Geometric Morphometric Methods for Functional Morphological Studies

近年来，人们捕捉和分析生物结构形状的方式发生了一场革命。人们现在可以把形状作为一个整体来分析，而不必把它分解成一组特别的变量，比如比率。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。还将开发软件来实施这些方法。具体而言，pi将调查以下主题。1)将方法推广到铰接结构的分析；2)开发识别地标共变子集的方法；3)开发软件，将形状差异表示为扭曲（变形）图像；4)在TPS系列软件中包含大纲信息；5)开发非对称分析软件；6)开发软件，将系统发育树与几何形态测量数据拟合，用于比较法研究。

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.
