We are overjoyed to announce that NSF is funding a collaborative research project to look at the genomic underpinning of local adaptation in the Atlantic silverside! Check out the project website designed by our collaborator Hannes Baumann to learn more.
We have now finished setting up our second laboratory, which is exclusively dedicated to pre-PCR work with ancient and historical samples. The room has UV irradiation at night, positive air pressure with all incoming air passing through a HEPA filter, and restricted access in protective clothing - all to minimize the risk of contamination. We are excited to start recovering DNA from cod bones excavated from archaeological sites and work with other ancient samples in the future.
Former postdoc Dr. Aryn Wilder has moved to California to start her new job as a conservation genetics researcher at the San Diego Zoo. Congratulations Aryn! We will miss you!
PhD students Maria and Nicolas presented their research at the Annual Ecology and Evolutionary Biology December Symposium. Nicolas discussed the effects of quantitative trait architecture on detection power in artificial selection experiments. Maria presented her Master’s research examining geographic variation in male and female reproductive behavior in red-eyed treefrogs, and was awarded the best first-year EEB student talk. Well done, Maria!
We're thrilled to announce that the Therkildsen lab, in collaboration with Dr. Philipp Messer, has received seed funding from the Center for Vertebrae Genomics (CVG) at Cornell University for our research using historical DNA samples to characterize the genomic basis for fisheries-induced evolution in Atlantic cod.
Maria has also been awarded a CVG Scholars Program Award in support of her work on the cytogenomics of local adaptation in the Atlantic silverside. Congratulations to Maria!
The Therkildsen Lab held an informal workshop with hands-on instruction on executing our low-coverage sequencing pipeline (Therkildsen and Palumbi 2017). Dr. Gemma Clucas (Postdoc at University of New Hampshire) joined us for the workshop, which was led by our very own Dr. Aryn Wilder. Thank you Gemma for visiting, and Aryn for leading!
The Therkildsen lab is collaborating with Dr. Anne-Marie Dion-Côté (Postdoc in Barbash Lab at Cornell) to characterize the genomic architecture underlying local adaptation in the Atlantic silverside. Dr. Dion-Côté is training Maria Akopyan (PhD student in our lab) on cytogenetic analysis to characterize chromosomal variation between populations of the Atlantic silverside. Maria has been busy in the lab preparing metaphase spreads from regenerating fin tissue of silversides. Check out the photos from the lab below, including a karyotype of an individual from the New York population!
Aryn just came back from Hannes Baumann's Lab at the University of Connecticut with silverside juveniles we had spawned and raised there. We have two sets of offspring, one from parents collected in Georgia and another from parents collected on Long Island, New York. Fish from these locations have vastly different intrinsic growth capacity and also show genetic differences in a host of other traits.
We will continue to raise these fish here at Cornell so we can do cytogenetic analysis (in collaboration with Anne-Marie Dion-Côté) to compare the karyotypes of fish from the two populations.
