Data sets
Biogenic Volatile Organic Compounds (BVOC) and methane fluxes, microbial biomass, physical and chemical properties of the soil-litter compartment across three forest types in central Amazonia D. Pinheiro de Oliveira et al. https://doi.org/10.17871/ATTO.651.6.2645
Short summary
Forests release trace gases that influence air and climate. While plants are the main source, soil and leaf litter can also release significant amounts, especially in tropical forests like the Amazon. We measured these fluxes in different forest types and found soil and litter to be active sources and sinks. This can improves climate models by including realistic forest processes, vital for understanding and protecting the Amazon.
