Comment : Soil respiration exhibited pronounced seasonal variations that clearly reflected those of soil water content, with minimum values below 1.6 µmol m- 2 s -1 at the end of the dry season in September and a maximum value of 5.6 µmol m- 2 s -1 after re-wetting in December. An empirical model describing the relationship between soil respiration and soil water content predicts the seasonal variations in soil respiration reasonably well (R2 = 0.88), even if the effects of soil temperature and soil water content may be confounded since both factors co-vary across seasons. Soil respiration was related neither to root biomass nor to soil carbon content, but was positively correlated with both leaf and total above ground litter (i.e. leaf, bark and woody debris).
