Welcome to the Scordato lab! We investigate the effects of long-term anthropogenic landscape modification on the behavior, ecology, and genetics of wildlife- mostly birds. 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.
