9317572 Rohlf The field of morphometrics is concerned with methods for capturing information on the size and shape of biological structures and the analysis of shape change and shape variation in populations. Geometric morphometrics is a relatively new approach that takes into account the geometrical relationships among the features (positions of the landmarks and shapes of outlines, etcetera) rather than just measured distances or angles. The proposed research is concerned with the development, evaluation and application of new statistical and visualization methods for geometric morphometrics. The methods used will be applied to several datasets. these will include: two-dimensional data on the wings of mosquitoes, 3-dimensional data on yellow-bellied slider and painted turtles, and data from others. A large number of artificial datasets will be generated for the simulations that will be used to test the robustness and stability of the methods.

小行星9317572 形态计量学的领域涉及捕获生物结构的大小和形状信息的方法，以及种群中形状变化和形状变异的分析。 几何形态测量是一种相对较新的方法，它考虑了特征之间的几何关系（地标的位置和轮廓的形状等），而不仅仅是测量的距离或角度。 拟议的研究是关于几何形态计量学的新的统计和可视化方法的开发，评估和应用。 所使用的方法将适用于几个数据集。 这些措施包括：蚊子翅膀的二维数据，黄腹滑龟和彩绘龟的三维数据，以及其他数据。 将为模拟生成大量人工数据集，用于测试方法的鲁棒性和稳定性。
