Taxonomic status of the brown teal (Anas chlorotis) in Fiordland

Mitochondrial 12S rRNA sequence data were used to examine the taxonomic status of the endemic brown, Auckland Island, and Campbell Island teal. Based on phylogenetic reconstructions using the 12S rRNA data we have found that the Great Barrier Island brown teal, and the Auckland and Campbell Island t...

Description
Summary:Mitochondrial 12S rRNA sequence data were used to examine the taxonomic status of the endemic brown, Auckland Island, and Campbell Island teal. Based on phylogenetic reconstructions using the 12S rRNA data we have found that the Great Barrier Island brown teal, and the Auckland and Campbell Island teals form a discrete clade, to the exclusion of the Fiordland brown teal. All of the Fiordland brown teal sequenced show striking similarity to grey duck and mallard sequences, with which they group. It therefore seems extremely likely that the Fiordland population of brown teal have at sometime in the past hybridised extensively with these invading species. 1.
