Pewzow's Toad
''Bufotes pewzowi'' is a species of toad in the family Bufonidae. It is found in dry plains of Central Asia, the foothills and mountains of Tian Shan, Zhungar Alatau and Pamir Mountains (Kazakhstan, Kyrgyzstan, Uzbekistan, and Tajikistan), the mountains and deserts of Western China and Mongolia, and probably westward to northern Afghanistan and north to Lake Balkhash in Kazakhstan and northeast Altai Republic in Russia. The specific name ''pewzowi'' honours , a Russian geographer, cartographer, and explorer. Common names include Xinjiang toad and Pewzow's toad; when subspecies ''B. p. strauchi'' is recognized, it can be referred to as northern Xinjiang toad, while the nominotypic ''B. p. pewzowi'' then becomes southern Xinjiang toad. Description ''Bufotes pewzowi'' is a tetraploid species that originates from hybridization between ''Bufotes latastii'' and '' Bufotes perrini''. Adult males measure and adult females in snout–vent length. Gosner stage 35–37 tadpoles mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of Tajikistan
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Russia
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 ...

Bufotes
''Bufotes'', the Eurasian green toads or Palearctic green toads, is a genus of true toads (family Bufonidae). They are native to Europe (absent from the British Isles, most of Fennoscandia, most of France and the Iberian Peninsula), western and central Asia and northern Africa; a region roughly equalling the western and central Palearctic. Historically they were included in the genus ''Bufo'' and then for a few years placed in ''Pseudepidalea'', which is a synonym of the currently accepted name ''Bufotes''. ''Bufotes'' are typical toads and as suggested by their common names most—but not all— species and individuals have a distinct greenish-spotted pattern. They occur in a wide range of habitats and mostly lay their eggs in fresh water, but sometimes in waters that are brackish. Appearance Size and morphology ''Bufotes'' are fairly small to medium-large toads with adults that are between about in snout–to–vent length. The average size varies significantly depending on ...

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 ...
