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)
Jennifer is a Postdoctoral Fellow at the Smithsonian Marine Station at Fort Pierce, in Florida (USA), where she is investigating the chemical ecology of fish foraging aggregations using the comparative study sites of the Smithsonian Marine Science Network in the United States, Belize and Panama. She received her bachelor’s degree in Wildlife and Fisheries Science from Texas A&M University and later went on to gain her PhD in Animal Behavior, from the University of California – Davis, under Dr. Gabrielle Nevitt. Her first postdoctoral position was as the Research Specialist for NOAA’s (National Oceanic and Atmospheric Administration) Flower Garden Banks National Marine Sanctuary, which presently oversees three coral reef-crested banks in the northwestern Gulf of Mexico. Having worked with NOAA’s Sanctuary Office and previously, with the National Marine Fisheries, her interests ultimately center on how basic science can inform better management practices, including marine reserve design.
Resident reef fish and pelagic reef-associated fish aggregate to forage and spawn over coral reefs. How these animals coordinate their aggregations is unclear, but one possibility is that they may recruit to a suite of natural chemicals released over coral reefs, especially during foraging events or through trophic cascade interactions. Presently, there is much we do not know about which chemicals and processes are important in fish chemical ecology. Fish use chemical cues to maneuver in their environment, yet we do not know how these cues vary in nutrient-enriched habitats, over healthy versus degraded reefs, or as plankton aggregations shift. Will the sensory capabilities of fish be able to adjust to these changing conditions? Understanding the mechanisms by which fish are locating productive areas is vital when planning for marine protected areas, determining essential fish habitat criteria, or predicting effects of a changing climate on the movement of fish. The central theme of my research is to understand how aggregation patterns of fish depend on the chemical signatures produced by transient foraging events, and how these signatures and corresponding behavioral effects vary across reef locations and across a range of organisms.

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: 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
