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 ...

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 ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bursa
( grc-gre, Προῦσα, Proûsa, Latin: Prusa, ota, بورسه, Arabic:بورصة) is a city in northwestern Turkey and the administrative center of Bursa Province. The fourth-most populous city in Turkey and second-most populous in the Marmara Region, Bursa is one of the industrial centers of the country. Most of Turkey's automotive production takes place in Bursa. As of 2019, the Metropolitan Province was home to 3,056,120 inhabitants, 2,161,990 of whom lived in the 3 city urban districts (Osmangazi, Yildirim and Nilufer) plus Gursu and Kestel, largely conurbated. Bursa was the first major and second overall capital of the Ottoman State between 1335 and 1363. The city was referred to as (, meaning "God's Gift" in Ottoman Turkish, a name of Persian origin) during the Ottoman period, while a more recent nickname is ("") in reference to the parks and gardens located across its urban fabric, as well as to the vast and richly varied forests of the surrounding region ...

Bosphorus
The Bosporus Strait (; grc, Βόσπορος ; tr, İstanbul Boğazı 'Istanbul strait', colloquially ''Boğaz'') or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul in northwestern Turkey. It forms part of the continental boundary between Asia and Europe, and divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation. Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks. The Bosporus Strait and the Dardanelles Strait at the opposite end of the Sea of Marmara are together known as the Turkish Straits. Sections of the shore of the Bosporus in Istanbul have been reinforced with concrete or rubble and those sections of the Strait prone to deposition are periodically dredged. Name The name of the ...

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 ...

Vertebrae
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the vertebral column, backbone), and on the other with phylogenetic differences among the vertebrate taxon, taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra fo ... [...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 Cristatus
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 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-Anatolian 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 dif .. ...

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 t ... [...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 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.
