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: Changing sex is risky business, not least because the success of a given sexual strategy depends on the sexual strategies of others. Here, I summarise recent work on sex-changing hermaphroditic coral reef fishes, illustrating how individuals contend with uncertainty and assess the risks associated with alternative sexual strategy options. In doing so, I reveal a novel behavioural mechanism for cooperative sex allocation outcomes at the scale of local breeding groups that, in turn, has important implications for the ecology and evolution of sexual development, animal communication, and behavioural diversity.
Biography: Stefan has broad interests in ecology, evolution, and behaviour. In 2010 he received a PhD from JCU for his work on reef fish breeding systems and strategies, and is now working as a Postdoctoral Research Fellow at the ARC Coral Reef Centre. His current research focuses on collective-action and consensus-decision problems and the evolution of behavioural decision rules, animal communication, and strategic cooperation.

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
