New models for effective surveillance. This project will deliver new methods for generating the information that underpins sound resource management decisions, focusing on statistical techniques to deploy surveillance resources. Results will be relevant to a wide range of applications including setting realistic targets for the effectiveness of biosecurity and quarantine systems.
How does temperature affect complex life histories? A Cost Theory approach. This proposal seeks to understand how temperature affects the relative costs of early life history stages, from
development, through to energy independence for a diverse array of taxa, from seaweeds, to plants to
vertebrates. The proposed research seeks to test the predictions of a new framework, Developmental Cost
Theory, and extend this theory to include germination (for plants) and metamorphosis for animals. The antic ....How does temperature affect complex life histories? A Cost Theory approach. This proposal seeks to understand how temperature affects the relative costs of early life history stages, from
development, through to energy independence for a diverse array of taxa, from seaweeds, to plants to
vertebrates. The proposed research seeks to test the predictions of a new framework, Developmental Cost
Theory, and extend this theory to include germination (for plants) and metamorphosis for animals. The anticipated
goals are to provide clear predictions regarding which species are likely to thrive or suffer under continued global
warming, and a valuable framework for understanding how temperature shapes the life histories of organisms,
including those that are important from an ecological or agricultural perspective.Read moreRead less
The basis of oyster resilience to global environmental change. This project aims to investigate the impact of global environmental change on the survival of Australia’s oyster industry, by combining the science of genetics, physiology and ecology to identify already resilient oysters. Through the first complete understanding of resilience in oysters, including the trade-offs they have made in other fitness traits, the project develops new capacities to 'climate and future-proof' our natural oyst ....The basis of oyster resilience to global environmental change. This project aims to investigate the impact of global environmental change on the survival of Australia’s oyster industry, by combining the science of genetics, physiology and ecology to identify already resilient oysters. Through the first complete understanding of resilience in oysters, including the trade-offs they have made in other fitness traits, the project develops new capacities to 'climate and future-proof' our natural oyster populations and the Australian oyster industry, to enable the restoration of degraded oyster habitats. This project will ensure the future of an iconic and economically important national industry and food source and contribute to preserving the critical cultural links of Indigenous Australians with their lands.Read moreRead less
Quantifying and mitigating the barrier effect of roads on the movement and dispersal of wildlife. In fragmented landscapes, wildlife need to move between habitat patches to exchange genes, increase the size of declining populations and recolonise areas were animals have become extinct. For many species, roads may act as barriers that prevent or limit dispersal, potentially isolating some habitats. In this study, we aim to quantify the extent to which major highways in regional Australia form a ....Quantifying and mitigating the barrier effect of roads on the movement and dispersal of wildlife. In fragmented landscapes, wildlife need to move between habitat patches to exchange genes, increase the size of declining populations and recolonise areas were animals have become extinct. For many species, roads may act as barriers that prevent or limit dispersal, potentially isolating some habitats. In this study, we aim to quantify the extent to which major highways in regional Australia form a barrier to the movement of mammals and invertebrates. We will then test the effectiveness of measures that may facilitate safe crossing by measuring their rate of use, reduction in road kill and increase in population viability. This information can then be used to construct major roads that are more environmentally sustainable.Read moreRead less
Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will ....Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will resolve the roles of environmental drivers of soil respiration across forests; integrate mechanistic understanding of differing plant and microbial responses to temperature within a common modelling framework; and evaluate the implications of this knowledge in predictions of climatic impacts on terrestrial carbon cycling.Read moreRead less
An integrated mechanistic model of species' responses to environmental change: from individual responses to range shifts and beyond. To effectively adapt to future environmental change, reliable forecasts are needed of how human alterations to climate and habitat will affect species. This project integrates cutting-edge methods in nutritional, physiological and spatial ecology to develop new tools for predicting and understanding how species will respond to environmental change.
Has Twentieth Century warming changed southeastern Australia's fire regimes? This project will reconstruct extreme fire seasons and fire events for the past 500 years in three temperate regions of southeastern Australia. This baseline information will extend our historic records of fire, quantify the controls on fire in our landscapes and place recent catastrophic fire events in historical context.
Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling gr ....Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.Read moreRead less
Modelling policy interventions to protect Australia's food security in the face of environmental sustainability challenges . This project will use an innovative scenario modelling approach to quantify the potential impacts of population growth and emerging climate and environmental challenges on Australia’s future food security. In collaboration with an advisory committee it will specify and prioritise policy solutions in terms of their social and economic credentials.
