Gene diversity analysis of mitochondrial DNA, microsatellites and allozymes in landlocked Atlantic salmon
This study investigates the patterns of genetic diversity detected in allozymes, mtDNA, and microsatellites, in order to assess their relative efficacy to differentiate sympatric landlocked salmon populations and to estimate changes in genetic diversity between wild and firstgeneration hatchery fish. Overall, the three genetic markers indicated a genetic differentiation between two sympatric po...
متن کاملStability of population structure and genetic diversity across generations assessed by microsatellites among sympatric populations of landlocked Atlantic salmon (Salmo salar L.)
It may often be necessary to perform genetic analyses of temporal replicates to estimate the significance of spatial variation independently from that of temporal variation in order to ensure the reliability of estimates of a defined population structure. Nevertheless, temporal studies of genetic diversity remain scarce in the literature relative to the plethora of empirical studies of populati...
متن کاملMicrosatellite Gene Diversity Analysis in Landlocked Arctic Char from Maine
—Using six microsatellite loci, we characterized the 12 remaining populations of Arctic char Salvelinus alpinus naturally occurring in Maine. More specifically, we challenged the hypotheses based on previous analyses with other markers that (1) Arctic char from Floods Pond (known locally as silver char) represent a distinct evolutionary lineage and (2) all other Arctic char populations from Mai...
متن کاملEndocrine systems in juvenile anadromous and landlocked Atlantic salmon (Salmo salar): seasonal development and seawater acclimation.
The present study compares developmental changes in plasma levels of growth hormone (GH), insulin-like growth factor I (IGF-I) and cortisol, and mRNA levels of their receptors and the prolactin receptor (PRLR) in the gill of anadromous and landlocked Atlantic salmon during the spring parr-smolt transformation (smoltification) period and following four days and one month seawater (SW) acclimatio...
متن کاملSmolting in anadromous and landlocked strains of Atlantic salmon (Salmo salar)
Juvenile Atlantic salmon from a landlocked population (‘Blege’, lake Byglandsfjord, south– central Norway) and an anadromous population (river Vosso, southwestern Norway) were reared in freshwater on simulated natural photoperiod (60j25VN) between December 2000 and June 2001. Fish from the Blege (mean length: 13.4 cm) and Vosso (mean length: 13.9 cm) strains were transferred to seawater tanks i...
