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:
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 dinosaurs and many other species which definitely seems to confirm their robustness. Their anatomy and physiology is very different from that of marine bony fish, and clearly well suited for survival in the marine environment. But are they really equipped to deal with the current pace of environmental changes? Temperature changes, eutrophication, hypoxic zones and pollution act in concert in coastal zones. Our research touches on the effects of some of these parameters, and emphasizes that special attention needs to be paid to the unique physiology of these fish. A suitable suite of biomarkers, different from those for teleosts, needs to be developed to support efficient conservation measures.

Gudrun De Boeck studied biology at the Universities of Hasselt (BSc) and Leuven (MSc) in Belgium. After a short period in the private sector (aquarium fish trade), she got immersed in the field of fish physiology and ecotoxicology and obtained her PhD at the University of Antwerp on the effects of copper on common carp in 1996. During het postdoctoral period, at McMaster University (Canada) and the University of Antwerp, she worked with different marine and freshwater species and became interested in comparative studies within and between species. The underlying physiological mechanisms that make one species more sensitive to environmental changes are a fascinating field of research, and at the core of her research. Since her appointment as assistant professor at the University of Antwerp in 2006, she now became the group leader of the new research group ECOSPHERE, which combines expertise in fundamental and applied research in aquatic ecology and in aquatic and terrestrial ecotoxicology and ecophysiology. Our research group aims to underpin environmental management decisions with fundamental knowledge at different levels of organisation, from cell to ecosystem.

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: 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: 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
