The world's subantarctic islands are rare, ecologically distinct ecosystems with geographical and climahemistic challenges for undertaking emergency response. Their remoteness has somewhat protected them and their flora and fauna from environmental pollution threats and impacts. However, with increasing tourism, fishing, oil and gas exploration and shipping routes, the risk of accidents and petroleum spills has exponentially increased. This review explores the uniqueness of New Zealand's (NZ) subantarctic islands, their oil spill threats and the legislation protecting them. Then using this background information; use the NZ subantarctic islands as examples to understand oiled wildlife response options for subantarctic islands. There are obvious logistical constraints on ability to respond in these remote areas. However, with planning, including preparation of specialised plans, equipment and readiness of skilled response personnel; the conservation outcomes for these ecologically significant, isolated areas, is greater preparedness and protection with the increased ability to respond effectively.

Knowledge of the spatial distribution of many polar seabird species is incomplete due to the remoteness of their breeding locations. Here, we compiled a new database of published and unpublished records of all known snow petrel breeding sites. We quantified local environmental conditions at sites by appending indices of climate and substrate, and regional-scale conditions by appending 30 year mean (1992-2021) sea-ice conditions within accessible foraging areas.

Island and mountain systems represent natural laboratories for studies of species radiations, but they often present several challenges for phylogenetic inference and species delimitation. The southern hemisphere forget-me-nots (Myosotis, Boraginaceae) comprise a geologically recent radiation centred in Aotearoa New Zealand, a mountainous archipelago, with about 50 species that are morphologically and ecologically divergent but lack genetic variation sufficient to resolve phylogenetic relationships and species boundaries using standard DNA Sanger sequencing markers, AFLPs, or microsatellites. Many of these Myosotis species are geographically restricted in alpine areas, uncommon or threatened, have polyploid and dysploid genomes, and are of high taxonomic and conservation priority.

Species distribution models (SDMs) are widely used to address species' responses to bioclimatic conditions in the fields of ecology, biogeography and conservation. Among studies that have addressed reasons for model prediction variability, the impact of climatic variable selection has received limited attention and is rarely assessed in sensitivity analyses. Here, we tested the assumption that this aspect of model design is a major source of uncertainty, especially when projections are made to non-analogue climates.
