Walsh Lab News
Matt Walsh wins NSF Career Grant to study effects of predators on the evoluton of Daphnia.
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 Evoution 2017 Confernce in Portland, Or.
Investigations into Eye-Brain size in Killifish - Winter Field Season 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!
