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: I will start with a brief overview of the importance of movement as an element of ecological adaptation to environmental change. I will then consider two examples, both involving birds, of the challenge of embedding an understanding of movement ecology in research on ecological responses. The first example will present some early findings about birds that breed on Heron Island, on the Great Barrier Reef. The second will focus on some of the more interesting findings from my decade of field research on African ducks, including the first-ever translocation experiment on Egyptian Geese. Ah, you may say; but yes – Egyptian Geese are not true geese. Even though only about half this seminar deals specifically with coral reefs, it will explore a branch of ecology that you may find fascinating even if you are primarily motivated by things that go plop or bubble bubble bubble. Overall, I will attempt to demonstrate that even organisms that appear to be well adapted to living in variable environments may in fact be less capable of modifying their movement behaviours in response to unfamiliar circumstances than we would expect; thus, intensive research and deep knowledge of organismal biology are needed before we can confidently predict which animals will be winners and which will be losers under climate change.
Biography: Graeme Cumming is a professor at the ARC Centre of Excellence for Coral Reef Studies. He is originally from Zimbabwe and has lived in Townsville, with his wife and three children, since mid-2015. He runs a far-ranging and often interdisciplinary research program that focuses on understanding the relevance of spatial variation and system structure for the dynamics of complex systems.

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
