Ancestral area analyses reveal Pleistocene-influenced evolution in a clade of Coastal Plain endemic plants

AIM: The North American Coastal Plain is currently recognized as a global biodiversity hotspot. However, the mechanisms driving high levels of species richness in a region with relatively low topographic relief and homogeneous climate are unclear. We investigated the evolutionary processes driving ancestral area evolution and diversification in a biodiversity hotspot from both a systematic and biogeographic context using a clade endemic to the hotspot.
LOCATION: North American Coastal Plain
TAXON: The Scrub Mint clade comprises Dicerandra, Conradina, Piloblephis, Stachydeoma, and four species of Clinopodium (Mentheae; Lamiaceae), almost all of which are endemic to the North American Coastal Plain. 
METHODS: We generated a dated phylogeny using a target enrichment/capture dataset and then calculated ancestral area using biogeographic models. We uncovered neo- and paleo-endemism hotspots and inferred ancestral potential ranges at each node based on ancestral niche reconstructions and pale..., , , ## Provenance for this README

Description: an aligned Nexus file with all genes and loci used to run phylogenetic analyses.

Size: 8.56 MB

Notes on this file:
There are 242 genes included in this matrix for 24 species (g010 failed to be sequenced entirely). Of those, 238 were used to build the gene trees for subsequent analyses. The genes that were left out are as follows:

DNA, g017.FNA = 20212-21966

DNA, g098.FNA = 130980-131237

DNA, g163.FNA = 218581-218870
