Conclusion
The CO2 emissions from termite mounds were generally
higher than surrounding soils. The mound CO2 emission,G. sulphureus and M. crassus are major CO2producers among the non-fungus growing termites in this tropical forest.
The difference in CO2 emissions among termite mounds may
due to the population colony, ventilation, and thickness of the nests.
The rate of soil CO2 emission was increased with
increasing soil moisture content. Future information regarding the total
soil CO2 emission and the mound density on large scale
as well as their environmental conditions are necessary for evaluating
the contribution to the total soil respiration in Thai-tropical forest.
