KEY THEMES
Impact predictions for invasion and biocontrol sciences
Predicting the ecological impacts of invasive species and biological control agents has remained a fundamental challenge in ecology. I am examining the utility of classic ecological concepts in impact quantifications for the invasion and biocontrol sciences. Novel metrics which enable context-dependencies, such as climatic change, to be explicitly integrated into impact predictions are being developed.
Economic costs of biological invasions
Impacts of biological invasions on socioeconomic enterprises have lacked examination at multiple scales, negating adequate investments by managers in prevention or control measures. My research is quantifying, describing and predicting the effects of current and future species invasions on economies using the InvaCost database. The economic costs of invasions for specific national economies, taxonomic groups, sectors and habitat types are being compiled.
Ephemeral wetland ecology
Ephemeral wetland ecosystems remain poorly understood despite their importance for aquatic biodiversity, and are under high risk of degradation in arid regions due to human activities and changing climate. My research is developing improved understandings of how ongoing environmental change alters the structuring and functioning of these highly dynamic ecosystems, aiding future predictions.
Biosecurity to prevent invasions
The development of spread prevention measures is imperative for mitigating ecologically- and economically-damaging species introductions. I am developing novel, practical and cost-effective approaches to treat human-mediated vectors and reduce the translocation of invaders between highly vulnerable aquatic systems.
Microplastics in aquatic food webs
Microplastic pollution is widespread across all regions and habitat types globally, with often unknown ecological ramifications. My research examines the impacts of microplastic pollution on aquatic foodwebs and is identifying novel biological pathways for microplastics to disperse and accrue among habitat types. Further, novel methods to quantify microplastic uptake are being developed.
