Welcome to the Scordato lab! We investigate the mechanisms that drive large-scale phenotypic and genomic variation among populations, and determine how that variation contributes to the formation, maintenance, and erosion of reproductive barriers. We use a variety of tools to ask these questions, including next-generation sequencing and genomic analysis, behavioral observations, and long-term ecological and climatic datasets. Check out the website to learn more about our work.

December 7, 2016: Paper on geographic variation in male territorial strategies is accepted at Animal Behaviour! This turned out to be the most difficult paper I've ever written, but also my favorite. You can find it here.
October 5, 2016: Becca and I wrote a dispatch for Current Biology about two excellent new papers on the genomic basis of phenotypic variation across avian hybrid zones (Toews, Taylor et al and Delmore et al). Look for it online in November!
Sept 12, 2016: Returned from ConGen2016- an intensive 5-day course on landscape genomics and next-gen sequence data analysis. Learned a ton, met some great people, and am full of new ideas for how to measure spatial variation in gene flow in barn swallows.
August 8, 2016: Back from the final conference of the summer: ISBE 2016! I participated in an excellent symposium on the role of male competition and speciation. Looking forward to working on a review paper with the other speakers!
June 23, 2016: Just returned from a fantastic Evolution meeting in Austin, TX, where current and former CU folks all gave great talks. I presented some new barn swallow data in the genomics spotlight session. It was exciting to hear all the great feedback and new ideas.
June 15, 2016: Paper with Becca Safran, Nolan Kane, and many other excellent colleagues accepted at Molecular Ecology. This one was a long time coming- we're very excited!
May 15, 2016: Our NSF pre-proposal, written with Becca Safran, Iris Levin, and Bailey Fosdick, was invited! We're hoping to return to some barn swallow hybrid zones and experimentally test patterns of assortative mating. July just turned into a mega writing month.
May 9, 2016: Back from a tremendously successful 3-week sampling trip to Morocco. We caught 160 birds at four different sites, hopefully sampling across a migratory divide. Updates coming soon to the blog.
January 17, 2016: An excellent meeting of the American Society of Naturalists in Asilomar, CA. Always nice to see great scientific talks in a fantastic natural setting.
