I am a professor in marine ecology working in temperate and tropical coastal ecosystems, with a special focus on fishes. Over the past decade, I have examined how ecosystem connectivity affects the functioning and resilience of tropical coastal ecosystems including coral reefs, seagrasses, and mangroves. I have done most of my work in the Caribbean, Eastern Africa, and Australia. I recently held a Future Fellowship awarded by the Australian Research Council to study the effects of climate change on fishes and marine ecosystems. My work contributes directly to today's environmental issues by providing answers to contemporary scientific questions as well as management and conservation related problems.

Climate change

Climate change stressors such as warming and acidification of the oceans are predicted to have dramatic impacts on the diversity, abundance, and distribution of fish species worldwide. We are only beginning to understand how these two stressors interactively affect the physiology and behaviour of fishes during different stages of their life cycle. The degree to which fishes adapt to or tolerate changing conditions will determine their persistence in their original habitats as well as their ability to extend their ranges to novel habitats or higher latitudes. My current research focuses on providing an understanding of how climate change stressors will affect the behaviour and physiology of fish species, how this could modify population dynamics and species community structuring, and what the implications are for the biodiversity, functioning, and resilience of marine ecosystems in the near future. A 3-year grant from the Australian Research Council currently allows me to focus in detail on studying the impacts of range extending tropical fish species on temperate marine ecosystems in Australia.

Connectivity

Ecological connectivity plays a key role in the functioning and resilience of coastal ecosystems. Habitats such as such as seagrass beds, mangroves, and coral reefs are a ubiquitous feature of many clear-water tropical coastlines. Their juxtaposition within the coastal seascape often leads to an enhancement of fish diversity and abundance along their boundaries. I am specifically interested in the way in which fish movements connect neighbouring ecosystems and affect the functioning of recipient systems. Studying the nursery function of vegetated habitats for juveniles of coral reef fishes has formed a core area of my research. I have used techniques such as tagging, telemetry, and stable isotope analysis of fish otoliths and tissues to track fish movement and dispersal. In my current studies, I use this knowledge to answer questions about the effects of ecosystem connectivity on marine reserve functioning, population dynamics of reef fishes, and resilience of reefs.

Student projects

I have a wide range of projects available for Ph.D., Honours, and M.Sc. students with an interest in marine ecology. My main foci are on 1) climate change and marine ecosystems, and 2) ecosystem connectivity, but other projects are also open for discussion. My research is largely experimental, based on field, mesocosm, as well as laboratory work, and focusing on processes that operate at the levels of individuals, populations, communities, and ecosystems. I also have a keen interest in meta-analyses to answer contemporary macro-ecological questions. See some examples of potential student projects under 'Teaching'. I work together with a range of renowned experts in the field, providing students with a broad mentoring experience.

Potential student projects

Climate Change

Multiple projects are available to study climate change effects (e.g. ocean warming, ocean acidification, extreme weather events) on marine animals and ecosystems. While the focus is largely on fishes, research includes the ecological interactions with other vertebrate and invertebrate species as well as interactions with their aquatic habitats. Advanced field as well as lab experiments are done on a variety of ecologically or economically important species (e.g. barramundi, snapper, mulloway, Port Jackson sharks). Projects focus on the physiology (e.g. growth, metabolism), behaviour (e.g. predator-prey interactions, feeding behaviour) and the ecology (e.g. habitat use, competition, invasive species, trophic cascades) of marine organisms. Complex experiments on community structuring and ecosystem functioning are done in our state-of-the-art mesocosm facility at SARDI West Beach. The overall focus of my research is to understand and better predict the long-term impacts of global change on marine species and functioning of coastal ecosystems. This research theme has received much international and local media attention, has a multi-disciplinary approach, and includes field-work components.

Sensory ecology and fish behaviour

The majority of marine species have a two-phase life cycle, one of which is an oceanic larval phase. Larvae possess excellent navigational capabilities and can have a large influence on where they end up after settlement. Several projects are available that investigate the attraction of larval fish species towards olfactory and sound cues from coastal habitats (e.g. rocky reefs, mangroves, seagrass beds, kelp). Projects also focus on how human deterioration of coastal habitats may affect settlement behaviour of marine larvae, including the effect of anthropogenic sound on hearing and the effect of coastal water quality on olfaction by fish and invertebrate larvae.

Nursery function of coastal ecosystems

Mangrove and seagrass ecosystems have long been recognized for their nursery role for a variety of coastal fish and crustacean species. Many of these species are of commercial importance or perform important ecological roles. Projects are available to study the underlying mechanisms of nursery habitat use (i.e. based on experiments), or understand how coastal ecosystems and estuaries locally enhance juvenile abundances/diversity of fisheries species (i.e. based on patterns revealed from field work) and how this depends on different levels of protection (e.g. sanctuary type) systems.
