Fish track wastewater pollution to estuaries
TLDR
Fish-δ15N is a suitable indicator of wastewater-N not only in systems that receive large loads, but also for the detection of more subtle nitrogen inputs, and may be preferred indicators of sewage-N contamination. Expand
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. Expand
Soft-sediment benthic community structure in a coral reef lagoon -- the prominence of spatial heterogeneity and 'spot endemism'
TLDR
Focusing on the soft-sediment assemblages within the lagoon of the Great Astrolabe Reef (Fiji), quantified pat- terns, clines and variability of community structure across space and evaluated models for marine bio- diversity conservation based on the spatial distribution and rarity of benthic species. Expand
Accumulation, contamination, and seasonal variability of trace metals in the coastal zone – patterns in a seagrass meadow from the Mediterranean
TLDR
Seasonal cycles in storm frequency and amplitude which remobilise metals bound in the sediments of the sea floor, and increased precipitation during the cold season which may significantly increase marine metal levels through elevated weathering of rocks and elevated fluvial inputs of anthropogenic contaminant loads are suggested. Expand
Differential accumulation patterns of heavy metals among the dominant macrophytes of a Mediterranean seagrass meadow
TLDR
The striking differences in accumulation behaviour exemplified in this study, both among metals and among species, caution against restricting environmental pollution analysis to one or a few ‘indicator’ organisms. Expand
Deep-sea lithistid assemblages from the norfolk ridge (New Caledonia), with description of seven new species and a new genus (Porifera, Demospongiae)
Les monts sous-marins sont frequemment vus en tant que « systemes d'iles » d'eau profonde de biomasse et de richesse extraordinaires, contenant des assemblages de taxa uniques avec un eventailExpand
High-resolution seabed imagery as a tool for biodiversity conservation planning on continental margins
TLDR
This report reports on sponge diversity and bottom cover in three canyons of South-eastern Australia, test the performance of biological and abiotic surrogates, and evaluates how biological data from detailed seabed surveys can be used in conservation planning in these habitats. Expand
Spatial heterogeneity of epibenthos on artificial reefs: fouling communities in the early stages of colonization on an East Australian shipwreck
TLDR
This study quantified spatial heterogeneity in community composition and diversity of fouling communities across a number of environmental gradients that included water depth, surface orientation of habitats, exposure to currents, and shelter, and supported the notion that wrecks enhance local diversity and biomass within the habitat mosaic of their location. Expand
Two new species of Chondrocladia (Demospongiae: Cladorhizidae) with a new spicule type from the deep south Pacific, and a discussion of the genus Meliiderma
TLDR
Two new species of Chondrocladia are described from the deep Pacific, off New Zealand and South Australia, characterized by the presence of a sheath of special spicules along the stalk, for which the new term 'trochirhabd' is coined. Expand
