Abstract:

Harvest ant nests are an important microhabitat in desert ecosystem that greatly affect the distribution and diversity of animals and plants by improving the vegetation and soil environment. In view of this, this paper selected gobi Messor desertus ant nests as the research object. We investigated the assemblage of five typical ground arthropod taxa, namely spiders, beetles, ants, mites and springtails in ant nest and adjacent bare ground microhabitats using pitfall traps in autumn. This study combined with the changes of vegetation and soil environmental factors to analysis the effects of M. desertus activities and their nests on the diversity of five ground arthropods. The key results were as follows. The activity density, groups richness and diversity index of ground arthropods were significantly higher in ant nests than in adjacent bare ground microhabitats in autumn, which were 2.9 times, 2.5 times and 4.5 times respectively; Arachnida, Acarina and Collembola community composition of ant nests and adjacent bare ground differed significantly. Ant nest microhabitats significantly increased the activity density and groups richness of Arachnida and Collembola, and the activity density of Arachnida was positively correlated with the activity density of Collembola; pRDA showed that soil electrical conductivity, soil clay, total nitrogen, total phosphorus and total potassium content were the main soil factors driving the distribution of ground arthropod communities between ant nest and adjacent bare ground microhabitats. In conclusion, M. desertus nests strongly affect the aggregation of ground arthropods such as Arachnida, Acarina and Collembola in autumn by enriching resources and improving the soil environment, while the activities of Coleoptera (such as Histeridae and Geotrupidae) and Formicidae are insensitive to the presence of ant nests.
