| dynamics and phylogenetic implications of mtdna control region sequences in new world jays (aves: corvidae). | to study the evolution of mtdna and the intergeneric relationships of new world jays (aves: corvidae), we sequenced the entire mitochondrial dna control region (cr) from 21 species representing all genera of new world jays, an old world jay, crows, and a magpie. using maximum likelihood methods, we found that both the transition/transversion ratio (kappa) and among site rate variation (alpha) were higher in flanking domains i and ii than in the conserved central domain and that the frequency of ... | 2000 | 10948266 |
| molecular systematics and evolution of the cyanocorax jays. | phylogenetic relationships were studied in the genus cyanocorax (aves: corvidae) and related genera, psilorhinus and calocitta, a diverse group of new world jays distributed from the southern united states south to argentina. although the ecology and behavior of some species in the group have been studied extensively, lack of a molecular phylogeny has precluded rigorous interpretations in an evolutionary framework. given the diverse combinations of plumage coloration, size, and morphology, the t ... | 2010 | 19931623 |
