Geometric Morphometrics is the analysis of shape using Cartesian geometric coordinates rather than linear, areal, or volumetric variables. Geometric morphometric methods (GMM) include 2D and 3D points representing landmarks, curves, outlines, or surfaces. This course is a practical, applied introduction to GMM. Students learn to collect, analyze, and interpret geometric morphometric data. Shape theory and methods are covered, including Procrustes superimposition and its statistical implications, analysis of curves and outlines, and Monte Carlo modeling of shape.
[Course Syllabus 2014]
Overview of principles of geometric morphometric methods (GMM), including definitions of landmarks, outlines and surfaces, differentiation between traditional morphometrics and GMM, short history of morphometrics, components of a morphometric study, and examples of equipment needed for GMM studies.
Learn basics of Mathematica, including basic operations, using cells and styles, writing short programs, defining functions, and making simple graphs.
