Forest ecosystem diversity, function and service in response to perturbations: the key regulatory role of biogeochemical cycling

点击翻译按钮获取中文摘要

The natural and anthropogenic perturbations such as elevated atmospheric carbon dioxide (CO2), nitrogen(N) deposition, fires and land contamination have transformed much of the land surface on the earth and significantly modified terrestrial biogeochemical cycles in the past century. This project seeks to develop and apply novel nuclear magnetic resonance spectroscopy, isotopic and bio-molecular techniques to examine the key role of interactive biogeochemical cycles of carbon and major elements (N, Phosphorous) in regulating forest ecosystem responses to these perturbations. This project will result in improved mitigation and adaptation strategies for such perturbations, thereby restoring and sustaining forest ecosystems and conserving biodiversity in natural ecosystems.
