Description

Data for 37 species of plethodontid salamanders. Variables include snout to vent length (SVL) as species size, tail length, head length, snout to eye length, body width, forelimb length, and hind limb length, all measured in mm. A grouping variable is also included for functional guild size. The data set also includes a phylogenetic covariance matrix based on a Brownian model of evolution, to assist in generalized least squares (GLS) estimation.

Details

The covariance matrix was estimated with the vcv.phylo function of the R package, ape, based on the tree described in Adams and Collyer (2018).
