  abstract = {{T}his study aims to improve our understanding of temporal variations and controlling factors of soil respiration ({R}-s) and its components (microbial respiration or {R}-m and root respiration or {R}-b) in an {A}sian tropical seasonal forest at diurnal, seasonal and annual timescales in relation to biotic and abiotic controls. {R}-s was studied by the trenching method in a seasonal dry diptercarp forest, western {T}hailand. {A}n automated soil chamber system was used to produce hourly data of {R}-s during 2008-2011. {A}nalysis of {R}-s in relation to both biotic and abiotic factors was carried out to understand its temporal variations at different timescales. {R}-m was the main contributor to overall magnitude and variability of {R}-s. {S}oil temperature alone was the main driver of diurnal variation, while the combination of soil moisture and soil temperature determined the seasonal variations. {T}he amount of {R}-s was also related to the fine root (< 2 mm) and microbial biomass at seasonal timescales. {D}ue to the small inter-annual variations in soil temperature and moisture, total soil respiration among the 4 years was not significantly different (p < 0.05). {T}he annual totals for {R}-s during 2008-2011 were 3.20, 3.89, 3.52, 4.14 kg{CO}(2) m(-2) years(-1), respectively. {T}he 4-year average ratio of {R}-m (trenched) to {R}-s (untrenched) was 66 +/- 4 %. {R}-m plays a crucial role in determining the magnitude (large ratio between {R}-m and {R}-s) and temporal variations of {R}-s. {I}n this forest ecosystem, high seasonal variations in {R}-s were observed and were mainly attributed to the response of {R}-m to moisture.},
