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)
On coral reefs, the biological and physical habitat provided by scleractinian corals is critical for coral reef fishes. Consequently, declines in the quality or quantity of coral habitat have had significant effects on the abundance and diversity of many reef associated fishes. Coral reef ecosystems around the world are very sensitive to changes in environmental conditions, particularly the effects brought on by global climate change leading to the bleaching and degradation of coral habitats. Coral bleaching also tends to have the greatest effect on branching coral species that support many coral-dwelling fishes.
My PhD aims to explore the importance of live coral for coral reef fishes, with a view to predicting the likely extent of fishes that may be affected by sustained and ongoing loss of corals due to global climate change. The focus of my PhD will be on corals as habitat, and thus fishes that typically occupy live corals. I aim to investigate what factors and processes (e.g. competition, predation, migration) cause declines in the abundance of coral reef fishes following extensive coral bleaching and coral loss.

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
