Faunal composition of meio- and macroinvertebrates associated with aquatic macrophytes in Central Kalimantan and West Java, Indonesia, with special reference to oligochaetes

Abstract

Composition of meio- and macroinvertebrates associated with aquatic macrophytes was compared between acid waters in a peat swamp area of Central Kalimantan (CK) and neutral waters in West Java (WJ). Among the invertebrate assemblages, cladocerans and/or copepods dominated in both regions. On the other hand, relative abundances of chironomids and ostracods were significantly higher in CK and WJ, respectively. Eighteen taxa of oligochaetes were recorded from the regions, of which 14 ones belonged to the subfamily Naidinae of the family Tubificidae. The oligochaete composition was quite different between CK and WJ, in that Pristina species dominated in CK, while Stylaria fossularis dominated in WJ. WJ harbored more diverse oligochaetes than CK. The difference in oligochaete composition is related to water acidity.
