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)
Abstract: Climate change poses two main challenges for reef building corals: an increment in the frequency and severity of tropical storms; and ever increasing water temperatures. In contrast to the alarming rates of coral loss experienced worldwide, an increasing body of evidence shows that corals in fact have potential for adapting to these stressors. First, I will show that the diversity of life histories among scleractinians makes their assemblages resilient to cyclone damage through reconfiguration. I will highlight the importance of connectivity in the recovery process, and present a novel method to assess connectivity of coral populations. And second, I will discuss how the complex biology of the coral holobiont equips these keystone organisms with the potential for transgenerational acclimatization and adaptation to cope with predicted levels of ocean warming.
Bio: Greg Torda’s current research interest gravitates around the ecological, physiological and genetic bases of resilience of corals to stressors. He uses a variety of approaches, including state-of-the-art molecular techniques, controlled laboratory experiments, in situ field data collection and modelling to better understand the mechanisms that underpin the recovery of scleractinian populations from perturbations. Originally from Hungary, Greg received his MSc degree in Zoology from Szent Istvan University in 2000, and his PhD from James Cook University in 2013. For his PhD, Greg developed and applied a novel approach for describing ecological connectivity of corals by genetically assigning recruits to source populations. Since his PhD, Greg has been leading a research project that describes the recovery of corals around the Palm Islands following devastation from TC Yasi; and has been involved in teaching at the College of Marine and Environmental Sciences at James Cook University, in research at the Willis Lab and the Leggat Lab, and has led field expeditions for the Great Barrier Reef Foundation and Earthwatch.

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
