Coalescent species delimitation in milksnakes (genus Lampropeltis) and impacts on phylogenetic comparative analyses.

Abstract excerpt

Both gene-tree discordance and unrecognized diversity are sources of error for accurate estimation of species trees, and can affect downstream diversification analyses by obscuring the correct number of nodes, their density, and the lengths of the branches subtending them. Although the theoretical impact of gene-tree discordance on evolutionary analyses has been examined previously, the effect of unsampled and...
