Small scale distribution of bioeroding sponges in shallow water at Orpheus Island, Great Barrier Reef

Five permanent 100m transects were established in the southern corner of Little Pioneer Bay, Orpheus Island. The transects, placed perpendicular to the coast, extended from the sandy zone, which is dry at low tide, across the reef flat. A quadrat with 0.5m sides, divided into 25 x 100 cm² quadrats was placed on the substrate along the whole length of each transect. The area of sponge tissue was estimated by counting the 100 cm² quadrats in which sponge tissue occurred. Due to the difficulty in identifying species in the field, seven species or groups of species were distinguished along the transects. These were: encrusting beta-form Cliona orientalis; brown alpha-form sponges (including the alpha-form of Cliona orientalis); brown to orange alpha-form sponges (includes Pione vastifica, Pione caesia and Bernatia vermifera); yellow to orange sponges (includes Cliona celata and Cliothosa hancocki); Aka mucosa; Zyzzya criceta; and others.Substrate characteristics were also recorded along the transects by counting the number of 100 cm² quadrats with over 50% of a given substrate. The substrate categories included: sand; rubble; rock; mud; dead top coral; coral material pavement; soft corals (mainly Sarcophyton); branching corals (Porites cylindrica, Millepora sp. and Porites rus); massive Porites colonies; various live corals; and funnel shaped corals. These characteristics were used to define zones along the transects. The zones were: sand flat; mixed zone (sand, rubble, dead top coral); coral pavement; branching corals; live coral reef relief; and soft coral belts. The amount of exposed calcium carbonate substrate suitable for settlement of bioeroding sponges was recorded.
 This study was initiated to address the lack of ecological data on bioeroding sponges in the Pacific. The objective was to determine small-scale distribution patterns of bioeroding sponges in shallow water across a reef flat and to examine the relationship between distribution patterns and substrate availability, exposure during low tide and water depth.

Factors influencing the acquisition of an attraction response to human provisioning by bottlenose dolphins in Cockburn Sound

The contribution of four factors to the acquisition of attraction responses to human provisioning by dolphins in Cockburn Sound: 
1) individual patterns in the use of high boat density areas; 
2) age-class; 
3) sex; and 
4) close associations with 'experienced' individuals (i.e. individuals that had previously become conditioned to human provisioning) 
were considered using unpublished data from Rebecca Donaldson (1993-1997) and original data collected for the thesis (2000-2003) from Cockburn Sound.  The overall objectives were: 
(a) to identify and characterise predictor variables for the acquisition of an attraction response; 
(b) to examine interactions between these variables; and 
(c) to address the potential influence of social learning.

Coastal Lake Assessment and Management Tool (CLAM): Fiddamans Creek, Coffs Harbour City Council

The Coastal Lake Assessment and Management (CLAM) tool allows stakeholders to assess the social, economic and environmental trade-offs associated with development, remediation and use options for coastal lakes and estuaries. Researchers at the Australian National University (ANU) developed CLAM in 2004 when contracted by the NSW State Government to provide sustainability assessments of 8 coastal lakes. Several projects have since been established directly with local government and NRM groups.
To date, 27 CLAMs have been developed in New South Wales, where they generally fit within estuary management or catchment management plans. To develop these CLAMs and build local capacity to maintain them, ANU-Enterprise Pty Ltd - the commercial company of ANU developed an Accreditation Scheme whereby local consultants are trained in the CLAM approach.

Acrylate in the scleractinian coral, Acropora millepora, from the Great Barrier Reef

Colonies of the scleractinian coral Acropora millepora were collected from Nelly Bay (Magnetic Island), Orpheus Island and Davies Reef in the central Great Barrier Reef in October 2007 at depths of approximately 5 m. Colonies used for acrylate isolation were frozen at -20°C until analysed. The colonies used for acrylate quantification were placed in liquid nitrogen within 10 minutes of collection and later stored at -80°C until analysed. Acrylate was isolated by extracting the frozen coral three times with methanol. The dried methanol extract was partitioned between methanol and hexane. The methanol soluble fraction was separated by reverse phase-C18 silica gel flash column chromatography using increasing proportions of methanol in water, to give nine fractions. The methanol extract and all fractions from the chromatography were analyzed by 1H NMR spectroscopy.The concentration of acrylate was measured from coral nubbins (10 g wet mass), which were extracted three times with methanol and then extracted with dichloromethane (x3) followed by hexane (x5), to extract the remaining lipids, and give a combined dichloromethane/hexane extract. The total organic extract was calculated from the sum of the combined extracts. After extraction, the nubbins were air-dried and weighed to determine the skeleton mass plus nonextractable cellular material. The nubbins were then bleached with 50% bleach, rinsed with MilliQ water three times, air-dried and weighed to determine the skeleton mass. From this, the non-skeletal fresh mass and the non-skeletal dry mass for each sample were determined.Duplicate weighed portions of the methanol extracts were dissolved in 1 ml of the deuterated methanol and 1H NMR spectra were acquired. The amounts of acrylate in the methanol extracts were quantified by measuring the integrals of the three acrylate proton signals and the benzene protons signal and converting to an absolute value by reference to the standard curve. The amount of acrylate was reported as µmol/g non-skeletal fresh mass and µmol/g/ non-skeletal dry mass. The total carbon present in the total organic extract (which also contained NaCl salt) was determined, and the % of carbon present as acrylate carbon in the total organic extract was calculated. Duplicate methanol extracts were dissolved in methanol/water (1:1) and samples containing 2 mg of extract were transferred to tin sample cups and the solvent was allowed to evaporate. The dichloromethane/hexane extracts were dissolved in dichloromethane and duplicate samples prepared in a similar manner. Total carbon analysis was carried out using a LECO TruSpec CN analyser.
 This research was part of a study looking at secondary metabolites from scleractinian corals.
 Acrylate, a C3 compound, is a substantial carbon source in the coral holobiont and is known to be derived from dimethylsulfoniopropionate (DMSP), which has previously been found in corals and other organisms that harbor Symbiodinium spp.

Serpent Project Enfield 6 - measuring megafaunal abundance, diversity and distribution.

SERPENT - Scientific and Environmental remotely operated vehicle (ROV) Partnership using Existing iNdustrial Technology. A highly successful mission resulted after 5 days of ROV operations.  Eight video transects were completed, for megafaunal abundance, diversity and distribution in the area.  Transects were conducted every 450m and extend to 100m from the drill site. Videos will be analysed for megafaunal diversity and habitat mapping during 2006.  
There is only one habitat type at END01 which is soft bottom. There is no evidence of any rock formations or hard bottom of any type.  This will be accounted for when analysing video transects. Preliminary analysis indicates a high density and diversity of megafauna. The main component of the megafaunal community is consistent with soft bottom communities and includes echinoderms (asteroids, echinoids) a host of crustaceans (prawns and large isopods), eels that live in the sediment and some bottom dwelling fish. Unlike at ENC03, there were no large sponge beds only sparsely scattered sponges. 
A variety of prawns, crabs, hagfish, amphipods, isopods and fish were attracted to the bait traps (first experiment). Initial examination of the data suggests that there is a difference in the diversity of organisms that visit the traps (inside vs outside the drill spoil). Isopods and hagfish only appeared to visit traps outside of the drill spoil. Further analysis will validate any trends in the data.
Species collected for determining the level of heat shock protein expression (second experiment):

5 isopods outside of the drill spoil 
5 isopods outside of the drill spoil re-deployed within the drill spoil 
5 isopods outside of the drill spoil re-deployed outside of the drill spoil
5 isopods outside of the drill spoil caged and attached to ROV garage, immersed to seabed and brought to surface again
23 isopods outside of the drill spoil
20 isopods outside of the spoil used for re-deployment experiment 
40 shrimp outside of the drill spoil
57 amphipods outside of the drill spoil
3 hagfish outside of the drill spoil
20 shrimp within the drill spoil
8 amphipods within the drill spoil
1 sea cucumber within the drill spoil

Determining the grainsize of sediment with increasing depth in core GC11, located in the Capricorn Channel

A gravity core (GC11) was collected from a depth of 502 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Samples were separated into different size fractions to determine the % of each grainsize at each sample depth. Although not overly accurate, the information is correlated with analyses of other parameters to impart clues to the environmental changes within the core. The smallest size fraction (&lt;100µm) dominates at all depths, and is particularly pronounced during glacial periods, at 460cm (MIS 10) and at 330cm (MIS 8).

Mangrove forest structure and growth along the arid coast of the Pilbara region, Western Australia

Permanent plots were established in mangrove forests along the arid coast of the Pilbara region to enable long-term measurements of trunk growth, net biomass production and tree survival. Plots were located near Dampier, at Port Headland, in the Bay of Rest (Exmouth Gulf) and in Mangrove Bay (Cape Range National Park) and were chosen to encompass most of the important geomorphological settings in which mangrove forests occur in the Pilbara region. At each location, three to four permanent plots were established in canopy forests of Avicennia marina and Rhizophora stylosa, the dominant mangrove tree species in the region. All trees in each plot were tagged and measured. Where seedlings occurred in the understorey, they were also tagged to follow their growth and survival.
 Permanent study plots were established to:1. carry out long-term observational and experimental studies in the region and2. collect data to compare arid zone mangroves with the more studied, mangrove forests of the north eastern Australian humid tropics.
 This research was a component of the project: "The ecology of arid zone mangroves in northwestern Australia". The project was developed around the working hypothesis that regional mangrove forest structure and growth, mangrove-based food chains and soil biogeochemistry are strongly regulated by aridity. Research was designed to provide scientific information necessary to assess current and potential impacts of human activities on mangroves, including recovery from oil spills, heavy metal stress, changes in soil salinities from salt pond construction and sea level rise.Other components of the project include experiments to measure leaf fall and degradation within these forests and the determination of soil characteristics, including particle size, dissolved and particulate nutrients, salinity and heavy metal content, and microbial parameters such as bacterial sulfite reduction at each site.
