| lineage sorting in multihost parasites: eidmanniella albescens and fregatiella aurifasciata on seabirds from the galapagos islands. | parasites comprise a significant percentage of the biodiversity of the planet and are useful systems to test evolutionary and ecological hypotheses. in this study, we analyze the effect of host species identity and the immediate local species assemblage within mixed species colonies of nesting seabirds on patterns of genetic clustering within two species of multihost ectoparasitic lice. we use three genetic markers (one mitochondrial, coi, and two nuclear, ef1-α and wingless) and maximum likelih ... | 2015 | 26380662 |
