| mitochondrial dna variation of gyrodactylus spp (monogenea, gyrodactylidae) populations infecting atlantic salmon, grayling, and rainbow trout in norway and sweden. | approximately 800 bp of the mitochondrial cytochrome oxidase i (coi) gene were sequenced from 76 gyrodactylus specimens of 32 salmonid host populations, i.e. from salmo salar, thymallus thymallus, and oncorhynchus mykiss in norway, sweden and latvia. the coi sequences indicated a substantial intraspecific differentiation of gyrodactylus salaris and gyrodactylus thymalli. in total, 12 haplotypes were identified which group into five well supported clades, three clades with parasites from atlantic ... | 2003 | 14572510 |
| genetic population structure of gyrodactylus thymalli (monogenea) in a large norwegian river system. | the extent of geographic genetic variation is the result of several processes such as mutation, gene flow, selection and drift. processes that structure the populations of parasite species are often directly linked to the processes that influence the host. here, we investigate the genetic population structure of the ectoparasite gyrodactylus thymalli žitňan, 1960 (monogenea) collected from grayling (thymallus thymallus l.) throughout the river glomma, the largest watercourse in norway. parts of ... | 2015 | 26463886 |
