Chorus Frog
''Pseudacris'' (commonly known as the chorus frogs) is a genus of frogs in the family Hylidae found in North America ranging from the Pacific coastline to the Atlantic. The name of the genus comes from the Greek ''pseudes'' (false) and ''akris'' (locust), probably a reference to the repeated rasping trill of most chorus frogs, which is similar to that of the insect. It could also mean ‘false '' Acris''’, distinguishing it from another frog genus. Taxonomy The species in this genus are disputed. Molecular genetic research shows little consistency due to hybridization between species, making taxonomic organization difficult. The number of species in this genus is controversial, but Frost ''et al.'' list 19 species (all shown here), and AmphibiaWeb AmphibiaWeb is an American non-profit website that provides information about amphibians. It is run by a group of universities working with the California Academy of Sciences: San Francisco State University, the University of C ...

Pseudacris Ocularis
The little grass frog (''Pseudacris ocularis'') is a species of chorus frog Endemism, endemic to the Southeastern United States. It is currently the smallest North American anuran and occurs in a wide variety of ephemeral and semi-permanent wetlands. Description ''P. ocularis'' is the smallest frog in North America, only reaching a maximum head-body length of 19 mm (0.75 in). It is normally pale brown, but can have a green or pink tinge. This species is further characterized by a variable dark stripe which runs through each of the frog's eyes and down the sides of its body. The Latin term ''ocularis'' translates to "of the eye" in reference to this bold ocular stripe. Habitat & Feeding This species occurs in a wide variety of ephemeral and semi-permanent wetlands in the southeastern Coastal Plain and favors grassy areas in and around cypress ponds and similar sites. It is commonly found on lower tree trunks and foliage up to a height of 1 m or more; males prefer these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudacris Cadaverina
The California tree frog or California chorus frog (''Pseudacris cadaverina'') is a "true" tree frog (family Hylidae) from southern California (USA) and Baja California (Mexico). Until recently, the California tree frog was classified in the genus ''Hyla''. Description It is a cryptically colored species of tree frog, often resembling granitic stones. It is grey or light brown on its dorsum with darker blotches, and has a whitish venter. It is yellow on the undersides of its legs, groin, and lower abdomen; males of the species have a dusky-yellow throat. The California tree frog has conspicuous toe webbing and pads, and its dorsal skin is roughened and warty. It is long. Habitat and conservation This species is most likely to occur along streams with abundant boulders and cobbles in their channels. Its distribution is spotty and localized. These frogs are easily handled. California tree frog is not considered threatened by IUCN The International Union for Conservation of Na ...

Pseudacris Kalmi
''Pseudacris kalmi'', the New Jersey chorus frog, is a species of frog in the treefrog family Hylidae. It is found in the states near New Jersey in the United States. It was first described as subspecies of '' Pseudacris triseriata'' but it is differentiated by range and size.Conant, Roger and, Collins, John T., 1998, Peterson Field Guide: Reptiles and Amphibians, Eastern/Central North America, 616 pgs., Houghton Mifflin Company;, Boston This frog's color ranges from grey to tan or greenish brown with a dark stripe on both sides of the body that extends from the snout, through their eyes, and to the groin.

Pseudacris Illinoensis
The Illinois chorus frog (''Pseudacris illinoensis'') is a species of chorus frog that lives in scattered, restricted habitat ecosystems in the states of Arkansas, Illinois, and Missouri. It was published by Smith in 1951. Its life cycle is little known, its isolated populations are increasingly restricted by agricultural drainage, and it is listed as a threatened subspecies.Jeanne Townsend Handy, "The Secret Life of the Illinois Chorus Frog", ''Outdoor Illinois'' XIX:3 (March 2011), pages 9-11. It is often referred to as a subspecies of ''P. streckeri''. Collins recognized it as its own species which was followed by ASW6.0 and Amphibiaweb on the basis of its diagnosability from Pseudacris streckeri and its allopatry. The IUCNredlist 2013.2 has not incorporated this taxonomic split. Description The Illinois chorus frog, a wetland amphibian, grows to a maximum length of . Its range is restricted to isolated sandy wetlands along the banks of the Mississippi River and a major tribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudacris Feriarum
The upland chorus frog (''Pseudacris feriarum'') is a species of chorus frog found in the United States. It was recently separated from the Western chorus frog, (''Pseudacris triseriata''), being identified as an individual species rather than a subspecies. Habitat Within their range, this species is found in a variety of habitats that include: swampy areas of broad valleys, grassy swales, moist areas of woodlands and borders of heavily vegetated ponds. Description Upland chorus frogs are usually brown, grey-brown, or reddish-brown in color, with darker blotching. They grow from 0.75–1.5 inches (1.9–3.8 cm) in size.

Maximilian Zu Wied-Neuwied
Prince Alexander Philipp Maximilian zu Wied-Neuwied (23 September 1782 – 3 February 1867) was a German explorer, ethnologist and natural history, naturalist. He led a pioneering expedition to southeast Brazil between 1815–1817, from which the album ''Reise nach Brasilien,'' which first revealed to Europe real images of Brazilian Indians, was the ultimate result. It was translated into several languages and recognized as one of the greatest contributions to the knowledge of Brazil at the beginning of the nineteenth century. In 1832 he embarked on another expedition, this time to United States, together with the Swiss painter Karl Bodmer. Prince Maximilian collected many examples of ethnography, and many specimens of flora and fauna of the area, still preserved in museum collections, notably in the Lindenmuseum, Stuttgart. The genus ''Neuwiedia'' Carl Ludwig Blume, Blume (Orchidaceae) was named for him. Also, Prince Maximilian is honored in the scientific names of eight species ...

Pseudacris Crucifer
The spring peeper (''Pseudacris crucifer'') is a small chorus frog widespread throughout the eastern United States and Canada. They prefer permanent ponds due to their advantage in avoiding predation; however, they are very adaptable with respect to the habitat they can live in. Due to their presence in northern regions, the frog is able to endure below freezing temperatures. They are so called because of their chirping call that marks the beginning of spring. ''Crucifer'' is derived from the Latin root meaning "cross-bearing." This could be a reference to the cross-like pattern on the spring peeper's dorsal side. These chirping calls are significant for communication in mating as females choose their mates based on the frequency and volume associated with them. Satellite males who do not make any calls also strategically place themselves near those that make louder calls in an attempt to intercept females. Temperature plays a large role in when the spring peeper begins br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
