Within its native range, the Rio Grande Leopard Frog occurs in the lower Pecos River drainage of southeastern New Mexico, portions of Texas, and south through the eastern part of Chihuahua, Coahuila, Nuevo León, Tamaulipas, and the extreme eastern parts of San Luis Potosí, Querétaro, and Hidalgo. It occurs throughout the lowlands of Veracruz except for the southern portion of the state. It is distinguished from other Arizona leopard frogs by a combination of characters, including dorsolateral folds that are broken and inset towards the rear, a dark brown and tight reticulate pattern on the rear of the thigh, and usually no spots on the snout. Many of Arizona’s native frogs, particularly the five species of leopard frogs and the Tarahumara frog, might be considered “typical” stream-dwelling frogs; never being found too far from permanent water where they lay eggs, develop as tadpoles, and live as adult frogs.

The Lowland Leopard Frog, (Lithobates yavapaiensis), is a species of frog in the Ranidae family that is found in Mexico and the United States; in Spanish it is known as rana de Yavapai. BREEDING PHENOLOGY OF THE LOWLAND LEOPARD FROG (RANA YAVAPA1ENSIS): IMPLICATIONS FOR CONSERVATION AND ECOLOGY SHAWN S. SARTORIUS AND PHILIP C. ROSEN Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ 85721 Present address of SSS: Department of Zoology, University of Oklahoma, Norman, OK 73019 continue its range expansion to include streams inhabited by native lowland leopard frogs (R. yavapaiensis ), a species it closely resembles and is related to (Hillis 1988). The species is active both during the day as well at night. Lowland leopard frog is a species of frog found in Mexico and the United States. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater lakes, and freshwater marshes. disappearance of Lowland Leopard Frogs from several river basins (e.g., Colorado, Gila and Salt Rivers) correlates roughly with the estab lishment of Green Sunfish there (Clarkson and Rorabaugh, 1989; Rosen and Schwalbe, 2002; Sredl, 2005). Lowland Leopard Frogs (Rana yavapaiensis) have experienced extensive population declines over the last century. Ayer Lake, Boyce Thompson Arboretum, Pinal County, AZ 6 September, 2019 Note nictating membrane at 00:53 and frog trying to keep prey down starting at 00:57. In California, this species was historically known to occur in scattered localities in the extreme southeastern portion of the state, but it has not been positively documented since 1965. The leopard frog (Lithobates yavapaiensis) is a small (50 – 86 mm) frog in the ranid family Ranidae native Arizona, New Mexico, Nevada, California, and northern Sonora and Baja California, Mexico in the lower Colorado River basin. C O LO R AD O PARKS & WILD LIFE Leopard Frogs Species Description Identification Two leopard frogs are included in this guild: northern leopard frog (Rana pipiens) and plains leopard frog (R. blairi). Habitat Characteristics of Lowland Leopard Frogs in Mountain Canyons of Southeastern Arizona J ... nonnative animals, the geographic range of lowland leopard frogs in the United States has contracted, their populations have declined, and they no longer inhabit many of the valley-bottom environments where they were likely once most abundant (Arnold 1940, Pace 1974, Clarkson and … The lowland leopard frog is a relatively small leopard frog - maximum length is about 3.4 inches. A leopard frog (sometimes called a meadow frog) can mean any frog of about 14 species within the true frog genus Lithobates.They are generally similarly colored—green with prominent black spotting that sometimes appears as a leopard pattern.They are distinguished by their distribution and certain rather subtle ecological, behavioral, morphological and genetic traits. They are known to occur across a wide range of habitats and elevations (from 300 - 1,800 m) in streams, lakes, and stock ponds. We used data It is not considered threatened by the IUCN. Duration of water in these habitats ranges from semi-permanent to permanent. Although no study examining habitat use by adult lowland frogs has been conducted, lowland leopard frogs are found in a variety of natural and manmade aquatic systems within its range. They are roughly the same size (3–4 inches as adults), but plains leopard frogs are usually browner than the mostly green northern leopard frogs. comm.
