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…

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…

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…

Changes in growth, internode-distance and nutrient concentrations of the seagrass Halophila ovalis with exposure to sediment sulphide
Australian Ocean Data Network (AODN)Between November 2005 and December the short-term effects of sulphide on the growth, nutrition and morphology of the seagrass Halophila ovalis were investigated in situ in the Swan River Estuary. Sediments within a H. ovalis meadow were enriched with Na2S…
