A small number of cane toads from South America were introduced into Northern Australia as an “eco-friendly” way to eradicate the menace of cane beetles which were destroying agricultural crops. The beetles were eradicated, the crops saved and the eco-system left with the cane toads to contend with ! In 70 years the toads had multiplied out of control with estimates running into millions, occupying half a million square kilometre of land, having a devastating impact on wildlife and even threatening some species to extinction. This even triggered a special scientific workshop in June 2006 at Brisbane to address the potential damage to eco-system ! The cane toad had attained the status of being listed as the “most significant pest” in Northern Australia ! Predicting and mitigating rapid changes in a eco-system has become a significant scientific challenge in recent times in order to understand dynamics of eco-systems at local and global scale influenced by human (eg. over fishing) and environmental factors. Computational ecology provides a computational approach to the modelling and analysis of large scale systems. The aim of this research is to focus specifically on computational methods for modelling and analysing “food webs” --- ecological networks of species in order to understand the “stability” criteria of such networks by finding the equilibrium solutions to non-linear differential equations. For instance some models predict that long food chains cannot be stable or that complex webs may be unstable. Understanding existing models should provide insight into the dynamics of networks when other factors are taken into account. Several existing tools uch as Gecko from Yale University and other tools being developed at Microsoft research labs will be studied to make a comparative study of the effectiveness of the underlying methods. The proposed research study will be carried out under the supervision of the principal investigator.
