Abstract:

Soil fauna play an important role in terrestrial ecosystems. They are closely connected with the above and under ground ecosystems. The effect of basalt platform on the diversity and ecological geographic distribution of the below ground soil fauna is unknown. In the present study, an investigation of diversity and ecological geographic distribution of the below ground soil fauna was conducted in the basalt platform of the Changbai Mountains with four habitats types (original conifer and broad-leaved mixed forest, secondary conifer and broad-leaved mixed forest, secondary deciduous broadleaved forest and arable land). The plots (5 m×5 m) were established using permanent signs in each of the arable land. The plots (20 m×20 m) were established using permanent signs in each of the other three habitats types. Within each plot, five subplots were selected randomly, and 25 cm×25 cm and 10 cm×10 cm areas were collected from the litter layer, 0-10 cm, 10-20 cm and 20-30 cm soil layers in each subplot during spring, summer, and autumn 2014. Soil macrofauna and soil meso-microfauna were extracted from each of the soil samples using hand collection methods and Tullgren funnel extractor, respectively. The effects of habitat types, seasonal variations and soil layers on the abundance, richness of soil fauna were analyzed using one-way ANOVA and multivariate analysis. Indexes of diversity were calculated to describe the characteristics of the diversity of soil fauna. The influence of soil environmental factors on soil faunal diversity was examined using redundancy analysis (RDA). The results showed that the dominant groups were Isotomidae, Oribatida and Hypogastruridae. The common groups included Gamasida, Actinedida, Pseudachorutidae, Diptera larva, Sminthuridae and Tomoceridae. In spring, the secondary conifer and broad-leaved mixed forest had the highest diversity of soil macrofauna among the four habitats. For soil macrofauna, in summer and autumn, original conifer and broad-leaved mixed forest had the highest diversity among the four habitats. However, in spring, summer, and autumn, the arable land had the lowest diversity among the four habitats. For soil meso-microfauna, in spring and autumn, original conifer and broad-leaved mixed forest had the highest diversity among the four habitats. In summer, secondary conifer and broad-leaved mixed forest had the highest diversity among the four habitats. However, in spring, summer, and autumn, the arable land had the lowest diversity of soil meso-microfauna among the four habitats. The one-way ANOVA showed that a significantly lower abundance and richness of soil fauna was evident in the arable land when compared to all other habitats in spring, summer, autumn (P < 0.05). However, abundance and richness of soil fauna did not respond significantly to variations in seasons (P > 0.05). From the vertical distribution, the diversity of soil fauna in each habitat was shown that it was decreased with the increasing soil depth. Redundancy analysis (RDA) showed that diversity and ecological geographic distribution of the below ground soil fauna was correlated significantly with soil temperature, available P, organic matter, soil moisture.
