''Anaxyrus'' is a genus of true toads in the family Bufonidae. The genus is endemic to North and Central America. Some authors consider ''Anaxyrus'' to be a subgenus within ''Bufo ''Bufo'' is a genus of true toads in the amphibian family Bufonidae.

Woodhouse's Toad
Woodhouse's toad (''Anaxyrus woodhousii'') is a medium-sized () true toad native to the United States and Mexico. There are three recognized subspecies. ''A. woodhousii'' tends to hybridize with '' Anaxyrus americanus'' where their ranges overlap. Taxonomy Woodhouse's toad was first described in 1854 by the French herpetologist Charles Frédéric Girard. He gave it the name ''Bufo woodhousii'' in honor of the American physician and naturalist Samuel Washington Woodhouse. The large genus ''Bufo'' was split by Frost ''et al.'' in 2006, with the North American species being included in the genus ''Anaxyrus'' and this toad becoming ''A. woodhousii''. There are three recognised subspecies: *Rocky Mountain toad – '' Anaxyrus woodhousii woodhousii'' ( Girard, 1854) *East Texas toad – ''Anaxyrus woodhousii velatus'' (Bragg and Sanders, 1951)Bragg, A. N., and O. Sanders. 1951. A new subspecies of the ''Bufo woodhousii'' group of toads (Salientia: Bufonidae). Wasmann Journal of Biol ...

Yosemite Toad
The Yosemite toad (''Anaxyrus canorus'', formerly ''Bufo canorus'') is a species of true toad in the family Bufonidae. Endemic to the Sierra Nevada of California, the species ranges from the Alpine County to Fresno County. Yosemite toads are only found in the montane to subalpine elevational zone of asl. The Yosemite toad is similar to the nearby Western toad, but in many ways adapted to a high elevation lifestyle. It was initially described during the Grinnell Survey of California, by an undergraduate student of Joseph Grinnell named Charles Camp. Description Adults Yosemite toads are medium-sized (48–84 mm SVL) stocky toads, with females averaging larger than males. They generally lack cranial crests, but males will rarely have weakly developed ones. Their eyes have a dark brown iris with gold iridophores. In comparison with the closely related Western toad (''A. boreas''), the parotoid glands are large, narrowly spaced, and irregularly shaped (oval or flattened) ...

Arroyo Toad
The arroyo toad (''Anaxyrus californicus'') is a species of true toads in the family Bufonidae, endemic to California (U.S.) and Baja California state (México). It is currently classified as an Endangered species on the IUCN Red List of Threatened Species because of habitat destruction. Description The arroyo toad is a stocky, blunt-nosed, warty-skinned species of toad, long. It has horizontal pupils, and is greenish, grey or salmon on the dorsum with a light-colored stripe across the head and eyelids. It has light sacral and mid-dorsal patches, large, oval and widely separated parotoid glands, and weak or absent cranial crests. The juvenile of this species are ashy-white, olive or salmon on the dorsal side, with or without black spotting. It has red-tipped tubercles on its back. Distribution and habitat ''Anaxyrus californicus'' prefers sandy or cobbly washes with swift currents and associated upland and riparian habitats, in Southern California from Santa Barbara County sou ...

Charles Lewis Camp
Charles Lewis Camp (March 12, 1893 Jamestown, North Dakota – August 14, 1975 San Jose, California) was a palaeontologist and zoologist, working from the University of California, Berkeley. He took part in excavations at the 'Placerias Quarry', in 1930 and the forty ''Shonisaurus'' skeleton discoveries of the 1960s, in what is now the Berlin-Ichthyosaur State Park. Camp served as the third director of the University of California Museum of Paleontology from 1930 to 1949, and coincidentally as chair of the UC Berkeley Paleontology Department between 1939 and 1949. Camp named a number of species of marine reptiles such as ''Shonisaurus'' and ''Plotosaurus'', as well as the dinosaur '' Segisaurus''. Camp was also an important bibliographer and historian of Western America. This aspect of his career is represented most notably by two works. The first is his biography of American pioneer James Clyman, which Bernard De Voto called "one of the half-dozen classics in the field." The secon ...

Western Toad
The western toad (''Anaxyrus boreas'') is a large toad species, between long, native to western North America. ''A. boreas'' is frequently encountered during the wet season on roads, or near water at other times. It can jump a considerable distance for a toad. Breeding occurs between March and July in mountainous areas, and as early as January in lower-elevation regions. The female lays up to 17,000 eggs stuck together in strings that adhere to vegetation and other objects along water edges. Description It has a white or cream dorsal stripe, and is dusky gray or greenish dorsally with skin glands concentrated within the dark blotches. Its parotoid glands are oval, widely separated, and larger than the upper eyelids. It has a mottled venter and horizontal pupils but lacks cranial crests. Compared to females, males have smoother skin, reduced dorsal blotching, and nuptial pads (thickened skin) on their forefeet during breeding season. In juveniles of this species, the dorsal stripe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
