Marbled Teal Marmaronetta angustirostris and Cape Teal Anas capensis on the Ounianga Lakes, northern Chad

Lead isotopes and lead shot ingestion in the globally threatened marbled teal (Marmaronetta angustirostris) and white-headed duck (Oxyura leucocephala).

Lead isotope ratios ((206)Pb/(207)Pb and (208)Pb/(207)Pb) and concentrations in the livers and bones of marbled teal and white-headed duck found dead or moribund were determined in order to establish the main lead source in these waterfowl species. Lead concentrations in bone (dry weight) and liver (wet weight) were found to be very high in many of the white-headed ducks (bone: geometric mean=8...

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 teals form a discrete clade, to the exclusion of the Fiordland brown teal. All of the Fiordland br...
