My main research interest is the role of spatial and temporal heterogeneity in the structure and function of ecological systems. Under the guise of various different projects my laboratory works to, ultimately, establish the various ways in which variability determines how ecological systems work.
We focus on plant ecology, particularly in arid and semi-arid lands.
This is a collaborative project with Dr. Peter Chesson (U. Arizona) to test the validity of the storage effect model to explain the coexistence of species in the annual plant guild.
We have tested experimentally the effect of rainfall variability on the structure of annual plant communities, the role of the soil seed bank, the various germination responses to environmental conditions, and the importance of spatial distribution in determining the balance between intra and interspecific competition). Future work will include more detailed studies of patterns of species distributions, the mechanisms that determine these patterns, and the consequences for coexistence between species.

For the last few years we have investigated the ecological characteristics of plants that invade natural ecosystems in South Australia, with the participation of several students. The main areas of study are:
Potential use of a native parasitic plant (Cassytha pubescens) as biological control agent.
This project, funded by an ARC Linkage Grant) investigates the interactions between C. pubescens and native and invasive plants. We aims to assess the potential use of the parasite to control invasive plants such as Cytisus scoparius (broom) and Ulex europaeus (gorse). We also want to further understand the ecophysiological mechanisms of the interaction and the ecological implications. We use a combination of laboratory, glasshouse and field experiment.

This project investigates the effects of disturbances produced by mining related activities such as mineral exploration. The plant component of the study focuses on the differences in the plant community structure and dynamics between linear clearances used for mineral prospecting and adjacent undisturbed sites. Another aspect of the project includes the study of the requirements of native species for germination and establishment in areas used for mineral sand mining.
