Global climate change and the impacts of temperature extremes on terrestrial biodiversity. Increasing severity of climate extremes is a disturbing implication of global climate change; yet little is known about the effects of such extremes on the natural world. This project aims to understand the vulnerability of biodiversity to current and future extremes, and to inform conservation efforts and minimise future impacts.
Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Aus ....Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less
Consequences of temporal community turnover. This project aims to understand how environmental change affects compensatory dynamics of species. Species numbers do not change over time in local ecological communities, but species composition is changing at an unprecedented level across the globe. The implications of these compensatory dynamics for the resilience of ecological communities and how they affect ecosystems are important for community ecology and conservation. This project could reveal ....Consequences of temporal community turnover. This project aims to understand how environmental change affects compensatory dynamics of species. Species numbers do not change over time in local ecological communities, but species composition is changing at an unprecedented level across the globe. The implications of these compensatory dynamics for the resilience of ecological communities and how they affect ecosystems are important for community ecology and conservation. This project could reveal the functional consequences of temporal community change, contributing new insights into the effects of environmental change especially on soil ecosystems.Read moreRead less

Summary
How will Australian rainforest species cope with climate warming? This project plans to investigate how, and how much, rainforest tree species will adjust to warmer temperatures. Understanding the temperature dependence of physiological processes of Australian rainforest trees and how they are related to climate variation is critical. This should enable prediction of how species will adjust to warmer temperatures, what their thermal tolerances are and how future species distribution ranges may c ....How will Australian rainforest species cope with climate warming?

Do marine reserve networks work? Larval connectivity, sustainable harvesting and ecological resilience. The Great Barrier Reef is a globally iconic marine ecosystem and benefits from the world's largest network of no-take reserves. While we know reserves contain more and bigger fish, several key questions about how reserves contribute to sustainable harvesting, protecting biodiversity and resisting climate change remain unanswered. Answers depend on a new understanding of the degree to which fis ....Do marine reserve networks work? Larval connectivity, sustainable harvesting and ecological resilience. The Great Barrier Reef is a globally iconic marine ecosystem and benefits from the world's largest network of no-take reserves. While we know reserves contain more and bigger fish, several key questions about how reserves contribute to sustainable harvesting, protecting biodiversity and resisting climate change remain unanswered. Answers depend on a new understanding of the degree to which fish population on different reefs are connected, and whether or not reserve networks help sustain these linkages. This project will use new technologies to measure the transport of fish larvae between reefs, to assess strengths and weaknesses of the reserve network, and examine ways to improve species protection and sustainable harvesting in a changing climate.Read moreRead less
Reconstructing the impact of climate change on Australian native species. This project will explore the impact of past climate change on Australian native animals to identify species and ecosystems at greatest potential risk, and to help predict and minimise the effects of future change.
Forty million Australians: the future of our biodiversity. Many countries have experienced rapid increases in human numbers and natural-resource use. The project will use measured effects on biodiversity from such countries, combined with models of potential changes in Australia's population and climate, to forecast how our biodiversity may be affected up to 2050, and then to plan how to minimize negative impacts.
Habitat fragmentation: critical role in the decline and recovery of coral reef fish biodiversity. Preserving biodiversity in the face of environmental degradation and climate change is the greatest challenge of our time. Although habitat fragmentation is considered a key cause of the current extinction crisis, the effects of changing habitat configuration on species persistence and recovery is almost completely unknown. Coral reefs are among the most diverse and threatened ecosystems on the plan ....Habitat fragmentation: critical role in the decline and recovery of coral reef fish biodiversity. Preserving biodiversity in the face of environmental degradation and climate change is the greatest challenge of our time. Although habitat fragmentation is considered a key cause of the current extinction crisis, the effects of changing habitat configuration on species persistence and recovery is almost completely unknown. Coral reefs are among the most diverse and threatened ecosystems on the planet and this project will provide the first insights into how coral reef fish diversity responds to increased subdivision and isolation of reef habitat. It will identify critical aspects of habitat change that either enhance local diversity or threaten populations with extinction and provide new ecological data to refine conservation strategies.Read moreRead less

Mesophotic coral ecosystems: understanding the reef's hidden biodiversity. This project aims to assess biodiversity at mesophotic depths and evaluate the vulnerability of these deep-water ecosystems to disturbances and environmental change. Mesophotic coral ecosystems (which live at around 30–100 metres in depth) represent an estimated surface area equivalent to that of shallow coral reefs on the Great Barrier Reef (20 000 square kilometres) yet remain largely undocumented (due to their relative ....Mesophotic coral ecosystems: understanding the reef's hidden biodiversity. This project aims to assess biodiversity at mesophotic depths and evaluate the vulnerability of these deep-water ecosystems to disturbances and environmental change. Mesophotic coral ecosystems (which live at around 30–100 metres in depth) represent an estimated surface area equivalent to that of shallow coral reefs on the Great Barrier Reef (20 000 square kilometres) yet remain largely undocumented (due to their relative inaccessibility) and are not considered in conservation planning. The project aims to characterise the intrinsic (i.e. unique biodiversity) and instrumental (i.e. role in shallow reef recovery) values of mesophotic coral reefs. Expected project outcomes may help develop an effective ecosystem-specific management strategy.Read moreRead less

Summary
Ecology of novel coral reef ecosystems. Coral reef ecosystems are changing. Some of these changes are predictable, based on how species respond to climate change. This project will utilise information on species vulnerability to predict what reef ecosystems, including corals, fishes and invertebrates, will look like in the future and how this will affect the benefits we gain from reefs.
