Phylogeography of the genus Epiplatys (Aplocheiloidea: Cyprinodontiformes).

摘要: There are six major genera of aplocheiloid killifishes endemic to West Africa. Five these largely restricted the two blocks rainforest. Two found within Eastern rainforest block (Nigeria central Congo) while three Western (Sierra Leone Togo). The sixth genus (Epiplatys) has a range that exceeds combined area other five genera. Phylogenetically this is related taxa. Phylogeographic analysis suggests it escaped confines by first expanding into lowland habitats exposed after sea level drop and then dispersed along coastal east. One lineage managed penetrate interior one derivative penetrated Congo basin. A second route out was north through what now savannah habitat. greater phylogeographic Epiplatys hypothesized be due retention ancestral morphology adaptability compared
