- Retention of increased maximum oxyregulation capacity in corals transplanted from an extreme mangrove environment to a reef flat. Dilernia, Nicole J Suggett, David J Roper, Christine D Alderdice, Rachel Voolstra, Christian R Kühl, Michael Camp, Emma F Animals Anthozoa Coral Reefs Oxygen Wetlands Ecosystem Loss of oxygen (O) from the world's oceans to physiologically-critical levels ("hypoxia") is an important, yet understudied stressor for coral reefs. However, extreme reef-neighbouring ecosystems such as mangrove lagoons that are routinely subjected to frequent low-pO exposure (i.e., low partial pressure of O), high temperature fluctuations, and low-pH, may be harbouring corals with a higher capacity for oxyregulation, rendering them more resilient to adapt to life in low-pO surroundings. We investigated differences in the hypoxic response of the common reef-building coral Pocillopora acuta following 1-year transplantation between Low Isles reef flat (a comparatively more stable O environment) and Woody Island mangrove lagoon (a more variable and oftentimes low-pO habitat), on the Great Barrier Reef. Analysing hypoxia response curves and metabolic function and physiology, we found that mangrove P. acuta retained attributes for hypoxic tolerance when transferred between habitats. These corals survived frequent low-pO exposure (
