Rohlf 9728160 In recent years, there has been a revolution in the way in which one is able to capture and analyze the shapes of biological structures. One can now analyze shape as a whole without having to break it down into sets of ad hoc variables such as ratios. This project is concerned with the further development of these morphometric methods - particularly for applications in functional morphology. Software will also be developed to implement the methods. Specifically, the PIs will investigate the following topics. 1) extend the methods to the analysis of articulated structures; 2) develop methods to identify covarying subsets of landmarks; 3) develop software to express shape differences as warped (deformed) images; 4) include outline information in the tps series of software; 5) develop software to analyze asymmetry; and 6) develop software to fit phylogenetic trees to geometric morphometric data for studies using the comparative method.

罗尔夫9728160 近年来，人们能够捕捉和分析生物结构形状的方式发生了革命。 现在，人们可以将形状作为一个整体进行分析，而不必将其分解为一组特定的变量，如比率。该项目关注这些形态测量方法的进一步发展-特别是在功能形态学中的应用。还将开发实施这些方法的软件。 具体来说私家侦探会调查 以下主题。 1)将这些方法扩展到关节结构的分析; 2）开发识别地标的共变子集的方法; 3）开发软件以将形状差异表示为翘曲（变形的）图像; 4）在TPS系列软件中包括轮廓信息; 5）开发软件来分析不对称性;以及6）开发软件以将系统发育树拟合到几何形态测量数据，用于使用比较方法的研究。
