Ecological risk assessment for the effects of fishing
Management of fisheries around the world is challenged by fishing impacts on habitats, bycatch species, threatened and endangered species, and even associated ecological communities. One response toExpand
Seamount benthic macrofauna off southern tasmania: community structure and impacts of trawling
The benthic macrofauna of a group of small seamounts south of Tasmania was surveyed with a dredge and camera to assess the impact of trawling for orange roughy (Hoplostethus atlanti- cus;Expand
The ecology of seamounts: structure, function, and human impacts.
In this review of seamount ecology, we address a number of key scientific issues concerning the structure and function of benthic communities, human impacts, and seamount management and conservation.Expand
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
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.

Impacts of bottom trawling on deep-coral ecosystems of seamounts are long-lasting
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.

Effectiveness of Biological Surrogates for Predicting Patterns of Marine Biodiversity: A Global Meta-Analysis
This study provides a benchmark for the reliable use of biological surrogates in marine ecosystems, and highlights directions for future development of biological surrogate effectiveness in predicting biodiversity. Expand
Diets and trophic guilds of demersal fishes of the south-eastern Australian shelf
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.

A hierarchical framework for classifying seabed biodiversity with application to planning and managing Australia’s marine biological resources
A conceptual hierarchical framework for classifying marine biodiversity on the sea floor, used successfully for continental-scale bioregionalisation and adopted to guide marine resource planning andExpand
Out of Their Depth? Isolated Deep Populations of the Cosmopolitan Coral Desmophyllum dianthus May Be Highly Vulnerable to Environmental Change
The apparent absence of vertical larval dispersal suggests deep populations of D. dianthus are unlikely to colonise shallow water as the aragonite saturation horizon rises and deep waters become uninhabitable, and future environmental management strategies must consider both regional and depth-related isolation of deep-sea coral populations.
