2012-01-13Effects of Plant Functional Group Removal on Microbial Substrate Metabolic Function and Soil Respiration in Subtropical Eucalyptus PlantationsSince aboveground communities and belowground communities are intimately linked and these linkages greatly affect ecosystem properties,removal of plant functional groups from aboveground communities will exert a great impact on belowground communities. Based on the previous works that found plant functional group removal greatly altered soil mic...

2011-11-08More Factors should be Considered in Prediction of Forestry Productivity Based on BiomassThe relationship between tree productivity and biomass not only re□□ects plant adaptation and the interaction of plants and the environment,but also has signi□□cant implications in global carbon cycling,climate change,and forest management. Age)and then both linear regression model and allometric equation(i. Power function)were applied to de... The relationship between tree productivity and biomass not only re？ects plant adaptation and the interaction of plants and the environment, but also has signi？cant implications in global carbon cycling, climate change, and forest management. However, how biotic factors (e.g. tree age, diameter at breast height [DBH], height) and abiotic factor...Read More

2011-10-18Increased Phosphorus Availability Mitigates the Inhibition of Nitrogen Deposition on CH4 Uptake in an Old-growth Tropical ForestMore and more studies indicate that,nitrogen deposition inhibites forest soil methane(CH4)uptake. MO Jiangming from ecosystem management group of South China Botanical Garden(SCBG).Recently,Dr. This work was guided by Prof. MO Jiangming from ecosystem management group of SCBG and Prof. This finding firstly revealed the effects of N/P interaction... More and more studies indicate that, nitrogen deposition inhibites forest soil methane (CH4) uptake. Consequently, nitrogen (N) deposition increases atmospheric CH4 concentration due to weaken the function of forest soil as CH4 sink. This standpoint has been supported by Dr. ZHANG Wei (Zhang et al., Journal of Geophysical Research-Atmospheres, 2...Read More
