Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less
Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale.

An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed natural vegetation. The project moves measures of restoration success beyond that of population establishment and survival to incorporate the evolutionary processes that provide long-term resilience, persistence and functional integration of restored populations into broader landscapes.Read moreRead less

Designing for uncertainty in conservation auctions. Economic theory and case study evidence show that tenders or auctions are more efficient than grant mechanisms for encouraging landholders to produce environmental outcomes on private land. These studies have ignored the effects of uncertainty of both bidders and administrators about factors such as landholder participation and the level of environmental benefits that will be delivered. This project will test whether distributing environmental ....Designing for uncertainty in conservation auctions. Economic theory and case study evidence show that tenders or auctions are more efficient than grant mechanisms for encouraging landholders to produce environmental outcomes on private land. These studies have ignored the effects of uncertainty of both bidders and administrators about factors such as landholder participation and the level of environmental benefits that will be delivered. This project will test whether distributing environmental funds via tenders is still efficient when uncertainty about various important factors is considered. Results from this research are expected to inform the cost effective design of systems to pay landholders for the provision of environmental benefits even when there is high uncertainty.Read moreRead less
Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources.

This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.Read moreRead less
