Plant-Insect Interactions and Climate Change Ecology Lab
1. Impacts of climate change on species and natural ecosystems
I am very interested in the potential impacts of climate change on species and ecosystems and am convinced that this is the most serious and challenging environmental issue we face. The main strength of my research in this area has been to integrate a number of different methods, from small-scale field and laboratory manipulations, to computer modeling of potential impacts on hundreds of species. This research interest has led to work focused on the implications of climate change on the applied issues of land management and conservation policy in Australia and elsewhere. I am currently involved in a large collaborative project assessing the impacts of climate change on the major environmental weeds in Australia.
2. Evolutionary ecology of plant-insect interactions
I have a long-standing interest in how plants and animals, especially insects, interact and how they have affected each other’s evolution. Herbivorous insects and green plants together make up over half of all known biodiversity. I find the range of behaviours shown by insects fascinating and believe that we are just beginning to unravel the complexity of their coevolution with plants. The potential for studying this topic in Australia is enormous as most insect ecology in Australia has been previously directed toward applied issues such as pest control, rather than fundamental ecology and evolution.
3. Spatial and evolutionary organization of biodiversity
I am working in collaboration with Profs Andy Beattie and Roger Kitching, leaders in the field of insect biodiversity, Dr Dan Faith, a leader in phylogenetic analysis for conservation purposes and with Dr David Nipperess to investigate the relationship between insect biodiversity and the phylogenetic relatedness of host plants. This project has the potential to make a major contribution to the global understanding of biodiversity and contribute significantly to conservation efforts.
I lead a dynamic and lively research group (known as PICCEL, the Plant-insect Interaction and Climate Change Ecology Lab). This group currently consists of six postgraduate students at Macquarie and two postdoctoral fellows. This group meets weekly to discuss recent journal articles and to offer feedback to each other on research projects.
I am unit convener for BIOL316 Invertebrates: Evolution, Behaviour and Diversity. I also give regular guest lectures for BIOL368 Ecology and Evolution and ENVE214 Climate Change.
