Maximum-likelihood phylogenetic tree of nine salmonid species (foreground taxa Coregonus and Salvelinus in red) and outgroup northern pike (Esox lucius; in blue). Node support values are bootstrap values from 1000 bootstrap replications. Branch lengths correspond to the number of substitutions per site. All pictures used here are under public domain. Coregonus and Salvelinus are two genera with exceptional ability for repeated, rapid diversification into ecomorphs within lakes that is unmatched in other salmonid taxa [2, 43,44,45,46,47]
