Research on the mechanisms of secondary plant succession is generally focused on mechanistic and stochastic processes determined by species characteristics and chance events. Variation not explained by these processes is often attributed to undefined historical factors. This research will focus explicitly on these historical factors as they have affected succession on the North Carolina Piedmont over the last two centuries. Past vegetation will be reconstructed using pollen analysis of sediment from old, undisturbed farm ponds and archival studies. Specific factors from these analyses will be related to succession through forest simulation models to predict their effects on patterns of succession. These patterns will then be compared with data from the Duke Forest. Such a study will improve our ability to understand and predict changes in forest composition. Dr. Russell will teach a joint botany/history department seminar on the history of human impact on the environment and a short course on the roles of women in botany and ecology. She will also present a guest lecture on recent vegetational history of the northeastern U.S., based on pollen analysis, and will give guest lectures in botany, history and the women's studies programs. This project furthers VPW program objectives which are (1) to provide opportunities for women to advance their careers in engineering and in the disciplines of science supported by NSF and (2) to encourage women to pursue careers in science and engineering by providing greater visibility for women scientists and engineers employed in industry, government, and academic institutions. By encouraging the participation of women in science, it is a valuable investment in the Nation's future scientific vitality.

植物次生演替机制的研究， 专注于由物种决定的机械和随机过程 特征和偶然事件。 无法解释的变化 这一过程往往归因于不确定的历史因素。 这 研究将明确集中在这些历史因素，因为他们 影响了北卡罗来纳州皮埃蒙特的继承 两个世纪 过去的植被将利用花粉重建 分析来自古老的、未受干扰的农场池塘和档案的沉积物 问题研究 这些分析的具体因素将与以下方面有关： 通过森林模拟模型预测其影响 继承的模式。 然后将这些模式与 来自杜克森林的数据。 这样的研究将提高我们的能力， 了解和预测森林组成的变化。 罗素博士将教授一个联合植物学/历史系研讨会上 人类对环境影响的历史和短期课程， 妇女在植物学和生态学中的作用。 她还将介绍一个 关于美国东北部最近植被历史的客座讲座， 基于花粉分析，并将在植物学方面进行客座演讲， 历史和妇女研究项目 该项目进一步促进了VPW计划的目标，即（1）提供 为妇女提供在工程和技术领域发展职业生涯的机会 由NSF支持的科学学科和（2）鼓励妇女 通过提供更大的科学和工程专业知识， 在工业界就业的女科学家和女工程师的知名度， 政府和学术机构。 通过鼓励 妇女参与科学，这是一项宝贵的投资， 国家未来的科学活力。
