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 ...

Macedonian Crested Newt
''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 (biology), hybrid between this species and the Balkan-Anatolian crested newt (''T. ivanbureschi''), and thus is a synonym of both species.

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Amphibians Of Europe
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...

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] |
Danube Crested Newt
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. ...

Hybridisation (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatolian Crested Newt
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 ...

Sibling Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...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.

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 ...
