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.

Domestication of blue-banded bees for greenhouse pollination. The tomato industry is currently shifting towards production in greenhouses, which allows climate control and improved pest management. A lack of pollinators is an obstacle to this move. This project will establish protocols for large-scale use of native blue-banded bees as pollinators in greenhouses, especially for tomatoes. Pollination by native bees increases fruit weight by 15%, comparable to the effects of bumblebees used overs ....Domestication of blue-banded bees for greenhouse pollination. The tomato industry is currently shifting towards production in greenhouses, which allows climate control and improved pest management. A lack of pollinators is an obstacle to this move. This project will establish protocols for large-scale use of native blue-banded bees as pollinators in greenhouses, especially for tomatoes. Pollination by native bees increases fruit weight by 15%, comparable to the effects of bumblebees used overseas. Significant economic, environmental and health benefits are expected from this project. The outcome will satisfy an industry need and remove an environmental threat by finding indigenous substitutes for alien bumblebees.Read moreRead less
Co-evolution of sociality and sex allocation: phylogenetic comparative approaches using insects. This project investigates the coevolution of sex allocation and sociality. Although linkage between these two traits has long been conjectured in evolutionary ecology, and numerous studies have investigated species-specific relationships, the question of how these two features interact over evolutionary time has not been examined. Here, we apply phylogenetic comparative approaches to determine wh ....Co-evolution of sociality and sex allocation: phylogenetic comparative approaches using insects. This project investigates the coevolution of sex allocation and sociality. Although linkage between these two traits has long been conjectured in evolutionary ecology, and numerous studies have investigated species-specific relationships, the question of how these two features interact over evolutionary time has not been examined. Here, we apply phylogenetic comparative approaches to determine whether sex allocation strategies have influenced subsequent social evolution. In particular, we extend the notion of parental manipulation to ask whether mothers have been able to use sex allocation to influence alloparental behaviour in their offspring, leading to greater levels of altruism.Read moreRead less

Conservation genetics and socio-ecology of marsupials in fragmented populations of south-eastern South Australia: towards a regional biodiversity management plan. Habitat destruction and fragmentation is causing the decline of many species in native forests of eastern and southern Australia. Our project will investigate the interplay between the human activities of agriculture and forestry and their effects on native forest ecosystems. It will provide new data on the consequences of fragmentati ....Conservation genetics and socio-ecology of marsupials in fragmented populations of south-eastern South Australia: towards a regional biodiversity management plan. Habitat destruction and fragmentation is causing the decline of many species in native forests of eastern and southern Australia. Our project will investigate the interplay between the human activities of agriculture and forestry and their effects on native forest ecosystems. It will provide new data on the consequences of fragmentation to native mammal species in the rural and regional communities of south-east South Australia and western Victoria. It will establish a strong collaborative partnership between two forestry companies, conservation agencies and university conservation biologists to develop strategies to sustainably manage biodiversity in native forests and conserve populations of rare and threatened native mammals species.

Ecological dynamics of parasite infections in reptiles. Australian ecosystems are threatened by new epidemics of diseases and parasites, some local, others from overseas. Examples include the facial tumours of Tasmanian devils and the fungus that threatens many native frog species. To manage these epidemics effectively, we must understand how they spread through animal populations. With better knowledge of how diseases of wildlife spread, we can develop more effective control of those diseases t ....Ecological dynamics of parasite infections in reptiles.

To manage these epidemics effectively, we must understand how they spread through animal populations. With better knowledge of how diseases of wildlife spread, we can develop more effective control of those diseases thereby protecting wildlife species, animal populations and, ultimately, Australian ecology. This project will help to protect our fauna from invasive diseases and contribute to sustaining the biodiversity of the country. Read moreRead less

The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that le ....The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that led to and maintain live birth and the allocation of sex. This will produce new insights into fundamental questions about the evolution of animal reproduction. Our collaborative approach will make Australian thrips and research an international cornerstone in the biology of reproductive evolution.Read moreRead less
Genetic analysis of two distinct reproductive strategies in sexual and thelytokous field populations of an endoparastic wasp. Asexual (thelytokous) females of an insect parasitoid, Venturia canescens, which develop inside another insect, exhibit evolutionarily stable mixtures of life-history strategies, allowing two genetically distinct wasp lines to coexist sympatrically on the same host resources. The two thelytokous lines differ in a virus-like particle protein-coding gene (VLP1), which raise ....Genetic analysis of two distinct reproductive strategies in sexual and thelytokous field populations of an endoparastic wasp. Asexual (thelytokous) females of an insect parasitoid, Venturia canescens, which develop inside another insect, exhibit evolutionarily stable mixtures of life-history strategies, allowing two genetically distinct wasp lines to coexist sympatrically on the same host resources. The two thelytokous lines differ in a virus-like particle protein-coding gene (VLP1), which raises the question whether the VLP1 gene locus is genetically associated with the phenotype. We will investigate the genetic basis for the observed phenotypic differences, by comparing the two thelytokous lines with the corresponding homozygous VLP1-genotypes in sexual strains. The outcome will provide a molecular and genetic framework to test parthenogenetic reproduction strategies in some insect species.Read moreRead less
LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to in ....LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to influence debate in this central area of behavioural ecology. We will also produce new information on behavioural ecology of Australian fauna, important for conservation management and ecotourism.Read moreRead less
