New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ec ....New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ecogenomics offers a way to rapidly assess the composition of an ecological community. These techniques offer great promise, but they must be cross-validated against existing methods to derive the best ’toolbox’. Working with Melbourne Water and CSIRO the investigators aim to do this using demonstration estuaries in Victoria.Read moreRead less
Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less

Summary
Linking changes in plant-pollinator networks to plant reproduction. The project aims to investigate how human actions in agricultural landscapes affect the activity of pollinating insects and the consequence for the plants that rely on them for reproduction. The project seeks to reveal how the structure of plant-pollinator networks is related to the reproductive success of plants through the novel application of networks that describe patterns in species interactions. The knowledge gained from t ....Linking changes in plant-pollinator networks to plant reproduction. The project aims to investigate how human actions in agricultural landscapes affect the activity of pollinating insects and the consequence for the plants that rely on them for reproduction. The project seeks to reveal how the structure of plant-pollinator networks is related to the reproductive success of plants through the novel application of networks that describe patterns in species interactions. The knowledge gained from this study will enhance our ability to forecast the effects of insect declines for plant seed production in Australia and the world. The intended benefit is an improved capacity to identify vulnerable plant species and maintain pollination services in managed landscape for both wild and cultivated plant populations.Read moreRead less
Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeologi ....Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.

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
