The olive shells (Amalda H. & A. Adams, 1853, Ancillariidae) are marine gastropods largely confined to temperate regions (Olson, 1956) with almost 100 species throughout the Pacific and Atlantic oceans. The highest species diversity is in tropical waters with few species in the southern Pacific (Kantor, Fedosov, Puillandre, Bonillo, & Bouchet, 2017). Amalda generally live in sandy near‐shore envi‐ ronments where they are predators, primarily feeding on bivalves (Powell, 1979). The benthic, soft…

The Indo-Pacific Amalda (Neogastropoda, Olivoidea, Ancillariidae) revisited with molecular data, with special emphasis on New Caledonia

Molecular analysis of 78 specimens from throughout the range of Amalda hilgendorfi shows both a weak geographical structuring and evidence of gene flow at the regional scale, and confirms the validity of the New Caledonia endemics A. aureomarginata, A. fuscolingua, and A.coriolis.

Generation of large mitochondrial and nuclear nucleotide sequences and phylogenetic analyses using high-throughput short-read datasets for endangered Placostylinae snails of the southwest Pacific

Phylogenetic analysis on this large dataset (mitochondrial genome + nuclear markers) supported geographical clustering of species but could not confidently infer monophyly of the four Placostylus species with respect to Eumecostylu cleryi.

Rapid acquisition of microorganisms and microbial genes can help explain punctuated evolution

A complementary explanation for punctuated evolution by the rapid formation of genetic variants in animals and plants by the acquisition of microorganisms from the environment into microbiomes and microbial genes into host genomes by horizontal gene transfer is presented.



Vicars, tramps and assembly of the New Zealand avifauna: a review of molecular phylogenetic evidence

The New Zealand avifauna is neither isolated nor stable, but demonstrative of prolonged and ongoing colonization, speciation and extinction.

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

A phylogeny of Southern Hemisphere whelks (Gastropoda: Buccinulidae) and concordance with the fossil record.


DNA sequences of lecithotrophic monodontine topshells, belonging to the genera Diloma, Melagraphia, and Austrocochlea, are used to ascertain how this group became established over a large area of the South Pacific Ocean and to infer several dispersal events across wide stretches of ocean.

The results support the hypothesis that the two clades of Littorina in the northern Atlantic originated from Pacific ancestors which took part in the Pliocene trans-Arctic migration of marine organisms.

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.

Phylogeny and systematics of mitriform gastropods (Mollusca: Gastropoda: Neogastropoda)

The present study aimed at the reconstruction of phylogenetic relationships of mitriform gastropods based on representative taxon sampling, and recovered Mitridae as a monophyletic group, whereas the genus Mitra was found to be polyphyletic.

Revisiting the insect mitochondrial molecular clock: the mid-Aegean trench calibration.

A well-established biogeographic barrier is used, the mid-Aegean trench separating the western and eastern Aegean archipelago, to estimate substitution rates in tenebrionid beetles, and a divergence rate of 3.54% My(-1) for the cox1 gene was obtained under the preferred partitioning scheme and substitution model selected using Bayes factors.

The ark was full! Constant to declining Cenozoic shallow marine biodiversity on an isolated midlatitude continent

Abstract In recent years several authors have questioned the reality of a widely accepted and apparently large increase in marine biodiversity through the Cenozoic. Here we use collection-level
