Fauna in Australian ecosystems are threatened by habitat fragmentation, changing environments and the spread of exotic pathogens. To manage these threats we need to understand the behavioural flexibility of wildlife populations. This project focuses on how individual behavioural differences can influence social networks and consequently pathogen transmission. It will help to protect our fauna from invasive diseases and contribute to sustaining biodiversity. With better knowledge of how diseases spread we can develop more effective controls of those diseases, thereby protecting wildlife species, animal populations and Australian ecosystems.

Fish flukes (flatworm parasites) with direct lifecycles can weaken and kill captive fish and threaten lucrative industries like finfish aquaculture and public aquaria in Australia and globally. Traditional approaches and molecular techniques will identify monogenean flukes in a family containing known pathogenic species distributed worldwide. Knowledge of fish disease is paramount for quarantine, risk assessments for import/export and for managing pathogen outbreaks in aquaculture. Benefits include: economic/social improvements in regional/rural Australia where fish farms are expanding; international excellence and core research training in fish parasitology; profitable, exportable expertise; knowledge of endemic and shared pathogens.Read moreRead less

Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damagin ....Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damaging objects and substances. We use insect plasma to dissect recognition and inactivation of damaging objects and substances with the aim to understand tolerance and its inhibition to design novel strategies in delaying tolerance to pesticides in insect pests.Read moreRead less
The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establ ....The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establish a detailed phylogeny for Serpulidae and assess the evolution of larvae in the group. If feeding larvae are shown to be secondary this will raise doubts about established theories of animal evolution.Read moreRead less

Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale. This Network aims to bring together a diverse spectrum of highly experienced and early career researchers to pool their ideas and expertise to allow them to determine how best to describe Australia's current biodiversity and the biological and environmental history leading up to the present. A major outcome will be the ability to predict the impacts of environmental change on biodiversity to assist management decisions across Australia, with lessons of global importance.Read moreRead less

A stopped-flow spectroscope is requested that can capture the rapid kinetics of changes in conformation of biopolymers, macromolecules and chiral catalysts as they interact with other molecules. This includes measurement of rapid transport of solutes through membrane proteins in lipid membranes. The versatile instrument can also determine circular dichroism spectra of peptides, proteins, tannins, pigment complexes and chiral catalysts that is required within several existing collaborations to understand the tertiary structures, stability and interactions between the complex molecules. The instrument will significantly strengthen research on macromolecules and polymers that have applications in the wine industry, nanotechnology, and biotechnology.Read moreRead less
Evolution of host relationships among the parasitic wasps inferred from morphology, DNA sequences and mitochondrial genome organisation.

The parasitic Hymenoptera (wasps) are extensively used as biological control agents of agricultural and horticultural pests worldwide, but detailed information on their evolutionary relationships, how they have coevolved with major host groups, and the patterns of host relationships across various wasp families are lacking. This project will employ DNA sequence data from 'new' genes, information on mitochondrial genome organisation, as well as morphology, to generate robust phylogenies for braconid and scelionid wasps that can be used to determine patterns of host utilisation and predict hosts for wasp groups where this information is currently unknown.Read moreRead less
