Abstract:

In order to reveal composition of faunal communities in deep soil, we investigated soil at 30 and 55 cm at the Olympic Campus of the Chinese Academy of Sciences in a suburb of Beijing using trap collectors. A total of 10,163 individuals representing 20 orders belonging to ten classes and three phyla were captured in eight surveys carried out over five years. The dominant groups were Hymenoptera (61.0%), Acarina (12.1%) and Collembola (11.2%). The individuals and groups in the 30 cm soil layer were greater than at 55 cm. The dominant group of the 30 cm soil layer was Hymenoptera (69.4%) while at 55 cm, Hymenoptera (45.7%), Acarina (21.8%) and Collembola (16.4%) were all dominant. The number of individuals and groups recorded from April to October was greater than October to April of the next year. Annelida appeared only between October to April of the next year, while Thysanoptera, Psocoptera, Dermaptera appeared only between April to October. The lowest Jaccard value of soil faunal communities in different vegetation forms was 0.75. None of Shannon-Wiener diversity index, Simpson dominance index and Pielou evenness index showed significant differences between different vegetation types (P > 0.05). The results showed that there were abundant soil faunal communities in deep soil. The number of individuals and groups decreased with increasing soil depth. Soil faunal community structure was different in different seasons and the composition was highly similar between different vegetation types.
