Research interests

Clive is a research scientist primarily interested in the population and behavioural ecology of large vertebrates and has focused his research on the demographic responses of wide-ranging marine animals to changes in climate. Clive has been especially interested in how marine predator populations respond demographically (changes in survival, fecundity and numbers) to changing climatic conditions by using natural variations in climate such as ENSO as proxies for broader climate change predictions.

Clive is currently investing the population dynamics of a common invasive bovid – the Asian swamp buffalo, in the Northern Territory. This works aims to provide managers and researchers with vital life-history information to mange the damage caused by buffalo in Northern Australia and to provide insights into effective management and density reduction to limit the possible spread of exotic diseases introduced into Australia.

A key issue when studying wild animals is the concern that people feel for the animals and the welfare of those research animals. Clive is leading a group assessing and defining the ethics of acceptable practise and the welfare of animals. This is a fertile and emerging area of study especially given that ecosystems and wild animal populations are under ever increasing pressures by humans and many require intensive and urgent study.
