Tree-Ring Chronologies, Assessments and Environmental Interactions in Undergraduate Laboratories

9451025卢肯树轮年表及相关活动被用来聚焦两个新开发的本科实验室。这些年表以岩心的形式，代表了有机体/环境相互作用的独特和容易获得的长期记录。一个生物学入门实验室要求学生测量一系列年轮、年轮宽度和气候因素之间的关系。还讲授了精确度、精确度和变量识别的概念。另一个生态学实验室要求学生测量一系列年轮，以确定影响一段时间内生长的气候因素的组合。

9451025 Luken Tree-ring chronologies and related activities are used to focus of two newly developed undergraduate laboratories. These chronologies, in the form of cores, represent unique and readily available long-term records of organism/environment interaction. One laboratory for introductory biology requires students to measure a series of tree-rings, relationships between ring-widths, and climatic factors. The concepts of accuracy, precision, and variable identification are also taught. Another laboratory in ecology requires students to measure a series of tree-rings to determine combinations of climatic factors that affect growth over periods of time.
