摘要:

The effect of soil warming and precipitation control in the context of soil warming on Collembola community was studied in Songnen grassland, China. Treatments included (1) control; (2) soil warming; (3) soil warming with low precipitation; and (4) soil warming with high precipitation. The open top chambers were used to increase the soil temperature, and the low and high precipitation were created by covering 30% of the chamber and artificial addition after rainfall through the three-year long field experiment. Soil samples were taken and collembolans were extracted in the 15th in June, August and October from 2010 to 2012. Abundance of total Collembola and dominant morphospecies Orchesellides sp.1 was significantly increased by soil warming. Total Collembola abundance was not affected by the precipitation. However, the abundance of Mesaphorura sp.1 was significantly increased by warming with low precipitation treatment. Collembola species richness, diversity and evenness were not impacted by any treatment through all the sampling times. These results suggest that more attention should be paid to the Collembola community variation under global warming in the future.
