Discussion
Large number of soil animal study sites have been established in different regions worldwide (Yin et al., 2010; Wu et al., 2011), and many scholars have studied soil fauna on their ecological function (Lubbers et al., 2020) and soil animal coexistence mechanisms (Stefanie et al., 2015; Guo et al., 2018). However, most of these studies were on reginal or population scales (Marchen et al., 2015; Song et al., 2017; Phillips et al., 2019). There is a lack of studies that analyze communities with broad ranges of taxa on large scales. Various ecosystems worldwide are interconnected. Thus, integrating comparative large-scale analyses could better reveal the laws of soil fauna community distributions and species coexistence mechanisms.
