Abstract

Abstract:

Nitrogen deposition and precipitation changes have great impacts on desert steppe ecosystems. In order to investigate the different effects of nitrogen deposition and precipitation changes in different time frames on the structure and diversity of soil meso- and micro- fauna communities under desert steppe， simulation experiments were set up in 2015 in the Stipa breviflora desert steppe of Siziwangqi， Inner Mongolia， with three moisture gradients of reduced rainfall （R）， natural precipitation （CK）， and increased rainfall （W） as main plots， and N₀， N₃₀， N₅₀， and N₁₀₀ nitrogen levels as subplots in a split-plot experiment. Soil fauna changes were analysed by comparing data for 2016 and 2020. It was found that 553 soil meso- and micro- fauna， belonging to 10 orders and 46 families of Arthropoda， were captured and isolated in the sample plots in 2016； 1211 soil meso- and micro- fauna， belonging to 13 orders and 41 families of Arthropoda， were captured and isolated in the sample plots in 2020， of which 24 families were different from those in 2016. Under the R treatment the highest number of captures were made under the N₃₀ treatment in 2016， and the highest number of captures were made under the N₅₀ in 2020. The ratio of individual density of soil meso- and micro-fauna in the 0-10 cm soil layer to that in the 10-20 cm soil layer was 3.98 in 2016， and was 1.83 in 2020-a decrease of 54% compared with 2016. The diversity index and richness index in 2020 under the WN₅₀ and WN₁₀₀ treatments were higher than those in 2016， and the dominance index in 2020 under CKN₅₀ and CKN₁₀₀ treatments was lower than in 2016. The results of principal coordinates analyses showed that moisture treatments had a more significant effect on the distribution of soil meso- and micro-fauna in the desert steppe （P<0.05）； and the results of redundancy analyses showed that the correlation between soil pH and soil fauna diversity and quantity indicators was enhanced after 5 years of changed water and nitrogen availability. In summary， under the background of global change， precise regulation of soil pH can further influence the ecological functions of soil fauna in soil ecosystems.
