A fundamental concern in evolutionary biology lies in explaining the relationship between environmental variation and genetic processes and how this interplay can generate adaptation. Within this context, my research focuses on how selection shapes individuals to allocate limited resources to different life-history characteristics such as reproduction, growth and survival. Trade-offs between quantitative traits, between investment in reproduction and resistance to environmental stress, are particularly poorly understood in natural populations. This is mainly due to the fact that, despite research on the genetics of fitness traits, it is not well characterised how ecological variation influences these fitness trade-offs (and the way in which selection affects correlations between traits).
The study system I use to explore these questions is the rainforest fruit-fly Drosophila birchii, which have been collected from along independent temperature gradients in North-Eastern Australia.
