Ecosystem and biogeochemical reassembly after fire on peatlands

该项目将发生在苏格兰北部，那里的野火烧毁了跨越各种生态环境的地区，而且这些地块的火灾历史不同。对植物生物量和土壤有机质的采样将用于量化生态系统中的总碳储量。碳循环的变化将通过监测植物生长，结合使用微生物活动的现场测量和特定微生物酶的实验室测量对土壤碳循环的分析来评估。将使用有机质化学、木炭含量和微生物群落的测量来确定控制碳周转的机制。

The project will take place in northern Scotland where wildfires have burned areas spanning a variety of ecological contexts and the plots differ in their fire history. Sampling of plant biomass and soil organic matter will be used to quantify the total stocks of carbon in the ecosystem. Changes incarbon cycling will be evaluated by monitoring plant growth combined with analyses of soil carbon cycling using in situ measures of microbial activity and laboratory measurements of specific microbial enzymes. Measurements of organic matter chemistry, charcoal content, and microbial communities will be used to determine the mechanisms controlling the carbon turnover.
