Early warning of cyanobacteria blooms in drinking water reservoirs by means of evolutionary algorithms. 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 bloo ....Early warning of cyanobacteria blooms in drinking water reservoirs by means of evolutionary algorithms. 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
Sea Snake Diversification: Why Are Certain Taxa And Regions Species-Rich? 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 ben ....Sea Snake Diversification: Why Are Certain Taxa And Regions Species-Rich? 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.

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
