Aim  New Zealand broke away from the margins of Gondwana c. 75 Ma. Since then, New Zealand taxa derived from the Gondwanan biota are thought to have been exposed first to a subtropical climate on a low lying terrain, then severe land reduction during the Oligocene marine transgression, followed by much cooler climates of the Pliocene and Pleistocene, at which time mountain ranges emerged. The biological consequence of New Zealand's geological and climatic history is not well understood, in… 

Phylogeography of Australian and New Zealand spray zone spiders (Anyphaenidae: Amaurobioides): Moa's Ark loses a few more passengers

The present study further limits the scope of the Moa's Ark hypothesis of vicariant New Zealand biogeography by showing that Amaurobioides reached Australia approximately 4.5 Mya and dispersed twice to New Zealand.

Good morning Gondwana

Summary Vicariance and dispersion both must be considered as possibilities for the fauna and flora of New Zealand and New Caledonia. Oligocene submersion, promoted by the geologists and several

Evolutionary radiation of the cicada genus Maoricicada Dugdale (Hemiptera: Cicadoidea) and the origins of the New Zealand alpine biota

The reconstructions suggest that the ancestral Maoricicada may have been preadapted to the alpine environment because it existed before the origin of high mountainous habitats, dwelt at mid-to-low altitudes, and yet possessed the classic alpine insect adaptations of heavy pubescence and dark coloration.

Species Radiation of Carabid Beetles (Broscini: Mecodema) in New Zealand

The inferred timings indicate radiation of these beetles no earlier than the mid-Miocene with most divergences being younger, dating to the Plio-Pleistocene, emphasising the youthful and dynamic nature of New Zealand evolution that will be further elucidated with detailed ecological and population genetic analyses.

Genetic divergence of three freshwater isopod species from southern New Zealand

The three New Zealand species of Austridotea are genetically distinct, with up to 31% divergence between species, and divergence was greatest on islands distant from mainland New Zealand and in the discrete Fiordland region.

Genetic divergences pre‐date Pleistocene glacial cycles in the New Zealand speckled skink, Oligosoma infrapunctatum

Aim  To examine the hypothesis raised by Graham S. Hardy that Pleistocene glacial cycles suffice to explain divergence among lineages within the endemic New Zealand speckled skink, Oligosoma

Evolution of New Zealand's terrestrial fauna: a review of molecular evidence

Molecular studies of terrestrial animals and plants in New Zealand indicate that many taxa arrived since isolation of the land, and that diversification in most groups is relatively recent.


An important cladogenetic role for glaciation is indicated, an abiotic evolutionary process that is more typically associated with loss of biodiversity.

New Zealand phylogeography: evolution on a small continent

New Zealand has long been a conundrum to biogeographers, possessing as it does geophysical and biotic features characteristic of both an island and a continent. This schism is reflected in



The Oligocene bottleneck and New Zealand biota: genetic record of a past environmental crisis

The data support the existence of a widespread genetic bottleneck during the mid-Cenozoic in New Zealand and demonstrate the benefits of synthesizing traditional research with new molecular techniques.

A new family of monotremes feom the Creataceous of Australia

With four families now known from Australia, it is probable that monotremes originated and diversified in the Australian/Antarctic sector of Gondwana, followed by a single dispersal to the South American sector before or during the early Paleocene.

Scree weta phylogeography: Surviving glaciation and implications for Pleistocene biogeography in New Zealand

It appears that D. connectens survived across much of the South Island in a mosaic of ecological, rather than one or few, regional refugia, which is likely to relate to the combined effects of mountain‐top isolation during Pleistocene interglacials and ice barriers to dispersal during glacials.

Using molecular methods to understand the Gondwanan affinities of the New Zealand biota: three case studies

The results from three studies carried out recently on parakeets, cicadas and geckos in the context of the Gondwanan affinities of the New Zealand biota are described.

Evolution and distribution of the New Zealand flora, as affected by quaternary climates

From the evidence of endemism and discontinuous distribution, it is concluded that Otago and Southland, Nelson, and South Island plants are adapted to still–existing conditions and Pleistocene glaciation and subsequent climatic amelioration.

A phylogenetic analysis of New Zealand giant and tree weta (Orthoptera : Anostostomatidae : Deinacrida and Hemideina) using morphological and genetic characters

A phylogenetic analysis of New Zealand weta from the sub-family Deinacridinae shows evolution of stridulatory ridges used for sound production in both defence and intraspecific communication appears to have occurred at least twice and adaptation to the recent New Zealand alpine environment has also had multiple origins.

Phylogeny, biogeography and adaptive radiation of Pachycladon (Brassicaceae) in the mountains of South Island, New Zealand

Aim To report analyses and propose hypotheses of adaptive radiation that explain distributional patterns of the alpine genus Pachycladon Hook, closely related to Arabidopsis thaliana.

A new species of tree weta from the North Island of New Zealand (Hemideina: Stenopelmatidae: Orthoptera)

Hemideina trewicki, a new species of Stenopelmatidae from Hawkes Bay, is described and differs from H. crassidens only in the colouration of the pronotum but it can be distinguished using two allozyme loci and the number and gross morphology of the chromosomes.

Mitochondrial DNA phylogeny and sequential colonization of Canary Islands by darkling beetles of the genus Pimelia (Tenebrionidae)

Fifteen species of the darkling beetle genus Pimelia (Tenebrionidae: Coleoptera) have been sequenced for a 365 b. p. portion of the mitochondrial Cytochrome Oxidase I gene. Thirteen of these are

Phylogeographical pattern correlates with Pliocene mountain building in the alpine scree weta (Orthoptera, Anostostomatidae)

A model is proposed to explain this phylogeographical structure, which links the radiation of D. connectens to Pliocene mountain building, and maintenance through the combined effects of mountain‐top isolation during Pleistocene interglacials and ice barriers to dispersal during glacials.
