Description

Raw data inclusive of centroid size, shape coordinates, principal component scores for the skulls of n=36 canid taxa and bioclimatic variables for 13 canid guilds are in the "Meloro_Sansalone_GmmData.xlsx". The file "RPhyloCanid_36_shape.nts" is an R file suitable for the package geomorph that includes canid shape variables for 36 canid taxa. Phylogeny of the 36 taxa is in nexus format ("Canidae_36Guild_Extra.nex") and figured as pdf file ("Meloro_Sansalone_36Phylogeny_Description.pdf") while the file "13Guid_Average.NTS" includes the shape coordinates for the 13 canid guilds analysed.

Steps to reproduce

The data were produced applying geometric morphometrics protocol to a subset of 133 pictures of canid skulls in ventral view. The specimen used are listed in Supplementary Material of "Meloro, C., Hunter, J., Tomsett, L., Portela Miguez, R., Prevosti, F. J., & Brown, R. P. (2017). Evolutionary ecomorphology of the Falkland Islands wolf Dusicyon australis. Mammal Review, 47(2), 159-163". Each image was covered by 23 anatomical landmarks using the software tpsDig 2 (http://www.sbmorphometrics.org/soft-dataacq.html). The shape coordinates and centroid size data were first obtained using the software tpsRelw and then subsequently averaged in excel. The data were subsequently analysed using the package "geomorph" in R.
