Physical and hydric factors regulating nitrous oxide and methane fluxes in mountainous Atlantic forest soils in southeastern Brazil

Linking above and belowground carbon sequestration, soil organic matter properties, and soil health in Brazilian Atlantic Forest restoration

“…Our primary forest area showed at least 30% higher pmoA gene abundance in the topsoil layer than other sites (Figure S4). Our findings are consistent with other studies showing that undisturbed upland tropical forests serve as substantial and persistent CH 4 sinks (Fernandes et al, 2002;Zhao et al, 2019;Siqueira-Neto et al, 2021;Mombrini et al, 2022). However, the non-native vegetation areas are also oxidizing C-CH 4 in the soil, with emphasis on the 15-year-old restoration (− 61.9 μg m − 2 h − 1 ).…”
