Table S3.1. Habitat use of sampled snakes. Taxonomic nomenclature follows the current classification indexed in the Reptile Database ( http://www.reptile-database.org/ ). For some species, references may reflect outdated taxonomic status. Individual species are coded for habitat association according to Table 3.1. References for this table are listed below. Habitat use for species without a reference were inferred from sister taxa.
