【 摘 要 】

Agroforestry system enhanced ant biodiversity. Ant structure in the ecosystem has been driven by many factors, e.g., competition and predation among species. Dominant species and predator may give impact to species diversity in the ecosystem. We had field research to examine the interactions among dominant ant species, predator Oecophylla smaragdina, and other ants in Tarakan, North Kalimantan. In agroforestry system as the study site, ants and other insects on 66 crop trees were collected by sweeping and beating. The obtained number of two species Tapinoma melanocephalum and Oecophylla smaragdina occupied more than 60% of all collected ants. Two dominant ants tended to be separately distributed. The community structure may be ant mosaic pattern. Furthermore, the densities of the two dominant ants were higher, but their diversities in the tree were lower than dominant species and predator absence. Probably, the tendency seems to be active on the distribution of other ants.
