Research Interests
My overall interest is in marine benthic community ecology, with two distinct directions:
- To identify the mechanisms that underpin the dynamics of coral and temperate reef systems, including effects of introduced species and anthropogenic impacts such as effects of fishing. The approach is quantitative and involves in situ experimental and descriptive work.
-
Theoretical aspects of spatial dynamics of communities. It is largely based on simulation modelling, and addresses spatial self-organising, how spatial structure influences community dynamics and the evolution of species in communities, and identifying characteristic scales of marine systems.
Software for Ecological Research - Downloads COMPETE (2002)
COMPETE is an individual-based spatial modelling software package to simulate ecological interactions and evolution in sessile and modular organisms competing for space. 
Estimating Characteristic Length Scales (CLSs) of ecological systems (2006)
This software package enables estimating CLSs from spatially resolved data (maps) of the distribution of species or habitats (see Habeeb et al. 2005 ). The CLSs define the optimum scales to observe the deterministic trends of a system.
