Ian collected data for his PhD from the mangrove sites in Indonesia and developed a thesis on Niche creation for cryptofauna by teredinid bivalves in mangrove ecosystems. Extensive field surveys of the mangroves provided a comprehensive assessment of the forest structure and standing stock of large woody debris. Wood-boring animals and cryptic communities found living within the galleries made by the wood-borers were then identified. In-situ experiments using wooden panels provided rates of decay and wood consumption rates over temporal and spatial parameters. Laboratory work was undertaken to further expand the project. Ian was supervised by Dr Simon Cragg.
