This grant supports a study of vegetational and climatic history of southwest Alaska as part of ongoing studies of late-Quaternary environments of northwestern North America. Specifically, this study will: 1) describe the relationship of modern pollen to modern vegetation and climate of southwest Alaska, 2) collect and analyze fossil pollen from lake sites in order to describe the paleovegetational and paleoclimatic history of the region, and 3) combine these data with previous palynological data to enhance our present understanding of late-Quaternary climate and vegetation in northwestern North America.

这笔拨款支持对阿拉斯加西南部植被和气候历史的研究，作为正在进行的北美西北部晚第四纪环境研究的一部分。具体而言，本研究将：1)描述了阿拉斯加西南部现代植被和气候与现代花粉的关系；2)收集和分析了湖泊遗址的花粉化石，以描述该地区的古植被和古气候历史；3)将这些数据与以往的孢粉资料结合起来，以增强我们对北美西北部晚第四纪气候和植被的认识。
