According to a recent study on shallow-water ecosystems, by 2100, mangroves, tidal marshes, and coral habitats could all significantly diminish due to climate change and coastal land usage, whereas seagrass meadows could expand and macroalgal beds might remain steady. The results of this study are published in the open-access journal PLOS Climate by Hirotada Moki and colleagues from the Port and Airport Research Institute in Japan.
