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.

ROHLF 9728160近年来，人们已经有一场革命，可以捕获和分析生物结构的形状。 现在，人们可以整体分析形状，而不必将其分解为诸如比率之类的临时变量集。该项目与这些形态学方法的进一步发展有关，尤其是在功能形态中的应用。还将开发软件以实现方法。 具体而言，PI将研究以下主题。 1）将方法扩展到铰接结构的分析； 2）开发方法来识别相协方差的地标子集； 3）开发软件以表达形状差异为扭曲（变形）图像； 4）在TPS系列软件系列中包括大纲信息； 5）开发软件以分析不对称性； 6）开发软件，以使用比较方法将系统发育树适合用于研究的几何形态数据。
