Abstract
During the 2024 global mass bleaching event, a rapid bleaching assessment was conducted on two large benthic foraminifera populations on One Tree Reef, southern Great Barrier Reef. In tropical reef ecosystems, large benthic foraminifera are major carbonate sediment producers and function as important ecological engineers. We documented the thermal stress of Marginopora vertebralis and Baculogypsina sphaerulata from two high-density populations along the leeward and windward side of One Tree Reef in March 2024 following an 8-degree heating week with local on-reef temperatures exceeding 30 °C. Bleaching was more prevalent at the lower-energy leeward site (81.4% of M. vertebralis and 80.2% of B. sphaerulata individuals bleached, respectively) than the windward site (31.1% of M. vertebralis and 40.8% of B. sphaerulata bleached), suggesting localised hydrodynamic exposure has a significant impact on the health and bleaching susceptibility of benthic foraminifera. This study provides a rapid bleaching guide and emphasises the necessity of ongoing monitoring of benthic foraminifera to understand local and regional impacts of climate-induced stressors on reef carbonate production.
