Collaborative Research: Holocene Fire-Climate Linkages In Southern South America: Explaining Regional Responses To Large-scale Climate Forcing

为研究气候变率、火灾和生态系统之间的相互作用提供了资金。该项目的具体目标是更好地了解：(1)南美洲受夏季季风和西风带核心区域ENSO变率影响的火灾和植被历史；(2)火灾活动与植被变化在多时间尺度上的相互作用；(3)以古火重建和古气候模式模拟为代表的过去气候变化和气候变率。这项研究有望为环境变化及其与气候的关系提供数据和更广泛的理解。该项目将支持国际科学伙伴关系和培训机会，为美国和国外的研究生和本科生创造教育经验，并扩展最近创建的国际古火灾记录数据库，该数据库将满足科学界、自然资源管理者和政策制定者的需求。

Funding is provided to examine the interaction of climate variability, fire, and ecosystems. The specific objectives of this project are to gain a better understanding of: (1) fire and vegetation history in South America that is influenced by summer monsoons and ENSO variability at the core region of westerlies; (2) interactions among fire activity and vegetation change on multiple time scales; and (3) past climate change and climate variability as represented by paleo-fire reconstructions and paleoclimate model simulations.The research holds the promise of providing data and a broader understanding of environmental change and its relation to climate. The project will support international scientific partnerships and training opportunities, create education experiences for graduate and undergraduate students in the U.S. and abroad, and expand the recently created international database of paleo-fire records, which serves the needs of the scientific community, as well as natural resource managers and policy makers.
