Available in PDF, EPUB and Kindle. Book excerpt: This study consists of two sections aimed at investigating the evolutionary history of two groups of : (1) molecular systematics of the cichlid genus Vieja, and (2) phylogeography of the Mountain Mullet, Agonostomus monticola. Results from these studies shed light on the importance of taxon sampling when investigating phylogenetic relationships among closely related groups of fishes and subsequent taxonomic revisions. Results also illustrate the importance of incorporating the complex geological history of Middle America into understanding the evolutionary history of the trans-isthmian species. [Partial Abstract].
