The isolation of the Southern Ocean after the opening of Drake Passage some 23–25 million
years ago, the formation of the Antarctic Circumpolar Current, the subsequent cooling of the …

Heightened interest in the exploitation of deep seafloor minerals is raising questions on the
consequences for the resident fauna. Assessing species ranges and determination of …

Marine benthic biodiversity can be measured using a range of sampling methods, including
benthic sleds or trawls, grabs, and imaging systems, each of which targets a particular …

We summarize and evaluate explanations that have been proposed to account for the
unusually high number of benthic marine invertebrate species in the Southern Ocean with …

However derived, predictions of global marine species diversity rely on existing real data. All
methods, whether based on past rates of species descriptions, on expert opinion, on the …

Abstract Polychaetes in the Southern Ocean are often thought to have wide distribution
ranges on a horizontal and vertical scale. Here, this theory is tested for specimens …

The Ross Sea, Antarctica, is amongst the least human-impacted marine environments, and
the site of the world's largest Marine Protected Area. We present research on two …

Based on a dataset of 16,991 and 307 morphospecies of polychaete worms collected from
58 epibenthic sledge deployments across the Scotia and Amundsen Seas, we show that the …

Latitudinal biodiversity gradients vary across taxonomic groups and spatial scales, and
various environmental factors have been associated with those patterns. However, it …

Simultaneously investigating variation in species richness and turnover for indigenous and
introduced communities holds great promise as a means to understand the relative …
