Morphometric analyses
Due to the current lack of data regarding pedipalp spine homology across
amblypygid species, here we set out to quantify geometric complexity
using non-landmark based morphometric methods. We thus use elliptical
Fourier analysis on binarised outlines of amblypygid pedipalps. All
methods of measuring 2D shape complexity were implemented using the R
package ‘Momocs’ (Bonhomme et al., 2014).
