Southern Crested Newt
The southern crested newt (''Triturus karelinii'') is a terrestrial European newt. It is similar to the northern crested newt (''Triturus cristatus'') except larger and more robust. In 2013, the Balkan-Anatolian crested newt (''Triturus ivanbureschi'') was separated from the southern crested newt, and in 2016, the Anatolian crested newt (''Triturus anatolicus'') was separated from ''T. ivanbureschi'', henceforth just the Balkan crested newt. Physical characteristics Southern crested newts are brown to gray dorsally, with darker patches scattered about. Their bellies and throats are orange, with small black dots. They grow up to 7.1 in (18 cm).livingunderworld.or Accessed 12/22/06 Males have a large jagged crest from behind their necks down to their tails. Range Southern crested newts occur on Crimea, and in the Caucasus and south of the Caspian Sea, whereas the populations on the southeast Balkan peninsula and western Anatolia belong to the Balkan crested newt while thos ...

Alexander Strauch (naturalist)
Alexander Strauch (1 March 1832, in Saint Petersburg – 14 August 1893, in Wiesbaden, Germany) was a Russian naturalist, most notably a herpetologist. In 1861 he started working as a curator of the zoological museum at the Imperial Academy of Sciences in St. Petersburg. From 1879 to 1890 he was director of the museum. He is credited with establishing St. Petersburg as a major world center in the field of herpetology. Taxa named after Strauch Taxa with the specific epithet of ''strauchi'' or ''strauchii'' commemorate his name, five examples being: *''Blanus strauchi'' ( Bedriaga, 1884) *'' Ctenotus strauchii'' ( Boulenger, 1887) *''Eremias strauchi'' Kessler, 1878 *'' Gloydius strauchi'' (Bedriaga, 1912) *'' Phrynocephalus strauchi'' Nikolsky, 1899. ''Nota bene'': A Taxon author in parentheses indicates that the species was originally described in a different genus. His zoologist author abbreviation is Strauch.

Newt
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. Newts are threatened by habitat loss, fragmentation and pollution. Several species are endangered, and at least one species, the Yunnan lake newt, has become extinct recently. Etymology The Old English name of the animal was , (of unknown origin), resulting in Middle English ; this word was transformed irregularly into , , or . The initial "n ...

Northern Crested Newt
The northern crested newt, great crested newt or warty newt (''Triturus cristatus'') is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. It is a large newt, with females growing up to long. Its back and sides are dark brown, while the belly is yellow to orange with dark blotches. Males develop a conspicuous jagged crest on their back and tail during the breeding season. The northern crested newt spends most of the year on land, mainly in forested areas in lowlands. It moves to aquatic breeding sites, mainly larger fish-free ponds, in spring. Males court females with a ritualised display and deposit a spermatophore on the ground, which the female then picks up with her cloaca. After fertilisation, a female lays around 200 eggs, folding them into water plants. The larvae develop over two to four months before metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwelling newts mainly feed on different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triturus Ivanbureschi
The Balkan crested newt or Buresch's crested newt (''Triturus ivanbureschi'') is a newt species of the crested newt species complex in genus ''Triturus'', found in Southeastern Europe and Anatolia. It was originally described as a subspecies of the southern crested newt, "''Triturus karelinii arntzeni''", in 1999, and later considered a full species when genetic data showed it to be distinct. After it was suggested the type specimen of "''T. arntzeni''" belonged in fact to the Macedonian crested newt (''T. macedonicus''), the species was redescribed, with a new type specimen, as ''T. ivanbureschi'' in 2013. The species epithet was chosen in honour of Bulgarian herpetologist Ivan Buresh. Its distribution ranges from the Southeastern Balkan peninsula (Western North Macedonia, Northwestern Greece, Bulgaria, Eastern Thrace) to Western Anatolia. An isolated population, surrounded by other crested newt species, occurs in Serbia. Genetic data showed that Northern Anatolian populati ...

Triturus Anatolicus
The Anatolian crested newt (''Triturus anatolicus'') is a newt species endemic to northern Anatolia in Turkey. Before its description in 2016, it was first considered to belong to the southern crested newt (''Triturus karelinii'') and then the Balkan crested newt (''Triturus ivanbureschi''). The three species form a complex of morphologically indistinguishable cryptic species. Genetic data demonstrated the Anatolian crested newt to be distinct from the other two species, although it hybridises with the Balkan crested newt at its western range end. With its two closely related species, the Anatolian crested newt is more stockily built than the other crested newts, and reaches 10–13 cm in length. It is semiaquatic, spending most of the year on land and only returning to water for breeding. The species does not seem to be immediately threatened, although a formal IUCN Red List assessment has not been conducted yet. Systematics and taxonomy The Anatolian crested newt was ...

Crimea
Crimea, crh, Къырым, Qırım, grc, Κιμμερία / Ταυρική, translit=Kimmería / Taurikḗ ( ) is a peninsula in Ukraine, on the northern coast of the Black Sea, that has been occupied by Russia since 2014. It has a population of 2.4 million. The peninsula is almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Sivash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. Crimea (called the Tauric Peninsula until the early modern period) has historically been at the boundary between the classical world and the steppe. Greeks colonized its southern fringe and were absorbed by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caucasus
The Caucasus () or Caucasia (), is a region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, Georgia, and parts of Southern Russia. The Caucasus Mountains, including the Greater Caucasus range, have historically been considered as a natural barrier between Eastern Europe and Western Asia. Mount Elbrus in Russia, Europe's highest mountain, is situated in the Western Caucasus. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands, part of which is in Turkey. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is occupied by several independent states, mostly by Armenia, Azerbaijan, and Georgia, but also ...

Caspian Sea
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east) and a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The sea stretches nearly from north to south, with an average width of . Its gross coverage is and the surface is about below sea level. Its main freshwater inflow, Europe's longest river, the Volga, enters at the shallow north end. Two deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broadleaf 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 ...

Coniferous
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
