Soil organic matter (SOM) quantity and quality can be directly altered by climate, and SOM has been proposed as both a significant source and sink of carbon dioxide. To understand the factors that influence SOM, the present study focuses on the relationship between precipitation and soil physical...

The temperature response of soil microbial respiration (R_h) is of significance, with the optimum temperature of R_h being the key parameter for accurately modeling how it responds to temperature change under climate warming scenarios. However, knowledge about T_opt in natural ecosystems remains...

Organic carbon saturation in soils refers to the theoretical maximum soil organic carbon (SOC) that can be associated with and stabilized on fine silt plus clay particles (F <20 µm). We reviewed the literature dealing with SOC distribution between soil fractions to evaluate carbon saturation for tropical soils and estimate the C storage potential of cropland. We collected 258 data points on SOC distribution between...

Climate change mitigation and food security are two of the main challenges of human society. Agroforestry systems, defined as the presence of trees on external and internal boundaries, cropland, or on any other available niche of farmland, can provide both climate change mitigation and food. There...

Methane (CH₄) is one of the most potent greenhouse gases. Although forest and grassland soils generally consume atmospheric CH₄, the quantities and spatiotemporal changes in CH₄ uptake remain largely uncertain for these ecosystems at the global scale. In this study, we developed an empirical model...

Soil respiration is a key ecosystem function whereby shifts in respiration rates can shift systems from carbon sinks to sources. Soil respiration in permafrostassociated systems is particularly important given climate change driven permafrost thaw that leads to significant uncertainty in resulting...

We selected Katerniaghat Wildlife Sanctuary in which five plant community structures (PCSs) were identified namely dry miscellaneous forest, sal mixed forest, teak plantation, lowland miscellaneous forest and savanna whose response in physical, chemical and microbial soil properties were assessed....

This study aims to assess the carbon storage capability of dominant vegetative land covers in Thailand by estimating biomass, biomass carbon and soil carbon stocks. Above-ground biomass was estimated from allometric equation or actual raw yield. Soil organic carbon was analyzed according to the...

Background: Consistent long-term declines in net aboveground biomass change have been reported in some boreal and tropical forests. Global change-type drought (i.e., demands of increased evapotranspiration exceeding soil water reserves) has been identified as the main driver for these declines....

Background: The environmental stresses caused by climate change have become more severe in recent decades, affecting tree growth and physiology. Tropical forests have great potential for global carbon sequestration. However, they suffer from heavy rainfall and prolonged dry periods due to climate...
