Abstract:The objective of this study is to examine the effects of ant nesting activities on soil meso-micro arthropods communities in revegetated areas. Soil samples were collected from inside and outside of ant mounds in 5, 8, 34, and 57 years of revegetated areas in the southeastern edge of Tengger Desert. The soil meso-micro arthropods were extracted using the reformed Tullgren funnels. The community composition, and diversity distribution of soil meso-micro arthropods inside and outside of ant mounds and its influencing factors were examined alongside the succession of revegetated plantations. The results showed that: (1) The dominant groups of soil meso-micro arthropods include Isotoma, Hypogastrura, and Eupalopsellidae, which abundance were significantly higher inside than outside the ant mounds, since the 8th, 34th, and 57th years of revegetated respectively. The abundance of dominant groups and total abundance of soil meso-micro arthropods were significantly higher (P< 0.05) inside than outside the ant mounds since 8 years of revegetated areas. (2) The group richness and Shannon-Wiener diversity were significantly higher (P< 0.05) inside than outside ant mounds in 34 and 57 years of revegetated areas, with values 1.6 and 2.3 times higher in 34 years of revegetated areas, and 2.2 and 3.9 times higher in 57 years of revegetated areas, respectively; The Pilou index of soil meso-micro arthropods communities was significantly higher (P< 0.05) inside than outside of ant mounds in 57 years of revegetated areas alone. (3) Soil clay content was the factor driving soil meso-micro arthropods communities at early stage of the succession of revegetated plantations, whereas it was soil total nitrogen and total kalium content served as the driving factors at the middle and late stages. In conclusion, there were facilitative effects of ant mounds on soil meso-micro arthropod abundance alone at early stage of the succession of revegetated plantations, whereas there were no significant facilitative effects on total abundance and diversity of soil meso-micro arthropods until long-term succession occurred. Where, even there was significant effect on community structure of soil meso-micro arthropods in the microhabitats between inside and outside of ant mounds; in the end there was a radiating effect of ant mounds on the abundant distribution of soil meso-micro arthropods in the microhabitats outside of ant mounds.
