Journal ArticleDOI
Have the Harmful Effects of Introduced Rats on Islands been Exaggerated
TL;DR: New Zealand is used as a case study because of its four-decade history of rat eradications and many detailed and innovative studies of how rats affect native species, including use of exclosures, local manipulations of rat populations, video surveillance, and measurements of responses following eradications.
Journal ArticleDOI
Neglected taxonomy and continuing extinctions of tuatara (Sphenodon)
TL;DR: The pattern of genetic and morphological differentiation reported here supports a taxonomy dating from 1877 that identified two extant species, one subsequently separated into two subspecies, and warrants increased conserving attention for the single populations of S. guntheri and S. reischeki.
Journal ArticleDOI
Patterns of range contractions and extinctions in the New Zealand herpetofauna following human colonisation
TL;DR: Evidence from subfossils and from present distributions confirming range contractions and extinctions of New Zealand amphibians and reptiles is consistent with that from New Zealand landbirds, in which 40% of the fauna has become extinct in the 1000 years since human arrival.
Journal ArticleDOI
Mega-island or micro-continent? New Zealand and its fauna.
TL;DR: The terrestrial New Zealand fauna has developed on an ancient landmass of continental origins that has had an increasingly isolated existence since the late Mesozoic, characterized by frequent niche shifts, gigantism, and extended life histories with low reproductive rates.
Journal ArticleDOI
Flightless brown kiwis of New Zealand possess extremely subdivided population structure and cryptic species like small mammals.
TL;DR: Using allozymes and mtDNA sequences from the cytochrome b gene, it is reported that the brown kiwi has the highest levels of genetic structuring observed in birds, and Shared-derived morphological characters support the same relationships evident in the molecular phylogenies and suggest that as Brown kiwis colonized northward from the southern South Island, they retained many primitive characters that confounded earlier systematists.
