Repeatedly and recently evolved sympatric morphs exhibiting consistent phenotypic
differences provide natural experimental replicates of speciation. Because such morphs are …

Abstract The Arctic char (Salvelinus alpinus) species “complex” has fascinated biologists for
decades particularly with respect to how many species there are and their geographic …

Phylogenetic studies focusing on Salmonidae have revealed significant obstacles in trying
to clarify some interspecific relationships within the Salmoninae subfamily, due to a limited …

Salmonid fishes may reside within or migrate between stream and lake habitats, or undergo
anadromous migrations between freshwater and the ocean. While the degree of anadromy …

Hybridization and introgression are very common among freshwater fishes due to the
dynamic nature of hydrological landscapes. Cyclic patterns of allopatry and secondary …

Natural interspecific hybridization might be more important for the evolutionary history and
speciation of animals than previously thought, considering several demographic and life …

Hybridization between divergent lineages can result in losses of distinct evolutionary taxa.
Alternatively, hybridization can lead to increased genetic variability that may fuel local …

The salmon family is one of the most iconic and economically important fish families,
primarily possessing meat of excellent taste as well as irreplaceable nutritional and …

Arctic char (Salvelinus alpinus) and Dolly Varden (S. malma) are two closely related species
in the genus Salvelinus. Both species show substantial intra-specific variation in ecology …

Six postglacial lakes were studied along both sides of the Kamchatka central mountain
range, Russia. Pairs of local morphotypes of species of Arctic charrs, Salvelinus spp., have …
