Effects of different nitrogen additions on soil microbial communities in different seasons in a boreal forest

摘要: In the global change scenario, nitrogen (N) deposition has potential to affect soil microbial communities that play critical roles in ecosystem functioning. Although impacts of N on have been reasonably well studied, microorganism responses addition combined with seasonal rarely reported. This study was conducted evaluate effects different levels (0, 2.5, 5.0, and 7.5 g N·m−2·yr−1) seasons (spring, summer, autumn) a boreal forest. Our results showed physical–chemical properties were found be changed by changes correlated community structure. The significantly diversity abundance community, while their interactions only bacterial fungal diversity. addition, our also provided clear evidence for specific microorganisms additions each season. findings suggest response could will strongly correlate environmental change.
