Sarcohyla
''Sarcohyla'' is a genus of frogs in the family Hylidae. It is endemic to Mexico and is found in the montane parts of the country between Durango in the north and Guerrero in the south. These frogs typically occur in pristine habitats along streams in pine-oak woodland at elevations between above sea level. The generic name is derived from the Greek ''sarkodes'' meaning "fleshy" in combination with '' Hylas'' and refers to the thick, glandular skin characteristic of most of the species in the genus. Description ''Sarcohyla'' are moderate to large-sized frogs. They have thick, glandular skin. Osteological characteristics include enlarged prepollex without a projecting spine and the alary process of the premaxilla that is not bifurcate posteriorly. Taxonomy ''Sarcohyla'' was erected in 2016 based on molecular data. It contains species that were allocated to "'' Hyla bistincta''" and "'' Hyla arborescandens'' groups" by Duellman in 2001 and to "''Plectrohyla bistincta'' group" in ...

Sarcohyla Bistincta
''Sarcohyla bistincta'', also known as the Mexican fringe-limbed treefrog or Cope's streamside treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico; it is widespread and occurs from southern Sinaloa and Durango southeastward to Veracruz and Oaxaca. The nominal ''Sarcohyla bistincta'' consists of several lineages that may eventually be described as distinct species. Description Males grow to a snout–vent length of and females to . The head is wider than it is long; the snout is short and rounded. The tympanum is distinct but partly obscured by the supratympanic fold. The fingers are moderately long and slender and bear moderately large discs; only vestigial webbing is present. The toes are moderately long and slender too and bear discs that are slightly smaller than the finger ones. The toes are partially webbed. Skin is dorsally smooth but ventrally granular. Dorsal coloration varies from yellowish brown to dark brown (juveniles in some populations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcohyla Hapsa
''Sarcohyla hapsa'', the northern streamside tree frog, is a frog in the family Hylidae, endemic to Mexico. Range and habitat Scientists have seen it between 1,280 and 2,550 meters above sea level in the southern Sierra Madre Occidental from Durango to Nayarit states, the Trans-Mexican Volcanic Belt of Michoacán, Morelos, Guerrero, and Mexico states, and the northern Sierra Madre del Sur The Sierra Madre del Sur is a mountain range in southern Mexico, extending from southern Michoacán east through Guerrero, to the Isthmus of Tehuantepec in eastern Oaxaca.

Sarcohyla Crassa
''Sarcohyla crassa'' is a species of frog in the family Hylidae. It is endemic to the Sierra Madre de Oaxaca of Oaxaca, Mexico. It is also known as the aquatic treefrog, or when referring to the former ''Hyla bogertae'', Bogert's aquatic treefrog. ''Sarcohyla crassa'' occurs in streams in montane cloud forest at elevations of above sea level Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The comb .... It is threatened by the loss of original montane forests and possibly chytridiomycosis.

Sarcohyla Arborescandens
''Sarcohyla arborescandens'' is a species of frog in the family Hylidae. It is endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and rivers. This frog has been observed between 1800 and 3100 meters above sea level. This frog breeds in streams, and scientists have observed it in some streams in disturbed habitats, such as streams through cleared areas and roadside pools. Scientists believe human beings in central Veracruz probably consume these frogs as food. References Amphibians described in 1939 Taxonomy articles created by Polbot arborescandens {{Hylinae-stub ...

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'' †...

Endemic Amphibians Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of North America
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Thumb
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: # Any of the five terminal members of the hand. # Any of the four terminal members of the hand, other than the thumb Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness.
