确定了白蚁的稳定（δ 13 C和δ 15 N）和放射性（14 C，137 Cs和210 Pb）同位素，
是从泰国的一片干燥的万年青森林中采集的。根据δ 13 C和δ 15 N值，将一种食木白蚁（Microcerotermes crassus）与土栖白蚁（Termes propinquus）、土栖白蚁（Termes comis）和双尖白蚁（Dicuspiditermes makhamensis）区分开来。在泰国的Termes组的δ 13 C和δ 15 N值的多样性小于澳大利亚，那里的'Termes'组的食性更多样化。其他土栖白蚁产生类似的δ 13 C值，但δ 15 N值的范围更大。14 C百分比现代碳（pMC）值表明，土壤喂养的白蚁比木材喂养的白蚁使用更年轻的碳，这与来自喀麦隆，中非的白蚁是一致的。δ 13 C和14 C-pMC值表明，土食白蚁D. makhamensis，在使巢土丘，和更深的土壤（10-30厘米）由真菌生长的白蚁，Macrotermes carbonarius。210 Pb和137 Cs在白蚁体内几乎没有掺入，而214 Pb在工蚁体内则有回收。结果表明，稳定同位素和放射性同位素在食虫动物、有机质分解和生态系统工程研究中具有重要意义。
Stable (δ13C and δ15N) and radio- (14C, 137Cs and 210Pb) isotopes were determined for termites that
have been sampled from a dry evergreen forest in Thailand. A wood-feeding termite, Microcerotermes crassus, was separated from soil-feeders: Termes propinquus, Termes comis and Dicuspiditermes makhamensis by δ13C and δ15N values. The Termes group in Thailand had less diverse values in δ13C and δ15N than those in Australia, where the feeding habits of the ‘Termes’ group are more diverse. Other soil-feeding termites produced similar δ13C values, but a larger range in δ15N values. 14C-percent modern carbon (pMC) values suggest that the soil-feeding termites used younger carbon than the wood-feeding termites, and this was consistent with the termites from Cameroon, central Africa. Values of δ13C and 14C-pMC indicate that surface soil was used by a soil-feeding termite, D. makhamensis, in making the nest mounds, and deeper soil (10–30 cm) by a fungus-growing termite, Macrotermes carbonarius. 210Pb and 137Cs were scarcely incorporated into the termites, although 214Pb was recovered from the workers. The results suggest that stable- and radioisotopes are useful in the study of detritivorous animals, organic matter decomposition and ecosystem engineering.
