ABSTRACT PROPOSAL # : DEB-9806440 INVESTIGATOR(S) : TURNER INSTITUTION: UNIVERSITY OF WISCONSIN The 1998 Yellowstone fires affected over 250,000 ha, creating a mosaic of burn severity over the landscape that may influence ecosystem processes for decades or centuries to come. This study will develop quantitive predictions of postfire successional pathways and their consequences for ecosystem function across the Yellowstone landscape. The principal methods to be used are mapping and monitoring of permanent plots, combined with sophisticated spatial analysis and measurements of leaf area and net primary productivity. The focus is on variability within and among the major ecosystems of the Yellowstone landscape, and on variability in their responses to a large, common disturbance. The study will also contribute to understanding of potential effects of different fire regimes resulting from either management or climate change.

摘要建议＃：DEB-9806440调查员：特纳机构：威斯康星大学1998年的黄石大火影响了25万公顷，造成了景观的燃烧严重程度，这可能会影响数十年或几个世纪以来的生态系统过程。 这项研究将开发后火后期途径的定量预测及其对整个黄石景观生态系统功能的后果。要使用的主要方法是对永久地块的映射和监视，并结合复杂的空间分析以及叶片面积和净初级生产力的测量。 重点是黄石景观的主要生态系统内部和之间的可变性，以及它们对大型，常见干扰的响应的可变性。 该研究还将有助于理解管理或气候变化导致的不同火灾制度的潜在影响。
