This project will enhance woodland management in inland NSW by: (1) advancing our understanding of factors controlling woodland dynamics and (2) refining predictions of the effects of landuse scenarios on long-term vegetation dynamics. Outcomes will assist policy development and on-ground decision making by natural resource managers. Results will be used by managers of biodiversity, salinity, erosion, tree clearing, silviculture, rehabilitation and protected areas. Our findings will reduce conflicting perceptions about past and future vegetation changes in regional areas, thereby advancing uptake of sustainability plans to ensure long-term social, economic and environmental benefits for an environmentally sustainable Australia.Read moreRead less
Mistletoe as a keystone resource---an experimental test. My recent synthesis of known interactions between animals and mistletoe suggests that mistletoe functions as a keystone resource, influencing diversity patterns in forested ecosystems worldwide. This project tests the keystone hypothesis explicitly for woodland communities using landscape-scale manipulation. In 40 woodland remnants, all mistletoes will be removed from 20, with subsequent seasonal censuses of woodland birds, arboreal mars ....Mistletoe as a keystone resource---an experimental test. My recent synthesis of known interactions between animals and mistletoe suggests that mistletoe functions as a keystone resource, influencing diversity patterns in forested ecosystems worldwide. This project tests the keystone hypothesis explicitly for woodland communities using landscape-scale manipulation. In 40 woodland remnants, all mistletoes will be removed from 20, with subsequent seasonal censuses of woodland birds, arboreal marsupials and butterflies. Incorporating data on spatial and temporal variation in fruit, nectar and arthropod availability, this study represents a model system for understanding the ecosystem-wide role of ecological keystones and the influence of resource distribution on diversity patterns in fragmented habitats generally.Read moreRead less

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?

Predicting climate change impacts on biodiversity: testing and applying new approaches. A primary challenge faced by Australia is predicting the threat that climate change will have on biodiversity. This project will dramatically improve our ability to manage threats to biodiversity posed by climate change by studying plant species at warmer latitudes, where they are already experiencing predicted future climate conditions.
Does coevolution or ecological context determine predator-prey coexistence? This project aims to deliver the first robust evaluation of the evolutionary and ecological conditions that combine to enable introduced predators to drive extinctions of native mammals. The project will bring together disciplines of invasion biology and trophic cascades to model predator-prey systems in the presence and absence of apex predators. This globally unique study will provide an informed and transparent toolse ....Does coevolution or ecological context determine predator-prey coexistence? This project aims to deliver the first robust evaluation of the evolutionary and ecological conditions that combine to enable introduced predators to drive extinctions of native mammals. The project will bring together disciplines of invasion biology and trophic cascades to model predator-prey systems in the presence and absence of apex predators. This globally unique study will provide an informed and transparent toolset for preventing decline of threatened species and will enhance Australian conservation policy by untangling contrasting perspectives of introduced predators and the conditions that lead to native species extinction.Read moreRead less
The return of the native: reintroductions, reinvasions, and a new paradigm in restoration ecology. We develop a new solution to improve pest control used to protect rare and endangered wildlife by using reintroductions of common native species as a block to reinvasion following pest control. Our approach will significantly reduce the ongoing costs of pest control in Australia and our solution can be used by both large conservation organisations as well as small community groups aiming to control ....The return of the native: reintroductions, reinvasions, and a new paradigm in restoration ecology. We develop a new solution to improve pest control used to protect rare and endangered wildlife by using reintroductions of common native species as a block to reinvasion following pest control. Our approach will significantly reduce the ongoing costs of pest control in Australia and our solution can be used by both large conservation organisations as well as small community groups aiming to control pests and protect key wildlife. Our technique can also be exported to solve alien species problems elsewhere in the world. This work strengthens Australia’s world renowned expertise for research into alien species and ability to develop novel solutions to alien impacts.Read moreRead less

Small but bold: harnessing microbes to boost drought tolerance in grasses . Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses.

Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses. Yet, to harness this potential, we first need to identify the key microbial functions that contribute to plant tolerance to drought. This project aims to determine the microbe-mediated ecological and functional mechanisms that underpin grass performance under drought. This knowledge will lay the foundation to accelerate the design and implementation of effective microbial manipulations and management strategies, and thus increase our success in protecting this important ecosystem.Read moreRead less
Ecological forecasts of species response to fire, drought and heatwaves. This project will advance ecosystem forecasting by accounting for how legacy effects from extreme environmental events – prolonged droughts, floods, heatwaves and fires – persist into future years in vulnerable dryland ecosystems. As highly stressed environments are expected to leave increasingly large impacts on flora and fauna and exacerbate desertification, answers are urgently needed to understand and mitigate these imp ....Ecological forecasts of species response to fire, drought and heatwaves. This project will advance ecosystem forecasting by accounting for how legacy effects from extreme environmental events – prolonged droughts, floods, heatwaves and fires – persist into future years in vulnerable dryland ecosystems. As highly stressed environments are expected to leave increasingly large impacts on flora and fauna and exacerbate desertification, answers are urgently needed to understand and mitigate these impacts. This project will foster new appreciation of ecosystem features that build resilience to change, or that lead to collapse. Benefits include better forecasting tools to manage ecosystems at risk, improved security of biodiversity and food production in Australian rangelands, and training of early career researchers.Read moreRead less
Integrating the rice industry with biodiversity conservation: the spatial ecology of waterfowl in agricultural and natural landscapes. Waterfowl damage to rice crops is a significant problem for the rice industry worldwide. The management and conservation of waterfowl requires an explicit understanding of the effect of rice bays on habitat structure for waterfowl and how these interact with population processes operating at broad scales. This project will analyse the spatial ecology of waterfowl ....Integrating the rice industry with biodiversity conservation: the spatial ecology of waterfowl in agricultural and natural landscapes. Waterfowl damage to rice crops is a significant problem for the rice industry worldwide. The management and conservation of waterfowl requires an explicit understanding of the effect of rice bays on habitat structure for waterfowl and how these interact with population processes operating at broad scales. This project will analyse the spatial ecology of waterfowl in agricultural and natural landscapes in the Murray-Darling Basin. Specifically we will (1) track waterfowl, (2) analyse wetland distribution at fine and broad scales, (3) develop spatial models to describe the relationships between waterfowl movements and wetland distribution, including rice bays, and (4) develop models of agronomic risk based on landscape structure and the known responses of waterfowl.Read moreRead less

Conserving and recovering the koala populations on NSW Far North Coast. This project aims to develop a novel, integrated socio-ecological approach for connecting landscapes and communities for the recovery of threatened koala populations on the New South Wales far north coast. This should increase understanding of how local landholders and land managers respond to koala recovery programs and why they respond positively and become engaged for the long-term. The intended outcome is a spatial prioritisation framework for species recovery that integrates social and ecological values, and increased global knowledge of how to recover declining wildlife populations.Read moreRead less
