    The Australian National Algae Culture Collection (ANACC) is housed at the Hobart laboratories of CSIRO Marine and Atmospheric Research. The collection consists of 1000 strains of more than 300 microalgae species. The collection includes representatives from all classes of marine microalgae, some freshwater microalgae, and unusual marine microheterotrophs. The culture collection specialises in the Australian region, with microalgae from tropical to polar waters, as well as microalgae from around the world. Many Australian strains are genetically and biochemically different from those found elsewhere. Strains include: - nutritionally important microalgae for aquaculture feeds and human health - microalgal biodiversity for biotechnology - ecologically significant microalgae including bloom-forming and toxic strains for environmental management - reference cultures for pigment standards used in oceanography and water quality analyses. Housed in world-class microalgal culture facilities, the collection is a resource for investigations into the growth, physiology, taxonomy, biodiversity, chemistry and molecular genetics of microalgae. The facility specialises in: - isolation and culture of microalgae strains - bacteria-free culture techniques - growth optimisation and manipulation - biomass production - microalgal taxonomy - chemical and biochemical analytical capability - molecular and genetic techniques. The Collection Strain Database is accessible online (see data links).

    This dataset contains the results from surveys of epiphyte fauna from 3 sites along the Perth metropolitan coastline, Western Australia. Samples from Warnbro, Shoalwater and Marmion were collected in September 1993. All sites had the seagrasses Posidonia sinuosa and Amphibolis griffithii within 10 m of each other, and in depths of between 3 m and 6 m. At each site the species abundance and biomass of grazers and epifaunal groups, particularly molluscs and crustaceans were determined. This was to assess their suitability as indicator species in monitoring programs.

    We attempted to asses the potential for using stable isotopes as a tool for rapid assessment of trophic interactions in a nearshore benthic ecosystem in Western Australia. The information gained from this experiment will help us to refine our use of stable isotopes, and contribute to efforts to develop "sharper" tools to achieve the ultimate goal of providing accurate characterisation of food webs, information sorely needed by managers of marine resources. A controlled laboratory scale feeding experiment with the gastropod, Turbo torquatus was conducted to assess the suitability of stable isotope analyses for diet inference. Seventy eight T.torquatus were fed enriched macroalgae (Ulva lactuca) to alter their natural isotopic profile (ä13C and ä15N) and then fed three locally occurring macroalgae (Ulva lactuca, Carpopeltis phyllophora, and Ecklonia radiate) over 17 weeks to assess how their isotopic profile reflected that of their diet. Feeding the enriched macroalgae (Ulva lactuca) to Turbo torquatus increased their carbon and nitrogen isotope ratios to very high levels after just 72 hours. Unfortunately even after 17 weeks of feeding on natural macroalgae (not enriched) the heavier isotope for both carbon and nitrogen was still retained in the muscle tissue of the gastropods. This suggests that the enrichment of Ulva lactuca appears to have been for too long or the concentration of 98% ä13C NaHCO3 and 98% ä15N NH4Cl was much too high.

    Algal biomass in the Perth region were identified from quadrat surveys , as part of the SRFME research program. The aim of the SRFME Coastal project is to characterize the coastal benthic ecosystems of southwestern WA, with particular focus on benthic reef cosystems, their productivity and dynamics, and the physical, chemical and biological factors driving variability along dominant spatial and temporal scales. To achieve this, we undertook 3-monthly seasonal sampling from 2003 - 2005 at a series of coastal sites situated between Cape Naturaliste in the south and Jurien Bay in the north. Benthic Sampling was integrated with satellite observations of SST, ocean colour and subsurface measurements of other water column properties, as well as sediment biogeochemical sampling. Within this region benthic sampling was nested at Regional (100s km) Local (10s km) and Site (1 km) scales and within each of the regions additional sites were sampled to incorporate site scale variability along cross-shore gradients.

    This dataset contains species distribution, abundance and identity data of benthic invertebrates from Batemans Bay, NSW. Epifauna samples from the inter-tidal and subtidal rocky coasts around the bay were sampled twice, in November 1990 and August 1991. The data were taken as a control site for similiar sampling in Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.
