I am a professor in marine ecology working in temperate, subtropical, and tropical coastal ecosystems, with a special focus on fishes. Over the past three decades, 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 this work in the Caribbean, Eastern Africa, and Australia. I held a Future Fellowship awarded by the Australian Research Council to study the effects of climate change on fishes and marine ecosystems, and I have continued this field of research until present day. Most of my climate change research is performed in Australia, New Caledonia, Japan, and New Zealand, with a particular emphasis on climate change adaptation and ecosystem resilience. 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 fishes, how this will alter their interactions with their environment and other species, how this then modifies population dynamics and species communities, and what the implications are for the fisheries, biodiversity, functioning, and resilience of marine ecosystems in the near future. My research includes approaches and techniques such as aquarium studies, large mesocosms, natural analogues of climate change (CO2 vents and warming hotspots in Australia, New Caledonia, New Zealand, and Japan), quantitative modelling, meta-analyses, and stable isotope (foodweb) analyses.
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 in (South) Australia and Cocos Islands.
Student projects
I have a wide range of projects available for Ph.D., Honours, and Master's students with an interest in marine ecology, with research locations in South Australia, interstate (New South Whales and Queensland), and internationally (New Caledonia, Japan and New Zealand). My main foci are on: 1) climate change effects on fishes and marine ecosystems, and 2) coastal ecosystem connectivity for fishes. I also study 3) the vulnerability of our iconic leafy seadragon to climate change, and 4) the effects of harmful algal blooms on marine ecosystems and fish populations. 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 cells, 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.

Climate Change
Multiple projects are available to study climate change effects (e.g. ocean warming, ocean acidification, marine heatwaves, 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. Projects focus on the physiology (e.g. growth, metabolism, otoliths, oxidative stress), 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 mesocosms and natural laboratories (ocean warming hotspots and volcanic CO2 vents). 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 recognised 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.
Save our leafy seadragons
Leafy seadragons (Phycodurus eques) are a species of seahorse that are endemic to the temperate southern waters of Australia. This species of seadragon is the marine emblem of South Australia! Its majestic shape and colours attract large numbers of scuba divers from all over the world. The largest number of sightings are from a single region, i.e. the Gulf St. Vincent (South Australia). Although the leafy seadragon is widely known by the public, we hardly know anything about their behaviour and ecology. Unfortunately their populations are declining, possibly due to climate-driven loss of their preferred kelp habitat. Research projects to study the behaviour and ecology of the leafy seadragon are available, as well as assessing the impacts of the recent Harmful Algal Bloom in South Australia on their populations.
Effects of mass seagrass loss on marine communities in the Cocos (Keeling) Islands)
Australia’s Cocos Keeling Islands comprise an oceanic coral atoll that supports a unique marine biodiversity due to their remote location and low human impact. The 120-acre lagoon is the main habitat for many coastal marine species, as the Islands are surrounded by deep oceanic waters. The lagoon is a key nursery and foraging area for many species, supporting local fisheries, marine biodiversity, and various endangered and threatened species. The lagoon has recently lost > 95% of its seagrass beds due to human impacts, sea turtle overgrazing, and climate change. Projects are available to study the effects of the seagrass and coral loss in the lagoon on fisheries species and marine biodiversity, and investigate potential solutions to restore habitats. This project is done in collaboration with the local Marine Park.
