Geographic variation in Bartram's round-winged katydid, Amblycorypha bartrami

This study examines the geographic variation in the calling song, morphology, and ecology of Bartram's round-winged katydid, a species that is distributed in longleaf pine ecosystems along coastal southeastern United States. Sequences of genomic DNA (5 genes) from 18 individuals from 7 populations across the southeastern US were used to determine the phylogenetic relationships among the populations. The goal was to determine whether differences in songs found among populations correlated with divergences in the phylogeny.
