Climate change models predict more frequent and severe droughts in the humid tropics.
How drought will impact tropical forest carbon and greenhouse gas dynamics is poorly …

Humid tropical forests have the fastest rates of organic matter decomposition globally, which
often coincide with fluctuating oxygen (O2) availability in surface soils. Microbial iron (Fe) …

Core Ideas Movement of O2 in the soil is mainly diffusive. Respiration consists of plant root
and microbial O2 uptake, roughly of the same magnitude. Reduced O2 and elevated CO2 …

Lignocellulosic biofuels are promising as sustainable alternative fuels, but lignin inhibits
access of enzymes to cellulose, and by-products of lignin degradation can be toxic to cells …

Humid tropical forests support large stocks of surface soil carbon (C) that exhibit high spatial
variability over scales of meters to landscapes (km). Reactive minerals and organo-metal …

While the contribution of iron (Fe)-bearing minerals to organic carbon (C) stabilization in
terrestrial systems is well-described, the influence of Fe solid-phase speciation on …

Humid tropical forests are among the most productive ecosystems globally, yet they often
occur on soils with high phosphorus (P) sorption capacity, lowering P availability to biota …

Soils are large sources of atmospheric greenhouse gases, and both the magnitude and
composition of soil gas emissions are strongly controlled by redox conditions. Though the …

Progress in understanding changes in soil biology in response to latitude, elevation and
disturbance gradients has generally lagged behind studies of above-ground plants and …
