Researchers loading their boats on a recent morning in November
Early summer can be a spectacular, if not critical time, for coral reefs. We’re talking about the natural phenomenon of coral spawning, a spectacle of awe and wonder, described as an underwater snowstorm by those lucky enough to experience. If conditions are right, spawning typically occurs following the full moon in November. Coral polyps release eggs and sperm in synchronicity, and, if all goes to nature’s plan, form larvae which settle on the reef to begin forming new colonies and continue the coral life cycle. Needless to say, a process vital for reef recovery. Around Lizard this year, coral spawning was observed on November 8, 9 and 10. As November’s full moon fell early in the month, spawning was also observed on December 9, an occurrence known as split-spawning.
The summer months are also a busy reproductive time for reef fish and, ipso facto, for researchers at Lizard. Warmer waters and greater availability of food generally assist breeding conditions. It’s a good time for those researchers whose work focusses on studying corals and reef inhabiting fishes, and their interdependency. As usual for this time of year, we’re happy to relay that the Station is fully booked for the next few months.
Looking ahead, moderate to high levels of heat stress are predicted for the northern Great Barrier Reef again this summer (visit Coral Reef Watch site). However, it is too soon to know whether these predictions will eventuate as regional weather events are difficult to forecast.
This coming January will mark a year since “new” co-directors, Dr Emily Howells and Dr David Abrego, stepped into the demanding role of jointly running the Station. Many of our Foundation supporters met them both in Sydney or Melbourne at our October events and were impressed by their extensive experience and warmth. They write: “It’s hard to believe a year has almost gone by already. The joint Director roles are certainly amongst the most varied, interesting, and rewarding we’ve had in our careers. We care deeply for coral reefs and feel privileged to be able to facilitate world-class research and education on these stunning ecosystems with the support of the Australian Museum and the Lizard Island Reef Research Foundation.“
