Effects of Pneumatophore Density on Methane Emissions in Mangroves

Mangroves play an important role in carbon sequestration. However, mangroves can be sources of greenhouse gas (GHG) emissions. In this study, methane (CH4) emissions and related soil properties were determined multiple Taiwan, including Kandelia obovata Avicennia marina mangroves. K. possess prop roots, whereas pneumatophores are found A. marina. Our results showed that mangrove soils significant CH4 emissions, which should accounted for budgets. particular, the approximately 50- to 100-fold those adjoining mudflats. Multiple regression analyses indicated salinity pH redox potential organic content mudflats key factors affecting pneumatophore density alone explained 48% variation More resulted higher Thus, compared with assessed properties, contribution transportation from was more significant. addition our demonstrated root structure may also affect GHG
