Climate change and economic pressure to intensively harvest forests for biofuel production are both creating grave new challenges to sustainable forest management. Soil carbon cycling processes are vital to forest ecosystems and mediate the long-term effects of climate change and removal of biomass through harvesting. These processes are performed by extremely complex forest soil microbial communities comprised of thousands of species of fungi and bacteria, most of which cannot be cultivated in the laboratory. In field studies, we will investigate how these processes are affected by forest management options and landscape changes due to climate change. In particular, we will focus on the transfer of carbon between trees via

气候变化和为生产生物燃料而大量砍伐森林的经济压力都对可持续森林管理造成了新的严重挑战。土壤碳循环过程对森林生态系统至关重要，并介导气候变化的长期影响和通过采伐减少生物量。 这些过程是由极其复杂的森林土壤微生物群落进行的，这些微生物群落由数千种真菌和细菌组成，其中大多数无法在实验室中培养。在实地研究中，我们将调查这些过程如何受到森林管理方案和气候变化引起的景观变化的影响。特别是，我们将重点关注树木之间的碳转移，
