Multi-scale spatial variation in stable isotope and fatty acid profiles amongst temperate reef species: implications for design and interpretation of trophic studies
This study demonstrates that for the increasing number of trophic studies using combined biochemical tracers, sampling design should cater to the differences in the variability of each tracer technique and allocate sampling accordingly. Expand
Classification and Prediction of Macroinvertebrate Assemblages from Running Waters in Victoria, Australia
P predictive models using 2 macroinvertebrate data sets from bankside habitats at 49 undisturbed reference sites from 6 Victorian river basins showed that the fauna conformed with expectation, and the O/E ratio could thus be considered a sensitive measure of disturbance. Expand
Broad-scale environmental gradients among estuarine benthic macrofaunal assemblages of south-eastern Australia: implications for monitoring estuaries
The present survey did not support the classification of estuarine assemblages on the basis of a range of physical parameters but, instead, emphasised the continuity ofEstuarine benthic macrofaunal community structure on a broad spatial scale. Expand
Influence of taxonomic resolution on multivariate analyses of arthropod and macroalgal reef assemblages
It is found that the impact of taxonomic aggregation varied for faunal and macroalgal assemblages, and that whereas significant cost-savings can be achieved by identifying invertebrate taxa to family with little or no loss of information, the same is not true for Macroalgalassemblages. Expand
Classification of macroinvertebrate communities across drainage basins in Victoria, Australia: consequences of sampling on a broad spatial scale for predictive modelling
Summary 1. Spatial scale may influence the interpretation of environmental gradients that underlie classification and ordination analyses of lotic macroinvertebrate communities. This could haveExpand
Surrogate measures for assessing cryptic faunal biodiversity on macroalgal-dominated subtidal reefs
Two potential surrogates for predicting arthropod faunal biodiversity on rock subtidal reefs were investigated and the best surrogates were related (i.e. nested), subsets of the fauna assemblages such as family-level taxon richness which was found to be a good predictor ofArthropod species richness at independent test sites.

Evidence of abalone (Haliotis rubra) diet from combined fatty acid and stable isotope analyses
Stable isotopes of carbon suggest that brown algae and/detritus are a more important source of carbon than red algae, and chemical tracers are identified as an important contributor to abalone diet. Expand
Linking nitrogen sources utilised by seagrass in a temperate marine embayment to patterns of seagrass change during drought
Reductions in the extent of seagrass Zostera nigricaulis coverage in Port Phillip Bay (PPB), Australia, between 2000 and 2011 coincided with a prolonged period of drought (1997 to 2009) characterizedExpand
Modern estuarine siliceous spiculites, Tasmania, Australia: A non-polar link to Phanerozoic spiculitic cherts
Biosiliceous sedimentary rocks are well known from the geologic record and many are correctly interpreted to have formed in deep-water or cold-water environments. Shallow non-polar spiculites areExpand
