The Great Barrier Reef long-term chlorophyll monitoring system (RRMMP)

The chlorophyll monitoring under the Reef Plan Marine Monitoring Programme (Reef Plan MMP) is an extension from the Long-term Chlorophyll Monitoring Program, which was initiated by the Great Barrier Reef Marine Park Authority (GBRMPA) in December 1992 as a long-term water quality monitoring program. The chlorophyll monitoring has been managed by the Australian Institute of Marine Science since 1999 and is an important part of the AIMS water quality research and monitoring activities. Since 2005, the Chlorophyll Monitoring is a component of the Reef Plan Marine Monitoring Program, a responsibility of the GBRMPA under the Reef Water Quality Protection Plan.  Sample analysis and data management has been undertaken by AIMS.

The fiddler crab Uca mjoebergi uses colour vision in mate choice

The walking legs, carapaces and chelae of ocypodid crabs, particularly the well-studied fiddler crabs, are often brilliantly coloured. However, despite this array of colours there is still some debate over whether ocypodid crabs are actually capable of colour vision and what role it might play.

The aim of this experiment was to test the colour vision capabilities of fiddler crabs in a biologically significant context. To determine whether Uca mjoebergi use differences in spectral composition to discriminate between colours, and thus possess colour vision, I tested their ability to consistently discriminate yellow from various shades of grey. Experiments were conducted in October 2005 on an intertidal mudflat in the East Point Reserve, Darwin.

When the crabs were reproductively active, during neap tide, wandering females were caught and placed under a container 15 cm from two identical plaster casts of a U. mjoebergi male's 21.8 mm claw. Females were given a choice between a yellow claw (Dulux Tiny Tin yellow enamel) and a claw painted white, 75% grey, 50% grey, 25% grey or black (made by mixing appropriate amounts of white and black Dulux Tiny Tin enamel paint). It was recorded which claw the female approached within 2 cm. Each combination was tested until 15 females successfully made a choice. 

The same experiment was conducted with two tethered, size matched (within 1 mm claw length), and handedness-matched males in place of the plaster claws. The males were tethered with 1 cm of cotton super-glued to their carapace and tied to a nail stuck in the ground, allowing some restricted movement. I painted the males' claw either with the same yellow paint as above or with the light yellow paint, made by mixing one part yellow to 14 parts white paint. The experiment was repeated 25 times using different pairs of males and new females each time.

The feeding ecology of the intertidal limpet, Siphonaria diemenensis at Griffith Point, Victoria.

This study was conducted from December 1979 to December 1981 to determine the diet of Siphonaria diemenensis in the high and low intertidal zone on the rocky shore at Griffith Point, San Remo, Victoria. 

Gut contents analysis indicated that in both zones the limpets were feeding primarily on encrusting brown algae (e.g. Ralfsia verrucosa and Scytosiphon lomentaria). In an experimental manipulation, limpets were excluded from 15 x 15cm areas of rock to determine the change in algae cover in the presence and absence of limpets. Two runs of this experiment were conducted in Zone 1 from February to September and from September to December in 1980. The change in algae cover during the experiment was generally greater in the exclusion plots. This supports conclusions from the gut contents analysis, that encrusting brown algae form the major part of the diet of S.diemenensis.

A growth experiment was conducted from 5 September to 15 November 1981 in Zone 1. There were 12 enclosures (15 x 15cm) with 15 limpets in each. Three enclosures were assigned to each of the 4 treatments; Ralfsia, Scytosiphon, scraped or bare. At the end of the experiment, 5 individuals were collected from each enclosure and their shell lengths and dry tissue weights measured. The mean shell length and dry tissue weights were greater in the Ralfsia and Scytosiphon treatments compared to the bare and scraped indicating that the presence of brown algae can be beneficial to this species of limpet. 

Algal abundances were monitored throughout this study by analysing photographs of permanently marked quadrats (50 x 50cm) at each of the study sites (3 sites in Zone 1 and 2 sites in Zone 2). Photographs were taken at monthly intervals from December 1979 to December 1981. In Zone 1, there was a clear seasonal trend in algae cover with a minimum cover in summer (January to March) and a maximum in spring (August to December). In Zone 2, there was no seasonal trend but a 100% cover of encrusting brown algae at all times. 

Individual adults were marked in both zones in April 1980 (42 in Zone 1 and 43 in Zone 2) and again in January 1981 (104 in Zone 1 and 66 in Zone 2) by cementing a small numbered label to the shell with a clear epoxy resin. The positions of marked individuals were measured regularly over a period of 8 weeks in 1980 and 1981. Over 70% of individuals were observed to home back to their original positions after 8 weeks with the remainder moving to new positions. Limpets were observed to begin to move at least 1 hour before being exposed to air on a receding tide, and to cease movement between 1 and 2 hours after they were uncovered.

The epibenthic fauna of seagrass beds and bare sand in Princess Royal Harbour and King George Sound, Albany, south-western Australia

A short-term sampling programme in Princess Royal Harbour aimed to compare the mobile macrofauna of a shallow eutrophic seagrass habitat (Posidonia australis) with an adjacent sand habitat.  In addition, the mobile macrofauna of an apparently oligotrophic seagrass habitat (Posidonia sinuosa) in King George Sound with an adjacent sand habitat.  Species diversity and abundance of fish, macro-crustaceans and molluscs among habitats were also investigated.  This sampling was carried out on series of nights between 15th and 25th January 1988.

The effects of copper antifouling paints and marinas on the ecology of marine sessile epifaunal assemblages

This thesis has used a field based approach to assess the effects of copper liberated from antifouling paints on sessile epifaunal (or fouling) assemblages in southeastern Australia. In the field the effects of dosed copper may be influenced by site conditions, or because the organism has developed tolerance to exposure.   To explore these possible effects experiments were conducted inside and outside of two enclosed marinas.  Marinas were located at St Kilda (Port Phillip Bay) and Hastings (Western Port Bay), Victoria. At St Kilda,  sites were located inside the St Kilda Marina and at St Kilda Pier.  At Hastings, sites were located inside Westernport Marina and at Hastings Jetty.  Additional sites were also sampled occasionally over the study period. Studies were carried out between  1997-1999.  A novel copper dosing system was developed for use in the field. 

Studies comparing epifaunal assemblages inside and outside the two marinas found that marinas produced different assemblages.  The marinas exerted common effects on some functional groups, but effects at the species level differed at each marina.
 
The effects of dosed copper inside and outside the two marinas were tested on:  i) the early recruitment of assemblages, and ii) the growth rate and competitive ability of colonial fouling organisms.  Results were characterised by high spatial and temporal variability.  Copper dose affected a number of species recruiting to the plates but was rarely found to significantly alter growth rates of the colonial organisms; this may be attributed to the high variability observed in growth rates.  The competitive ability of colonies was not found to be affected by copper dose or marinas, but few experiments examined this aspect.  

Reciprocal transplants of settlement plates between sites and copper doses showed that the effect of marinas on assemblages was more important than dosed copper, even though dose levels were well above background concentrations. This is probably due to a large number of factors associated with marinas over and above the effects of increased background heavy metal pollution.  Several taxa appeared to adapt to local conditions or copper dose and some appeared to show heterogeneity in response to copper dosing or an ability to acclimate to dose.  These types of findings have important implications for the manner in which we apply the findings of traditional laboratory-based ecotoxicology experiments to environmental management.

The effects of buy-back programs in the British Columbia Salmon Fishery: WORKING PAPER

This record describes, and links to a working paper published through the Economics and Environment Network at The Australian National University in Canberra. The paper was prepared for the International Workshop on Fishing Vessel and License Buy-Back Programs, held at the University of California between March 22nd-24th, 2004. 
*****
Policy makers have implemented five distinct buybacks of either vessels or salmon licenses over the past three decades in the British Columbia (BC) salmon fishery. The earliest buyback was one of the first of its kind in any fishery and the most recent buyback is one of the largest ever in terms of reducing vessel numbers and the funds used. This paper reviews the circumstances under which these buybacks were conducted with an emphasis on their impact on reducing fishing capacity and effort. The focus is on the two most recent buybacks that took place in 1996 and 1998-2000, what has been learned and what they have achieved.

The percentage of CaCO3 in samples taken from various depths in core GC12, located in the Capricorn Channel

A gravity core (GC12) was collected from a depth of 990.5 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The percentage of CaCO3 in samples collected from different depths were analysed, along with other parameters, to determine changes in carbonate mineralogy and terrestrial influx. Levels of CaCO3% exhibit an higher percentage of >60% during the middle of Marine Isotope Stage (MIS) 3, levels similar to those seen in MIS 1. Throughout MIS 2 and during the glacial termination the CaCO3% remains relatively constant at ~60%. CaCO3 drops to 50% prior to a possible Antarctic cold reversal (between 14 ka BP and 12 ka BP) at 80cm in the core, before recovering to the 65-70% in the Holocene again.

The effect of damage on the growth, reproduction and storage of lipids in the scleractinian coral Pocillopora damicornis (Linnaeus)

A population of the scleractinian coral Pocillopora damicornis (Linnaeus) was examined at Rottnest Island, off the Western Australian coast. This is a temperate zone and an area under considerable tourist pressure. Experiments were conducted at Little Salmon Bay and Mary Cove to investigate the effect of mechanical damage on the growth, reproduction and storage of lipid to see whether patterns of energy allocation were affected. These parameters were measured simultaneously 14 times over 13 months from July 1988 to September 1989.

The economic payoffs from marine reserves: resource rents in a stochastic environment: WORKING PAPER

This record describes, and links to a working paper produced through the Crawford School of Economics and Government at The Australian National University in Canberra.
*****
The paper analyses the economic payoffs from marine reserves using a stochastic optimal control model. The results show that even if the reserve and harvested populations face the same negative shocks, harvesting is optimal, the population is persistent and with no uncertainty over current stock size, a reserve can increase resource rents. Using actual fishery data we demonstrate that the payoffs from a reserve, and also optimum reserve size, increase the larger is the magnitude of the negative shock, the greater its frequency, and the larger its relative impact on the harvested population.

The ecology of the two populations of the intertidal pulmonate limpet, Siphonaria diemenensis.

The ecology of 2 populations of the limpet Siphonaria diemenensis were investigated on the rocky intertidal shore at Griffith Point, San Remo, Victoria from 1979 to 1981. One population was on flat rock in the high intertidal area (Zone 1) and the other population was on the boulders in the low intertidal area (Zone 2). In Zone 1, there were 3 sites (combined area of 3.146 m2) and 12 permanently marked 0.25m2 quadrats and in Zone 2, there were 2 sites (combined area of 1.291m2). 

The population dynamics of the limpets were investigated by measuring shell lengths and dry weights of individuals in the 2 zones. Fences were used to enclose limpets or exclude limpets from areas of the substratum. Details of each experiment are described in the related records.

The ecology and trophic role of caridean shrimps in the eelgrass community of Western Port, Victoria

This study investigated the ecology of caridean shrimp in eelgrass habitats in Western Port Bay, Victoria from July 1977 to January 1980. The study sites were located on the Churchill Tidal Flats on the northern side of Phillip Island, which are dominated by the eelgrass species, Heterozostera tasmanica and the cardiean shrimp species, Macrobrachium intermedium, Pontophilus candidus, Hippolyte caradina and Chlorotocella leptorhyncus. Benthic trawls were used to sample the shrimp populations at an offshore (Site A) and inshore (Site B) eelgrass site. Another site on a mudflat (Site C) was sampled to determine the movement patterns of shrimps between the mudflats and adjacent subtidal eelgrass areas. Sampling was undertaken every 1 to 2 months at night time during high tide. Plankton tows were used to monitor the presence of larval stages of shrimp in the water column. Details of each experiment and results are described in the related records.

The ecology and impacts of the introduced basket clam, Corbula gibba in Port Phillip Bay, Australia

This thesis describes the ecology and impact of the introduced European basket clam, Corbula gibba (Olivi, 1792), in Port Phillip Bay, Victoria. A bay-wide survey conducted in 1998 found C. gibba throughout the bay but it was significantly more abundant in deeper, muddier sites. Life history studies carried out at three sites found that two sites were dominated by a single cohort of large adults while the third site had one cohort of adults and one of juveniles.  This juvenile cohort grew at a rate of about 4 mm2 per month but experienced high mortality, with only 0.5% surviving a six month period. Longer term abundance patterns available at St. Leonards, and supplemented by this study, found that, between 1969 and 1999, adult density varied between 0 and 106 individuals per m2 while juveniles were found in varying densities in 5 of 6 years sampled. The effect of anthropogenic disturbance on resident populations and subsequent invasion by C. gibba into disturbed sites was assessed experimentally using scallop dredging. Scallop dredging did not affect resident populations but the impact on subsequent invasion by C. gibba could not be determined as recruitment failed to occur over the study period and adult migration was not observed. The effect of ambient densities of C. gibba on endemic species such as the commercial scallop, Pecten fumatus, was investigated experimentally in the field.  These experiments found that C. gibba significantly reduced the size and growth of juvenile P. fumatus to a greater extent than an equivalent number of conspecific scallops. Competition for shared food resources did not appear to be the mechanism underlying this impact, however, as dietary studies found that C. gibba was not a superior competitor. Additional studies found that C. gibba did not affect the recruitment of the native bivalves, Mytilus edulis and Electroma Georgiana, but significantly reduced conspecific recruitment. This effect is likely to have implications for the structure of C.gibba populations in the bay.
