The cycling of soil carbon (C) is a fundamental characteristic that defines the functioning of any ecosystem. My research program deals with assessing the factors and mechanisms controlling the cycling of soil C. This allows us to study a diversity of ecological and environmental situations such as greenhouse gas emissions, over-browsing by herbivores, and the ability of ecosystems to resist environment stress, to name but a few. The methodological approach we most frequently use are soil respirometry measurements of various kinds. This requires an instrument referred to as a Gas Chromatograph (GC). This grant proposal is intended to replace a 10-y-old GC that has become the centerpiece of our lab, but is currently broken and irreparable.

土壤碳(C)的循环是定义任何生态系统功能的基本特征。我的研究项目涉及评估控制土壤c循环的因素和机制，这使我们能够研究各种生态和环境状况，如温室气体排放，食草动物的过度浏览，生态系统抵抗环境压力的能力，等等。我们最常用的方法是各种土壤呼吸测量法。这需要一种称为气相色谱仪（GC）的仪器。这项拨款提案旨在取代一个10年的旧GC，它已经成为我们实验室的核心，但目前已经损坏且无法修复。
