| contents | Seagrass influence on mitigating ocean acidification and warming impacts on tropical calcifying macroalgae. Awaluddin, Khaerul Mayfield, Anderson B Tew, Kwee Siong Liu, Pi-Jen Seaweed Seawater Hydrogen-Ion Concentration Global Warming Ecosystem Temperature Tropical Climate Ocean Acidification Ocean acidification (OA) and warming pose significant threats to marine ecosystems, particularly by reducing calcium carbonate availability for marine calcifiers. Given that seagrasses can capture and store excess carbon, this study aimed to investigate whether seagrasses can mitigate the impacts of OA and elevated temperatures on three calcifying macroalgae: Mastophora rosea, Halimeda opuntia, and Mesophyllum sp. A 12-week mesocosm experiment was conducted, where the algae were cultured with and without seagrass under gradually increasing stress conditions: ambient conditions, OA alone for four weeks, OA combined with elevated (but non-stressful) temperatures (28 °C) for four weeks, and OA plus a stress-inducing temperature (31 °C) for two weeks. Results indicated that OA and warming negatively affected M. rosea, while H. opuntia was more strongly impacted by temperature alone. Mesophyllum sp. Exhibited resilience to both OA and elevated temperatures. Contrary to expectations, the presence of seagrass did not mitigate the negative effects of OA and warming on these calcifying macroalgae species. |
