Alexander Mikhailovich 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] |
Viperidae
The Viperidae (vipers) are a family of snakes found in most parts of the world, except for Antarctica, Australia, Hawaii, Madagascar, and various other isolated islands. They are venomous and have long (relative to non-vipers), hinged fangs that permit deep penetration and injection of their venom. Four subfamilies are currently recognized. They are also known as viperids. The name "viper" is derived from the Latin word ''vipera'', -''ae'', also meaning viper, possibly from ''vivus'' ("living") and ''parere'' ("to beget"), referring to the trait viviparity (giving live birth) common in vipers like most of the species of Boidae. Description All viperids have a pair of relatively long solenoglyphous (hollow) fangs that are used to inject venom from glands located towards the rear of the upper jaws, just behind the eyes. Each of the two fangs is at the front of the mouth on a short maxillary bone that can rotate back and forth. When not in use, the fangs fold back against the ro ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Abkhazia
Abkhazia, ka, აფხაზეთი, tr, , xmf, აბჟუა, abzhua, or ( or ), officially the Republic of Abkhazia, is a partially recognised state in the South Caucasus, recognised by most countries as part of Georgia, which views the region as an autonomous republic.Olga Oliker, Thomas S.

Sukhumi
Sukhumi (russian: Суху́м(и), ) or Sokhumi ( ka, სოხუმი, ), also known by its Abkhaz name Aqwa ( ab, Аҟәа, ''Aqwa''), is a city in a wide bay on the Black Sea's eastern coast. It is both the capital and largest city of the Republic of Abkhazia, which has controlled it since the Abkhazia war in 1992–93. However, internationally Abkhazia is considered part of Georgia. The city, which has an airport, is a port, major rail junction and a holiday resort because of its beaches, sanatoriums, mineral-water spas and semitropical climate. It is also a member of the International Black Sea Club. Sukhumi's history can be traced to the 6th century BC, when it was settled by Greeks, who named it Dioscurias. During this time and the subsequent Roman period, much of the city disappeared under the Black Sea. The city was named Tskhumi when it became part of the Kingdom of Abkhazia and then the Kingdom of Georgia. Contested by local princes, it became part of the Otto ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
