Leanne’s current research focuses on monitoring and assessing fish species (teleosts and elasmobranchs) that comprise tropical marine ecosystems, with a particular interest in fishery species. She works on a number of ecological projects, assessing the diversity and abundance of fishes in relation to their environment, location and disturbance, and understanding drivers of presence, movement and biology of marine individuals.

Leanne has a background in biology and spatial ecology of exploited fishes, with roles on projects investigating species-habitat associations, movement ecology, life histories (ageing and reproductive biology) of tropical reef and inshore fishes, and identifying and monitoring catch composition of commercial and recreational fisheries. Leanne’s PhD investigated a combination of innovative methods to better understand movement patterns of important fishes at multiple scales, and in relation to environmental conditions. With experience from these diverse projects at AIMS, JCU and Fisheries, Leanne aims to fill ecological and biological knowledge gaps that will assist in the sustainable management of marine species and their environments.

Leanne’s current research focuses on understanding the drivers of species richness, relative abundance and community composition for a number of projects, primarily using Baited Underwater Video Stations (BRUVS). Leanne’s research investigates the influences of spatial, habitat and environmental variables, industry activity, coral bleaching, fishing pressure and through time, to better characterize fishes in tropical locations. These projects with Industry partners, rangers and the Global FinPrint Project has incorporated submerged reefs, emergent reefs and islands in WA, NT, Qld and across the Pacific Ocean.
