Abstract
On mountains, climate varies elevationally, applying different selective pressures on organisms. This study aims to use the fruit fly species, D.affinis along elevational transects to test for local adaptation of thermal tolerance and life history traits and quantify gene flow between populations. To investigate elevational differences, fly lines were derived from Camel’s Hump Mountain, Vermont. Metrics for thermal tolerance and life history traits were measured and a phylogenetic tree was constructed using mitochondrial Cytochrome c oxidase subunit I gene sequences. Evidence for improved cold tolerance at higher elevations was found, suggesting that colder climates have resulted in local adaptation
