چکیده

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.

Examination of the helminth communities in 25 yellow-billed ducks (Anas undulata), 21 red-billed ducks (Anas erythrorhyncha), ten Cape teal (Anas capensis) and seven Cape shovellers (Anas smithii) that had overwintered at Barberspan, revealed differences in community structure. Infracommunities in yellow-billed and red-billed ducks were characterized by low diversity and high eveness, and gener...

Impacts of introduced mammalian predators on indigenous birds of freshwater wetlands in New Zealand

The impacts of introduced mammalian predators on the viability of bird populations in forest, river and coastal habitats in New Zealand are well known. However, a common understanding of their impacts in freshwater wetlands is lacking. We review evidence for impacts of introduced mammalian predators on freshwater birds, particularly specialist species restricted to wetlands, and use this inform...
