Bringing back Australia's lost woodland biodiversity: towards strategic multi-species reintroductions. Australia has the highest rate of mammal extinction of any continent on the planet. This has reduced biodiversity and compromised many important ecological processes. What is the best way to re-build depauperate mammal communities with multi-species reintroductions? What effects do multi-species reintroductions have on recipient ecosystems? This project aims to explore these questions by reintr ....Bringing back Australia's lost woodland biodiversity: towards strategic multi-species reintroductions. Australia has the highest rate of mammal extinction of any continent on the planet. This has reduced biodiversity and compromised many important ecological processes. What is the best way to re-build depauperate mammal communities with multi-species reintroductions? What effects do multi-species reintroductions have on recipient ecosystems? This project aims to explore these questions by reintroducing three mammal species to a critically endangered temperate woodland: a carnivore (the eastern quoll), an insectivore (yellow-footed antechinus), and a herbivore (the eastern chestnut mouse). Results from this sequenced multi-species reintroduction experiment will have broad applicability to ecosystem restoration in Australia and overseas.Read moreRead less
Reintroduction of ecosystem engineers as a woodland restoration tool. Can we help restore woodlands by reintroducing extinct native mammals? Through a strategic partnership combining innovative research and conservation action, this project will investigate how returning extinct 'ecosystem engineers' could be used as a tool for restoring healthy temperate woodland ecosystems.
Conservation of tropical forests for their carbon and biodiversity values. International efforts to save tropical forests for the carbon they store could help mitigate climate change and biodiversity loss. This project will aid these efforts by developing methods to model future deforestation and extending decision theory for the new challenges presented by international carbon-payment schemes.
The ecology of parasite transmission in fauna translocations. Parasitic diseases pose a threat to the conservation management of Australia's biodiversity. This project will improve our understanding of the impact and transmission of parasites in fauna translocations, contributing to the conservation management of Australian ecosystems by government and private agencies.
Accelerating species richness gains and carbon sequestration in secondary regrowth in north Queensland. Tropical abandoned lands offer important opportunities to increase carbon storage and conserve biodiversity. However, natural forest regeneration is slow and frequently inhibited by woody weeds. The project will involve a collaboration between eminent tropical biologists and the carbon-industry to devise innovative strategies to accelerate restoration of degraded land.
Ecosystem quality and herbivore dynamics in tropical rainforests fragmented by deforestation. After logging, large expanses of south-east Asian rainforests are being converted to oil palm plantations. This is occurring within a mega-diverse area of global ecological and conservation significance yet the ecological consequences of this process are poorly understood. This project will examine patterns of changes in key arthropod herbivores, their food resources and natural enemies within experimen ....Ecosystem quality and herbivore dynamics in tropical rainforests fragmented by deforestation. After logging, large expanses of south-east Asian rainforests are being converted to oil palm plantations. This is occurring within a mega-diverse area of global ecological and conservation significance yet the ecological consequences of this process are poorly understood. This project will examine patterns of changes in key arthropod herbivores, their food resources and natural enemies within experimentally fragmented post-logging forests. The project will quantify the effects of fragment size, location and vegetation upon the herbivore dynamics, their impact on the vegetation and their interactions with their natural enemies. The project aid understanding the dynamics of the ecosystems involved and the services they provide.Read moreRead less

Summary
Using big data to untangle ecological cascades in tropical forests. This project aims to develop a suite of innovative analysis techniques to study wildlife communities with remarkable resolution. This project expects to generate new knowledge in the fields of ecology and conservation biology by leveraging the unprecedented quantity and quality of data captured through a large network of camera traps in Australian and Southeast Asian forests. Expected outcomes include developing novel approaches ....Using big data to untangle ecological cascades in tropical forests. This project aims to develop a suite of innovative analysis techniques to study wildlife communities with remarkable resolution. This project expects to generate new knowledge in the fields of ecology and conservation biology by leveraging the unprecedented quantity and quality of data captured through a large network of camera traps in Australian and Southeast Asian forests. Expected outcomes include developing novel approaches to analysing wildlife data (meta-structural equation modelling) and delivering management guidance to Australian land-owning agencies that may vastly cut costs by identifying efficient interventions and improve conservation outcomes.

Development of a safe and immunogenic anti-chlamydia vaccine for the koala. Many koala populations are under threat of extinction from chlamydial disease.The project will develop a chlamydial vaccine and conduct trials in several wild koala populations for safety and effectiveness.
Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air insi ....Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air inside leaves based on stable isotope analysis of carbon dioxide and water vapour exchanged between leaves and air. The project is expected to provide fundamental knowledge about how stomata regulate photosynthesis and water use, with significant implications for modelling vegetation function and for improving the performance of crop plants.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
