Distribution pattern of soil mite community in litter layer and soil layer along altitude gradient in Tianmu Mountain
It is an important topic to clarify the distribution pattern of soil mites along the mountain altitudinal gradient in soil zoology research and is the core of the corresponding study on mountain soil fauna related to global changes.However,the current study mainly focused on soil mites in the soil layer,ignoring those that are more diverse in the litter layer,which were higher than that in the soil layer.To illustrate the distribution pattern of soil mites along the altitudinal gradient in both the litter layer and the soil layer,soil mite samples were analyzed from 12 sample plots along 364.33 m to 1 476.29 m in Tianmu Mountain in May 2021.The results indicate that(1)A total of 7 172 soil mite individuals with 84 species were captured,and the dominant species was Haplozetes paraminimicoma.Species diversity in the litter layer was significantly higher than that in the soil layer.(2)In the litter layer,the Margalef richness index,Shannon-Wiener diversity index and Simpson dominance index all varied significantly along the altitudinal gradient with a unimodal distribution,while each diversity index in the soil layer they did not vary significantly along the altitudinal gradient.The results of this study suggest that the distribution patterns of soil mite diversity along the altitudinal gradient differ between the litter layer and the soil layer.This suggests that a study on the altitudinal gradient of soil faunal diversity in both the litter layer and soil layers in subtropical mountains will provide richer basic data on the diversity of soil faunal communities in mountains corresponding to global changes.
