New paper looking at life history changes associated with artificial selection on body size!5/29/2024
Our new paper, coauthored by lab technician and Barnard alum Avigayil Lev ('22), has been published in the Journal of Evolutionary Biology! This work, part of a collaboration with Andrew Stewart's lab at Canisius University, uses populations created by Andrew to look at the life history changes associated with >400 generations of artificial selection on body size in Drosophila melanogaster. We found that flies selected for small body size had lower juvenile viability, fecundity, and absolute egg size, but higher relative egg size, than flies selected for large body size. Our findings are consistent with the hypothesis that egg size is a key constraint on body size evolution in this species. Check out Barnard's coverage of this work here.
Today was Olivia Anastasio's last day as the Pischedda Lab Technician. She is leaving to start a new position as a Laboratory Specialist in the Barnard Biology Department. Olivia will be part of our Introductory Biology team, teaching intro bio labs and discussions. We will miss her in the lab, but the department is lucky to have her!
Taking over as our lab tech will be Pischedda Lab alum Avigayil Lev, who graduated from Barnard in 2022 and completed her Environmental Science senior thesis in the lab. We're thrilled she is able to stay on in the lab! Congrats to Mariel Correa-Maynard, Olivia Eliopoulos, and Avigayil Lev who graduated from Barnard today! Mariel earned a BA in Physiological and Organismal Biology, Olivia earned a BA in Cellular and Molecular Biology, and Avigayil earned a BA in Environmental Science! It was Barnard's first in-person graduation since 2019!
