| phylogeny of tetraoninae and other galliform birds using mitochondrial 12s and nd2 genes. | the avian subfamily tetraoninae (grouse and ptarmigan) is a holarctic group in the order galliformes distinguished by morphological adaptations to cold environments and behavioral traits associated with elaborate courtship. here we investigate the relationships of 17 tetraonines and 12 other galliform species using mitochondrial 12s and nd2 sequence data. we found support for the recent phylogenetic classification that separates the genus dendragapus into two genera, falcipennis and dendragapus. ... | 2002 | 12144757 |
