Chapter 10 - Phylogenetic Relationships among the Salmoninae Based on Nuclear and Mitochondrial DNA Sequences

Abstract

This chapter highlights the phylogenetic relationships among the Salmoninae based on nuclear and mitochondrial DNA (mtDNA) sequences. Major questions concerning the relationships of the fishes in the subfamily Salmoninae are reviewed and conflicting data are evaluated. It discusses only the North American species because very little molecular data is available on the Russian chars. Intergeneric relationships including taxonomy and status of proposed genera, molecular data on disputed genera, and relationships among genera with their molecular data are explained. It provides a summary of morphological, karyological, and allozyme data with representations for suggested relationships among chars of the genus. A thorough analysis of the conflict between data from mtDNA and nuclear DNA is also provided along with relationships among Taxa in the S. alpinus–S. malma complex species. Some more examples of relationships between different species are provided which cover the morphological data and molecular data from mtDNA Genes and nuclear genes. A table shows comparison of sequence divergence for several nuclear and mitochondrial genes in salmonid fishes.
