title: Tracking the origins of the introduced terrestrial amphipod, Puhuruhuru patersoni, on sub-Antarctic Macquarie Island

authors: Parvizi, Elahe

abstract: The terrestrial amphipod Puhuruhuru patersoni (Amphipoda: Talitridae) was discovered on sub-Antarctic Macquarie Island in 1992. The species is only known to naturally occur on New Zealand’s South Island and some associated offshore islands. The possible routes by which the species was introduced to Macquarie Island have previously been considered based on morphology and historic activities between New Zealand and Macquarie Island. Here, we sampled across the known range for P. patersoni and generated mtDNA COI data for these specimens to investigate the likely origin of the Macquarie Island incursion. Our results showed high genetic diversity across the native range and substantially lower genetic diversity on Macquarie Island. Additionally, our phylogenetic reconstructions suggested that the source of the introduction to Macquarie Island is likely to have been from the southern region of New Zealand’s South Island.

title: Balance, cognitive tuning, status and positivity bias in communication of impressions

authors: Armstrong, Warwick David

abstract: Experiment 1 (n=120) was a 3x2x2 analysis of variance design, investigating the interaction of the effect of cognitive tuning, balance and sex on polarization of personality impressions. While balance variables influenced polarization it did not mask the different polarization effects of the cognitive tuning sets, transmission and reception. The checking of positive traits outstriped the checking of negative traits by a factor of 2. 25. Males polarized more than females. Experiment 2 (n=40) investigated the interaction of tuning, sex and status. Status and sex effects on polarization were significantly different on transmission tuning only.

title: Editorial Introduction: The utility and futility of 'the nation' in histories of Aotearoa New Zealand.

authors: Coleborne, Catharine

subjects: New Zealand

abstract: An introduction is presented which discusses articles in the issue on New Zealand history, including one on interracial rape and sexual violence in the 1860s, one on postcolonial methodology and the historical concept of the British World, and one on Whanganui Māori claims to the Whanganui River.
