Abstract:

Identifying spatial patterns and assembly rules in communities is a central study topic in ecology. With the unprecedented rate at which biodiversity is decreasing, it is necessary to recognize the spatial patterns and assembly rules in communities in order to understand why biodiversity is being lost and to be able to protect it. However, previous studies have focused more on plant communities in above-ground terrestrial ecosystems, neglecting below-ground ecosystems, especially soil faunal communities. Indeed, soil faunal biodiversity is a crucial component of global biodiversity because soil faunal communities assist in the maintenance of important ecosystem structures and functions. Therefore, one important aim of identifying spatial patterns and assembly rules in soil faunal communities is to clarify mechanisms of maintaining soil faunal biodiversity at multiple scales, so as to promote these processes, which also maintain ecosystem structures and functions. Soil faunal communities usually form complicated spatial patterns at multiple spatial scales. Here, we propose spatial autocorrelation characteristics, and then show how the complicated spatial patterns are demonstrated by patches and gaps of soil faunal communities at multiple scales. These spatial patterns are mainly controlled by processes of biotic interactions, environmental filtering and random dispersal. Consequently, we discuss the impacts of these processes on soil faunal communities. Finally, we suggest that these three processes are essential to evaluate and construct a theoretical framework for soil faunal communities and should continue to be studied in the future. Because interest in spatial patterns and assembly rules of soil faunal communities is relatively new in China, we expect this review will promote the development of related research areas.
