Latest Rana Stories
While some scientists must travel to far-off exotic locations to discover new species, one team of American researchers found a new species in a much less desolate location – New York City.
Native species living along the Yellowstone River in Montana are being threatened by a growing invasion of voracious American bullfrogs known to eat just about anything (including other bullfrogs).
Recently, Malaysian herpetologist Juliana Senawi puzzled over an unfamiliar orange-striped, yellow-speckled frog she’d live-caught in swampland on the Malay Peninsula.
This frog species, which once hopped throughout California’s upper elevations, has dropped significantly in numbers, more than ninety percent in the past decade, due in part to chytrid, a skin
A 10-year study shows some good news for frogs and toads on national wildlife refuges.
Physically speaking, bullfrogs should be able to cover more distance in a single hop then they often do. Scientists have observed these amphibians clearing about four feet per jump, but rarely more than this, while other frog species can travel at more than seven feet per hop.
A two-year study from Oregon State and the University of Pittsburgh reveals bullfrogs are not only tolerant carriers that spread chytrid fungus, as previously thought. The bullfrogs are also dying from the pathogen.
Do frogs live underground? The answer is yes, some amphibians, such as salamanders and frogs have been often reported to dwell in subterranean habitats, some of them completely adjusted to the life in darkness, and others just spending a phase of their lifecycle in an underground shelter.
American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems.
New York City has many mysteries, however this latest has scientists scratching their heads. How did an entire species of frog - in one of the nation’s most crowded and oldest cities - go undiscovered for as long as it did?
The Wood Frog (Rana sylvatica) has a broad distribution over North America, stretching from the southern Appalachians to the boreal forest with several notable disjunct populations including lowland eastern North Carolina. This frog has garnered attention by biologist over the last century due to its freeze tolerance, relatively great degree of terrestrialism, interesting habitat associations, and relatively long-range movements. The wood frog is the state amphibian of New York. Similar to...
The Common Frog (Rana temporaria), known also as the European Common Frog or the European Common Brown Frog, is located throughout much of Europe as far north as well north of the Arctic Circle in Scandinavia and as far east as the Urals, except for the majority of Iberia, southern Italy, and the southern Balkans. The farthest west it can be found is Ireland, where it has long been considered erroneously to be an entirely introduced species. These frogs measure about 2.4 to 3.5 inches and...
The Mountain Yellow-Legged Frog (Rana muscosa) is a true frog native to California. They can be found in mountain creeks and lakes, meadow streams, isolated pools, and lake borders. They are usually found near steep-gradient streams of a chaparral belt or other water sources around 1,200 to 7,750 feet above sea level. The Southern Mountain Yellow-legged Frog is endangered and the Sierra Mountain Yellow-legged Frog is threatened. This is a small frog, measuring about 5 to 7.5 centimeters....
The Tarahumara Frog (Rana tarahumarae) is a species of frog belonging to the Ranidae family located in Mexico and the United States. Its natural habitats include temperate forests, rivers, and intermittent rivers. As with most ranid tadpoles, the larvae are most likely omnivorous with a strong tendency towards algivory. This species lives in streams and plunge pools in canyons located within oak and pine-oak woodland, and the Pacific coast tropical area. It’s threatened by loss...
The Pickerel Frog (Rana palustris) is a North American frog of small size, characterized by the appearance of seemingly “hand-drawn” squares on its dorsal surface. These rectangular spots of the pickerel frog may blend together to create a long rectangle along the back. All Leopard Frogs have circular shaped spots. Additionally, pickerel frogs have prominent dorsolateral ridges that are unbroken. Another significant distinguishing mark is the orange or yellow flash pattern found on the...
