“…Variations in the microbial composition may be another reason. Chen et al (2015) found functional changes of soil organisms under different thinning treatments in the same sites and at the same time. The increase in the b-glucosidase activity in the thinning treatments in January might be attributable to variations in the microclimate.…”

“…However, long-term thinning practices have been reported to increase soil carbon by enhancing root system decomposition in thinned trees and understory growth after canopy removal (Selig et al, 2008). Despite an abundance of studies about the effects of thinning on the total SOC of the forest floor, few have examined how thinning influences labile carbon pools and carbon cycle-related enzymes in the mineral soil (Chiang et al, 2010;Geng et al, 2012;Chen et al, 2015), and the results are still controversial. For example, Bolat (2014) and found thinning increased labile organic carbon, but decreases have been reported in other studies (Schilling et al, 1999;Hassett and Zak, 2005).…”

“…Related literatures available support evidences for this viewpoint. For instance, soil microbial biomass increased after gap creation (Bolat, 2014;Chatterjee, Vance, Pendall, & Stahl, 2008;Chen et al, 2015;Lewandowski et al, 2015). However, most of these reports come from tropical, subtropical and temperate forests.…”

Although the effects of gap formation resulting from thinning on microclimate, plant generation and understory plant community have been well documented, the impact of thinning on soil microbial community and related ecological functions of forests particularly in subalpine coniferous region is largely unknown. Here, the effects of thinning on soil microbial abundance and community structure using phospholipid fatty acid (PLFA) in pine plantations were investigated 6 years after thinning. The experimental treatments consisted of two distinct‐sized gaps (30 m2 or 80 m2 in size) resulting from thinning, with closed canopy (free of thinning) as control. Soil temperature as well as the biomass of actinomycete and unspecific bacteria was sensitive to gap formation, but all these variables were only responsive to medium gap. Nonmetric multidimensional scaling confirmed that soil microbial community was responsive to gap size. In addition, gap size exerted contrasting effect on bacteria‐feeding nematode and fungi‐feeding nematodes. In conclusion, thinning‐induced gap size would affect soil microbial community through changing soil temperature or the abundance of fungi‐feeding nematodes.

“…The release of labile N from dead microbial biomass and plant roots could also be a contributing factor in the observed variation in soil inorganic N content [57]. Under decreased precipitation, increased soil microbial biomass mortality is expected, as is as dying plant roots due to drought, which releases labile N into the soil and contributes to the accumulation of inorganic N [9,44,58].…”

Expected changes in precipitation over large regions of the world under global climate change will have profound effects on terrestrial ecosystems in arid and semiarid regions. To explore how changes in the amount of precipitation in the growing season would affect soil nitrogen (N) availability in a semiarid ecosystem, we established rainout shelters and irrigation systems by simulating 30% reduced (DRY) and 30% increased precipitation (WET) relative to natural precipitation (Control) to measure some key soil process properties for two growing seasons in a nutrient-poor Mongolian pine (P. sylvestris var. mongolica) plantation. Both WET and DRY treatments significantly affected monthly soil inorganic nitrogen concentrations, which showed a higher inorganic N under DRY than Control in each month and lower in WET than Control. Monthly soil microbial biomass N content was reduced by DRY and raised by WET treatments. The results indicated the asynchrony of the availability of soil moisture and soil nutrients in Mongolian pine plantations at the Horqin Sandy Lands in Northeast China. Water limited plant growth in Mongolian pine plantations when precipitation decreased, and nitrogen limitation became increasingly important when precipitation increased. Accumulation of N in microbial biomass is an important mechanism for N cycling in this ecosystem. To effectively manage Mongolian pine plantations, it is advised that evapotranspiration is minimized when precipitation decreases and that there is an increase in soil N availability by protecting litterfall when precipitation increases.
