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)
Aaron MacNeil is a quantitatively-oriented marine biologist working to understand the effects of disturbance on fish communities and the development of ecological benchmarks for marine resource management. Originally from Nova Scotia, Canada he has worked on fisheries and conservation management problems in a wide-range of ecosystems from French Polynesia to the Canadian Arctic. He holds a Master’s in Fisheries from the University of Georgia (USA) and a PhD in Marine Biology from Newcastle University (UK). Aaron is currently Research Scientist in Marine Biodiversity at the Australian Institute of Marine Science.
The dazzling complexity apparent to every visitor of coral reefs is both a source of wonder and difficulty for researchers studying the ecology of reef ecosystems. Unravelling this complexity requires a wide-range of analytical tools as well as the skill to use them appropriately. The main tool for inference in ecology is statistics, yet few biologists have a deep understanding of what statistics are and how they can be used effectively and creatively. In particular, studying the natural world through observation is a difficult task that is made still more difficult by the inadequate set of statistical tools taught at the majority of the world’s universities. Often researchers are given to using statistical recipes with the objective of passing a critical test of their idea and appearing to be empirical. However in many ecological studies – particularly those of high complexity and at large scales – no experiments are conducted and conventional recipes are both inappropriate and misleading. More importantly, this recipe-based approach to analysis stifles creativity and muffles ecological ideas. Breaking out of this analytical rut requires a refocusing of priorities, where ideas drive the analysis and statistics are the co-pilot.

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
