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 association between the photosynthetic dinoflagellate Symbiodinium and corals has been known for many years. However, recent study has established that a number of other related alveolates are also intimately associated with corals including: the newly discovered chromerids (Chromera velia, Vitrella brassicaformis) and unidentified apicomplexans. Chromerids were isolated so far from corals in Australia, but the association of apicomplexans with corals was reported in the Caribbean and not yet on the Great Barrier Reef (GBR) of Australia. Moreover, the nature of the chromerids and apicomplexans associations with corals is unknown. This study aims to use ecological genomics and next-gen DNA sequencing tools to provide the baseline knowledge on the bio-geographic distribution of chromerids and apicomplexans on the Great Barrier Reef (GBR), their association with different coral hosts, and their role in coral health and disease. This study will also provide the analysis of the whole transcriptome response of the coral Acropora millepora following Chromera velia infection and measuring the differential gene expression profile.
Biography: Amin was born in Egypt where he completed his BSc in Zoology (excellent degree with honors) in 2006. He worked as a teaching assistant at Faculty of Science, Benha University, Egypt. As he developed a great interest in coral reef research, he did a Masters project on coral health and disease in the Egyptian Red Sea. This project provided baseline information on coral disease, coral bleaching, and other health issues that affect coral reefs in this region. Amin has been awarded a PhD scholarship from the Egyptian government. He is now a PhD student at David Miller’s lab, the ARC center of Excellence for coral reef studies, James Cook University. Amin’s PhD is supervised by Prof David Miller and Prof Bette Willis. His research focuses on studying the impact of newly discovered coral associated alveolates on coral health. Yet, the nature of these associations is unknown so it is unclear whether they have positive or negative impact on coral health.

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
