Research Abstract

Recent studies reported that there can be hot spots of soil respiration(extremely high efflux of CO_2 from the soil surface) in a tropical rainforest. Since the hot spots appear and disappear temporally and spatially, nesting and feeding activity of ants and termites could be a source of the hot spots. In this study, therefore, we aimed to 1) determine the hot spots of soil respiration in a dry evergreen forest in Thailand and 2) compare the CO_2 efflux from ant nests and surrounding soil in a tropical rain forest in Malaysia, in order to clarify the frequency of hot spot occurrence in tropical forests and impact of ants on the formation of hot spots. We found there were extremely high CO_2 efflux locations in the dy evergreen forest in Thailand suggesting the importance of this phenomenon for estimating carbon budget of the ecosystem accurately. The CO_2 efflux from the nests of ants were significantly higher than those of surrounding soil showing the ant nesting activity would be one of the reasons of the occurrence of hot spots in tropical forests.
