| molecular faunistics of accidental infections of gyrodactylus nordmann, 1832 (monogenea) parasitic on salmon salmo salar l. and brown trout salmo trutta l. in nw russia. | salmon salmo salar l. and brown trout s. trutta l. juveniles were examined for the presence of accidental monogenean ectoparasitic species of gyrodactylus nordmann, 1832 in the baltic and white sea basins of russian karelia in order to estimate the frequency of host-switching attempts on an ecological timescale. to collect phylogeographical information and for exact species identification, the parasites were characterised by nuclear internal transcribed spacer sequences of rdna (its) and, for so ... | 2008 | 18038199 |
