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.

摘要Propopal：合作研究：北极植物的冷季气交换 - 阿拉斯加北极苔原的冬季碳和水平衡。冬季，北极苔原植被的生理过程。这项研究将在寒冷的季节增加我们对北极苔原植被生理过程的理解，并提高我们对这些过程如何促进碳循环和气候变化的了解。该项目将研究寒冷的季节植物生理学，降雪下的碳获取，碳转换，寒冷季节的植物水源，死亡率和呼吸率对预测温度变化的敏感性。预计该结果将在寒冷季节对两个苔原生态系统的植物生理学和碳动态提供新的见解。
