PCB concentrations in lake trout (Salvelinus namaycush) are correlated to habitat use and lake characteristics.
This study considers the importance of lake trout habitat as a factor determining persistent organochlorine (OC) concentration. Lake trout is a stenothermal, cold water species and sensitive to hypoxia. Thus, factors such as lake depth, thermal stratification, and phosphorus enrichment may determine not only which lakes can support lake trout but may also influence among-lake variability in lak...
متن کاملOvarian fluid influences sperm performance in lake trout, Salvelinus namaycush.
The objectives of this study were to determine whether (i) the presence and concentration of ovarian fluid (OF) affects sperm performance traits, and (ii) variation in sperm performance traits is due to male identity, female identity, and/or male×female interactions in lake trout, Salvelinus namaycush. Spermatozoa from four males were activated in river water and OF from four females at two con...
متن کاملTwelve microsatellite loci for lake trout (Salvelinus namaycush).
We describe 12 microsatellite loci isolated from lake trout (Salvelinus namaycush). The number of alleles at these loci ranged from two to 11 with an average of 5.3 alleles per locus. The expected heterozygosity ranged from 0.29 to 0.76, with an average of 0.68. Accidental (or illegal) introductions of lake trout into watersheds are decimating native trout populations in the northern Rocky Moun...
متن کاملPopulation structure of lake trout (Salvelinus namaycush) in a large glacial-fed lake inferred from microsatellite DNA and morphological analysis
Understanding the structure of intraspecific genetic and morphological diversity within and across habitats is a fundamental aspect of biodiversity research with conservation value. Atlin Lake is the largest lake in British Columbia, Canada, and contains relatively pristine populations of lake trout (Salvelinus namaycush) that are key components of the lake’s fish community and local fisheries....
متن کاملEffects of crystal structure on the uptake of metals by lake trout (Salvelinus namaycush) otoliths
This is the first study to report spectroscopic and elemental analysis of aragonite and vaterite growing simultaneously and separately in both the core and the edges of the same otolith. Our investigations focused on understanding differential trace metal uptake, including the influence of the metal itself (i.e., ionic radii), the crystalline structure, and the development state of the fish. Ch...
