Sex and the generation gap: seasonal changes in sex allocation. Answering the question 'When is it better to produce more sons than daughters?' has shed important insights into fundamental questions in biology and led to theory that can be applied to problems in agriculture, fisheries and conservation. The project will extend the current theory to increase its applicability, and test it using an introduced pest fish.
Ecology, impact and control of cane toads on the southern invasion front. The invasion of cane toads has killed many native animals in tropical Australia, but the toads’ southern (NSW) invasion front remains unstudied. This project will build on recent research to understand how toads affect southern biodiversity, and will develop new ways to reduce that impact.
Do microbes facilitate the invasion of marine plants? Worldwide, management of invasive species is limited by the understandings of processes that allow invasive species to establish and proliferate in a new environment. It is believed that marine microbes play a critical, but untested, role in the establishment of invasive marine macrophytes. This project aims to test the theory by integrating cutting edge microbial ecology with eukaryote ecology, two largely disparate research areas. Invasive ....Do microbes facilitate the invasion of marine plants? Worldwide, management of invasive species is limited by the understandings of processes that allow invasive species to establish and proliferate in a new environment. It is believed that marine microbes play a critical, but untested, role in the establishment of invasive marine macrophytes. This project aims to test the theory by integrating cutting edge microbial ecology with eukaryote ecology, two largely disparate research areas. Invasive species are a serious threat to biodiversity globally and cost more than $4 billion annually. This project aims to create new knowledge essential for safeguarding Australia’s marine ecosystems from invasive pests, and will place Australia at the forefront of invasion ecology.Read moreRead less
Conservation management of the endangered skink Liopholis slateri. Slater's skink was common in Central Australia 30 years ago, but is now endangered. The project will investigate the lizard response to changing environmental conditions and will develop biological insights that will be important for its conservation.
Population fluctuations: models, mechanisms and management. Changes in plant populations lead to extinctions and invasions in Australia and globally. The project will determine the drivers of plant population change and provide new tools to enable better population management.
Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding ....Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding, prey manipulation and the role of critical senses in the only captive population of sawfishes in Australia. Such knowledge will underpin the development and use of visual, chemical and/or magnetic repellents by fisherman that are still responsible for the loss of large numbers of sawfish as by-catch.Read moreRead less
Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stake ....Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stakeholders. This project will build such an understanding and collaboration, focusing on an endangered snake species. We propose ambitious landscape-scale field experiments that will simultaneously test hypotheses on threatening processes, and restore habitat quality to reverse population declines.Read moreRead less
Metapopulation dynamics of coral communities on the Great Barrier Reef. Mathematical models for the dynamics of coral metapopulations on the Great Barrier Reef will be formulated and parameterised. Analysis of the models will focus on how the effects of competition between corals with different growth forms are influenced by other processes that generate spatial and temporal environmental variation. The project aims to understand how these factors influence the maintenance of high diversity in ....Metapopulation dynamics of coral communities on the Great Barrier Reef. Mathematical models for the dynamics of coral metapopulations on the Great Barrier Reef will be formulated and parameterised. Analysis of the models will focus on how the effects of competition between corals with different growth forms are influenced by other processes that generate spatial and temporal environmental variation. The project aims to understand how these factors influence the maintenance of high diversity in coral communities. It will also provide a modelling framework for predicting how that diversity will be affected by long-term environmental changes, making an important contribution to conservation and management of the Great Barrier Reef.Read moreRead less
Understanding marine biodiversity across vast spatial scales. Large-scale studies of biodiversity are frequently recommended by ecologists, but their costs are prohibitive. More efficient, yet accurate, sampling and analytical procedures are needed. This proposal will provide new quantitative knowledge on patterns of diversity of marine species (fish & invertebrates) from local to regional scales across southern Australia and northern New Zealand. An innovative feature of this research is the c ....Understanding marine biodiversity across vast spatial scales. Large-scale studies of biodiversity are frequently recommended by ecologists, but their costs are prohibitive. More efficient, yet accurate, sampling and analytical procedures are needed. This proposal will provide new quantitative knowledge on patterns of diversity of marine species (fish & invertebrates) from local to regional scales across southern Australia and northern New Zealand. An innovative feature of this research is the contribution of new ecological information with novel analytical procedures to identify the consequences of using more cost-effective techniques on quantifying patterns of biodiversity. This understanding is fundamental to the on-going advancement of ecology and conservation biology.Read moreRead less
Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response ....Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response to climate change. New population modelling methods which integrate plant survival, growth and reproduction along environmental gradients, together with field studies at unprecedented national and international scales, will enable better forecasts of future locations for plant dependent industries and environmental services.Read moreRead less
