An increase in atmospheric CO₂ levels and global climate changes have led to an increased focus on CO₂ capture mechanisms. The in situ quantification and spatial patterns of forest carbon stocks can provide a better picture of the carbon cycle and a deeper understanding of the functions and...

Partitioning soil respiration (R_s) into heterotrophic (R_h) and autotrophic (R_a) compartments is an important first step in understanding the response of soil carbon flux to changes in climate. This is because R_h and R_a respond differently to changing environmental conditions. However, the methods...

Forest soils in the warm-humid tropics significantly contribute to the regional greenhouse gas (GHG) budgets. However, spatial heterogeneity of GHG fluxes is often overlooked. Here, we present a study of N₂O and CH₄ fluxes over 1.5 years, along a topographic gradient in a rainforest catchment in...

The temperature sensitivity (Q₁₀) of soil microbial respiration (Rs) is a critical parameter for predicting soil carbon (C) fluxes under changing climatic conditions, and labile C is continuously input into soil via root exudates or plant litter in field. However, how Q₁₀ responds to labile C input ...

Seasonally-flooded várzea forests of Western Amazonia are one of the most productive and biodiverse wetland forests in the world. However, data on their soil CO₂ emissions, soil organic matter decomposition rates, and soil C stocks are scarce. This is a concern because hydrological changes are...

Although agriculture and livestock systems represent important sources of N2O from the soil, they may also aid in emissions mitigation, mainly when integrated systems are taken into account, such as crop-livestock-forest, for food production. This work assessed the soil N2O emissions from a ...

Soil carbon (C) stabilization has become an important topic in recent years in the context of global climate change. Increasing evidence suggests that microbial residues represent a significant fraction of persistent soil C pools. However, patterns and determinants of soil microbial residues across ...

Tropical montane cloud forests contain a large abundance and diversity of canopy epiphytes, which depend on canopy soil to retain water and nutrients. We lack an in depth understanding of how these soils contribute to ecosystem processes and soil diversity and how sensitive they may be to projected ...

Climate changes and human-mediated modifications to ecosystems have threatened the biodiversity and habitats of various species. Dacrydium pectinatum is a constructive and endangered species in the tropical mountain forests of Hainan Island, China. In this study, we established sixty-eight 30 m ×...

Increasing forest soil organic carbon (SOC) storage is important for reducing carbon dioxide (CO₂) emissions from terrestrial ecosystems and mitigating global climate change. Although the effects of altitude, temperature and rainfall on organic carbon have been studied extensively, it is difficult...
