Temperature sensitivity of soil respiration and its components

该项目旨在展示温带万年青森林如何缓冲气候变化。土壤呼吸将森林吸收的约一半碳返回大气。该项目将分析和量化土壤中的微生物和根系如何依赖于温度和基质供应，从而预测随着自然碳固存的下沉，气温上升和干旱将如何影响森林。该项目将解决森林土壤呼吸的环境驱动因素的作用;在一个共同的建模框架内整合对不同植物和微生物对温度反应的机械理解;并评估这一知识在预测气候对陆地碳循环影响方面的影响。

This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will resolve the roles of environmental drivers of soil respiration across forests; integrate mechanistic understanding of differing plant and microbial responses to temperature within a common modelling framework; and evaluate the implications of this knowledge in predictions of climatic impacts on terrestrial carbon cycling.
