资源简介:
These data are raw geometric morphometric landmark coordinates generated from photographs of carapaces of the Eastern Box Turtle (Terrapene carolina) in dorsal, lateral, and posterior views. Landmarks were generated in TPSDig and TPSDig2 (J. Rohlf, http://life.bio.sunysb.edu/ee/rohlf/software.html). The photographs used to digitize landmarks are included as a separate dataset within this project. <br><br>They were generated for the M.S. Thesis "The Eastern Box Turtle (Terrapene carolina) in space and time" and the manuscript "Delineating taxonomic boundaries and exploring range shifts within and between species in the fossil record using shell variation in the Eastern Box Turtle (<i>Terrapene carolina</i>)", both by N.S. Vitek. <br>In these TPS files, semilandmark curves have already been appended to landmarks and the resulting overlapping landmarks have already been deleted. Landmarks have not yet been superimposed and aligned in this file. Symmetrical views (dorsal, posterior) still contain both symmetrical halves. <br>For the aligned version of these landmarks that were used in the analysis, please see the dataset of aligned coordinates and metadata in this project.
