Principal Component Analysis and Isolation by Distance of Hypsiscopus murphyi and Hypsiscopus plumbea

Data and scripts for PCA and IBD of Hypsiscopus murphyi (description paper)

Taxon Sampling

• A complete list of all specimens included in this study can be found at:

Quantitative Morphological Analysis

• Principal Component Analyses were performed with a size standardized and unstandardized dataset seperately. All scripts and associated data files can be found at:

Isolation by Distance (IBD)

• Testing for IBD was performed with a Mantel Test. There are better methods to choose than this test, but are not investigated in this paper. The code and georeference data can be found at:
