Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers throu ....Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers through a series of experiments. The expected outcome of this project is a clear understanding of the role of traits in wood decomposer communities, especially their influence on priority effects, competitive hierarchies, and the resultant wood decay rate.Read moreRead less
Why are complex habitats more diverse? This project aims to develop and test theory for the ubiquitous relationship between habitat complexity and biodiversity. Whether in forests, grasslands, kelp forests or coral reefs, habitat complexity is increasingly being flattened by natural and human-based processes. The project will integrate novel three-dimensional habitat models with established ecological theory, and then validate the theory on coral reefs that have undergone disturbances with diffe ....Why are complex habitats more diverse? This project aims to develop and test theory for the ubiquitous relationship between habitat complexity and biodiversity. Whether in forests, grasslands, kelp forests or coral reefs, habitat complexity is increasingly being flattened by natural and human-based processes. The project will integrate novel three-dimensional habitat models with established ecological theory, and then validate the theory on coral reefs that have undergone disturbances with different effects on complexity (cyclones and bleaching). This project will significantly advance the predictive capacity of biodiversity risk assessments of these threatened ecosystems and potentially others worldwide.Read moreRead less

Summary
Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollinati ....Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollination ecology. This project will quantitatively assess the effectiveness of pollinator communities to determine the importance of pollinator community composition to maximising crop production. This project is expected to protect food resources and economically benefit Australia.Read moreRead less
Keystone effects of Australia's top predators: dingoes, devils and biodiversity. This project will study the interactions of Australia's two largest predators, the dingo and Tasmanian devil, with other species. The project will help develop an understanding of the value of these predators in maintaining ecosystem processes and diversity, and guide their management in the future.
The legacy of rainfall patterns in dryland ecosystems. This project aims to use an experimental approach to determine how rainfall regime structures dryland communities and ecosystem properties and potential responses to altered rainfall regime. Ecosystem functioning in drylands is governed by complex interactions between microbes, invertebrates and plants. Biological activity however is constrained by the availability of water and altered rainfall regimes that could moderate how organisms inter ....The legacy of rainfall patterns in dryland ecosystems. This project aims to use an experimental approach to determine how rainfall regime structures dryland communities and ecosystem properties and potential responses to altered rainfall regime. Ecosystem functioning in drylands is governed by complex interactions between microbes, invertebrates and plants. Biological activity however is constrained by the availability of water and altered rainfall regimes that could moderate how organisms interact, potentially causing trophic cascades and even ecosystem state changes. By linking observed responses with soil microbial functional attributes using newly developed molecular techniques the project seeks to provide a mechanistic insight into ecosystem responses to climate variability and extreme climatic events.Read moreRead less
Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. ....Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. Whilst these changes often involve degradation from productive states, we have a poor understanding of the mechanisms which drive change. Key stressors in marine systems, OA and warming are predicted to drive loss of kelp forests but we still don't understand the reality of these predictions.Read moreRead less
Designing green spaces for biodiversity and human well-being. Designing green spaces for biodiversity and human well-being . This project aims to determine mechanisms linking urban design to socio-ecological benefits from green spaces. Ecological restoration in urban green space could attract more biodiversity into urban environments, reduce maintenance costs, provide market advantage for the development industry and improve a sense of place for residents.

This project aims to determine mechanisms linking urban design to socio-ecological benefits from green spaces. Ecological restoration in urban green space could attract more biodiversity into urban environments, reduce maintenance costs, provide market advantage for the development industry and improve a sense of place for residents. However, how best to encourage biodiversity using urban design is poorly understood, and little is known about how green spaces create health and well-being. This project will alter levels of green space design explanatory variables in modular experimental plots, in both Royal Park, the City of Melbourne’s largest public green space, and Melbourne’s CBD; conduct biodiversity and human wellbeing experiments; and develop urban design recommendations that support biodiversity and human wellbeing.Read moreRead less
Temperate trophic cascades: impacts of seal foraging on benthic community dynamics. Effective Marine Protected Area management across Australia requires guidance from rigorous strategic research. The project will investigate opposing activities that provoke ecosystem collapse (overharvesting, grazing) or recovery (marine park protection) and provide advice to improve effectiveness of marine conservation strategies in New South Wales and South Australia.

The aim is to develop flexible models for the analysis of high-dimensional count data, in particular, for studying species interactions and the response of communities to environmental factors. This project is significant because increasingly, important research questions are answered using data with many response variables, with a particular need when studying ecological communities and their response to environmental impacts. This project aims to develop the first models that can be used directly to draw valid community-level conclusions for common ecological data types. The expected outcome is a powerful toolset for fully model-based inference from high-dimensional counts, introducing modern approaches to a high-impact area of ecology.Read moreRead less

This project aims to quantify the species traits and environmental conditions that enable wildlife to persist in an increasingly urbanised world. Through developing and testing a framework linking unprecedented urban expansion and biodiversity change, this project will identify favourable conditions that support biodiversity in the face of global urbanisation. Project outcomes will inform appropriate real-world management actions and equip scientists, policy-makers and planners with tools to forecast the persistence of biodiversity in Australian cities. By discovering the attributes species need to survive city life this project will help prevent future catastrophic declines of global biodiversity in our increasingly urbanised world.Read moreRead less
