| mtdna from fossils reveals a radiation of hawaiian geese recently derived from the canada goose (brantacanadensis). | phylogenetic analysis of 1.35 kb of mtdna sequence from fossils revealed a previously unknown radiation of hawaiian geese, of which only one representative remains alive (the endangered hawaiian goose or nene, branta sandvicensis). this radiation is nested phylogenetically within a living species, the canada goose (branta canadensis) and is related most closely to the large-bodied lineage within that species. the barnacle goose (branta leucopsis) is also nested within the canada goose species an ... | 2002 | 11818543 |
