Look who just moved in next door!: Understanding geographical patterns in Neotropical Ruellia (Acanthaceae).

Understanding the origin of species’ ranges defines historical biogeography. Recently, some studies have examined the causes of range overlap of congeneric species. However, these studies have generally included many distantly related clades, with each phylogeny containing few species and with suboptimal support for relationships. Here, we analyze the mode of speciation and causes of species’ range overlap in Neotropical Ruellia (Acanthaceae), a clade of ca. 300 species with many species occurring in sympatry, sometimes even within meters of each other. We use a recently generated well-supported and well-sampled phylogeny in a quantitative framework to test if species sympatry is promoted by one or more factors, including genetic, altitudinal, and/or floral divergence. We also examine the potential for subclade-specific processes.
