[Soil microarthropods and macrofauna in monsoon tropical forests of Cat Tien and Bi Dup-Nui Ba National Parks, Southern Vietnam].
The abundance, biomass, vertical distribution, and taxonomic composition of soil invertebrates (springtails, macrofauna, and termites) were studied in forest formations differing in edaphic and climatic conditions: lowland forests dominated by Lagerstroeomia spp. or Dipterocarpus spp. in the Cat Tien National Park and in a mountain pine (Pinus kesiya) forest on the Da Lat Plateau, southern Vietnam. In the lowland forests, springtails had a relatively low density (10000-12000 ind./m2), but their diversity was high (41-43 species in each forest). The density of large soil invertebrates (without ants and termites) reached 500-700 ind./m2 at a biomass of approximately 30 g/m2 (with earthworms accounting for up to 230 ind./m2 and 19-28 g/m2). Among termites, species of the genera Macrotermes and Odontotermes were dominant. Their total biomass in some areas exceeded 15-20 g/m2. In the mountain pine forest, the total biomass of soil macrofauna was approximately 11 g/m2, the abundance and diversity of springtails were low (7500 ind./m2, 28 species), and wood-destroying species of the genera Schedorhinotermes sp. and Coptotermes sp. dominated among termites.
