Lycodon Bicolor
''Lycodon bicolor'', commonly known as the two-coloured wolf snake, bicolored wolf snake, golden wolf snake, and Mackinnon's wolf snake, is a species of colubrid snake native to the Western Himalayas. Distribution ''Lycodon bicolor'' is restricted to the western Himalayas, ranging from Uttarakhand in India east through Jammu & Kashmir to POK in Pakistan. It was originally described from Mussoorie, but was not found again at its type locality for over 112 years until it was rediscovered in 2019 during survey work in Binog Wildlife Sanctuary; these findings were reported in 2021. As Mussoorie is a major tourist destination, ''L. bicolor'' may be threatened by vehicular traffic, pollution, and other tourism-related activities near the sanctuary; due to this, a detailed status survey and further research into the species are required.Wall (1906). Description Adults may attain a total length of , which includes a tail long. Dorsally, it is brown, with a network of white lines. ...

Alexander Nikolsky
Alexander Mikhailovich Nikolsky (Russian: Александр Михайлович Никольский; February 18, 1858 – December 8, 1942) was a Russian and Ukrainian zoologist born in Astrakhan. From 1877 to 1881, he studied at the University of St. Petersburg, earning his doctorate several years later in 1887. From 1881 to 1891, he took part in numerous expeditions to Siberia, the Caucasus, Persia, Japan, et al. In 1887 he became an associate professor in St. Petersburg, later becoming director of the herpetology department at the Zoological Museum of the Academy of Sciences (1895). In 1903 he relocated as a professor to the Kharkiv University. In 1919 he was elected a member at the Academy of Sciences of Ukraine. Among his written works were ''Herpetologia Caucasica'' (1913), and volumes on reptiles and amphibians that were part of the series "Fauna of Russia and Adjacent Countries". He is the taxonomic authority of 26 reptile species. The viper '' Vipera nikolskii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourism
Tourism is travel for pleasure, and the Commerce, commercial activity of providing and supporting such travel. World Tourism Organization, UN Tourism defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be Domestic tourism, domestic (within the traveller's own country) or International tourism, international. International tourism has both incoming and outgoing implications on a country's balance of payments. Between the second half of 2008 and the end of 2009, tourism numbers declined due to a severe Economy, economic slowdown (see Great Recession) and the outbreak of the 2009 2009 flu pandemic, H1N1 influenza virus. These numbers, however, recovered until the COVID-19 pandemic put an abrupt end to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reptiles Described In 1903
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and amniotic development. Living traditional reptiles comprise four orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia ( ), which corresponds to common usage. Modern cladistic taxonomy regards that group as paraphyletic, since genetic and paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among reptiles from an evolutionary perspective. Many cladistic systems therefore redefine Reptilia as a clade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycodon
''Lycodon'' is a genus of colubrid snakes, commonly known as wolf snakes. The Neo-Latin name ''Lycodon'' is derived from the Greek words λύκος (''lykos'') meaning wolf and οδόν (''odon'') meaning tooth, and refers to the fang-like anterior maxillary and mandibular teeth. They are nonvenomous, but many members of this genus strongly resemble the venomous kraits in appearance, an example of Emsleyan mimicry. Fossil record Fossils of ''Lycodon'' are known from the Early Pliocene of Henan. Species The genus ''Lycodon'' comprises 73 recognized species. *'' Lycodon albofuscus'' – dark wolf snake *'' Lycodon alcalai'' – Alcala's wolf snake *'' Lycodon anakradaya'' *'' Lycodon anamallensis'' – Colombo wolf snake *'' Lycodon aulicus'' – Indian wolf snake, common wolf snake *'' Lycodon banksi'' Luu et al., 2018 – Banks's wolf snake *'' Lycodon bibonius'' – Ota's wolf snake *'' Lycodon bicolor'' – Mackinnon's wolf snake *'' Lycodon butleri'' ...

Oviparity
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or f ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malcolm Arthur Smith
Malcolm Arthur Smith (1875 in New Malden, Surrey – 1958 in Ascot) was a herpetologist and physician working in the Malay Peninsula. Early life Smith was interested in reptiles and amphibians from an early age. After completing a degree in medicine and surgery in London in 1898, he left for the then Kingdom of Siam (today Thailand) as a doctor to the British Embassy in Bangkok. In 1921, he married Eryl Glynne of Bangor, who as well as being medically trained, made significant collections of ferns from Thailand and later worked at RBG Kew. She was killed in a car crash near Bangkok in 1930. The couple had three children including the mountaineer Cymryd "Cym" Smith, also killed in a road accident. Eryl was the elder sister of the mountaineer and plant pathologist Mary Dilys Glynne. Work Smith went on to become the physician in the royal court of Siam and was a close confidant and a doctor to the royal family. He published his observations on the reptiles and amphibians during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Scale
In snakes, the anal scale or anal plate is the scale just in front of and covering the cloacal opening. This scale can be either single ("anal entire") or paired ("anal divided"). When paired, the division is oblique.Mallow D, Ludwig D, Nilson G (2003). ''True Vipers: Natural History and Toxicology of Old World Vipers''. Malabar, Florida: Krieger Publishing Company. 359 pp. . Wright AH, Wright AA (1957). ''Handbook of Snakes of the United States and Canada''. Ithaca and London: Comstock Publishing Associates. (7th printing, 1985). 1,105 pp. (in two volumes). . The anal scale is preceded by the ventral scales and followed by the subcaudal scales. See also *Snake scales Snakes, like other reptiles, have skin covered in scales.Boulenger, George A. 1890 The Fauna of British India. p. 1 Snakes are entirely covered with scales or scutes of various shapes and sizes, known as snakeskin as a whole.

Dorsal Scales
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government.
