The impacts of deep-sea fisheries on benthic communities: a review
Deep-sea fisheries operate globally throughout the world's oceans, chiefly targeting stocks on the upper and mid-continental slope and offshore seamounts. Major commercial fisheries occur, or haveExpand
Richness and distribution of sponge megabenthos in continental margin canyons off southeastern Australia
TLDR
A broad comparison with other abrupt topographical features in the bathyal zone of the region suggests that canyon assemblages may rival the diversity of sponges on seamounts, and site-to-site variation in diversity and species composition within individual canyons may be finer-grained than the spatial scale of conventional geomorpho- logical units. Expand
Impacts of bottom trawling on deep-coral ecosystems of seamounts are long-lasting
TLDR
Differences in community structure in the trawled and untrawled seamounts were attributed to resistant species that survived initial impacts, others protected in natural refugia and early colonisers, and long-term persistence of trawling impacts on deep-water corals is consistent with their biological traits that make them particularly vulnerable.

Diets and trophic guilds of demersal fishes of the south-eastern Australian shelf
TLDR
Analysis of stomach samples from 102 fish species caught by trawl or gillnet during research surveys on the south-eastern Australian shelf found that although fish was more important than invertebrate prey, there was no evidence of significant predation on commercially important species (quota species) by other fish species. Expand
Seamount megabenthic assemblages fail to recover from trawling impacts.
TLDR
Network of spatial closures that include intact habitats over a range of depths, especially <1500 m, and on clusters and isolated seamounts, may be effective by maintaining the resilience of seamount benthic communities. Expand
Australia’s deep-water reserve network: implications of false homogeneity for classifying abiotic surrogates of biodiversity
Williams, A., Bax, N. J., Kloser, R. J., Althaus, F., Barker, B., and Keith G. 2009. Australia’s deep-water reserve network: implications of false homogeneity for classifying abiotic surrogates ofExpand
A test of the seamount oasis hypothesis: seamounts support higher epibenthic megafaunal biomass than adjacent slopes
Seamounts have often been viewed as specialized habitats that support unique communities; this notion has given rise to several hypotheses about how seamount ecosystems are structured. One, theExpand
Scales of habitat heterogeneity and megabenthos biodiversity on an extensive Australian continental margin (100–1100 m depths)
TLDR
The first large systematic collection of benthic invertebrate megafaunal communities from the Australian continental margin revealed high species richness and novelty on the south-western continental slope; a key aim is to ensure that a National Representative System of Marine Protected Areas (NRSMPA) will meet the requirement of comprehensiveness, adequacy and representativeness.

A Standardised Vocabulary for Identifying Benthic Biota and Substrata from Underwater Imagery: The CATAMI Classification Scheme
TLDR
The CATAMI classification scheme is presented, its conception and features are described, its utility and the opportunities as well as challenges arising from its use are discussed, to facilitate broad-scale multidisciplinary studies of marine ecosystems when applied globally. Expand
Are deep-sea demersal fish assemblages globally homogenous? Insights from seamounts
Deep-sea fishes have been poorly sampled globally, and overall knowledge of demersal fish distributions and the drivers of community composition and diversity remain limited. Here, we used nineExpand
