ASM 2016 Geometric Morphometrics Workshop
iDigBio co-sponsored a full-day Geometric Morphometrics Workshop [1] with the American Society of Mammalogists (ASM) June 24, 2016, during the 96th Annual Meeting of ASM. The workshop was organized and convened by Kieran McNulty [2], Miriam Zelditch [3], and Don Swiderski.
During the morning of the workshop, Miriam gave a comprehensive lecture introducing geometric morphometrics. Topics covered during the lecture included: what is a landmark; how to collect landmark data; how to remove non-shape variation; how to analyze shape data (including Principal Components Analyses, Canonical Varieties Analysis, Procrustes Anova, and tree-based analyses); and how to display results for interpretation.
After the lecture, Don and Miriam gave demonstrations on both analytic and digitizing software. For two-dimensional data, they recommend a program called tpsDig [4], and for three-dimensional data, they recommend using Geomorph [5]. Participants were guided through several morphometric analyses exercises using several R packages provided before the workshop.
