Trees as net sinks for methane (CH₄ ) and nitrous oxide (N₂ O) in the lowland tropical rain forest on volcanic Reunion Island.

ABSTRACT: Trees are known to emit methane (CH₄ ) and nitrous oxide (N₂ O), with tropical wetland trees being considerable CH₄ sources. Little is known about CH₄ and especially N₂ O exchange of trees growing in tropical rain forests under nonflooded conditions. We determined CH₄ and N₂ O exchange of stems of six dominant tree species, cryptogamic stem covers, soils and volcanic surfaces at the start of the rainy season in a 400-yr-old tropical lowland rain forest situated on a basaltic lava flow (Réunion Island). We aimed to understand the unknown role in greenhouse gas fluxes of these atypical tropical rain forests on basaltic lava flows. The stems studied were net sinks for atmospheric CH₄ and N₂ O, a
