| three new species of plagioporus stafford, 1904 from darters (perciformes: percidae), with a redescription of plagioporus boleosomi (pearse, 1924) peters, 1957. | a form of plagioporus stafford, 1904 is described from the intestine of three north american species of darters (perciformes: percidae) from river west twin, wisconsin, usa, that we consider to be conspecific with plagioporus boleosomi (pearse, 1924) peters, 1957 based on similarities in the sucker ratio, extent of the forebody, shape and position of the testes, vitellarium distribution and terminal genitalia. three new species of plagioporus are described from the intestine of darters as follow ... | 2017 | 28130667 |
| new species of plagioporus stafford, 1904 (digenea: opecoelidae) from california, with an amendment of the genus and a phylogeny of freshwater plagioporines of the holarctic. | plagioporus hageli n. sp. is described from the intestine of oncorhynchus mykiss (walbaum) collected from the river yuba, california, usa. of the accepted, nominal species of plagioporus stafford, 1904 from the nearctic, the new species is morphologically similar to three intestinal species from the western usa parasitising diadromous fishes, including plagioporus shawi (mcintosh, 1939), plagioporus kolipinskii tracey, choudhury, cheng & ghosh, 2009 and plagioporus siliculus sinitsin, 1931, and ... | 2016 | 27638729 |
| the life history of plagioporus shawi (mcintosh 1939) (trematoda:opecoelida), an intestinal parasite of salmonid fishes. | podocotyle shawi is transferred to the genus plagioporus. the miracidium develops and hatches in 11 to 14 days at 22 to 25 c. the operculate snail, lithoglyphus virens, serves as first intermediate host. mother and daughter sporocysts develop, the latter producing cotylomicrocercous cercariae within 90 to 130 days. cercariae encyst in the amphipod, hyalella azteca; stonefly nymphs of the genus arcynopteryx; mayfly nymphs of the genera heptagenia and paraleptophlebia; chironomid larvae of the gen ... | 1975 | 1185432 |
| parasite phylogeographical congruence with salmon host evolutionarily significant units: implications for salmon conservation. | comparative phylogeographical studies between parasites and their hosts or with biogeographical regions are useful to predict parasite dispersal potential over a broad geographical range. we used both microsatellite markers and mtdna sequence data from a trematode parasite, plagioporus shawi, to test for congruence across two evolutionarily significant unit (esu) boundaries of its salmonid hosts (oncorhynchus spp.). we find congruent patterns with the nuclear loci of p. shawi and the esu boundar ... | 2007 | 17305856 |
| minimal selfing, few clones, and no among-host genetic structure in a hermaphroditic parasite with asexual larval propagation. | little is known about actual mating systems in natural populations of parasites or about what constitutes the limits of a parasite deme. these parameters are interesting because they affect levels of genetic diversity, opportunities for local adaptation, and other evolutionary processes. we expect that transmission dynamics and the distribution of parasites among hosts should have a large effect on mating systems and demic structure, but currently we have mostly speculation and very few data. fo ... | 2006 | 16637500 |
