Summary
Investigating the susceptibility of native vegetation edges to alien plant invasion: a quantitative study to help prevent and control invasive species. Alien plant invasion is a major threat to biodiversity in national parks and nature reserves. Determining the relative influence of plant characteristics, number of alien plant seeds and availability of light, water and nutrients on weed invasion will indicate what prevention and control strategies should be used to combat invasive plants.
How complex species interactions mediate plant community diversity. This project aims to manage and protect biodiversity under global change by adding biological realism to mechanistic diversity models. Species interactions are central to understanding biodiversity at local to regional scales. Most diversity models assume that direct competition captures all salient details of species interactions, while more complex species interactions are unimportant. This unsupported, pervasive assumption ha ....How complex species interactions mediate plant community diversity. This project aims to manage and protect biodiversity under global change by adding biological realism to mechanistic diversity models. Species interactions are central to understanding biodiversity at local to regional scales. Most diversity models assume that direct competition captures all salient details of species interactions, while more complex species interactions are unimportant. This unsupported, pervasive assumption has major consequences for how diversity is predicted and explained. This study will combine field experiments on plant species’ responses to climate and land use changes with a modelling framework. Expected outcomes include improving the ability to manage invasive species and to protect biodiversity under conditions of global environmental change.Read moreRead less
Revealing how top predators maintain healthy balanced ecosystems. Large predators play a pivotal role in maintaining healthy, balanced ecosystems. This project will reveal how Australia's largest predator, the dingo, provides ecosystem services and benefits biodiversity.

Summary
Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, ....Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, to discover symptoms of declining ecosystems and find robust metrics that diagnose change in networks of co-occurring species. The intended outcome is to clarify the relationship between species interactions, co-occurrence and ecosystem decline, knowledge critical to ecosystem recovery.Read moreRead less
