Although tropical forest soils contributed substantially global soil methane uptake, observations on soil methane fluxes in tropical forests are still sparse, especially in Southeast Asia, leading to large uncertainty in the estimation of global soil methane uptake. Here, we conducted two-year (from Sep, 2016 to Sep, 2018) measurements of soil methane fluxes in a lowland tropical forest site in Hainan island, China. At this tropical forest site, soils were substantial methane sink, and average annual soil methane uptake was estimated at 2.

- The study investigates how the ratio of intercellular to ambient CO concentrations (c/c) varies in a rubber tree ecosystem and identifies factors influencing these variations.
- It finds that c/c is not constant; there is a "V"-shaped diurnal pattern and that it changes across environmental gradients, particularly being influenced by water vapor pressure deficit (D).
- A simpler model based on D was as effective in predicting c/c as more complex models, suggesting that incorporating longer-term factors like soil water content can enhance predictions of c/c.
