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: There is often a mismatch between the scales at which ecosystems are threatened by human impacts and those at which management and policy are implemented. Better understanding the scales over which human impacts interact with ecological complexity is needed to develop more effective and strategic management of social-ecological systems. My research addresses this fundamental challenge by integrating data from multiple sources, such as remotely sensed and in situ data, and developing statistical models that consider variation across and within scales. In particular, I study how climate driven marine heatwaves, which are causing increasingly severe and widespread coral mortality, interact with local impacts, such as pollution and fishing. I will discuss how local and global human impacts have influenced patterns of coral bleaching and coral cover from studies globally, regionally, and at local scales. I will also address how interacting drivers that occur at multiple scales can be considered in local management decisions by identifying the bounds within which local management can be successful.
Biography: Dr. Mary Donovan is an incoming Assistant Professor at the Center for Global Discovery and Conservation Science and the School for Geographical Sciences and Urban Planning at Arizona State University. Prior to joining ASU, she was a Postdoctoral Scholar at the University of California Santa Barbara, and the Hawai‘i Institute of Marine Biology, and completed her PhD at the University of Hawai‘i at Manoa. Mary is a quantitative spatial ecologist focused on applied questions that inform conservation and management of coupled human-natural systems. She studies coral reef status and trends by applying quantitative spatial science alongside practitioners and stakeholders who are implementing management and policy. Her research includes studies on complex ecological dynamics, local and global impacts on reefs, marine spatial planning, invasive species, fisheries, and ecological resilience.

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
