic with a specific focus on the potential for salmon to successfully spawn in Arctic freshwater systems, and how Arctic thermal regimes might influence timing of important life events (phenology) during incubation. Through collaboration with the Department of Fisheries and Oceans Canada Arctic Salmon Project, Mik' is conducting a common garden experiment to quantify lower thermal limitations during incubation. Mik' is also working closely with the Alaska Arctic Observatory and Knowledge Hub to track observations of unusual salmon occurrences in Alaskan Arctic coastal communities.

Molly Payne 

MS Candidate

Molly joined the SEEC lab in the fall of 2019 to better understand the factors that make some rivers more attractive to hatchery strays than other rivers in Southeast Alaska. Molly received the prestigious DIPAC Graduate Fellowship.

Lab Alumni

Eric.jpg

Eric Walther
MS

Eric worked with the Washington Department of Fish and Wildlife to construct a watershed prioritization map for the Chehalis River in Southwest Washington State. Using extensive on-the-ground sampling, Eric built intrinsic potential models to assess fine scale habitat potential for coho salmon and steelhead. Eric is currently pursuing a PhD in Ecology at the University of Georgia. You can learn more here

Julia.png

Julia McMahon

MS

Straying by Pacific salmon is a fundamental aspect of their biology, yet also mediates the interaction between wild and hatchery fish on the spawning grounds. Julia worked in Prince William Sound in conjunction with a larger multi-year study, where she sought to understand the ecology of strays. Julia was supported by a fellowship from the Rasmuson Fisheries Science Center.

Michelle Stratton

MS

Is there really more to know about Buskin River adult coho salmon? As it turns out there is a ton! For her thesis, Michelle demonstrated the importance of holding habitat for fish prior to spawning, particularly Buskin Lake. Michelle is currently working as the Assistant Area Management Biologist for the Alaska Department of Fish and Game in Chignik, AK.

Marta Ulaski

MS

For her thesis, Marta quantified the strength and form of selection acting on body size of smolt sockeye salmon on Kodiak Island. Was Yoda right? "Size matters not". Marta is currently pursuing a PhD in Fisheries Science at Simon Fraser University. You can learn more here

Chase Jalbert

MS

In every invasion there is a silver lining. Chase explored the population structure of introduced northern pike using ddRAD sequencing approaches and conducted the first watershed risk analysis to guide conservation and suppression efforts to the on-going pike invasion. Chase currently works as a project leader at the Alaska Department of Fish and Game Gene Conservation Lab.

Katja Berghaus

MS

Invasive species are opportunities to explore phenotypic divergence to new habitats. Katja joined SEEC from Germany where she conducted research for her MS that explores contemporary trait change in northern pike introduced to Southcentral Alaska with comparisons to the native range. She is continuing on with a PhD at UAF under the supervision of Trent Sutton.

Dr. Curry

Cunningham

For his postdoc work, Curry formulated a novel stage-based life history model for Yukon River Chinook salmon and found evidence that climate in the ocean and freshwater, plus competition at sea with Asian stocks of chum salmon can explain patterns of survival.  

Dr. Cunningham is an assistant professor in the Department of Fisheries at UAF on the Juneau Campus. You can learn more on his website here

Morgan Sparks

MS

For his MS thesis in the SEEC Lab, Morgan quantified the potential adaptive response of Bristol Bay sockeye salmon to warming water temperatures during spawning and embryo development. He is currently working with Mark Christie's group at Purdue University. Website

Casey McConnell

MS

Understanding the causes and consequences of straying by Pacific salmon is a fundamental and applied question. Casey tackled this by studying straying by hatchery produced chum salmon in Southeast, Alaska and showed that strays enter the spawning grounds later, live fewer days, retain more eggs, are younger and smaller than wild counterparts. He also showed that stress was not obviously linked to straying, though did find that hatchery fish had higher rates of vaterite in their otoliths than wild fish. Casey is currently a small business owner in Hoonah, AK.

Madeline.jpg

Madeline Jovanovich

Madeline worked in the SEEC Lab on the large and ambitious 'State of Alaska Salmon & People' Project. During her time she worked to compile mountains of data on salmon escapement and harvest, hatchery release and return numbers, and in the process became a wiz at data science. She is a life long commercial fisher with roots in Washington State and heart in Bristol Bay.

C. Nathan Cathcart

Nate worked in the SEEC Lab on a diet synthesis of northern pike across Alaska.  Pike love to eat fish when they can, but can persist on insects and each other.

Joe Spencer

Joe completed  his undergraduate senior thesis in the spring of 2018 where he examined the diet and growth patterns in native and invasive northern pike.  Pike love to eat fish...when they can! But they are just fine persisting on insects. They don't eat each other as much as you might have heard or thought.

Cynthia Nelson

Cynthia completed an independent project on the antipredator behavior of juvenile salmonids in Interior and Southcentral regions of Alaska in the context of the northern pike invasion. Her work was supported by an award from URSA at UAF
