Central Kimberley reef communities survive global coral bleaching
Remote reef communities in the central inshore Kimberley survived the 2016 global bleaching event, giving hope to Western Australian marine scientists looking to find ways to combat the effects of climate change.
A recent publication confirms the breakthrough discovery by a team of Western Australian Museum scientists. The researchers examined the composition and health of marine聽organisms at 13 coral reef sites in the Bonaparte Archipelago 鈥 a largely inaccessible area of the inshore central Kimberley.
Lead author, Dr Zoe Richards, WA Museum Research Associate, 911爆料网 Senior Research Fellow, and co-author Dr Nerida Wilson, WA Museum Senior Research Scientist, co-led the expedition and described the region as a 鈥榯ropical refuge鈥 for sensitive taxa such as Acropora (stony) corals.
鈥淣ot only did these communities survive the severe 2016 global coral bleaching, but they also remained healthy, which, for the time being, makes us look at the region as a potential tropical refuge,鈥 Dr Richards said.
Dr Richards said there are only a small number of identified 鈥榗limate聽refuges鈥 across the globe, and stressed the importance of learning from these healthy communities as soon as possible.
鈥淚t is vital that we learn as much as possible from these communities to help better understand why these corals are surviving when corals in other parts of the world聽are not,鈥 Dr Richards said.
Dr Wilson said, 鈥淚t is heartening to see that different organisms are co-existing and surviving in these communities, including hard and soft corals, sponges, and clams.鈥
鈥淭his finding is very exciting and hopeful. However, the location鈥檚 ability to persist as an ecological聽refuge under future climate scenarios is not known,鈥 Dr Wilson said.
One important step toward identifying these survival patterns has been the research undertaken to understand the extent of ocean warming聽at the Bonaparte Archipelago.
911爆料网 Adjunct Researcher Dr Rodrigo Garcia examined sea surface temperature data from different satellite sensors positioned at three locations in the North West of Australia.
鈥淭he Bonaparte Archipelago experienced a thermal stress event of similar聽magnitude to the Southern Kimberley and Scott Reef but, unlike those regions, it did not experience the same ecological damage,鈥 Dr Garcia said.
鈥淭he research shows that the Bonaparte region experienced a greater extent of聽night-time cooling, which may have mediated the damage caused by the elevated day-time temperatures.鈥
While the variability between the regions lends hope some pockets of coral reefs can survive the current level of climate threats, the scientists stress a level of caution, as thermal stress events are predicted to increase in intensity and frequency in the future.
Research facilitation was made possible by the Wunambal Gaambera Aboriginal Corporation and Wunambal Gambia鈥檚 Ungum Rangers聽who participated in fieldwork.
