Yosemite Toad
Anaxyrus canorus (Camp, 1916)

Current SSAR Comments:
Multiple studies (e.g., Goebel et al., 2009, Molecular Phylogenetics and Evolution 50: 209–225, and Gordon et al., 2017, Zootaxa 4290: 123–139) have found two phylogenetically distinct mitochondrial DNA clades of this species, corresponding to samples from the southern Sierra Nevada range and northern samples from the same range. Goebel et al. (op. cit.) also reported hybrids between A. boreas and A. canorus. See comments under A. boreas; these issues require more research that is expanded to include nuclear DNA.

Range maps are based on curated specimens and provided gratis by CNAH.
