Beschreibung: Experts release a roadmap for harnessing the potential of assisted evolution to help save corals. The IPCC predicts that if warming reaches 2°C, 99% of all coral reefs will be lost in less than 30 years. It is clear that to ensure the future of corals, the highest priority must be reducing global greenhouse gas emissions. However, even with swift and substantial reductions in emissions, corals will continue to face increasing temperatures for the foreseeable future, which can result in extensive coral mortality and local extinction of some coral species. While recent studies have shown that corals may exhibit some degree of adaptation to ocean warming, it is unclear whether corals are able to survive the rate of temperature change during heat waves that will become more frequent under several climate change scenarios. If corals lack what it takes to naturally rapidly adapt to new environmental regimes, they may fail to survive a warming ocean. This is where assisted evolution could be a game-changer. Growing our understanding of the power of adaptation In January 2023, we held a workshop on assisted evolution co-organized with the Australian Institute of Marine Sciences (AIMS) as part of CORDAP’s Scoping Studies (a series of planning sessions and technology roadmap studies to shape our funding priorities). Our aim was to develop a visionary roadmap, offering recommendations on how to prioritise assisted evolution in R&D investment in the future. Assisted evolution is the use of human interventions to speed up the natural evolutionary process. It may allow coral species to adapt faster than they would if left unaided, allowing reefs and corals to keep better pace with the ocean’s environmental changes. The first step in creating this strategy was to pinpoint where we are now in our understanding regarding the potential and impacts of assisted evolution on enhancing coral tolerance to stress conditions like ocean warming. Our experts unanimously agreed that assisted evolution methods cannot be understood and ...
