Abstract:

Aims: Global environmental change leads to increasing biodiversity loss, and soil animal communities are among the most species-rich components of terrestrial ecosystems. One of the most important biodiversity-ecosystem functioning experiments was designed in subtropical China (referred to as BEF-China). Here, we investigate the change of oribatid mite community structures in different tree species forests (site A and site B) of BEF-China.
Methods: Soil samples from BEF-China were collected from September 2019 to April 2022. The abundance, diversity, community structure, and ecological indices of oribatid mite communities as well as environmental factors were analyzed and compared between forests with different tree compositions.
Results: We found that, (1) the community structure of oribatid mites in each forest was significantly different. The relative abundance of Oppiidae, Lohmanniidae, Oribatulidae, and Microzetidae was higher in site A than site B; and the relative abundance of Scheloribatidae, Tectocepheidae, and Trhypochthoniidae was higher in site B than site A. (2) There were different seasonal dynamics of oribatid mite communities among the four seasons. In site A, the abundance, species richness, and Shannon diversity of oribatid mites in summer and autumn were markedly lower than those in spring and winter. However, the diversity of oribatid mites in spring and autumn were similar in site B. (3) There were distinct correlations between oribatid mite communities and environmental factors. And yet, different oribatid mite species have varied responses to indicated factors.
Conclusion: The results highlight that oribatid mite community structures are impacted by aboveground plants. This research provides a reference for future researchers to help understand the biotic interactions between soil oribatid mites and plants.
