| 1 | Short-Term Effects of Experimental Warming and Precipitation Manipulation on Soil Microbial Biomass C and N, Community Substrate Utilization Patterns and Community Composition显示文摘Soil microorganisms are major drivers of soil carbon(C) cycling;however,the response of these microorganisms to climate change remains unclear.In the present study,we investigated how 18 months of multifactor climate treatments(warmed air temperature by 3℃ and decreased or increased precipitation manipulation by 30%) affected soil microbial biomass C and nitrogen(N),community substrate utilization patterns,and community composition.Decreased and increased precipitation significantly reduced microbial biomass C by 13.5% and 24.9% and microbial biomass N by 22.9% and 17.6% in unwarmed plots,respectively(P<0.01).Warming enhanced community substrate utilization by 89.8%,20.4%,and 141.4% in the natural,decreased,and increased precipitation plots,respectively.Particularly,warming significantly enhanced the utilization of amine and carboxylic acid substrates among all precipitation manipulation plots.Compared with the natural air temperature with natural precipitation treatment,other treatments affected fungal community richness by -0.9% to 33.6% and reduced the relative abundance of the dominant bacterial and fungal groups by 0.5% to 6.8% and 4.3% to 10.7%,respectively.The warming and/or precipitation manipulation treatments significantly altered Zygomycota abundance(P<0.05).Our results indicate that climate change drivers and their interactions may cause changes in soil microbial biomass C and N,community substrate utilization patterns,and community composition,particularly for the fungal community,and shifts in the microorganism community may further shape the ecosystems function. | Guanlin LI Seongjun KIM Minji PARK Yowhan SON | 2017 | Pedosphere2017，27，4： | 4 |
| 2 | Estimating the production and mortality of fine roots using minirhizotrons in a Pinus densiflora forest in Gwangneung,Korea显示文摘The aim of this study was to estimate fine root production(FP) and fine root mortality(FM) at 0–10,10–20,and 20–30 cm soil depths using minirhizotrons in a75-year-old Pinus densiflora Sieb.et Zucc.forest located in Gwangneung,Korea.We developed the conversion factors(frame cm-2) of three soil depths(0.158 for 0–10 cm,0.120 for 10–20 cm,and 0.131 for 20–30 cm) based on soil coring and minirhizotron data.FP and FM were estimated using conversion factors from March 26,2013 to March 2,2014.The annual FP and FM values at the 0–30 cm soil depth were 3200.2 and 2271.5 kg ha^(-1)yr^(-1),respectively.The FP estimate accounted for approximately 17 % of the total net primary production at the study site.FP was highest in summer(July 31–September 26),and FM was highest in autumn(September 27–November 29).FP was positively correlated with seasonal change in soil temperature,while FM was not related to that change.The seasonality of FP and FM might be linked to above-ground photosynthetic activity.Both FP and FM at the 0–10 cm depth were significantly higher than at 10–20 and20–30 cm depths,and this resulted from the decrease in nutrient availability with increasing soil depth.The minirhizotron approach and conversion factors developed in this study will enable fast and accurate estimation of the fine root dynamics in P.densiflora forest ecosystems. | Seung Hyun Han Soonjin Yun Jongyeol Lee Seongjun Kim Hanna Chang Yowhan Son | 2016 | Journal of Forestry Research2016，27，5： | 2 |
| 3 | Forest structure and carbon dynamics of an intact lowland mixed dipterocarp forest in Brunei Darussalam显示文摘Tropical forests play a critical role in mitigating climate change because they account for large amount o terrestrial carbon storage and productivity.However,there are many uncertainties associated with the estimation o carbon dynamics.We estimated forest structure and carbon dynamics along a slope(17.3°–42.8°)and to assess the relations between forest structures,carbon dynamics,and slopes in an intact lowland mixed dipterocarp forest,in Kuala Belalong,Brunei Darussalam.Living biomass,basa area,stand density,crown properties,and tree family composition were measured for forest structure.Growth rate,litter production,and litter decomposition rates were also measured for carbon dynamics.The crown form index and the crown position index were used to assess crown properties,which we categorized into five stages,from very poor to perfect.The living biomass,basal area and stand density were 261.5–940.7 Mg ha^(-1),43.6–63.6 m^2ha^(-1)and 6,675–8400 tree ha^(-1),respectively.The average crown form and position index were 4,which means that the crown are mostly symmetrical and sufficiently exposed for photosynthesis.The mean biomass growth rate,litter production,litter decomposition rate were estimated as11.9,11.6 Mg ha^(-1)a^(-1),and 7.2 g a^(-1),respectively.Biomass growth rate was significantly correlated with living biomass,basal area,and crown form.Crown form appeared to strongly influence living biomass,basal area and biomass growth rate in terms of light acquisition.However,basal area,stand density,crown properties,and biomass growth rate did not vary by slope or tree family composition.The results indicate that carbon accumulation by tree growth in an intact lowland mixed dipterocarp forest depends on crown properties.Absence of any effect of tree family composition on carbon accumulation suggests that the main driver of biomass accumulation in old-growth forests of Borneo is not species-specific characteristics of tree species. | Sohye Lee Jongyeol Lee Seongjun Kim Yujin Roh Kamariah Abu Salim Woo-Kyun Lee Yowhan Son | 2018 | Journal of Forestry Research2018，29，1： | 2 |
