This NSERC discovery research program is based on the study of ecological complexity. We investigate the nature and origins of complex structures and dynamics in ecological systems through the application of theories and methods from the study of complex systems and the development of novel quantitative approaches in ecological informatics. By studying ecosystems as complex systems, the long-term goal is to advance scientific understanding of the structure and dynamics of natural systems so that we can more effectively manage human-environmental interactions. The current focus of our research activities is the modelling and characterisation of ecological complexity in terrestrial systems. Our short-term objectives address two key challenges in the field: 1) characterising complex structures and dynamics in ecological systems over multiple spatial and temporal scales, and, 2) understanding the mechanisms responsible for the appearance of these structures and dynamics (i.e., searching for relationships between pattern and process) through modelling. Over the next 5 years, we plan to address these challenges by: 1) developing new measures of spatial, temporal and spatiotemporal complexity that can be applied to ecological data, and 2) developing and using individual-based and other "bottom-up" models of ecosystems to explore the relationships between processes at different scales (e.g., gene, individual, community, landscape). Through this research program, we aim to develop better ecological indicators and more appropriate methods of ecosystem management, restoration and protection.
