The role of copper in facilitating the invasion of sessile marine invertebrate communities by pests: effects of copper pulse frequency in developing assemblages

Disturbance events are thought to provide an opportunity for the colonisation and establishment of invasive species.  Contamination of coastal waters with copper from sewage outfall and antifouling paints may create a disturbance that favours the establishment of introduced sessile invertebrates.  This study examines if the frequency of experimentally applied doses of copper sulfate increases the abundance of introduced sessile invertebrate species within developing (2-weeks old) and established (9-months old) assemblages.  Responses to regular and irregularly applied doses of copper were also tested in developing assemblages.

This dataset gives the effects of copper pulse frequency on the number of native and introduced taxa within developing (2-weeks old) sessile invertebrate assemblages.  Studies were carried out over 16 weeks between October 2004 and January 2005 at two sites in Port Phillip Bay, Victoria; Workshops Jetty, Williamstown and Point Henry Pier.  Workshops Jetty is reported to have higher abundances of sessile invertebrates and is more polluted than Point Henry Pier, providing a comparison between sites with different community assemblages and environment conditions.  At Workshops Jetty, four treatments were tested: an undosed control, or copper pulses applied every 4, 3 or 2 weeks.  At Point Henry, the same treatments were applied, except for the copper pulse application every 3 weeks. Overall, this study found no evidence to support the hypothesis that disturbance facilitates invasions by introduced species. Disturbance had no effect on the proportion of introduced species and there were no clear differences in the responses on introduced and native species. Whether a species benefited from a disturbance appeared to depend more on its life history characteristics, rather than its point of origin.

The relative abundance (%) of planktonic foraminifera over time in core MD032607, located off the coast South Australia

The advent of deep-sea drilling in the 1950's prompted the use of planktonic foraminifera (unicellular protozans) as palaeoceanographic indicators. They provide a natural archive of past environmental changes due to their global distribution, their prolific productivity and sensitivity to environmental variations.The highest species abundance of foraminifera in core MD032607 was recorded by Globigerina bulloides (~45%) during the penultimate glacial period (MIS 6) and, generally, was the most abundant with an average abundance of 19.5%. The dominance of the sub-polar, transitional species, Ga. bulloides in this core suggests the influence of cold, nutrient-rich water during certain isotopic stages. Conversely, the dominant warm and oligotrophic species Globigerinoides ruber recorded its lowest abundance in Marine Isotope Stage (MIS) 6, and is totally removed from the record (0%) at 146K, 142K, and 139K yrs BP.

The relative abundance (%) of planktonic foraminifera over time in core MD 002361, located on the shelf edge, offshore Western Australia

The advent of deep-sea drilling in the 1950's prompted the use of planktonic foraminifera (unicellular protozans) as palaeoceanographic indicators. They provide a natural archive of past environmental changes due to their global distribution, their prolific productivity and sensitivity to environmental variations. The most abundant species within core MD002361 is the subtropical species Gs. ruber. High abundances =30% are seen during the interglacial periods Marine Isotope Stages (MIS) 11, 9, 7, 5 with peak abundance (37.7%) during the Holocene. Other tropical and subtropical species follow this pattern. The transitional, deep dwelling species Gr. inflata has the most distinct abundance change within core MD002361. This species is absent during the interglacial periods but achieves high relative abundances (~20-30%) during glacial periods.

The relative abundance (%) of planktonic foraminifera over time in core BAR 9403, located off the coast of Sumatra

The advent of deep-sea drilling in the 1950's prompted the use of planktonic foraminifera (unicellular protozans) as palaeoceanographic indicators. They provide a natural archive of past environmental changes due to their global distribution, their prolific productivity and sensitivity to environmental variations. 

The most obvious change in relative abundance in core BAR9403 (off the coast of Sumatra) is shown by sub-polar to transitional 'upwelling' species Ga. bulloides with abundances of 26% at approximately 14,000yrs BP and 22.7% during the Holocene. This is compared to the periods from Marine Isotope Stage (MIS) 3 to the Last Glacial Maximum (LGM) where the relative abundance of Ga. bulloides is generally <10%. Gr. menardii, a tropical 'upwelling' species, also increases its relative abundance during MIS 2 from <8% during MIS 3 to a peak abundance of 16% at ~17,000yrs BP.

The population dynamics of the gastropod Lepsiella vinosa on the West Head rocky shore in Victoria

This study surveyed the size distribution of Lepsiella vinosa at 3 sites on the rocky shore at West Head, Victoria. Monthly or bi-monthly searchers were conducted from June 1975 to August 1978 during spring low tide. Every individual L.vinosa found at the 3 sites was measured to the nearest 0.01cm with vernier calipers. To determine recruitment of L.vinosa to the shore, individuals were arbitrarily designated as juveniles (< 0.8 cm) or adult (> 0.8 cm). The type of microhabitat where each individual was found was recorded at Sites 1 and 2 for the searchers conducted in spring (November 1977), summer (January 1978), autumn (April 1978), and winter (August 1978). 

There were larger individuals of L.vinosa at higher intertidal levels (Site 1) compared to the mid- and lower sites (Sites 2 and 3). The recruitment of juveniles could not be determined from the size frequency distribution at any of the sites. There was more L.vinosa than expected in the rock pool habitats compared to the bare rock in all seasons except for winter at Site 2. There was high variability in abundance in the Lichinia habitat between all seasons and sites.

The percentage of calcium carbonate in samples taken from various depths 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). The percentage of calcium carbonate in samples collected from different depths were analysed, along with other parameters, to determine changes in carbonate mineralogy and terrestrial influx. The results indicate that CaCO3% increases rapidly at the terminations, with highs during the interglacials and as low as 50% during some of the glacials. The CaCO3% highs of around 85% coincide with very low sedimentation rates of <1 cm/kyr and are probably dominated by pelagic productivity.

The percentage of calcium carbonate in samples taken from various depths in core GC10, located in the Capricorn Channel

A gravity core (GC10) was collected from a depth of 335 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The percentage of calcium carbonate in samples collected from different depths were analysed, along with other parameters, to determine changes in carbonate mineralogy and terrestrial influx. The results indicate that the minimums in CaCO3% precede the glacial maximums (at 130cm), then rapidly increase during deglaciations to reach a peak in CaCO3% of ~75% during the mid-interglacial.

The percentage of calcium carbonate in samples taken from various depths in core GC09, located in the Capricorn Channel.

A gravity core (GC09) was collected from a depth of 166m within the Capricorn Channel, southern Great Barrier Reef (GBR). The percentage of calcium carbonate in samples collected from different depths was analysed, along with other parameters, to determine changes in carbonate mineralogy and terrestrial influx. The lowest percentage of calcium carbonate was recorded at ~60cm depth corresponding to the Last Glacial Maximum (LGM). The increase in the percentage of silt and mud during the LGM relates to a reduction in bioclastic carbonate production.

The percentage breakdown of carbonate/non-carbonate fractions in core GC04, located off the coast of New Caledonia

Core GC04, was collected from the southeastern side of the New Caledonian Basin (22.99965 S, 166.150716 E). Carbonate percent in the curve has an average value of ~79% and varies between 51.4% and 88.8%. Carbonate pecent does show small variations in scale and repeating patterns, however data tends to stay between 70-80%. It is interesting to note that the carbonate percent minimum of 51.4% occurs at the beginning of isotope stage 4 (~73Ka BP). This anomaly is relatively simultaneous to a decrease in 18O and slight increase in sedimentation rate. Significant non-carbonate sediments include glass shards, sub-rounded quartz, radiolarians, sponge spicules, manganese nodules and 'red opaque' material. Trends of glass shard and quartz percentages can be seen in the results. Radiolaria and sponge spicles tend not to show any definite trend, however both tend to increase subsequent to a broader non-carbonate sedimentation increase.

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

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 multivariate regression model.

Species richness and total biomass is compared between cleared sites and control sites.   Also the ability of pre-existing juvenile sporophytes to survive change in conditions associated with removal of their canopy was measured and as well as the relationship between Ecklonia radiata canopy and its associated understorey on reefs on reefs with simple and complex topography.

The Indian Ocean Tsunami: Economic Impact, Disaster Management and Lessons: WORKING PAPER

This record describes, and links to a working paper produced through the Division of Economics, Research School of Pacific and Asian Studies, (RSPAS) based at The Australian National University in Canberra. ***** The purpose of this paper is to document and analyse the immediate economic impact of the Indian Ocean tsunami generated by the Sumatra-Andaman earthquake of 26 December 2004 and the disaster management process in the immediate aftermath of the disaster with a focus on the two worst affected countries - Indonesia (Aceh province) and Sri Lanka. The 26 December Tsunami is unique among large disasters in recorded human history, not only because of the sheer number of casualties and massive displacement of people, but also because of the unprecedented international donor response and the logistic challenges faced by international organizations and aid agencies in organising and coordinating relief efforts. Our preliminary findings point to the importance of educating the public about simple precautions in the event of a disaster and enforcement of coastal environmental regulations as disaster prevention policies. The findings also makes a strong case for designing policies and programs, as an integral part of national development strategy, for mitigating the impact of natural disasters on the poor and highlights the need for combining international aid commitments with innovative approaches to redressing problems of limited aid absorptive capacity in disaster affected countries.

The importance of predation in shaping marine sessile communities at Williamstown, Victoria

Predation on newly settled individuals has been shown to shape sessile invertebrate communities of the northeast coast of North America.  This study tests if this response can also be observed at other geographic locations that support different assemblage of sessile invertebrates.  The effects of predation in early post-settlement assemblages were tested at two locations in Victoria; Workshops Pier, Williamstown and Queenscliff Pier, Queenscliff during the summer of 2005-2006.  At each site, early post-settlement assemblages of sessile invertebrates were established and subsequently exposed to a series of predation exclusion treatments of varying durations.  This dataset gives the abundances of sessile invertebrates on plates at Williamstown Pier after the initial 4 day settlement period, and after subsequent exposure to 3, 15 and 35 days exposure to three predation exclusion treatments. The predation treatments were i) uncaged, no predator exclusion, ii) full 2 mm mesh cage, total predator exclusion and iii) full 10 mm mesh cage, exclusion of large predators only.  In addition two cage control treatments were established to identify if the cages themselves caused a change in the sessile invertebrate assemblages.  Cage controls were partial cages constructed from both 2 mm and 10 mm mesh. The results indicated that, although predators were common, predation did not exert a strong influence on sessile invertebrate communities at Williamstown.
