danube crested newt

Ommatotriton ophryticus, the northern banded newt, is a species of newt in the family Salamandridae. The smooth newt, northern smooth newt or common newt is a species of newt commonly found throughout Europe, except the far north, areas of Southern France and the Iberian Peninsula. Males develop a conspicuous jagged crest during the breeding season. The alpine newt is a species of newt native to continental Europe and introduced to Great Britain and New Zealand. 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. [9] :345. The belly is reddish orange with black blotches, Australia, Czech Republic, Slovekia, Bosnia, Romania, Ukraine, Moldova, and Serbia, Rivers, flooded marshland, ditches, meadows, bushlands, deciduous forests, and groves. [14] [15]. Before its description in 2016, it was first considered to belong to the southern crested newt and then the Balkan crested newt. It has sexual reproduction. [10] :10–14, The Danube crested newt's back and sides are dark brown with black spots and white stippling. Typical breeding sites are slow-flowing river margins, oxbow lakes, flooded marshland, larger ponds, or ditches, provided abundant underwater vegetation is available. Larvae develop two to four months in the water before reaching metamorphosis. It occurs from sea level to 2,500 m (8,200 ft) elevation. The Danube crested newt was described as a variety of the northern crested newt (Triturus cristatus) by C. Kiritzescu in 1903. http://eol.org/schema/terms/nearThreatened, http://apiv3.iucnredlist.org/api/v3/taxonredirect/22216, http://purl.obolibrary.org/obo/ENVO_00000873, http://purl.obolibrary.org/obo/GO_0019953, http://purl.obolibrary.org/obo/GAZ_00000071, http://rs.tdwg.org/ontology/voc/SPMInfoItems#ConservationStatus, http://www.iucnredlist.org/technical-documents/categories-and-criteria, http://eol.org/schema/terms/Pontic_steppe, https://www.worldwildlife.org/ecoregions/pa0814, http://purl.obolibrary.org/obo/RO_0002303, http://purl.obolibrary.org/obo/ENVO_00000233, http://purl.obolibrary.org/obo/ENVO_00002009, http://purl.obolibrary.org/obo/GO_0040011, https://www.wikidata.org/entity/Q21907045, https://eol.org/schema/terms/mineralizedSkeletonContains, http://purl.obolibrary.org/obo/CHEBI_52254, http://eol.org/schema/terms/population_trend, http://purl.obolibrary.org/obo/GO_0000003. Another feature of males at breeding season is a bluish-white stripe along the tail. [10] :58–59 Predators include herons and other birds, snakes such as the grass snake, and various carnivorous mammals. [3] Later, it was considered a subspecies until genetic analysis supported its recognition as a separate species in the crested newt species complex. [1], Danube crested newts have the longest aquatic phase in the genus Triturus. [10] :10–14 [9] :345 Females can sometimes have a yellow stripe along the back, similar to the Italian crested newt (T. carnifex). Schmidtler's smooth newt is a newt species found from northwestern Greece and southeast Bulgaria over East Thrace across the Bosphorus to northwest Anatolia. It has a smaller and more slender body than the other crested newts in genus Triturus but l The main threat is habitat destruction by humans, especially through drainage, damming, or pollution. Although the Danube Crested Newt often occurs in human neighborhoods, anthropogenic destruction of habitat leads to decline and extinction of this species in many sites. For example, building of dams in the Danube River, conversion of habitats into arable lands, eutrophication of breeding water bodies, etc., lead to extinction of some populations. Danube Crested Newt is found in the Palearctic. Like all crested newts, T. dobrogicus males develop a crest on their back and tail during breeding phase, which can be quite high and jagged, usually starts between the eyes and nostrils, and is interrupted at the tail base. Great Crested Newt (Triturus cristatus) - Guest from the wild - Animalia Kingdom Show - Duration: 2:40. Your email address will not be published. Great Crested Newt (Triturus cristatus)Great Crested Newts are the biggest newt species in the UK and have been around for approximately 40 million years. 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. Its range borders that of the smooth newt, the Greek smooth newt and Kosswig's smooth newt to the north, west, and east, respectively. The southern crested newt is a terrestrial European newt. "Intraspecific taxonomy and nomenclature of the Danube crested newt. Triturus dobrogicus (Danube Crested Newt) is a species of amphibians in the family Salamandridae. It is a large newt, growing up to 16 cm (6.3 in) in females. The belly is orange to red (in other crested newts, it is usually yellow or orange–yellow), with small or medium-sized black blotches that have sharp edges. [6] Later genetic study, however, did not support the distinction of these two forms. Currently, 74 species have been identified in the Northern Hemisphere - Europe, Asia, the northern tip of Africa, and North America. [1] Like the other crested newts, T. dobrogicus is listed in the Berne Convention (appendix II) and the EU Habitats Directive (annexes II and IV), and capture, disturbance, killing, trade, and destruction of habitats are prohibited. Reproduction is dioecious. [10] :78, The population of the Danube crested newt has declined significantly, and the International Union for Conservation of Nature has assessed its conservation status as "near threatened". Article was last reviewed on 14th September 2019. [10] :61–65 [9] :345, Both in water and on land, the newts are largely nocturnal. The northern crested newt, great crested newt or warty newt is a species of newt native to Europe and western Asia. It is associated with freshwater habitat. 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. In their aquatic habitats, they hide under vegetation, and on land, they use structures such as logs, rocks, or small animal burrows for cover. It has a slim and slender body but during the breeding season, the male newts grow a crest on their tails and backs. [10] :80–89 The eggs are fertilised internally. [10] :16–17, Compared to the other crested newt species, the Danube crested newt is more adapted to life along a river system and frequently occurs in flowing water and together with fish. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. They are widely distributed throughout Britain but this distribution is extremely patchy; they’re absent from Ireland and … It has a slim and slender body but during the breeding season, the male newts grow a crest on their tails and backs. This body shape has evolved through an increase in the number of rib-bearing vertebrae: there are 16–17 of them in T. dobrogicus, the highest number among the crested newts. It is closely related with several similar species that were previously classified as subspecies. Their skin is very granular because of the number of poison glands. The terrestrial juvenile phase is called an eft. The species is found in Portugal and western Spain. It differs from T. cristatus with the relatively shorter limbs and the markedly spotted belly. For the remainder of the year, the newts live in shady land habitats, usually forests. Danube Crested Newt is found in the Palearctic. It is listed as near threatened by IUCN. Triturus dobrogicus (Danube Crested Newt) is a species of amphibians in the family Salamandridae. Published on September 14th 2019 by staff under Newts. Eggs and larvae are smaller than in the other crested newt species, and they take longer (two to four months) until they reach metamorphosis and leave the water. Backs and sides are dark brown, while the belly is yellow to orange with dark blotches. [4] [5], Separated populations from the Danube Delta and the Pannonian Basin (see section Distribution and habitats) were described as two subspecies, T. dobrogicus dobrogicus and T. dobrogicus macrosoma, in 2000. [2] The northern crested newt is its sister species, according to phylogenomic studies. Most species of Salamandridae have moveable eyelids but lack lacrimal glands. Males perform a courtship display, and females lay around 200 eggs individually onto leaves of aquatic plants. Reproduction is dioecious. International Union for Conservation of Nature, "Unraveling the rapid radiation of crested newts (. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. The Italian crested newt is a species of newt in the family Salamandridae. Although not yet considered threatened, Danube crested newt populations have declined significantly, the reason being mainly habitat loss. The Danube Crested Newt (Triturus dobrogicus) is a species of concern belonging in the species group "amphibians" and found in the following area(s): Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Hungary, Republic of Moldova, Romania, Serbia, Slovakia, Ukraine. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. The Balkan crested newt or Buresch's crested newt is a newt species of the crested newt species complex in genus Triturus, found in Southeastern Europe and Anatolia. Danube crested newts eating. 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. The three species form a complex of morphologically indistinguishable cryptic species. Side and back are black spotted dark brown with white stippled patterns. As in other crested newts, a female lays around 200 eggs per season, which are folded individually into leaves of aquatic plants.

Kosswig's smooth newt is a newt species found in northwestern Anatolia, east of the Bosphorus. It has sexual reproduction. Not all aquatic salamanders are considered newts, however. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. [10] :44–48 [13] :144–145 During land phase, the newts live in deciduous forests or groves, bushlands, or meadows. When they have gained the female's interest, they guide it over a spermatophore they deposit on the ground, which the female then takes up with her cloaca. It is similar to the northern crested newt except larger and more robust. The Danube crested newt is named after the river the species is found at. The southern banded newt is a species of salamander in the family Salamandridae found in Iraq, Israel, Jordan, Lebanon, Syria, and Turkey. The Danube crested newt is named after the river the species is found at. Animalia Kingdom - Łukasz Karnatowski 5,930 views It is listed as near threatened by IUCN. 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. Males are more conspicuously coloured than the drab females, especially during breeding season. The Danube crested newt is found in three allopatric areas of distribution from central to eastern Europe: In addition to the northern crested newt to the north, the Danube crested newt's range borders that of the Italian crested newt (T. carnifex) in the west, and that of the Macedonian (T. macedonicus) and Balkan (T. ivanbureschi) crested newts in the south. EOL has data for 11 attributes, including: Known occurrences, collected specimens and observations of Danube Crested Newt. Negative factors. [10] :47–48,58 They feed mainly on different invertebrates, but in the water may also prey on tadpoles and smaller newts. Adults move to their breeding sites in February or March and usually stay there for six months; occasionally, they may even stay longer or return to the water in autumn.
