Recent extinctions among Little Spotted Kiwi (Apteryx owenii) and the origin of extant populations

چکیده
Little Spotted Kiwi (LSK; Apteryx owenii) have the lowest genetic diversity of five currently recognised kiwi species apparently due to a bottleneck when at most individuals were translocated ...

Genetic consequences of a century of protection: serial founder events and survival of the little spotted kiwi (Apteryx owenii).
We present the outcome of a century of post-bottleneck isolation of a long-lived species, the little spotted kiwi (Apteryx owenii, LSK) and demonstrate that profound genetic consequences can result from protecting few individuals in isolation. LSK were saved from extinction by translocation of five birds from South Island, New Zealand to Kapiti Island 100 years ago. The Kapiti population now nu...
متن کاملComparison of little spotted kiwi (Aptrix owenii) from Kapiti and D'Urvill Islands
The Kapiti and D’Urville Islands populations of little spotted kiwi (Apteryx owenii) are the only two long-standing populations of this species that have survived the decline of kiwi in the 20th century. The populations were compared to determine their conservation status and to provide a basis for management decisions for the two surviving birds from D’Urville Island. Measurements, voice, ecto...
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 کاملAncient 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...
