Identifying intraspecific units or stocks of a species with unique morphological characteristics
has now become more powerful and enables a better management of these subunits of …

Lake charr, Salvelinus namaycush, ecological and phenotypic diversity within and among
populations was reviewed from empirical and conceptual perspectives. The species is …

Repeated adaptive ecological diversification has commonly been reported in fish and has
often been associated with trophic niche diversity. The main goal of this study was to …

Polymorphism in northern fishes is common, but the extent to which polymorphism occurs in
Lake Trout Salvelinus namaycush, a species generally associated with low intraspecific …

Hybridization can generate novel phenotypes, and in combination with divergent selection
along environmental gradients, can play a driving role in phenotypic diversification. This …

Among fishes, salmonids (family Salmonidae) have attracted a great deal of research
attention focused on sexual dimorphism and associated selective forces. Most of this …

Morphological status of the Mesopotamian spiny eel, Mastacembelus mastacembelus,
populations from Karakay Reservoir, Tohma Stream and Tigris River were investigated …

Abstract Great Bear Lake is the most northerly lake of its size and provides unique
opportunities for intraspecific diversification. Despite increasing attention to intraspecific …

All examples of lake charr (Salvelinus namaycush) diversity occur within the largest, deepest
lakes of North America (ie> 2000 km2). We report here Rush Lake (1.3 km2) as the first …

Weight–Body Length relationships (WLR) of 45 fish species (37 Actinopterygii and eight
Elasmobranchii) were investigated. A total of 31,167 individuals were caught and their …
