Associate Professor Corey Bradshaw

Biography/ Background

I am Director of the Marine Programme at The Environment Institute and have a joint appointment with the South Australian Research and Development Institute. I am employed through Marine Innovation South Australia. I have a broad range of research interests including population dynamics, extinction theory, sustainable harvest, climate change impacts on biodiversity, invasive species, and work on a variety of taxa from the Antarctic to the tropics (see more detail below).

Research Interests

I have a diverse, multidisciplinary and innovative research portfolio which has and continues to include topics ranging from the dynamics of populations, predicting the vulnerability of species to environmental change, optimal foraging theory, sustainability harvest & density reduction, disease dynamics, vector ecology and environmental drivers of population change, including climate change biology. Specific research foci include analytical and computer simulation modelling, quantitative behavioural ecology, foraging dynamics, impacts of tropical habitat modification on biodiversity, wildlife population management and sustainable harvest, evaluation of the minimum viable population size concept, examining the relative contribution of intrinsic (density regulation) factors on population trajectories and the ecology of invasive species. See my short Curriculum Vitae.
