Journal ArticleDOI
Atlantic salmon Salmo salar L., brown trout Salmo trutta L. and Arctic charr Salvelinus alpinus (L.): a review of aspects of their life histories
Anders Klemetsen,Per-Arne Amundsen,J. B. Dempson,Bror Jonsson,Nina Jonsson,Michael F. O'Connell,E. Mortensen +6 more
TL;DR: Various aspects of phenotypic and life-history variation of Atlantic salmon Salmo salar L., brown trout Salmo trutta L., and Arctic charr Salvelinus alpinus are reviewed.
Journal ArticleDOI
Population structure and gene flow reversals in Atlantic salmon (Salmo salar) over contemporary and long‐term temporal scales: effects of population size and life history
TL;DR: It is found that the directionality of migration is affected by the temporal scale over which gene flow is assessed, and the patterns of population structure furthermore vary between different regions and are compatible with demographic and life‐history attributes.
Journal ArticleDOI
Ecological segregation within and among Arctic char morphotypesin Gander Lake, Newfoundland
TL;DR: Study results provide evidence for the contention that sympatric forms of Arctic char in Gander Lake occupy significantly different foraging niches within the lake and suggest ecologically relevant separations within morphotype groupings result in lower resource competition.
Journal ArticleDOI
Age Structure, Changing Demography and Effective Population Size in Atlantic Salmon ( Salmo salar )
TL;DR: Investigation of Ne in Atlantic salmon populations that have undergone changes in demography and population dynamics, applying four different genetic estimators suggests that life history diversity, density-dependent factors, and metapopulation dynamics may all affect the genetic stability of these populations.
Journal ArticleDOI
Mature male parr contribution to the effective size of an anadromous Atlantic salmon (Salmo salar) population over 30 years
TL;DR: Comparisons between genetic and demographic estimates show that the adult spawners inadequately explain the observed Ne estimates, suggesting that mature male parr are significantly increasing Nb and Ne over the study period.
