Microbes, marshes, and mangroves: Implications for coastal carbon storage

Salt marshes and mangroves are coastal ecosystems known to store excess carbon dioxide from the atmosphere, thus helping to reduce negative consequences of climate change. Despite their importance, the relative distribution of marshes and mangroves is changing due to increasing temperatures and sea level rise. It is unclear, though, what these shifts mean for carbon storage. Since microorganisms are crucial in soil carbon cycling, we need to better understand how they function in response to whether marshes or mangroves dominate. A research team in Florida set out to address this question, finding significant changes to the microbial community.
