description: | Aim This study aims to improve our understanding of temporal variations and controlling factors of soil respiration (Rs) and its components (microbial respiration or Rm and root respiration or Rb) in an Asian tropical seasonal forest at diurnal, seasonal and annual timescales in relation to biotic and abiotic controls. Methods Rs was studied by the trenching method in a seasonal dry diptercarp forest, western Thailand. An automated soil chamber system was used to produce hourly data of Rs during 2008–2011. Analysis of Rs in relation to both biotic and abiotic factors was carried out to understand its temporal variations at different timescales. Results Rm was the main contributor to overall magnitude and variability of Rs. Soil temperature alone was the main driver of diurnal variation, while the combination of soil moisture and soil temperature determined the seasonal variations. The amount of Rs was also related to the fine root ( |
