Triturus
''Triturus'' is a genus of newts comprising the crested and the marbled newts, which are found from Great Britain through most of continental Europe to westernmost Siberia, Anatolia, and the Caspian Sea region. Their English names refer to their appearance: marbled newts have a green–black colour pattern, while the males of crested newts, which are dark brown with a yellow or orange underside, develop a conspicuous jagged seam on their back and tail during their breeding phase. Crested and marbled newts live and breed in vegetation-rich ponds or similar aquatic habitats for two to six months and usually spend the rest of the year in shady, protection-rich land habitats close to their breeding sites. Males court females with a ritualised display, ending in the deposition of a spermatophore that is picked up by the female. After fertilisation, a female lays 200–400 eggs, folding them individually into leaves of water plants. Larvae develop over two to four months before met ...

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 courtship display, 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 metamorphosis, metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwellin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triturus Dobrogicus
The Danube crested newt or Danube newt (''Triturus dobrogicus'') is a species of newt found in central and eastern Europe, along the basin of the Danube river and some of its tributaries and in the Dnieper delta. It has a smaller and more slender body than the other crested newts in genus ''Triturus'' but like these, males develop a conspicuous jagged seam on back and tail during breeding season. For half of the year or longer, adults live in slow-flowing river margins, lakes, or ponds, where reproduction takes place. Males perform a courtship display, and females lay around 200 eggs individually onto leaves of aquatic plants. Larvae develop two to four months in the water before reaching metamorphosis. For the remainder of the year, the newts live in shady land habitats, usually forests. Although not yet considered threatened, Danube crested newt populations have declined significantly, the reason being mainly habitat loss. The species is protected by law in the European Union. ...

Triturus Anatolicus
The Anatolian crested newt (''Triturus anatolicus'') is a species of newt endemic to northern Anatolia in Turkey. Before its description in 2016, it was initially 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. Systematics and taxonomy The Anatolian crested newt was described by Ben Wielstra and Jan Willem Arntzen in 2016. Mitochon ...

Triturus Macedonicus
''Triturus macedonicus'', the Macedonian crested newt, is a newt species of the crested newt species complex in genus ''Triturus'', found in the Western Balkan peninsula (Bosnia-Herzegovina, Albania, North Macedonia, north-western Greece and south-western Bulgaria). To the North, its range borders that of the Danube crested newt and the Northern crested newt and to the East, that of the Balkan crested newt. It was first described as a variety of '' Triturus karelinii'', later considered a subspecies of '' Triturus carnifex'', and was elevated to species rank following molecular phylogenetic analysis in 2007. ''Triturus arntzeni'' was considered a synonym of ''T. macedonicus'', but this name applies in fact to a hybrid Hybrid may refer to: Science * Hybrid (biology), an offspring resulting from cross-breeding ** Hybrid grape, grape varieties produced by cross-breeding two ''Vitis'' species ** Hybridity, the property of a hybrid plant which is a union of two diff ... between th ...

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 population ...

Newts
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 ...

Triturus Carnifex
The Italian crested newt (''Triturus carnifex'') is a species of newt in the family Salamandridae. Habitat ''Triturus carnifex'' is found in parts of the Balkans and Italy. It is an aquatic breeder that can spend up to four months in the water.(Arntzen, J.W., Themudo, G.E., Wielstra, B. 2007. The phylogeny of crested newts (Triturus cristatus superspecies): nuclear and mitochondrial genetic characters suggest a hard polytomy, in line with the paleogeography of the centre of origin. Contributions to Zoology 76(4):261-278.) The location of the ponds where they breed affects the time when ''T. carnifex'' enters the water. ''T. carnifex'' prefers living in deep water since it is a nektonic species: it swims freely and is independent of currents. The absence of predatory fish may also explain why ''T. carnifex'' is inclined to ponds, rather than other larger bodies of water. They typically prefer ponds in northern Europe, where temperatures are colder . Adult ''T. carnifex'' start to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triturus Karelinii
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 those o ...

Triturus Pygmaeus
The southern marbled newt or pygmy marbled newt (''Triturus pygmaeus'') is a species of salamander in the family Salamandridae. It is found in Portugal and Spain. Its natural habitats are temperate forests, Mediterranean-type shrubby vegetation, rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, rural gardens, water storage areas, ponds, open excavations, irrigated land, canals and ditches. It is threatened by habitat loss. Previously thought to be a subspecies of the marbled newt (''Triturus marmoratus''), it was raised to species level after genetic studies revealed its distinctiveness from the former. Distribution The southern marbled newt occurs only in southern Portugal and southwestern Spain, in Mediterranean climate. The Douro–Tagus watershed forms a narrow, northern border to the range of ''Triturus marmoratus''. Description The southern marbled newt is similar in appearance to the marbled newt but is smaller, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Newt
The alpine newt (''Ichthyosaura alpestris'') is a species of newt native to continental Europe and Introduced species, introduced to Great Britain and New Zealand. Adults measure and are usually dark grey to blue on the back and sides, with an orange belly and throat. Males are more conspicuously coloured than the drab females, especially during breeding season. The alpine newt occurs at high altitude as well as in the lowlands. Living mainly in forested land habitats for most of the year, the adults migrate to puddles, ponds, lakes or similar water bodies for breeding. Males court females with a ritualised courtship display, display and deposit a spermatophore. After fertilisation, females usually fold their eggs into leaves of water plants. The aquatic larvae grow up to in around three months before metamorphosis, metamorphosing into terrestrial juvenile efts, which mature into adults at around three years. In the southern range, the newts sometimes do not metamorphose but ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
