Welcome to the Walsh LabWalsh Lab News
Sediment Coring - Madison, WI
February 2018 Dr. Matthew Walsh, Post-Doc Dr. Jared Goos, and Ph.D. candidate Michelle Packer met up with Mark Shapley from LacCore to complete sediment coring in iced-over lakes as part of a new project. This is the first step in investigating plasticity's role in evolution under Dr. Matthew R. Walsh's new CAREER grant: "Does behavioral plasticity promote or constrain adaptation? A test using resurrection". Cores will be dated using Pb-210 to help isolate Daphnia from resting-eggs in sediments that predate invasion of the lakes by Bythotrephes longimanus. Hatched clones will be compared with Daphnia from contemporary populations, looking for differences in plasticity and evolved behavioral traits. 
We are excited to be welcoming Dr. Michael (Michi) Tobler to speak as part of the UTA Department of Biology 2018 Colloquium Series.
February 22, 2018 Dr. Michael (Michi) Tobler Associate Professor Division of Biology Kansas State University Dr. Tobler is an evolutionary biologist addressing fundamental questions about the origins of functional trait diversity and speciation. Specifically, he is using extremophile, live-bearing fishes to determine how genetic, ecological and functional factors result in convergence at macroevolutionary scales, and testing when and why evolutionary change is repeatable and predictable. His talk will be titled "Extreme Environments, physiological adaptation, and the origin of species". 
Dr. Yoel Stuart joined us to speak at the UTA Department of Biology Fall 2017 Colloquium Series.
October 19, 2017 Dr. Yoel Stuart Postdoctoral Associate Department of Integrative Biology University of Texas at Austin Yoel's lecture was titled "Parallel evolution is a continuum. Case studies in anoles and stickleback". 
Matt Walsh wins NSF Career Grant to study effects of predators on the evolution of Daphnia.
July, 2017 Congratulations to our awesome PI and advisor for being awarded a five-year, $600,000 grant from the NSF’s Faculty Early Career Development Program. The project is titled “CAREER: Does behavioral plasticity promote or constrain adaptation? A test using resurrection.” Members of the Walsh Lab gave presentations at Evolution 2017 Confernce in Portland, Or.

Investigations into Eye-Brain size in Killifish - Winter Field Season 2016
December, 2016 Over winter break PhD candidate Shannon Beston, undergrad lab alum Kaitlyn Howell, and Dr. Walsh returned to Trinidad to determine how selection on eye size and brain size is operating in natural populations of Trinidadian killifish Rivulus hartii. Recent work by Beston and Walsh has shown that both brain size and eye size decrease significantly in sites with high rates of predator induced mortality. To begin to address why predators are associated with smaller brains and eyes, the three executed a short term mark-recapture experiment to evaluate survival and growth rate as a function of eye size and brain size. As an added bonus, the Walsh Lab now has 130+ live Rivulus that will be used for a variety of laboratory experiments. Stay tuned for some exciting results!
