• Distribution and abundance of large invertebrate herbivores in south-western Australia, and their potential links to local and regional processes

  Australian Ocean Data Network (AODN)

  A three-pronged approach was taken to quantify patterns of abundance and coexistance at small (centimetres) to very large (hundreds of kilometres) spatial scales. This was through a 'spatio-temporal survey' (tested hypotheses about spatial and temporal…

• Endofauna differences between two temperate marine sponges from southwest Australia

  Australian Ocean Data Network (AODN)

  The endofaunal assemblages associated with two species of sponge from the family Chalinidae (Haliclona sp. 1 and Haliclona sp. 2) were studied at four locations (Bremer Bay, Hamelin Bay, Rottnest Island, and Jurien Bay) during the Australian summer…

• The Ecology of Cockburn Sound Report - Series Summary

  Australian Ocean Data Network (AODN)

  A report was conducted for the Fremantle Port Authority by Environmental Resources of Australia on the Ecology of Cockburn Sound. This report contained data on seagrass width and length, seagrass regrowth and presence/absence of algal epiphytes on seagrass…

• Isopod borers in seagrass species from south-western Australia

  Australian Ocean Data Network (AODN)

  The presence of a number of species of isopod borers (Limnoriidae family) in seagrass species from south-western Australia were documented from sampling seagrass tissue from Rottnest Island. The abundance of isopods within seagrass meadows at Rottnest Island…

• Efficiently measuring complex sessile epibenthic organisms using a novel photogrammetric technique

  Australian Ocean Data Network (AODN)

  This paper describes a stereo photogrammetry method that allows accurate measurements of volume for sessile epibenthic organisms. It represents a novel approach based on multiple views (five stereo image pairs) from a purpose built stereo digital still camera…

• Cockburn Cement - Success Bank - Seagrass and Sand Invertebrates - 1990's

  Australian Ocean Data Network (AODN)

  Invertebrates (epifauna & infauna) from seagrass (Amphibolis griffithii, Posidonia coriacea, Heterozostera tasmanica) and adjacent sand habitats on Success Bank (5-7 m) and deep water (12 m) in Owen Anchorage and Gage Roads were collected at three locations,…

• Biogeochemical constraints on the growth and nutrition of the seagrass Halophila ovalis in the Swan River Estuary - Summary

  Australian Ocean Data Network (AODN)

  Below-ground interactions between biotic and abiotic factors that influence seagrass nutrition and growth were studied, with a focus on Halophila ovalis from the Swan River Estuary, Western Australia between 2003 and 2006.

• The influence of reef structure on the patterns and processes of Ecklonia radiata (C. Agardh) kelp beds of Hamelin Bay, Western Australia

  Australian Ocean Data Network (AODN)

  The physical variables of light, water motion, reef slope and water depth were measured on topographically simple and complex reefs. These physical variables were linked to patterns in the distribution of algae over the two reef types using DISTLM, a…

• Limited nutritional benefit to the seagrass Halophila ovalis, in culture, following sediment organic matter enrichment.

  Australian Ocean Data Network (AODN)

  Essential nutrients for seagrass growth may be derived from benthic decomposition of organic matter. Two experiments run consecutively from December 2003 to February 2004 tested this idea. Cores of Halophila ovalis (seagrass-vegetated) and unvegetated sediment…

• Importance of Photosynthetic Symbionts in Sponges

  Australian Ocean Data Network (AODN)

  Data was collected on the biogeography and biodiversity of photosynthetic symbionts of marine sponges in Australia. From 2000, sponges from around Australia were sampled using a Diving PAM (pulse-amplitude modulation), molecular analyses and classical taxonomy…
