The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentiall ....The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentially wide and novel significance. This project proposes to test the generality of our observations for other vertebrate-pollinated species, and to test the conservation and evolutionary consequences of reduced pollen dispersal caused by habitat fragmentation and declining pollinators for a pollination paradigm facilitating promiscuity.Read moreRead less
Dispersal and persistence of large-seeded forest species under global environmental change. This project investigates how decline of a key seed disperser, the emu, due to global environmental change (fragmentation, fire regime change, human population growth, climate change) affects the persistence and migration potential of endemic SW Australian forest plant species. Results will inform approaches to ecosystem management and conservation
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. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed ....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. 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
Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental param ....Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental parameter that influences the ability of a species to colonise new habitats. The project plans to characterise the functional links between specific mitochondrial DNA haplotypes, mitochondrial functions and organismal traits. The expected outcome is a more precise grasp of the processes influencing genetic variation within and among species, which would inform current issues in ecology and genetics.Read moreRead less
