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: Millions of people worldwide depend on coral reefs for their well-being. Governance for resilient coral reefs requires individuals to make inter-temporal trade-offs in the goods and services that they obtain from coral reefs. How people make decisions about future reef resource use is poorly understood, but may impact their ability to adapt to future socio-ecological change. Moreover, societal economic benefits from coral reefs are not well quantified, leading to potential distortions in trade-off analysis for different management systems. In this presentation I address these 2 issues by first quantifying economic benefits derived from coral reef fisheries at local and global scales. I then provide an empirical study on reef fishers’ discount rates, which measure one’s willingness to forgo current benefits in order to be able to enjoy higher benefits in the future. I use an experimental economics approach to elicit discount rates of small-scale reef fishers in Sabah (Malaysia) and Fiji, and then investigate under what socio-economic conditions low discounting behaviour may occur. This research improves our understanding of trade-offs that affect social, economic, and ecological outcomes of coral reef governance.
Biography: Louise completed her PhD in the RMES programme at UBC in 2011, which analyzed the time preferences of small-scale fishers in Sabah and Fiji. She finished her MSc in 2006 and worked as a research assistant with the Fisheries Economics Research Unit before beginning her PhD. Her past research involved assessing the status of the reef fisheries of Pulau Banggi, Sabah, from both an ecological and socio-economic perspective. She has also studied the socio-economic aspects of fisheries in Hong Kong and Fiji.

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
