Australia: Sperm Bank Save Corals. Scientists want to prevent the extinction of some species…

SeaSim Coral Spawning Activities. Coral mass spawning is a natural phenomenon where corals of multiple species synchronise the release of sperm and eggs over several days following the full moon, which occurs only once or twice a year. The coral sperm and eggs float to the surface of the ocean and fertilise to form larvae which eventually settle on the reef to form new coral colonies. The spawning and larval phase of corals is a key event for the production of future coral generations and the replenishment of coral ecosystems. Further information on sexual reproduction in corals can be found here. On the Great Barrier Reef (GBR), coral spawning is an annual event which takes place in spring, usually after the October/November full moon. In contrast, the corals in Western Australia spawn during autumn. It is during this very narrow window of opportunity lasting only days that researchers can study how broad-cast spawning corals reproduce and collect samples of coral larvae for study.  The National Sea Simulator (SeaSim), an advanced experimental aquarium facility, has attracted international collaborators (e.g. from the Smithsonian Institute, University of Texas and the New York University – Abu Dhabi) to AIMS during this year’s GBR coral spawning event for a number of high profile projects to:Understand natural variation and the inheritance of temperature tolerance. Extend the GBR coral cryo-repository. Attempt to enhance coral resilience.Conduct experiments that examine the effects of dredging sediments, water quality and climate change on coral reproduction and their early life stages.  —–  Australia: Sperm Bank Save Corals.
