Ancient DNA Analyses Reveal Contrasting Phylogeographic Patterns amongst Kiwi (Apteryx spp.) and a Recently Extinct Lineage of Spotted Kiwi
The little spotted kiwi (Apteryx owenii) is a flightless ratite formerly found throughout New Zealand but now greatly reduced in distribution. Previous phylogeographic studies of the related brown kiwi (A. mantelli, A. rowi and A. australis), with which little spotted kiwi was once sympatric, revealed extremely high levels of genetic structuring, with mitochondrial DNA haplotypes often restrict...
متن کاملGenetic variation, systematics and management of kiwi (Apteryx spp.)
Kiwi (Apteryx: Struthioniformes) are a family of ratite birds confined entirely to New Zealand. Since 1813, at least ten species have been described. Recent taxonomy has accepted three species: A. owenii (little spotted kiwi), A. haastii (great spotted kiwi) and A. australis (brown kiwi). Apteryx australis has three subspecies: A. a. australis (South Island); A. a. mantelli (North Island); and ...
متن کاملIncubation behaviour and egg physiology of kiwi (Apteryx spp.) in natural habitats
Incubation behaviour varies among the different taxa of kiwi. For North Island brown kiwi (Apteryx mantelli) and little spotted kiwi (A. owenii), only the male incubates the eggs, except for in the first week. Meanwhile, for Okarito brown kiwi (A. mantelli) and the tokoeka (A. australis), incubation is shared by both sexes. In addition, amongst southern tokoeka, family group members can assist ...
متن کاملExperimental management of Brown Kiwi Apteryx mantelli in central Northland, New Zealand
The population growth of Brown Kiwi Apteryx mantelli was measured under four different management regimes: unmanaged, predator trapping, predator poisoning, and Bank of New Zealand Operation Nest Egg (BNZONE) — the removal of eggs for artificial incubation and return of resultant subadults to the wild. Life table analysis revealed that high adult mortality (7.3% per annum), caused mainly by dom...
متن کاملMovement of North Island Brown Kiwi (apteryx Australis Mantelli) between Forest Remnants
Twenty-three kiwi were radio-tracked for 16-116 weeks in a Northland reserve. Eighty-three percent of the kiwi made use of the numerous forest remnants scattered over farmland outside the reserve. All remnants isolated by up to 80 m of pasture were used by kiwi. The maximum distance kiwi walked between forest remnants was 330 m. Longer migrations of up to 1.2 km from the reserve were made by ki...
