Dissertation Research: 3D Rotational Fit Analysis Using Turtle Shells

形状的翻译或转换成定量术语，以便不同的形状可以比较和解释是一个深刻的问题在系统生物学。这项研究将提供关于拟合技术的应用的信息，这些信息将对生物学许多领域的研究人员有用，并对那些对海龟的生态和进化问题感兴趣的人提供重要的形状变化的性质。拟议的研究有两个主要目标。首先是比较现有的和新开发的旋转拟合方法，使用一组来自生物材料的三维地标位置。这些数据将包括黄腹龟甲壳上生物和几何上定义的地标的坐标位置。我的剧本，剧本。第二个目标是利用这些数据来研究该亚种内由两性二态性、栖息地相关的生长差异和地理变异引起的形状差异。

The translation or conversion of shape into quantitative terms so that different shapes can be compared and interpreted is a profound problem in Systematic Biology. The research will provide information on the application of the fitting techniques that will be of use to researchers in many areas of biology and on the nature of shape variation of importance to those interested in ecological and evolutionary questions concerning turtles. The proposed research has two main goals. The first is to compare existing and newly developed rotational fitting methods using a set of three- dimensional landmark locations from biological material. The data will consist of the coordinate locations of biologically and geometrically defined landmarks on the carapace of the yellow- bellied turtle. Trachemys scripta scripta. The second goal is to use this data to investigate shape differences resulting from sexual dimorphism, habitat-related growth differences, and geographic variation within this subspecies.
