Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosys ....Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.Read moreRead less

Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding ....Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding, prey manipulation and the role of critical senses in the only captive population of sawfishes in Australia. Such knowledge will underpin the development and use of visual, chemical and/or magnetic repellents by fisherman that are still responsible for the loss of large numbers of sawfish as by-catch.Read moreRead less
Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance.

The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This project plans to use plant functional traits related to nutrient and water acquisition to predict plant community assembly under different soil resource availabilities and thus assist in successful rehabilitation of this native vegetation after closure of sand-mining operations.Read moreRead less

Regime shifts from kelp forests to turfs: drivers, resilience and future. This project aims to apply a comparative experimental and analytical approach to quantify linkages among multiple stressors driving kelp forest loss and expansion of turfs across three continents. Transformations of kelp forests to turf reefs are associated with a profound loss of ecological productivity and function, with significant impacts for societies reliant on the biodiversity and functioning of kelp ecosystems.

This project aims to apply a comparative experimental and analytical approach to quantify linkages among multiple stressors driving kelp forest loss and expansion of turfs across three continents. Transformations of kelp forests to turf reefs are associated with a profound loss of ecological productivity and function, with significant impacts for societies reliant on the biodiversity and functioning of kelp ecosystems. Field and laboratory experiments will be used to develop and test ‘green gravel’, a novel restoration tool that aims to overcome reinforcing feedbacks (lack spores and hard substrate) preventing recovery of kelp forests. This will provide significant benefits by identifying solutions to address loss of kelp forests in Australia and globally.Read moreRead less

This fellowship aims to resolve carbon removal and nutrient mitigation potential of Australia’s kelp forests now and in future. It will create new understanding of the ecosystem services provided by the Great Southern Reef, and the capacity of kelp forests to provide nature-based solutions to reduce emissions and improve coastal water quality. Using a combination of global models and ecological experiments on kelp forests and their replacement ecosystem states, the fellowship will predict changes in function with warming. This information is critical to determine net ecosystem mitigation potential and will significantly advance our understanding of the potential of kelp forests to generate co-benefits while conserving biodiversity.

The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less

This project aims to examine the process of ecosystem re-assembly on land which is taken out of agricultural production and left without further management. Land abandonment is common in many parts of the world and could increase dramatically in Australia due to land degradation, salinity and structural change. We will investigate the factors which influence whether native plant species can recolonise abandoned farmland, using field and greenhouse studies. We will do this within the context of ecosystem assembly, thereby answering a practical question and also providing input to a conceptual area which is currently of great interest inRead moreRead less
