Many salmonids have been exposed to this pressure over a comparatively short period, particularly in cases where landlocking has occurred as a result of glaciation.

Within the non-aulopiform and non-stomiiform taxa examined in the present work there were effectively some specimens that appeared to have a 'precervical gap', although this gap was not as peculiarly large as that found in the specimens examined of the genera Aulopus, Chlorophthalmus, Astronesthes and Stomias.
All cytochromes analyses indicated that the Pacific salmon formed a paraphyletic group, due to a weak association between the Oncorhynchus kisutch and Oncorhynchus tshawytscha clade with Pacific trout Oncorhynchus clarkii and Oncorhynchus mykiss.
Outgroups were delimited based on recent molecular hypotheses, and consisted of four taxa: superfamily Alepocephaloidea represented by Alepocephalus tenebrosus Gilbert 1892superfamily Argentinoidea represented by Nansenia ardesiaca Jordan and Thompson 1914 ; sub-order Osmeroidei represented by Galaxias maculatus Jenys 1842 ; and order Esociformes represented by Esox lucius Linnaeus 1758 and Dallia pectoralis Bean 1880.
Another point of contention is the relationship between the coregonine genera Coregonus and Stenodus. Introduction The evolutionary relationships among salmonid fishes have been the focus of extensive systematic and phylogenetic research for many decades —. Thys van den Audenaerde, D. Radchenko OA 2004 Introgressive hybridization of chars of the genus Salvelinus as inferred from mitochondrial DNA variation.
Based on morphological evidence, it has been suggested that Coregoninae is the sister group to the remainder of Salmonidae, a finding that is corroborated by recent molecular investigation of some species of Salmonidae using nearly complete mitochondrial sequence data. Some specimens of Mormyrus exhibit CS-0, while others display CS-1 With particular reference to the grayling (Thymallus arcticus) and its phylogeny, 1972; this study ; this genus is thus coded as '? Peculiar, large 'auditory foramen', which is usually an ovoid opening on the ventral face of the prootic through which the utricular otolith is visible.
Results A total of 107 DNA or tissue samples belonging to 63 salmonid species were obtained from a number of people and groups. Rooting Salmonidae To determine the root of the Salmonidae phylogenetic tree, different species were alternatively used as outgroups using a Bayesian approach.

For instance, the divergence rates for Oncorhynchus stated above were double those for Coregonus, which ranged between 0.

huntsmani are very limited, however including this taxon in future datasets will be critical for conclusively testing the monophyly of Coregonus and its relationship with Stenodus.
