Lamarckian lizards: novel integration of telomere epigenetics, free radicals and innate antioxidants in condition-dependant sexual signal evolution. In 2009, the Nobel Prize in physiology was awarded Drs. Blackburn, Greider and Szostak for discoveries on telomeres. This project will investigate how telomeres not only cap chromosomes from destruction by free radicals, but also have a key role in life itself, in their influence on ageing, longevity, ornaments and lifetime reproductive success.
Maternal effects and sex allocation: an integrated approach. This project will produce research of a high international standard combining a number of key fields in evolution and ecology. The team we have assembled provides a link between Australian-based researchers and leading overseas theoreticians facilitating integration between evolutionary theory and empirical research on the unique Australian fauna. Furthermore, while climate change is identified as a priority area for research, Australi ....Maternal effects and sex allocation: an integrated approach. This project will produce research of a high international standard combining a number of key fields in evolution and ecology. The team we have assembled provides a link between Australian-based researchers and leading overseas theoreticians facilitating integration between evolutionary theory and empirical research on the unique Australian fauna. Furthermore, while climate change is identified as a priority area for research, Australia typically lacks the history of long-term phenological monitoring that is required to understand climate change impacts. This project takes an important step towards addressing this shortcoming.Read moreRead less
Molecular aggression: variation and heritability of the levels of reactive oxygen species, and their effects on the evolution of life histories in the wild. Three areas of biology have intrigued every generation since Aristotle (c. 300 BC)- sex, embryology, and ageing. This proposal targets all three of these areas with a special focus on aspects of ageing. In particular, we assess how 'free radicals', so often identified in our food and wine for good and bad, exert selection on living organisms ....Molecular aggression: variation and heritability of the levels of reactive oxygen species, and their effects on the evolution of life histories in the wild. Three areas of biology have intrigued every generation since Aristotle (c. 300 BC)- sex, embryology, and ageing. This proposal targets all three of these areas with a special focus on aspects of ageing. In particular, we assess how 'free radicals', so often identified in our food and wine for good and bad, exert selection on living organisms and whether resistance (and defense) towards free radicals may drive evolution of ageing in the wild, its trade offs with fertility and fecundity, and how it is influenced by sexual or non-sexual reproduction. In spite of excellent work in the laboratory, this is the first attempt to do this in 'the real world' and will extend Australia's excellent reputation in evolutionary biology.Read moreRead less
