Professor Graumlich will compare fossil pollen records with simulated vegetation histories at five sites in the northern midwestern United States. She will incorporate tree.ring analysis of appropriate species to improve existing climate models, simulate vegetation histories under different climatic assumptions, and compare the results with fossil pollen records. Graumlich's research addresses the question of whether climatic change or vegetation dynamics is the most important factor controlling late.Pleistocene vegetational change. Her work should help resolve that question. Her results will also improve our understanding of relationships between climate and vegetation generally, and will be applicable to questions regarding current changes in natural vegetation.

Graumlich教授将在美国北部的五个地点将化石花粉记录与模拟植被历史进行比较。 她将结合树。对适当物种的分析以改善现有的气候模型，模拟不同气候假设下的植被历史，并将结果与​​化石花粉记录进行比较。 Graumlich的研究解决了气候变化或植被动态是否是控制迟到的最重要因素。 她的工作应该有助于解决这个问题。 她的结果还将改善我们对气候与植被之间的关系的理解，并适用于有关自然植被当前变化的问题。
