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)
Evidence is mounting for long-term effects of climate change on marine fish assemblages. Until now, much of this work has been conducted over short or intermittent time periods, or small geographical areas. I will present the emerging results of a macrospatial study of the entire UK marine fish assemblage measured annually for the last 30-years by commercially-independent trawls. There is clear support for the previously reported North Sea shift in community assemblage in the late-80s to early-90s, but also evidence of community change in NW Scotland, the Channel, and the Celtic and Irish Seas. Using newly developed analytical approaches we have explored these patterns at a fine spatio-temporal resolution, and examined relationships between measured community change and key environmental drivers. Through a series of hypothesis-driven investigations of these patterns, we have explored the species-level responses with respect to temperature and depth preferences, and life-history characteristics of each species. We hope to use these findings to draw out fundamental properties of ecosystem function, community response, and life-history vulnerability, and by extrapolating current trends we aim to produce ‘best guess’ predictions for the future of marine fish assemblages and fisheries.

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
