Understanding biodiversity by experimental analysis of links between physical, chemical and biological properties of intertidal sediments. The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats.

The coastal zone accounts for 38 % of total environmental services, estimated as $12 trillion per year. Over 90 % of current development and 80 % of Australians are found within 50 km of the coast, putting enormous pressure on these habitats. Intertidal/shallow subtidal sediments are the most extensive and productive (biologically and economically) coastal habitats, supporting much of Australia's unique biodiversity. Their functioning depends on complex interactions among physical, chemical and biotic processes, yet is largely unknown. Understanding these processes is crucial for coastal planning and management, to minimise habitat-loss and retain biodiversity in these important habitats.Read moreRead less
Do pollution events facilitate biotic invasion in marine systems? This project aims to determine whether pollution affects the biological resistance of assemblages to invasion. The discharge of toxicants into coastal waters is an increasingly important source of disturbance that has the potential to make marine assemblages more susceptible to biotic invasion. The project will determine if pollution events facilitate the colonisation, persistence and spread of non-native species and how initial a ....Do pollution events facilitate biotic invasion in marine systems? This project aims to determine whether pollution affects the biological resistance of assemblages to invasion. The discharge of toxicants into coastal waters is an increasingly important source of disturbance that has the potential to make marine assemblages more susceptible to biotic invasion. The project will determine if pollution events facilitate the colonisation, persistence and spread of non-native species and how initial assemblage diversity modifies this response. The generality of several important ecological hypotheses developed in plant communities are tested in marine systems for the first time and extended to include the role of toxic disturbances.Read moreRead less
