Biochemical characterization of the Arctic char (Salvelinus alpinus) ovarian progestin membrane receptor
Membrane progestin receptors are involved in oocyte maturation in teleosts. However, the maturation-inducing steroid (MIS) does not appear to be conserved among species and several progestins may fulfill this function. So far, complete biochemical characterization has only been performed on a few species. In the present study we have characterized the membrane progestin receptor in Arctic char ...
متن کاملTrophic biology and migratory patterns of sympatric Dolly Varden (Salvelinus malma) and Arctic char (Salvelinus alpinus)
The trophic ecology (diet and headmorphology) andmigration patterns of two closely related salmonid fishes, Arctic char (Salvelinus alpinus (L., 1758)) and Dolly Varden (Salvelinus malma (Walbaum, 1792)), were examined in tributaries of Lake Aleknagik, southwestern Alaska, to test for differentiation between species. Schoener’s index of proportional overlap andmultivariate analyses of diets sug...
متن کاملMicrosatellite gene diversity analysis in anadromous arctic char, Salvelinus alpinus, from Labrador, Canada
We analysed six loci among 257 Arctic char (Salvelinus alpinus) representing seven locations in Labrador and Newfoundland to provide a first assessment of microsatellites gene diversity in anadromous char and to determine the geographic scale of population structuring within the species. The number of alleles per locus varied between 9 and 48, and gene diversity ranged from 0.190 to 0.968. Sign...
متن کاملThe fate of chiral organochlorine compounds and selected metabolites in intraperitoneally exposed arctic char (Salvelinus alpinus).
The fate of chiral organochlorine compounds (OCs) and selected metabolites in exposed Arctic char (Salvelinus alpinus) was investigated. The contaminants alpha-hexachlorocyclohexane (alpha-HCH), cis-chlordane, 13C4-heptachlor, o,p'-DDT, and the atropisomeric chlorinated biphenyls (CBs) 95, 132, 136, 149, and 174 were solved in peanut oil and injected into the peritoneal cavity. The exposed fish...
