| infection with haemoproteus iwa affects vector movement in a hippoboscid fly--frigatebird system. | haemosporidian parasites, which require both a vertebrate and invertebrate host, are most commonly studied in the life stages occurring in the vertebrate. however, aspects of the vector's behaviour and biology can have profound effects on parasite dynamics. we explored the effects of a haemosporidian parasite, haemoproteus iwa, on a hippoboscid fly vector, olfersia spinifera. olfersia spinifera is an obligate ectoparasite of the great frigatebird, fregata minor, living among bird feathers for al ... | 2014 | 24215498 |
| 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 |
| prevalence of hemoproteus iwa in galapagos great frigatebirds (fregata minor) and their obligate fly ectoparasite (olfersia spinifera). | the prevalence of hemosporidian parasites varies among different host species, geographic locations, habitats, and host life histories, and yet we do not have a firm understanding of the ultimate causes of the variation. seabirds are not typically found infected with hemosporidian parasites; however, frigatebird species have been repeatedly documented with hemoproteus spp. infections. hemoproteus iwa in galapagos great frigatebirds (fregata minor) is vectored by a hippoboscid fly, olfersia spini ... | 2012 | 22509857 |
