PLOS Clim 2(4):Įditor: Rui Rosa, MARE - Faculdade de Ciencias da Universidade de Lisboa, PORTUGAL The 2019 marine heatwave suggests an uncertain future for high-latitude ecosystems. Given the isolation of high-latitude reefs such as Lord Howe Island, our results highlight the importance of understanding the impacts of bleaching, mortality and bleaching recovery on coral population structure and resilience of high-latitude coral reefs.Ĭitation: Moriarty T, Leggat W, Heron SF, Steinberg R, Ainsworth TD (2023) Bleaching, mortality and lengthy recovery on the coral reefs of Lord Howe Island. and minimal bleaching and no mortality in Isopora cuneata during the study period, typically highly susceptible species. Importantly, we found no evidence for bleaching or mortality in the Acropora spp. However, there was a significant increase in the abundance of healthy coral colonies at the inshore site, suggesting the recovery of the surviving bleached corals at this site. Interestingly, during the eight-months following bleaching, there was no evidence of bleaching recovery (i.e., re-establishment of symbiosis) at the offshore lagoonal site. and Seriatopora hystrix, were the most susceptible to bleaching, with all coral colonies found either bleached or dead at the most affected inshore site during and following peak heat stress. The four most dominant species, Stylophora pistillata, Pocillopora damicornis, Porites spp. Coral mortality of up to 40% was recorded in the reef’s most severely impacted near-shore area. Significant differences in bleaching prevalence were observed across the lagoonal coral reef, ranging from 16 to 83% across offshore and inshore reef regions and with variable onset timing. Here we document the extent of coral impacts within the Lord Howe Island lagoonal reef and the recovery from bleaching eight-months later. Coral bleaching and mortality were observed at the southernmost coral reef, Lord Howe Island Marine Park, during the summer of 2019, coinciding with anomalously high sea surface temperatures across the reef system from January-April. Water temperatures beyond the corals optimum threshold causeing coral bleaching and mass mortality, impacting our global coral reef ecosystems, including marginal high-latitude reefs. ![]() If you’d like to see more from Intelligence Fusion, you can follow us on Twitter too.Oceanic thermal anomalies are increasing in both frequency and strength, causing detrimental impacts to coral reef communities. This ensures that all of our data is as accurate as possible and clients can act on the information we send without having to waste their own time and resource fact-checking every alert. Luckily, our team are trained to use various tools and techniques to help verify information from open sources, including various intelligence processes to validate media and reports as well as a standard military method of grading sources by credibility and reliability. Fake news is a growing phenomenon and is becoming more and more difficult to identify. Aside from the hundreds of news accounts on Twitter that we track, Intelligence Fusion’s analysts are often alerted to a developing incident in its early stages by regular Twitter users who may be a witness to the situation.īut just because it’s on social media, doesn’t always mean it’s true. And it’s not just legitimate world news Twitter accounts, news agencies or journalists that are the first to break the news. The wide range of Twitter news accounts mean that the Twittersphere is an excellent place to stay in the know when it comes to global affairs. ![]()
