Philautus Abditus
''Philautus abditus'' is a species of frog in the family Rhacophoridae. It is found in the highlands of central Vietnam (Kon Tum and Gia Lai Provinces) as well as in extreme northeastern Cambodia ( Ratanakiri Province). The specific name ''abditus'' is Latin for "hidden" or "concealed" and refers to the black spots on the legs that are concealed while the legs are flexed. Description Adult males measure and adult females in snout–vent length. The overall appearance is stocky. The snout is rounded. The tympanum is present but completely hidden by skin; the supratympanic fold is weakly curved. The fingers and toes bear round discs; the toes are extensively webbed. Skin is smooth dorsally and laterally but granular ventrally. Preserved specimens are dorsally pinkish brown or gray. The anterior and the posterior surfaces of the thighs bear large, black spots that are not visible when the legs are flexed. Males have a median vocal sac.

Robert F
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and '' berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It c ...

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 combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Taxa Named By Robert F
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Described In 1999
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 ...

Philautus
''Philautus'' is a genus of shrub frogs in the family Rhacophoridae from Asia. Some species in this genus are now considered extinct by IUCN, while others are widespread and abundant (such as the recently described ''P. abundus'', which was specifically named for this fact). The taxonomy of the group is unclear, with many poorly described species. This genus is unique in that development not direct, with all growth inside the egg and no free-swimming tadpole stage. Some species have been found to bury their eggs in soil, although they are arboreal, and others attach their eggs to leaves. Revision In early 2009, Delhi University researchers revised this genus after discovering and rediscovering species in Western Ghats forest. List of species The following species are recognised in the genus ''Philautus'': * ''Philautus abditus'' Inger, Orlov, and Darevsky, 1999 * ''Philautus acutirostris'' (Peters, 1867) * ''Philautus acutus'' Dring, 1987 * ''Philautus amabilis'' Wostl, Riy ...

Virachey National Park
Virachey National Park ( km, ឧទ្យានជាតិវីរជ័យ) is a national park in north-eastern Cambodia covering an area of . The park is one of only two Cambodian ASEAN Heritage Parks. The park overlaps Ratanakiri and Stung Treng Provinces. The park's flora and fauna is threatened by illegal logging. Administration of the park is the responsibility of the Cambodian Ministry of Environment. Description Located in some of the most deep and isolated jungles of Cambodia, Virachey is largely unexplored and holds a large assortment of wildlife, waterfalls and mountains. The park comprises dense semi-evergreen lowlands, montane forests, upland savannah, bamboo thickets and occasional patches of mixed deciduous forest. Most of the area lies above 400 meters up to 1,500 meters. References Further reading *Baird, Ian G.

Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...

Ilya Darevsky
Ilya Sergeyevich Darevsky (russian: Илья Сергеевич Даревский, 18 December 1924 – 8 August 2009) was a Soviet Russian zoologist-herpetologist and a corresponding member of the Russian Academy of Sciences. During his career he described 34 species of amphibians and reptiles. '' Darevskia'', a genus of Caucasian rock lizards, is named after him. Early life and military career Darevsky was born on 18 December 1924 in Kiev. He was interested in amphibians and reptiles since his childhood, when he met Sergey A. Chernov, a herpetologist from Leningrad. During World War II, he was wounded twice and was decorated with the Order of the Red Star and Order of the Great Patriotic War of the 1st degree.Darevsky IS (2014My Biography ''Trudy Zoologicheskogo Instituta RAN''. 318(4): 292–325.
