Submarine canyons are spectacular topographical features that intersect the continen- tal margins of the world's oceans. Canyons comprise unique habitats in terms of complexity, instabil- ity, material processing, and hydrodynamics, and they may support diverse assemblages of larger epibenthos. Yet, quantitative data on the biodiversity of the megabenthos in canyons are scant. Con- sequently, we quantified the diversity of sponges (a key and dominant group of the megabenthos) in 5 canyons… Expand
Megabenthic biodiversity in two contrasting submarine canyons on Australia's southern continental margin
Abstract Submarine canyons are known to play an important role in enhancing productivity in adjacent surface waters, but their influence on the seabed fauna is poorly understood. Here we examineExpand
Biodiversity and distribution of meiofauna in the Gioia, Petrace and Dohrn Canyons (Tyrrhenian Sea)
Abstract Habitat heterogeneity is a major structuring agent of benthic assemblages promoting high turnover in species composition and ultimately contributing to overall higher diversity. SubmarineExpand
Biodiversity of suprabenthic peracarid assemblages from the Blanes Canyon region (NW Mediterranean Sea) in relation to natural disturbance and trawling pressure
Abstract Blanes Canyon and its adjacent margin are important fishery areas (mainly by bottom trawling) located in a highly energetic oceanographic setting in the NW Mediterranean Sea. Here we assessExpand
Scales of habitat heterogeneity and megabenthos biodiversity on an extensive Australian continental margin (100–1100 m depths)
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.

Living on the edge: the sponge fauna of Australia’s southwestern and northwestern deep continental margin
This first assessment of sponges on Australia’s deep western continental margin found that highly species-rich sponge assemblages dominate the megabenthic invertebrate biomass in both southwestern and northwestern areas, suggesting depth-related factors, substrate type, and current regimes are the most influential.

Coral habitats in submarine canyons of the Bay of Biscay : distribution, ecology and vulnerability
Cold-water coral (CWC) habitats formed by colonial scleractinians, gorgonians, antipatharians and sea pens are biodiversity and biomass hotspots that provide important functions, such as shelter andExpand
Megabenthic diversity patterns and community structure of the Blanes submarine canyon and adjacent slope in the Northwestern Mediterranean: a human overprint?
The composition and structure of megabenthic communities in the Blanes canyon and adjacent open margin (Northwestern Mediterranean) were studied. The aim was to assess the effect of the canyon andExpand
Changes in deep-water epibenthic megafaunal assemblages in relation to seabed slope on the Nigerian margin
Local-scale habitat heterogeneity associated with changes in slope is a ubiquitous feature of bathyal continental margins. The response of deep-sea species to high habitat heterogeneity is poorlyExpand
Slope-shelf faunal link and unreported diversity off Nova Scotia: Evidence from polychaete data
Abstract Deep-water sedimentary habitats off Nova Scotia have only rarely been explored. The topographically and oceanographically complex shelf of Nova Scotia harbours two interesting topographicExpand
Outcropping reef ledges drive patterns of epibenthic assemblage diversity on cross-shelf habitats
This study quantified the diversity of morphotype classes on an outcropping reef system characteristic of the continental shelf margin in the Flinders Commonwealth Marine Reserve, southeastern Australia and highlights the particular importance of outcropped reef ledge features in this region, as they provide a refuge against sediment scouring and inundation common on the low profile reef that characterizes this region.

Macrofaunal communities within and adjacent to a detritus-rich submarine canyon system
Abstract Macrofaunal abundance, biomass, diversity and species assemblages within Scripps and La Jolla Submarine Canyons are compared with those on the nearby continental shelf and slope. Our primaryExpand
Deep-water decapod crustacean communities in the Northwestern Mediterranean: influence of submarine canyons and season
There were seasonal variations, with higher densities of mesopelagic species in spring, which were probably related, among other factors, to variations in the photoperiod, together with seasonal changes in the megafaunal biomass. Expand
Distribution and species composition of mass occurrences of large-sized sponges in the northeast Atlantic
Abstract The geographic and bathymetric distribution of “ostur”, that is mass occurrences of large-sized astrophorid demosponges, first recognized at the Faroe Islands during the internordic BIOFARExpand
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
Observations on bottom currents and epibenthic populations in Hatteras submarine canyon
Abstract Bottom currents and populations of large epifauna were surveyed using bottom photography in the Pamlico axis of the Hatteras Submarine Canyon system. Most species known to be numericallyExpand
The influenceof hexactinellid sponge (Pheronema carpenteri) spicules on the patchy distribution of macrobenthos in the porcupine seabight (bathyal ne atlantic)
Analysis of data on the abundance and taxonomic composition of major groups of the larger (> 1 mm) macrobenthos suggests that the presence of sediment surface sponge spicule mats substantially modifies the fauna at the 1250 m station. Expand
Marine sponges of the Dampier Archipelago, Western Australia: patterns of species distributions, abundance and diversity
The number of species found at only one location was high, supporting previous findings that northwestern Australia has high sponge endemism, andEstimations of diversity based on non-parametric modelling suggests that there are potentially more species than presently recorded in the archipelago.

Small-scale patterns of sponge biodiversity (Porifera) on Sunshine Coast reefs, eastern Australia
Ten reefs off the Sunshine Coast, south-eastern Queensland, were sampled from 1991 to 2000 and were found to contain a rich fauna of 247 species of marine sponges (Porifera) in 97 genera, 44 families and 14 orders, representing a highly unique fauna in this biogeographic transition zone between the Solanderian and Peronian provinces.

Assessing the magnitude of species richness in tropical marine environments: exceptionally high numbers of molluscs at a New Caledonia site
A massive collecting effort involving 400 day-persons at 42 discrete stations on a 295-km2 site on the west coast of New Caledonia, south-west Pacific, revealed 2738 species of marine molluscs, several times the number of species recorded from any area of comparable extension anywhere in the world.
