Presently, an incomplete mechanistic understanding of tropical reef macroalgae photosynthesis and calcification restricts predictions of how these important autotrophs will respond to global change. Therefore, we investigated the mechanistic link bet

Water column hypoxia, low tissue pO2 and H2S intrusion, a known phytotoxin, are linked to global seagrass decline. While many lab experiments have examined these relationships, only field studies capture the complexity of gas dynamics in situ. We exa

Seagrasses in estuaries and coastal zones globally are subject to multiple stressors including high temperature, hypersalinity, hypoxia, sulfide (H2S) toxicity, algal blooms, and extreme climatic events, all likely to increase under climate change. T
