Our coral research investigates the molecular basis of reproductive timing in corals. The main study site is the Flower Garden Banks in the Gulf of Mexico. These two small, deep reefs (> 25 m deep and less than 40 acres) have over 70% coral cover and are in pristine condition. Over 90% of the individual corals are one of the five major Caribbean broadcast spawning species (Montastraea /Diploria), and all spawn on the same evening- usually eight nights after the August full moon. Timing at this site is extremely consistent, and each species spawning can be predicted to within approximately 10 minutes from year to year. We have been exploring how corals sense and respond to environmental cues to achieve this amazing accuracy. Using a combination of molecular analysis and field manipulation experiments we have identified molecular markers of light responsiveness and are using these to measure how corals sense solar and lunar illumination and use this information to regulate entrained and non-entrained elements of spawning behavior.
Scientists say outdated assumptions around gender continue to hinder effective and fair policymaking and action for climate mitigation and adaptation. Lead author of a new study, Dr Jacqueline Lau
For the first time, scientists have assessed how many corals there are in the Pacific Ocean—and evaluated their risk of extinction. While the answer to “how many coral species are there?” is
Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change. A new study shows plank
Scientists say stable seafood consumption amongst the world’s poorer coastal communities is linked to how local habitat characteristics influence fishing at different times of the year. In the co
Abstract: The vast majority of reef fishes have a life history consisting of a pelagic larval phase of typically 20 to 60 days, followed by larval settlement where they remain through their juvenile a
Abstract: Social networks have been and remain important across the Pacific Islands, and beyond, for building and maintaining social-ecological resilience. However, there is little quantitative infor
Abstract: The global conservation community is comprised of a range of organisations, processes, and professionals. Given the diversity of these actors, and the complexity of the systems that conser
Abstract: Seasons create a rhythm in nature and, by extension, in the lives of people who depend directly on natural resources. However, our understanding of how seasons affect the ways that people
Abstract: Oceanic shark populations have declined 77% over the past 60 years as a result of overexploitation in fisheries. However, sustainable shark management is limited to a few developed nations
Abstract: Vertigo3 is a new class of small, fast and agile ‘true-flight’ underwater glider, purposely designed for robotic, artificial intelligence-assisted broadscale marine surveys, and capable
Abstract: Recurrent marine heat waves are leading to widespread coral bleaching, transforming the structure and function of tropical coral reefs. Past bleaching events have highlighted large variatio
Abstract: Shallow-water tropical seascapes typically include a range of habitat types such as coral reefs, mangroves, macroalgal and seagrass beds. These habitats can occur in close proximity and are
