Increased climatic variability and human-induced environmental degradation have had severe impacts on biodiversity, socio-economic sustainability and possibly our own future survival, thus attracting global attention. This study will help unravel the causes of the extinctions of Australia's large-size animals (megafauna) during the periods of last glaciation and earliest human colonisation of Australia. Investigating the causes of megafauna extinction is essential for an understanding of how those prehistoric events shaped the modern biota, and for the development of conservation strategies for our endemic faunas in an era of increased climatic and environmental variability and vulnerability.Read moreRead less

Climate change and phenotypic divergence at a landscape scale. Birds provide key ecosystem functions like pollination, insect control, and seed dispersal in Australia. Climate change is well documented and has a pronounced effect on birds, commonly leading to range shifts. This study will quantify patterns of gene flow at a landscape scale in declining and common birds in Australia and abroad. The project builds on strong international links to the Galapagos Islands as well as a regional focus f ....Climate change and phenotypic divergence at a landscape scale. Birds provide key ecosystem functions like pollination, insect control, and seed dispersal in Australia. Climate change is well documented and has a pronounced effect on birds, commonly leading to range shifts. This study will quantify patterns of gene flow at a landscape scale in declining and common birds in Australia and abroad. The project builds on strong international links to the Galapagos Islands as well as a regional focus for South Australia. The linkage organisations are committed to implementing management outcomes for native flora and fauna, which need to be underpinned with quality baseline data. The outcomes will also inform climate modelling for the State and Australia. Read moreRead less
Understanding responses to climate change: a mechanistic approach integrating functional genetics, physiology and biophysical models for the Common brown butterfly. We will dissect the interaction between an Australian butterfly and changing climate.

We will dissect the interaction between an Australian butterfly and changing climate. This will make significant contributions to the national research priorities Responding to climate change and variability and Sustainable use of Australia's biodiversity. We will address the known deficits in standard approaches to predicting futures for biota. We will provide an Australian species in which the mechanisms of response to climate change are understood in detail. Our outputs will be directly applicable to other butterflies: 19 threatened taxa in Australia. The novelty of our approach will be of marked international interest, and will train Australian researchers in a new way of predicting biological impacts of climate change.Read moreRead less
Winter Foraging Locations Of Southern Ocean Predators In Relation To Stochastic Variation In Sea-Ice Extent. Antarctic marine communities are likely to be amongst the first anywhere to show changes due to climate change. A top national priority for Australia is to understand how Antarctic communities will be affected if climate change does occur. As predators reflect changes occurring lower in the food chain, these are an important group to study. This study will be the first to specifically lin ....Winter Foraging Locations Of Southern Ocean Predators In Relation To Stochastic Variation In Sea-Ice Extent. Antarctic marine communities are likely to be amongst the first anywhere to show changes due to climate change. A top national priority for Australia is to understand how Antarctic communities will be affected if climate change does occur. As predators reflect changes occurring lower in the food chain, these are an important group to study. This study will be the first to specifically link ice extent with the habitat use of predators, and quantify how this varies over time. Some work already indicates that there have been community level changes in some predators in the Antarctic due to changes in ice extent, so developing tools to predict the nature and magnitude of these changes are needed.

Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change ....Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change Action Plan (2004-2007). The proposed research will assess exotic plant species' responses to climate change, identify potential hotspots of invasion, and provide a risk assessment framework to enable prioritization of exotic plant management under future climate.Read moreRead less

Summary
High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of ....High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of N analyses. The equipment we are requesting - a LECO combustion analyser, allows us to analyse samples quickly and safely and uses fewer chemicals and much less water than do traditional machines.Read moreRead less

Our research, which focuses on the world's most recently discovered, fossil-rich amber deposit will significantly increase this value. In addition to discovery of hundreds of stunningly-well preserved fossil organisms, analysis of trapped bubbles of ancient air will enable us to reconstruct their prehistoric environment. This should improve ability to anticipate biotic responses to future climate change. The amber industry globally contributes to national wealth. Increasing understanding about the geology and palaeontology of this amber deposit will maximise commercial and scientific benefits to the nation.Read moreRead less
Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that clim ....Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that climate change was to blame. This study will refine our knowledge of the timing and causes of these extinctions in southern Australia by assessing how communities responded to climate change in the lead-up to human arrival. It will provide vital information for managing the conservation of many modern species and guide us in limiting future losses.Read moreRead less
