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:
The Earth’s climate is changing rapidly mostly due to anthropogenic disturbances. The average temperature of the ocean is projected to increase up to 3°C by the end of the century, and the oceans are progressively becoming more and more acidic. This will pose a serious threat to the survival of many aquatic species. To persist, populations will either need to shift their geographic distributions or adapt through genetic evolution or phenotypic plasticity.
It is unclear if and how marine species, such as tropical fishes, will adapt to these rapid changes in ocean temperature and acidity. Although many organisms are susceptible to future climate changes, some species shows remarkable ability of acclimation after generations. In my talk I will discuss our latest research that by mean of an integrative genomics analysis, identified molecular pathways responsible for transgenerational acclimation of reef fish to climate stressors and shown that selective genomic-wide DNA methylation serves as a central epigenetic mechanism mediating transgenerational acclimation to climate change.

Tim graduated from the University of Milan in Italy and now is a Full Professor of Marine Genomics at King Abdullah University of Sciences and Technology (KAUST), Adjunct Professor of at the University of California in San Diego.
Tim has more than 140 peer-reviewed publications as well as four book chapters which have been cited more than 16,000 times.
He is has received the 2008 Dolph Adams prize for the most-cited article. Nature Biotechnology selected Tim’s work on biological machine learning classifiers as one of the 2010 top 10 major breakthroughs in Computational Biology
Tim’s research focus on the effects of the rapidly changing climate on coral reef fish populations. By mean of integrative genome and epigenome approaches Tim’s lab is questioning the adaptive abilities of coral reef fish to climate stressors such as ocean warming and ocean acidification

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
