Population Structure in the Australian Sea Lion based on Microsatellite Markers
Australian Ocean Data Network (AODN)Tissue samples were collected from newly born pups from 15 individual colonies between 1989 and 2000, to look at variable nuclear microsatellite markers to allow the investigation of genetic population structure and sex-biased dispersal.

Population Subdivision in the Australian Sea Lion based in mtDNA Variation
Australian Ocean Data Network (AODN)Tissue samples were collected from newly born pups from 15 individual colonies between 1989 and 2000, to determine the genetic structure of populations of N. cinerea, with a view to understand the degree of connectedness of different colonies, the role of…

Substantial asexual recruitment of mushroom corals contributes little to population genetics of adults in conditions of chronic sedimentation.
Australian Ocean Data Network (AODN)The contribution of asexual versus sexual recruitment to populations of the mushroom coral Fungia fungites was investigated at 2 sites with contrasting sediment regimes, located 5 km apart in the Dampier Archipelago, Western Australia. One site was exposed to…

Abundance and Breeding Cycle of the Australian Sea Lion in Western Australia
Australian Ocean Data Network (AODN)This study assessed sea lion pup production at 9 breeding sites in Western Australia (ranging from Houtman Abrolhos Islands to Six Mile Island at the start of Great Australian Bight) from 1988 to 2001 to estimate population size overall. Trends in pup…

Size-structures of populations of the mushroom coral Fungia fungites: the role of disturbance.
Australian Ocean Data Network (AODN)Changes in the size-structure of populations of the mushroom coral Fungia fungites were quantified at two reefs in the Dampier Archipelago during four annual surveys from April 1998 to April 2001. Exposure to disturbance was predicted to affect the size and…

A Demographic Analysis of Populations of a Mushroom Coral Exposed to Contrasting Levels of Disturbance
Australian Ocean Data Network (AODN)The rates of sexual and asexual recruitment were quantified over 3.5 years, in addition to the rates of growth, injury and survival of the different sizes and stages of polyps of Fungia fungites at Mainland and East Lewis reef in the Dampier Archipelago (see…

Long term studies of population and community structure on intertidal rock platform at Rottnest Island
Australian Ocean Data Network (AODN)Data has been collected on the patterns of distribution and abundance, recruitment, survival and growth of macroinvertebrate fauna on the rocky intertidal shores at Rottnest Island over last 30 years.

The biology and fishery of Roe's abalone (Haliotis roei) Gray in south-western Australia - Series Summary
Australian Ocean Data Network (AODN)Four critical aspects of Roe's abalone (Haliotis roei) Gray biology and population dynamics were investigated: (1) the stock structure; (2) the recreational catch; (3) an appropriate growth curve and description of size at age; and (4) abundance measures…

Reproduction of Holothuria whitmaei (sea cucumber) in the Indian and Pacific Ocean regions of Australia
Australian Ocean Data Network (AODN)Seasonal trends in the gonad index (GI) of two widely separated populations of black teatfish, Holothuria whitmaei (Bell, 1887), were investigated between Pacific (Great Barrier Reef) and Indian Ocean (Ningaloo Reef) coral reefs of Australia.

Bioturbation and seasonal activity of Holothuria whitmaei (sea cucumber) at Ningaloo Reef, Western Australia
Australian Ocean Data Network (AODN)Data on the rates of activity and sediment egestion of Holothuria whitmaei (Bell 1887) at Ningaloo Reef were collected over a two year period between 2002 and 2003.

Aggregations of common holothurians on reef flats of Coral Bay, Ningaloo Reef, North Western Australia
Australian Ocean Data Network (AODN)The distribution of three sea cucumbers (H. whitmaei (Bell 1887), H. atra (Jaeger 1933) and S. chloronotus (Brandt 1835) in the vincinity of Coral Bay, Ningaloo Reef, Western Australia was measured. There was an emphasis on factors that may contribute to the…

Genetic subdivision of Roe's abalone, Haliotis roei Grey in south-western Australia
Australian Ocean Data Network (AODN)Starch-gel electrophoresis was used to investigate population structure of the commercially and recreationally exploited abalone, Haliotis roei. Samples were obtained from abalone taken from 10 sites in south-western Australia between March 1997 and April…

Effect of invasive tagging on the activity behaviour of Holothuria whitmaei (sea cucumber) at Ningaloo Reef, Western Australia
Australian Ocean Data Network (AODN)Data were collected to evaluate the practicality of marking the dorsal tegument as a tagging method for short-term mark-recapture studies of holothurians (Holothuria whitmaei, Bell 1887) and to compare the behaviour of 'marked' to 'unmarked' control animals.

Ecosystem engineering actions of Wedge-tailed Shearwaters, Puffinus pacificus on Rottnest Island, Western Australia
Australian Ocean Data Network (AODN)The Wedge-tailed Shearwater (Puffinus pacificus) is an ecosystem engineer: it physically modifies habitat, by burrow nesting, in a manner that modulates resource flows and other species within nesting colony ecosystems. My work explores the ecosystem…

Spatial distribution and temporal shifts in the biology of Holothuria whitmaei (sea cucumber) at Ningaloo Reef, Western Australia - Series Summary
Australian Ocean Data Network (AODN)Data were collected to: - i) investigate the spatial distribution and temporal changes in the biology of H.whitmaei (Bell, 1887)(from the perspective of activity, feeding and reproduction), and, - ii) provide an overall synthesis of the results, whilst placing…

Diurnal rhythms of activity, sediment egestion and cryptic behaviour of Holothuria whitmaei (sea cucumber) at Ningaloo Reef, Western Australia
Australian Ocean Data Network (AODN)The diurnal rates of activity and sediment egestion on three seperate occasions in January, April and August, 2003, and the cryptic behaviour on one occasion in August, 2003 were measured to determine diurnal patterns of holothurian behaviour.

Acute Sedimentation Causes Size-Specific Mortality and Asexual Budding in the Mushroom Coral Fungia fungites
Australian Ocean Data Network (AODN)Field experiments investigated the effect of acute sedimentation on polyp injury, mortality and bud production, in the mushroom coral Fungia fungites in the Dampier Archipelago. Small (3-5 cm), medium (8-12 cm), and large (15-20 cm) polyps were covered with a…
