Soil respiration (RS) and soil carbon stocks, as well as stand properties were investigated in a warm-temperate oak chronosequence in order to understand the age effect on soil CO2 efflux. The chronosequence consisted of three 40-year-old, 48-year-old, 80-year-old, and 143-year-old oak stands, respectively. RS measurements were conducted using a Li-8100(More)
Multidrug resistance (MDR), mediated by overexpression of drug efflux transporters such as P-glycoprotein (P-gp), is a major problem limiting successful chemotherapy of gastric cancer. Tamoxifen (TAM), a triphenylethylene nonsteroidal antiestrogen agent, shows broad-spectrum antitumor properties. Emerging studies demonstrated that TAM could significantly(More)
A range of factors has been identified that affect the temperature sensitivity (Q₁₀ values) of the soil-to-atmosphere CO₂ flux. However, the factors influencing the spatial distribution of Q₁₀ values within warm temperate forests are poorly understood. In this study, we examined the spatial variation of Q₁₀ values and its controlling factors in both a(More)
The wetlands on the Qinghai-Tibet Plateau are experiencing serious degradation, with more than 90,000 hectares of marshland converted to wet meadow or meadow after 40 years of drainage. However, little is known about the effects of wetland conversion on soil C stocks and the quality of soil organic carbon (SOC) (defined by the proportion of labile versus(More)
Among the methods of measuring forest soil respiration, infrared CO2 analysis is the optimal one so far. Comparing with empirical model, the process-based model in simulating the production and transportation of soil CO2 has the advantage of considering the biological and physical processes of soil respiration. Generally, soil respiration is positively(More)
Plant biomass and its allocation patterns are instrumental in understanding global carbon sinks; however, knowledge is still limited, especially in high-altitude peatlands. We investigated aboveground and belowground biomass allocation in the Zoige peatland of the Tibetan plateau, China, and its relationship with environmental factors using data collected(More)
Liana constitutes an important structural and functional component in many forest ecosystems and has profound impacts on forest carbon (C) cycling. However, whether and how liana regulates spatial distributions of litterfall and soil organic C are still poorly understood. To address this critical knowledge gap, we investigated litterfall composition and(More)
