Optimizing the allocation of resources for defending marine protected areas against invasive species. The National Representative System of Marine Protected Areas contributes directly to the protection of marine biodiversity, and to Australia's international obligations under the UN Convention on Biological Diversity. Non-indigenous species have potential to undermine native biodiversity in marine protected areas across Australia.

The National Representative System of Marine Protected Areas contributes directly to the protection of marine biodiversity, and to Australia's international obligations under the UN Convention on Biological Diversity. Non-indigenous species have potential to undermine native biodiversity in marine protected areas across Australia. By identifying the most effective strategies for dealing with potential incursions of non-indigenous species in Victorian marine national parks and sanctuaries, the project will make a valuable contribution to the viability of local marine ecosystems and the maintenance of biodiversity. Furthermore, it will provide a template to aid similar decision-making in other marine protected areas around the country.Read moreRead less

Stress, virulence and bacterial disease in temperate seaweeds: the rise of the microbes. Climate change is predicted to increase the spread and virulence of pathogens, and decrease the resistance to disease via temperature stress on the hosts. Combined with other human impacts (higher nutrients, pollution), we may be facing a major rise in the effect of disease on natural communities. However, these effects are largely unstudied. We will investigate the impact of marine pathogens on kelps and ....Stress, virulence and bacterial disease in temperate seaweeds: the rise of the microbes. Climate change is predicted to increase the spread and virulence of pathogens, and decrease the resistance to disease via temperature stress on the hosts. Combined with other human impacts (higher nutrients, pollution), we may be facing a major rise in the effect of disease on natural communities. However, these effects are largely unstudied. We will investigate the impact of marine pathogens on kelps and other seaweeds when they are stressed by temperature, elevated nutrients or other anthropogenic stressors. Kelp are the 'trees of the oceans', the organisms responsible for creating much of the habitat that fishes and other organisms live in. The loss of kelp forests due to disease would radically change these environments.Read moreRead less
Do costs of dispersal reduce connectivity in marine invertebrate populations? Current approaches to marine management - designing marine reserves, understanding pest incursions, and managing fisheries, acknowledge that marine animals exist in isolated local populations, connected by dispersal. Dispersal is crucial for local populations to persist or be managed sustainably, but our understanding remains poor and often limits our management. Most current approaches to estimating connectivity are ....Do costs of dispersal reduce connectivity in marine invertebrate populations? Current approaches to marine management - designing marine reserves, understanding pest incursions, and managing fisheries, acknowledge that marine animals exist in isolated local populations, connected by dispersal. Dispersal is crucial for local populations to persist or be managed sustainably, but our understanding remains poor and often limits our management. Most current approaches to estimating connectivity are adequate only if all dispersers are equally successful at establishing. Dispersal, however, is risky or costly, and we propose that these costs reduce the success of colonists from more distant populations. If this is correct, persistence of local populations may rely disproportionately on other nearby local populations.Read moreRead less
Post-settlement mortality as a filter for variable settlement in marine invertebrates. Most marine organisms have a planktonic dispersive stage. Recruitment from this stage into adult populations is a key process. Variations in recruitment affect our ability to manage fisheries, plan national parks, and predict environmental impacts. Our ability to understand variation in recruitment is limited by our poor understanding of one key component of recruitment, post-settlement mortality. I will t ....Post-settlement mortality as a filter for variable settlement in marine invertebrates. Most marine organisms have a planktonic dispersive stage. Recruitment from this stage into adult populations is a key process. Variations in recruitment affect our ability to manage fisheries, plan national parks, and predict environmental impacts. Our ability to understand variation in recruitment is limited by our poor understanding of one key component of recruitment, post-settlement mortality. I will take several common, economically important, marine invertebrates, and determine how strongly post-settlement mortality affects overall recruitment. By looking at several species, I will be able to identify general patterns applicable to a wider range of species.Read moreRead less
Hazard identification, risk assessment and decision analysis for conservation and management of Australian marine parks. Victoria is the first jurisdiction in the world to proclaim an entire system of marine protected areas at once.

Victoria is the first jurisdiction in the world to proclaim an entire system of marine protected areas at once. The new management responsibilities have created imperatives for robust, scientifically defendable approaches to identifying threats, setting management priorities and developing monitoring systems. This project will develop, for the first time, a risk assessment protocol that has due regard for the perception of risks by individuals, and ensures that stakeholder values are an intrinsic part of decision-making. The protocol will create a system that stays faithful to the priorities of those who bear the risks, while using technical methods to ensure that models are consistent and that monitoring provides pertinent information.Read moreRead less
Building effects of marine pests into nutrient management strategies. The input of nutrients has long been a key management focus for coastal waters, and the organisms living in soft sediments play a very important role in the removal of nutrients from these waters, thereby reducing the risk of environmental degradation. In recent years, marine pests have emerged as a major threat, with the potential to alter the abundances of a wide range of native organisms. Nutrients and pests have largely ....Building effects of marine pests into nutrient management strategies. The input of nutrients has long been a key management focus for coastal waters, and the organisms living in soft sediments play a very important role in the removal of nutrients from these waters, thereby reducing the risk of environmental degradation. In recent years, marine pests have emerged as a major threat, with the potential to alter the abundances of a wide range of native organisms. Nutrients and pests have largely been treated as independent threats, but pests could interfere with denitrification processes. We will test whether this occurs, and provide key information for managers devising nutrient management strategies.Read moreRead less
Management of coastal lakes to minimise invasion. The European shore crab has the potential to undermine the productivity of Australia's estuaries and devastate our shellfish industries, worth over $50 million p.a. This project will provide estuarine managers with the data urgently needed to prevent spread of this pest species. In doing so, it will help to ensure the future prosperity of our seafood industries and the sustainability of our unique coastal biodiversity.

This project will provide estuarine managers with the data urgently needed to prevent spread of this pest species. In doing so, it will help to ensure the future prosperity of our seafood industries and the sustainability of our unique coastal biodiversity. The outcomes of this project will be applicable to the management of many of the > 200 introduced marine species already present within our coastal waters. Importantly, the project will also contribute to research training in new techniques to protect Australia from future pest invasions.Read moreRead less
Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimi ....Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimilate these metals is critical to the generation and aggressiveness of the toxins produced. These processes will be investigated in this study and conceptual and mathematical models will be developed which will assist in assessing management options for estuarine and coastal environments.Read moreRead less

How do animals find food, choose places to live and select mates? How do insect swarms and fish schools make collective decisions without leaders? These are fundamental questions in understanding the ecological roles and environmental impacts of endangered native and damaging invasive animals. The video analysis suite will be used to analyse the behaviour of such animals in environments from the land to the deep-sea floor; track exceptionally fast movements during courtship and predator escape; study how animals achieve temperature balance in complex habitats; understand the dietary choices of herbivores, and discover the rules that govern the behaviour of swarms.
