DNA reveals the past and future of coral reefs
New DNA techniques are being used to understand how coral reacted to the end of the last ice age in order to better predict how they will cope with current changes to the climate. James Cook Univer
From 2005 to 2022, the main node of the ARC Centre of Excellence for Coral Reef Studies was headquartered at James Cook University in Townsville, Queensland (Australia)
Stephen obtained his B.Sc in marine biology and biotechnology from McGill University in Montreal, Canada, an Advanced Technical Diploma in Geographic Information Systems from the British Columbia Institute of Technology, and a Master’s degree in Zoology from the University of British Columbia, where his research focused on terrestrial and oceanographic predictors of Steller sea lion habitat in the north Pacific. He has worked with the Vancouver Aquarium Marine Science Centre and the Vancouver Museum, and spent several years in the private sector as a wildlife biologist with an environmental consulting firm. His current research interest centres on spatial ecological modeling and impacts of climate change.
Climate change poses a dual threat to coral reefs in the form of increased ocean temperatures and ocean acidification. However, the future state and health of reef ecosystems depends not only on climate change scenarios, but also on the trajectory of existing natural and anthropogenic stressors at a local scale. My thesis aims to identify the types of stressors that are most likely to influence the condition of the Great Barrier Reef, and how these stressors interact to mitigate or enhance each other. Furthermore, I plan to construct models that will describe how ecosystem structure may change in the face of multiple stressors, and compare these models against existing models of coral bleaching and disease to determine whether they offer novel insights or enhanced predictive ability of these events. Finally, I plan to examine how effective different local management strategies may be in mitigating the effects of global climate change.

A new study on the effects of climate change in five tropical countries has found fisheries are in more trouble than agriculture, and poor people are in the most danger. Distinguished Profess
James Cook University researchers have found brightly coloured fish are becoming increasingly rare as coral declines, with the phenomenon likely to get worse in the future. Christopher Hemingson, a
Researchers working with stakeholders in the Great Barrier Reef region have come up with ideas on how groups responsible for looking after the reef can operate more effectively when the next bleaching
Abstract: As marine species adapt to climate change, their heat tolerance will likely be under strong selection. Individual variation in heat tolerance and its heritability underpin the potential fo
Abstract: The Reef Ecology Lab in KAUST’s Red Sea Research Center explores many aspects of movement ecology of marine organisms, ranging from adult migrations to intergenerational larval dispersal
Abstract: Macroalgal meadows are a prominent, yet often maligned component of the tropical seascape. Our work at Ningaloo reef in WA demonstrate that canopy forming macroalgae provide habitat for ad
Abstract: Sharks are generally perceived as strong and fearsome animals. With fossils dating back at least 420 million years, sharks are not only majestic top predators but they also outlived dinosa
Abstract: Connectivity plays a vital role in many ecosystems through its effects on fundamental ecological and evolutionary processes. Its consequences for populations and metapopulations have been
Abstract: Evolution of many eukaryotic organisms is affected by interactions with microbes. Microbial symbioses can ultimately reflect host’s diet, habitat range, and even body shape. However, how
Abstract: The past few years have seen unprecedented coral bleaching and mortality on the Great Barrier Reef (GBR) but the consequences of this on biodiversity are not yet known. This talk will expl
