Testing indicators of genetic exchange and adaptation of populations, essential for biodiversity assessment and management. There will be diverse benefits from our testing and improvement of genetic indicators for exchange between populations and adaptive differentiation of populations. Managers and population biologists will have confidence in choice and use of these vital tools in sustainable use of our terrestrial and aquatic bioresources, as recommended by the federal State of Environment s ....Testing indicators of genetic exchange and adaptation of populations, essential for biodiversity assessment and management. There will be diverse benefits from our testing and improvement of genetic indicators for exchange between populations and adaptive differentiation of populations. Managers and population biologists will have confidence in choice and use of these vital tools in sustainable use of our terrestrial and aquatic bioresources, as recommended by the federal State of Environment system. Also, the use of these tools to identify differential genetic adaptations is the first step in bioprospecting, as well as revealing the raw material for natural and artificial populations to adapt to changes: soil loss, salinity, acidity, climate change. Forensic genetics will benefit from the improved tools for defining subpopulations.Read moreRead less
Intersexual arms races - are individuals within marine meta-populations less able to interbreed than assumed? A meta-population structure is thought to describe the inter-connected nature of many populations of marine animals with dispersive larvae. However, new theory predicts some of these populations might be not very inter-connected at all, despite larval migration. In some circumstances, independent, co-evolutionary arms races between sexes might develop within local populations, resulting ....Intersexual arms races - are individuals within marine meta-populations less able to interbreed than assumed? A meta-population structure is thought to describe the inter-connected nature of many populations of marine animals with dispersive larvae. However, new theory predicts some of these populations might be not very inter-connected at all, despite larval migration. In some circumstances, independent, co-evolutionary arms races between sexes might develop within local populations, resulting in individuals becoming increasingly less able to interbreed freely. I will directly test for this, measuring how successfully broadcast spawners can cross-fertilise across populations. This will reveal the genetic structure of these populations and if these animals really do live in a meta-population.Read moreRead less
Population growth, genetic variation and adaptation in two Caulerpa species in southeastern Australia. This project will examine factors that influence the population growth, reproduction, genetic variation and adaptation in two seaweeds; the invasive Caulerpa taxifolia and the possibly invasive C. filiformis. A combination of surveys, modelling, molecular genetics and field experiments will be undertaken to achieve this. The current ambiguity surrounding the status of C. filiformis as an inva ....Population growth, genetic variation and adaptation in two Caulerpa species in southeastern Australia. This project will examine factors that influence the population growth, reproduction, genetic variation and adaptation in two seaweeds; the invasive Caulerpa taxifolia and the possibly invasive C. filiformis. A combination of surveys, modelling, molecular genetics and field experiments will be undertaken to achieve this. The current ambiguity surrounding the status of C. filiformis as an invasive species in Australia will be addressed by comparing DNA sequences of Australian and African plants. This project will provide critical data for managing invasive species, but more broadly, increase the current understanding of their biology and the factors important in their population growth and adaptation.Read moreRead less
Ageing wild vertebrates from their DNA: an investigation using Humpback Whales as an example. The aim of this project is to estimate the age of individually identified humpback whales and the age structure of humpback whale populations using non-lethal, innovative molecular techniques. Populations of humpback whales in the Southern Hemisphere are slowly recovering from intensive whaling during the 20th century. This project is significant because it will provide the first comparative information ....Ageing wild vertebrates from their DNA: an investigation using Humpback Whales as an example. The aim of this project is to estimate the age of individually identified humpback whales and the age structure of humpback whale populations using non-lethal, innovative molecular techniques. Populations of humpback whales in the Southern Hemisphere are slowly recovering from intensive whaling during the 20th century. This project is significant because it will provide the first comparative information on the age structure of these populations, resulting in improved estimation of recovery and population dynamics of long-lived vertebrates. The results of this project will revolutionise research on ageing in whales and dolphins, providing an important alternative to lethal scientific whaling.Read moreRead less
