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

Estimated economic cost of cyanobacteria blooms to Australia are at $150 million p.a. Early warning for cyanobacteria blooms will inform water managers to conduct preventive and operational control in reservoirs and water works, and significantly lower risks for public health and costs for monitoring and treatment. Resulting early warning systems will be novel prototypes for cyanobacteria blooms in drinking water reservoirs based on forecasting models adaptable to environmental and climate change. Model-based scenario analysis will also assist in informed decisions on effects of drought, injection of recycled water and global warming to cyanobacteria growth.Read moreRead less
Sulfur cycling in soil environments - how bacteria contribute to the oxidation of organic and inorganic sulfur compounds. Element cycling in soil environments is of global significance as soils constantly exchange compounds with the atmosphere and cover vast areas of land. Many of the compounds exchanged are known contributors to the greenhouse effect and other phenomena such as acid rain. By elucidating the regulation of bacterial sulfur oxidation pathways and their integration into general met ....Sulfur cycling in soil environments - how bacteria contribute to the oxidation of organic and inorganic sulfur compounds. Element cycling in soil environments is of global significance as soils constantly exchange compounds with the atmosphere and cover vast areas of land. Many of the compounds exchanged are known contributors to the greenhouse effect and other phenomena such as acid rain. By elucidating the regulation of bacterial sulfur oxidation pathways and their integration into general metabolism, we will enable the development of better management strategies for agricultural soils. Our data will also significantly improve understanding of how soil processes will change in response to changing climatic conditions.Read moreRead less

By generating new knowledge of ecologically and medically important Australasian organisms, this project will benefit biodiversity management, snakebite therapy and pharmaceutical research. Sea snakes reach peak diversity in the Indo-Australian hotspot and are threatened by habitat degradation, fisheries bycatch and rising sea temperatures. Sea snake conservation and marine reserve management strategies will directly benefit from a better understanding of local endemism, species boundaries and possible cryptic species. Sea snakes are highly venomous and pose a significant health risk in fishing communities; venom variation has a strong phylogenetic component and is of vital importance in antivenom preparation and bioprospecting.

Mechanisms of plant species co-existence in species-rich ecosystems: testing hypotheses using spatially-explicit field data and computer models. A generally accepted explanation for the co-existence of species in high diversity communities is one of the outstanding unresolved issues in ecology. Current hypotheses fail to satisfy in their generality; spatial implications are inadequately explored empirically, and the hypotheses are not testable within a common framework. Advances in spatial analy ....Mechanisms of plant species co-existence in species-rich ecosystems: testing hypotheses using spatially-explicit field data and computer models. A generally accepted explanation for the co-existence of species in high diversity communities is one of the outstanding unresolved issues in ecology. Current hypotheses fail to satisfy in their generality; spatial implications are inadequately explored empirically, and the hypotheses are not testable within a common framework. Advances in spatial analysis and complex system modelling now make the search for a general explanation feasible. This project will parameterise and test the different co-existence hypotheses using spatial statistics, empirical/experimental studies of dispersal, recruitment, competition and herbivory, and spatially-explicit computer simulation models of community assemblage in species-rich Australian shrubland communities.Read moreRead less
Postgenomic perspectives on human nature. The rapid growth of biological knowledge and the need for societal reflection on this knowledge and its applications in Australia and overseas make it increasingly urgent that the humanities and social sciences draw on a biologically credible vision of human nature.

The rapid growth of biological knowledge and the need for societal reflection on this knowledge and its applications in Australia and overseas make it increasingly urgent that the humanities and social sciences draw on a biologically credible vision of human nature. We will study how non-scientists understand human nature and compare their ideas to those of scientists from a range of different disciplines. We will examine what current biology reveals about the biological basis of human characteristics and develop an account of human nature that is defensible in the light of that knowledge.Read moreRead less
