Dryophytes
''Dryophytes'' is a genus of Ameroasian tree frogs in the family Hylidae. They are found mostly in North America, but the genus also includes three species found in eastern Asia. Description ''Dryophytes'' consists of small tree-dwelling frogs, usually green or gray in color. They have digits ending with expanded discs to help them sick to surfaces like trees. Habitat These tree frogs are found in wetlands throughout their range, as well as in temperate forests both on the ground and in trees. Taxonomy The genus was first described by Leopold Fitzinger, Fitzinger in 1843. Later it was placed into the genus ''Hyla'', the true tree frogs, by George Albert Boulenger, Boulenger in 1882. Martin J. Fouquette Jr, Fouquette and Alain Dubois, Dubois 2014, treated ''Dryophytes'' as a subgenus of ''Hyla''. ''Dryophytes'' was finally resurrected as an independent genus by William E. Duellman, Duellman et al. in 2016. Only geographical, rather than morphological, differences separates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine Barrens Treefrog
The Pine Barrens tree frog (''Dryophytes andersonii'') is a species of New World tree frog. It is becoming rare due to habitat loss. Description ''Dryophytes andersonii'' is about long, snout-to-vent, as an adult. Members of the species are predominantly emerald green. The green coloration is bordered by a white stripe, which separates it from a later plum band that extends downwards to cover the belly. The hidden surfaces of their legs are orange to yellow.Bunnell, John.The Pine Barrens Treefrog. New Jersey Pinelands Commission, 2012. Retrieved 9 January 2023. The belly is covered in white areolae. The toes are partially webbed, while the fingers are free. The pads of both fingers and toes are small. The key to distinguishing the Pine Barrens tree frog from the similar-appearing American green tree frog (''D. cinerea'') is the white-bordered lavender stripe on each side of the body in the Pine Barrens tree frog. ''D. cinerea'' has only a white stripe in this location. Habita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cope's Gray Treefrog
Cope's gray treefrog (''Dryophytes chrysoscelis'') is a species of treefrog found in the United States and Canada. It is almost indistinguishable from the gray treefrog ('' Dryophytes versicolor''), and shares much of its geographic range. Both species are variable in color, mottled gray to gray-green, resembling the bark of trees. These are treefrogs of woodland habitats, though they will sometimes travel into more open areas to reach a breeding pond. The only readily noticeable difference between the two species is the mating call — Cope's has a faster-paced and slightly higher-pitched call than ''D. versicolor''. In addition, ''D. chrysoscelis'' is reported to be slightly smaller, more arboreal, and more tolerant of dry conditions than ''D. versicolor''.Martof, B. S., et al. (1980). ''Amphibians and Reptiles of the Carolinas and Virginia''. Chapel Hill: University of North Carolina Press. . Taxonomy Edward Drinker Cope described the species in 1880. The specific name, ''chr ...

American Green Tree Frog
The American green tree frog (''Dryophytes cinereus'' or ''Hyla cinerea'') is a common Species, arboreal species of New World tree frog belonging to the family Hylidae. This nocturnal insectivore is moderately sized and has a bright green to reddish-brown coloration. Sometimes, light yellowish spots are present on the dorsum. Commonly found in the central and southeastern United States, the frog lives in open canopy forests with permanent water sources and abundant vegetation. The American green tree frog is strictly aquatic during the hibernating and mating seasons. When defending its territory, the frog either emits aggressive call signals or resolves to grapple with intruders, seldom leading to injury or death. To avoid predation, the frog will leap into the water or jump into the treetops. Female green tree frogs are larger than males. Body size is often a critical determinant of competitive ability and reproductive behavior. Pairs breed through amplexus. Males emit low freque ...

Bird-voiced Treefrog
The bird-voiced tree frog (''Dryophytes avivoca'') is a species of frog in the family Hylidae, endemic to the United States. Its natural habitats are temperate forests, shrub-dominated wetlands, and swamps. Description The bird-voiced tree frog is a small species growing to about long. It is usually a dappled, pale grey or brown on its dorsal surface, but its color changes with the temperature and its level of activity, and may be more or less pale green. It often has a dark brown cross-shaped mark on its back and further dark areas on its limbs. Its belly is grey with flashes of yellow on the underside of its hind legs. The male has a dark throat. This frog is very similar to the larger gray tree frog (''Dryophytes versicolor''), but that species has an orange flash on its hind legs. Both have a whitish square region just underneath the eyes. The bird-voiced tree frog is easily distinguishable during the spring and summer when it gives its characteristic call. Distribution and ...

Dryophytes Arboricola
''Dryophytes arboricola'', commonly known as the arboreal treefrog, is a species of frog in the family Hylidae endemic to the Sierra Madre del Sur in Guerrero state, Mexico. ''Dryophytes arboricola'' is a poorly known frog. It is assumed to be a montane forest species that breeds in temporary pools. It is probably impacted by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Bocourt's Tree Frog
Bocourt's tree frog (''Dryophytes bocourti)'', or Bocourt's treefrog, is a species of frog in the family Hylidae. The species is endemic to Guatemala and found on the mountains of southern Alta Verapaz Department and Baja Verapaz Department. It is named after Marie Firmin Bocourt, a French zoologist and artist. xiii + 244 pp. Habitat Bocourt's tree frog has been found in open, grassy meadows that are flooded during the early part of the rainy season, as well as under sheaths of banana plants and in a bromeliad. It appears to tolerate some habitat disturbance. Reproduction Bocourt's treefrog breeds in temporary pools. Conservation status The species ''Dryophytes bocourti'' seems to have undergone a serious decline. This is attributed to pesticide pollution from the ornamental plant industry and, possibly, to chytridiomycosis Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi '' Batrachochytrium dendrobatidis'' and '' Batrachochytrium s ...

Canyon Tree Frog
The canyon tree frog (''Dryophytes arenicolor'') is a species of tree frog native to the rocky plateau areas of southern United States, primarily in New Mexico and Arizona, but it also ranges to Utah, Texas, and Colorado, and as far south as the Mexican states of Michoacán, México, Guanajuato, Guerrero, and Oaxaca. Description Canyon tree frogs grow to in length, and are typically brown, grey-brown, or grey-green in color, often with darker-colored blotching. They can vary considerably, but usually match the soil or rock coloration of their native habitats to serve as camouflage. Those from limestone habitats are lighter colored, and those from regions composed mostly of granite can even be pink in coloration. Most have bright yellow in their groin regions, and faded banding on their legs. Behavior Canyon tree frogs are mostly nocturnal and carnivorous. They are typically found in semiarid, rocky habitats near a permanent water source. Breeding occurs during the spring ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as " tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** '' Boana'' – gladiator treefrogs *** '' Bokermannohyla'' *** '' Hyloscirtus'' *** '' Myersiohyla'' *** '' Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***'' Dendropsophus'' *** ''Xenohyla ** Tribe Hy ...

Hyla
''Hyla'' is a genus of frogs in the tree frog family Hylidae. As traditionally defined, it was a wastebasket genus with more than 300 species found in Europe, Asia, Africa, and across the Americas. After a major revision of the family, most of these have been moved to other genera so that ''Hyla'' now only contains 17 extant (living) species from Europe, northern Africa and Asia. The earliest known fossil member of this genus is †'' Hyla swanstoni'' from the Eocene of Saskatchewan, Canada, but its designation to ''Hyla'' happened before the major revision, meaning that its position needs confirmation. The genus was established by Josephus Nicolaus Laurenti in 1768. It was named after Hylas in Greek mythology, the companion of Hercules. The name is unusual in that – though Laurenti knew that Hylas was male – the name is unambiguously treated in the feminine grammatical gender for reasons unknown. The etymology of the name is also often incorrectly given as being derived fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Frog
A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia suborder have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related. Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. Description As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults, and '' Eleutherodactylus'' has evolved direct development and therefore does not need water for a tadpole stage.

Percy Viosca
Percy Viosca Jr. was a freshwater and marine biologist who specialized in the fauna of Louisiana and in the aquaculture of sportfish. He identified four species of native Louisiana iris and experimented extensively with iris breeding, much like his contemporary Caroline Dormon. He was awarded bachelor's and master's degrees in science at Tulane University, where he was also appointed lecturer. His early career included many scientific publications with taxonomic contributions and life histories of the animals he studied. Later, his interests shifted to methods of increasing the productivity of freshwater aquaculture. His reports on this subject often take examples from his work as a fisheries consultant and the biological supply company he operated. While working for the Louisiana Department of Wildlife and Fisheries in the field of herpetology, he documented the coastal Louisiana landscape. His work also included mosquito control, riparian and marshland studies, flood control, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
