Collaborative Research: Cold season gas exchange of arctic plants - resolving winter carbon and water balances of Alaskan arctic tundra

摘要提案：合作研究：北极植物冷季气体交换——解决阿拉斯加北极冻土带冬季碳水平衡问题。当前位置来自德克萨斯大学阿灵顿分校和佛罗里达国际大学的研究人员已获得资金，用于研究北极苔原植被在冬季的生理过程。这项研究将增加我们对寒冷季节北极苔原植被在雪下的生理过程的理解，并增加我们对这些过程如何促进碳循环和气候变化的认识。该项目将调查寒冷季节植物生理、积雪下的碳获取、碳周转、寒冷季节植物的水源、死亡率和呼吸速率对预测温度变化的敏感性。这一结果有望为研究两个冻土带生态系统在寒冷季节的植物生理和碳动态提供新的见解。

AbstractProposal: Collaborative Research: Cold-season gas exchange of arctic plants - resolving winter carbon and water balances of Alaskan arctic tundraP.I.:Gregory Starr Behzad MortazaviUniversity of Alabama TuscaloosaSteven F OberbauerFlorida International UniversityProposal # 0806776 Investigators from the University of Texas Arlington and Florida International University have received funding to investigate physiological processes of arctic tundra vegetation during the winter. The study will increase our understanding of physiological processes of arctic tundra vegetation under snow during the cold season and increase our knowledge of how these processes contribute to the carbon cycling and climate change. The project will investigate cold season plant physiology, carbon acquisition under snow, carbon turnover, sources of water for the plants during the cold season, mortality, and respiration rate sensitivity to predicted changes in temperature. The results are expected to provide new insights into plant physiology and carbon dynamics of two tundra ecosystems during the cold season.
