| are phenotypic traits useful for differentiating among a priori coregonus taxa? | a key for three putative species apparently found in three geographic areas, i.e. coregonus clupeoides (in scotland), coregonus stigmaticus (in england), and coregonus pennantii (in wales) given in a recent review was tested quantitatively using 544 individuals from nine populations. the classification success of the key was very low (27%). it was concluded that there is currently no robust evidence for the recognition of the three putative species. furthermore, the use of phenotypic characters ... | 2012 | 22268437 |
| inter and intra-population phenotypic and genotypic structuring in the european whitefish coregonus lavaretus, a rare freshwater fish in scotland. | this study revealed between-lake genetic structuring between coregonus lavaretus collected from the only two native populations of this species in scotland, u.k. (lochs eck and lomond) evidenced by the existence of private alleles (12 in lomond and four in eck) and significant genetic differentiation (fst = 0·056) across 10 microsatellite markers. juvenile c. lavaretus originating from eggs collected from the two lakes and reared in a common-garden experiment showed clear phenotypic differences ... | 2016 | 26748995 |
| histopathology, ultrastructure and immunohistochemistry of coregonus lavaretus hearts naturally infected with ichthyocotylurus erraticus (trematoda). | histopathological, ultrastructural and immunohistochemical investigations were conducted on 26 specimens of powan coregonus lavaretus (l.) from loch lomond (scotland). the hearts of all 26 powan (15 females and 11 males) investigated harboured metacercariae of the digenean trematode ichthyocotylurus erraticus (rudolphi, 1809). the vast majority of metacercariae were located either singly or as an aggregation of white cysts on the surface of the bulbus arteriosus. the intensity of infection range ... | 2005 | 16261940 |
