Scutiger Boulengeri
''Scutiger boulengeri'' (common names: Boulenger's lazy toad, Boulenger's high altitude toad, Himalayan stream frog, and Xizang alpine toad) is a species of toad in the family Megophryidae. It is found in Nepal, India (Sikkim) and western China (Sichuan, Yunnan, Gansu, Qinghai, and Tibet). A healthy population has been found at an elevation of in one of the lakes in the Gurudongmar Lake complex in Sikkimese Himalaya. This is one of the highest elevations where amphibians have ever been recorded (''Pleurodema marmoratum'' has been recorded higher at the Andes). Description ''Scutiger boulengeri'' males measure about and females about in snout–vent length. The head is flat, wider than long and with a rounded snout. The eyes are protruding. The Tympanum (anatomy), tympanum is indistinct; the supratympanal fold is present. The Dorsum (anatomy), dorsum is olive or greenish-grey with numerous warts. The ventrum is yellowish.

Jacques Von Bedriaga
Jacques Vladimir von Bedriaga (last name sometimes spelled Bedryagha) (1854 - 1906) was a Russian herpetologist who was a native of Kriniz, a village near Voronezh. In scientific papers Bedriaga would sometimes alter his name to agree with the language of the country in which he was publishing. As a result, the following variations are encountered: Jacob Vladimirovich Bedriaga, Johann von Bedriaga, and Jean de Bedriaga. Biography He studied sciences at Moscow University under the direction of Anatoli Bogdanov (1834-1896), and afterwards moved to Germany, where he studied at the University of Jena with Ernst Haeckel (1834-1919) and Carl Gegenbaur (1826-1903). In 1875, he obtained his doctorate with a thesis on the urogenital organs of reptiles. After graduation, Bedriaga continued his research on reptiles with Gegenbaur, and made frequent scientific trips to regions around the Mediterranean. In 1880 he published an important work on Greek herpetology called ''Die Amphibien und R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of Tibet
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scutiger (toad)
''Scutiger'' is a genus of toads in the family Megophryidae. Common name lazy toads has been coined for them. They occur in China, Burma, Nepal, and northern India in high-altitude habitats. Most are endemic to China. Evolution A 2017 molecular phylogenetic study found that ''Scutiger'' originated in Paleo-Tibet during the Oligocene.

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

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 ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...
