Ecological, morphological, and genetic diversity of burbot (Lota lota L., 1758) in large river basins of Western Siberia

A study has been performed on the ecological, morphological, and genetic diversity of burbot (sample size n = 204 and n = 134, respectively) from eight localities of the Ob–Irtysh and Taz river basins, Western Siberia. Fish differentiation in body size and weight depending on the dominant type of mi...

Description
Summary:A study has been performed on the ecological, morphological, and genetic diversity of burbot (sample size n = 204 and n = 134, respectively) from eight localities of the Ob–Irtysh and Taz river basins, Western Siberia. Fish differentiation in body size and weight depending on the dominant type of migration behavior, foraging conditions, and physiographic features of habitats has been revealed. A high genetic diversity (854-bp mtDNA control region) and a low level of between-sample differentiation is evidence for high intergroup gene flow.
