Phylogeography of ants from the Brazilian Atlantic Forest
Known for its remarkable biodiversity and high levels of endemism, the Brazilian Atlantic Rainforest has been characterized as one of the most threatened biomes on the planet. Despite strong interest in recent years, we still lacka comprehensive scenario to explain the origin and maintenance of diversity in this region, partially given the relatively low power of analyses involving few independent genetic loci. In this study, we examine a phylogenomic dataset of five ant species to investigate phylogeographical patterns across the Brazilian Atlantic Forest. We sequenced ultraconserved elements to generate hundreds of loci usinga bait set developed specifically for hymenopterans. We analyzed the data using Bayesian and maximum likelihood approaches of phylogenetic inference. Results were then integrated with environmental niche modeling of current and past climates, including the Last Glacial Maximum and the last interglacial period. The studied species showed differentiation patterns that were consistent with the north/south division of the Atlantic Rainforest indicated in previous studies for other taxa.
