Ice-Proximal Paleoclimates at the Wisconsin-Holocene Transition-Paleoentomology

昆虫化石是第四纪可靠、灵敏的指示物 环境，并且对于描绘间隔特别有价值 快速的气候变化。 在北美，许多研究 集中在威斯康星州全新世过渡在冰近端网站。 这项研究的目的是合成和量化化石 北美甲虫古气候重建，使用 相互气候范围（MCR）方法。 这是一种定量方法 分析昆虫化石数据， 化石组合中每个物种的气候范围。 MCR 分析将应用于所有已发表的近端冰晚期 威斯康星州昆虫记录在北美，并将用于 校正现有数据，以提供温度等压线图， 主要区域。 MCR结果将与 为欧洲动物群和北美 基于孢粉学的重建。

Insect fossils are reliable, sensitive indicators of Quaternary environments, and are especially valuable for delineating intervals of rapid climate change. In North America, many studies have focused on the Wisconsin-Holocene transition at ice-proximal sites. The aim of this research is to synthesize and quantify fossil beetle paleoclimate reconstructions for North America, using the Mutual Climate Range (MCR) method. This is a quantitative method of analyzing the insect fossil data by establishing the modern climate range for each species in a fossil assemblage. MCR analyses will be applied to all published ice-proximal late Wisconsin insect records in North America, and will be used to calibrate the existing data to provide temperature isobar maps for major regions. The MCR results will be compared with those established for European faunas and with North American reconstructions based on palynology.
