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 Fitzinger in 1843. Later it was placed into the genus ''Hyla'', the true tree frogs, by Boulenger in 1882. Fouquette and Dubois 2014, treated ''Dryophytes'' as a subgenus of ''Hyla''. ''Dryophytes'' was finally resurrected as an independent genus by Duellman et al. in 2016. Only geographical, rather than morphological, differences separates ''Dryophytes'' from the genus ''Hyla''. ''Hyla'' is found only in the Old World, whereas ''Dryo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pine Barrens Tree Frog
The Pine Barrens tree frog (''Dryophytes andersonii'') is a species of New World tree frog. It is becoming rare due to habitat loss. Physical characteristics ''Dryophytes andersonii'', only about long, is one of the smaller species of tree frogs. Members of the species are predominantly green, with wide, dark stripes. They often have spotted, orange-gold markings on the hidden surfaces of their legs and tend to have large toe pads. 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. Habitat ''Dryophytes andersonii'' is most commonly found in brushy areas, often near peat bogs or shallow ponds. They usually inhabit areas carpeted with thick moss. Adults are terrestrial, but tend to reside near water sources. Unlike most frogs, they are tolerant of low pH level ...

Bird-voiced Tree Frog
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 ...

American Green Tree Frog
The American green tree frog (''Dryophytes cinereus'' or ''Hyla cinerea'') is a common 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. Commonly found in the central and southeastern United States, the frog lives in open canopy forests and permanent waters with abundant vegetation. When defending territory, the frog either emits aggressive call signals or grapples with intruders. To avoid predation, the frog hides in its aquatic habitat. Females are larger than males and breed through amplexus. In contrast, males emit low frequency advertisement calls to attract females. During mating competition, males will eavesdrop on neighboring rivals and either adjust their signal timing or remain silent to intercept call signals and mate with approaching females. Androgens energize males to vocalize. Description Many individuals of the American green tree frog are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cope's Gray Tree Frog
Cope's gray treefrog (''Dryophytes chrysoscelis'') is a species of treefrog found in the United States. 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.

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 and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species.

Bocourt's Tree Frog
Bocourt's tree frog (''Dryophytes bocourti''), or Bocourt's treefrog, is a species of frog in the family Hylidae endemic to Guatemala and found on the mountains of the southern Alta Verapaz Department and Baja Verapaz Department. It is named after Marie Firmin Bocourt, a French zoologist and artist. Bocourt's tree frogs have 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. They appear to tolerate some habitat disturbance. They breed in temporary pools. The species 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 salamandrivorans''.

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, Mexico (state), 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 animal, nocturnal and carnivore, carnivorous. They are typically found in semiarid, rocky habitats near a permanent water ... [...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'' *** '' Julianus'' *** ''Lysapsus'' †...

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 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. Tree frogs are usually tiny as their weight has to be carried by the branches and twigs in their habitats. While some reach 10 ...

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, ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
François Mocquard
François Mocquard (27 October 1834 – 19 March 1917) was a French herpetologist born in Leffond, Haute-Saône. In 1860 he was named ''préparateur du physique'' after receiving his Bachelor of Science degree at the Faculty of Besançon. Subsequently, he earned degrees in physical sciences (1862), mathematical sciences (1865) and medicine (1873). Despite being middle-aged, he made a career change, and began studying natural sciences in the laboratory of Alphonse Milne-Edwards (1835-1900) at the Muséum national d'histoire naturelle in Paris. In 1884 he earned his doctorate of sciences with a thesis on the structure of the stomach in crustaceans, afterwards working as an assistant in the ichthyology and herpetology department at the museum. During his career he described numerous herpetological taxa, most notably species from Madagascar, Tonkin, Borneo, Mexico and Central America. In addition, he has several species named after him, including reptiles, '' Alluaudina mocquardi'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
