ATT024 to WP029: Antarctic Biogeography Revisited: Updating the Antarctic Conservation Biogeographic Regions

Terauds, Aleks and Lee, Jasmine R., 2016. Antarctic biogeography revisited: updating the Antarctic Conservation Biogeographic Regions. Diversity and Distributions, 1–5.

Abstract:

The Antarctic Conservation Biogeographic Regions (ACBRs), originally pro- posed in 2012, are now established as an important tool in Antarctic science, conservation, management and policy. Here, we provide a revised version of the ACBRs, reflecting updates in underlying spatial layers, together with the results of new analyses justifying the inclusion of a 16th bioregion. This updated version now covers all ice-free areas of Antarctica and is publicly avail- able through the Australian Antarctic Data Centre. In light of the interest in the ACBRs across a variety of research fields, we also provide a new set of sum- mary statistics for the updated spatial layer, including landscape metrics, cli- mate data, protected area coverage and an overview of human activity. The updated ACBRs represent a contemporary, practical and evidence-based foun- dation for understanding, conserving and managing Antarctic biodiversity at a continental scale.

Keywords: Antarctic biodiversity, Antarctic Conservation Biogeographic Regions, biogeo- graphical zones, conservation planning, multivariate analyses, spatial ecology.
