Comment

Reviewed by Karlstrom, 1973, Cat. Am. Amph. Rept., 132: 1–2. In the Bufo boreas group of Blair, 1972, Evol. Genus Bufo: 350. Shaffer, Fellers, Magee, and Voss, 2000, Mol. Ecol., 9: 245–257, reported on molecular geographic variation. Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 210-211, provided a brief account, figure, and map. Davidson and Fellers, 2005, in Lannoo (ed.), Amph. Declines: 400–401, provided a detailed account, map, and conservation status. See photograph, map, description of geographic range and habitat, and conservation status (as Bufo canorus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 180, who noted that Anaxyrus exsul may be conspecific with this species. Goebel, Ranker, Corn, and Olmstead, 2009, Mol. Phylogenet. Evol., 50: 209–225, found the mtDNA haplotypes of Anayxrus canorus to form a polyphyletic group, with the name-bearing clade being imbedded within a clade of Anaxyrus boreas including most of that species' range and another clade related to a clade of Anaxyrus boreas centered on it's southwestern component of range. Dodd, 2013, Frogs U.S. and Canada, 1: 70–77, provided an account that summarized relevant literature. Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 182–183, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 177–178, provided an account of larval morphology and biology. Maier, Vandergast, Ostoja, Aguilar, and Bohonak, 2019, Evolution, 73: 2476–2496, discussed Pleistocene molecular phylogeography.
