| comparative host-parasite population genetic structures: obligate fly ectoparasites on galapagos seabirds. | parasites often have shorter generation times and, in some cases, faster mutation rates than their hosts, which can lead to greater population differentiation in the parasite relative to the host. here we present a population genetic study of two ectoparasitic flies, olfersia spinifera and olfersia aenescens compared with their respective bird hosts, great frigatebirds (fregata minor) and nazca boobies (sula granti). olfersia spinifera is the vector of a haemosporidian parasite, haemoproteus iwa ... | 2013 | 23659306 |
