Seagrasses Continue to Emit Methane Decades After Death
Alejandra Manjarrez, PhD | Feb 22, 2022 | 4 min read
Methane production, likely achieved by a diverse group of methanogenic archaea, occurs at similar rates in both alive and dead seagrasses, a study reports. The findings highlight the potential environmental impact of seagrasses declining globally.
