Tylototriton Notialis
''Tylototriton notialis'', the Laos knobby newt, is a species of newt in the family Salamandridae. It is only known from its type locality in the Nakai-Nam Theun Biodiversity Conservation Area, Khammouane Province, central Laos. The type locality is an evergreen mixed deciduous–pine forest; the newts were found in and near a small stream. It is likely that Laos knobby newt will also be found in adjacent areas of Vietnam. Based on molecular genetic data, it belongs to the ''Tylototriton asperrimus'' group of knobby newts. Laos knobby newt is a small newt, with total length of about .

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

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 ...

Salamandridae
Salamandridae is a family of salamanders consisting of true salamanders and newts. 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. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands. Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from in length. Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals that males perform ...

Nakai-Nam Theun Biodiversity Conservation Area
Nakai-Nam Theun National Park in Nakai District, Khammouane Province, Laos, is one of the last remaining wildernesses in Southeast Asia. Nakai-Nam Theun covers approximately 4,270 km2 of the Annamite Range and the adjacent Nakai Plateau in Khammouane and Bolikhamsai Provinces. It was designated a national park on 15 February 2019 by Prime Ministerial Decree No. 36, 15 February 2019. It is managed by the Ministry of Agriculture and Forestry (MAF). It is adjacent to the Vu Quang National Park of Vietnam. Rivers From north to south, riversheds in the park consist the following rivers: *Nam Kata (eastern part only; the Nam Houay, on which the town of Na Kadok is located, is a tributary) *Nam Xot *Nam Mon *Nam Theun *Nam Noy *Nam Pheo (a tributary of the Nam Noy) *Nam One All are tributaries of the Nam Theun to the southwest in the Nakai Plateau.

Laos
Laos (, ''Lāo'' )), officially the Lao People's Democratic Republic ( Lao: ສາທາລະນະລັດ ປະຊາທິປະໄຕ ປະຊາຊົນລາວ, French: République démocratique populaire lao), is a socialist state and the only landlocked country in Southeast Asia. At the heart of the Indochinese Peninsula, Laos is bordered by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the southeast, and Thailand to the west and southwest. Its capital and largest city is Vientiane. Present-day Laos traces its historic and cultural identity to Lan Xang, which existed from the 14th century to the 18th century as one of the largest kingdoms in Southeast Asia. Because of its central geographical location in Southeast Asia, the kingdom became a hub for overland trade and became wealthy economically and culturally. After a period of internal conflict, Lan Xang broke into three separate kingdoms: Luang Phrabang, Vientiane and Champasak. In ...

Tylototriton Asperrimus
The black knobby newt (''Tylototriton asperrimus'') is a species of salamanders in the family Salamandridae found in China and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss and overharvesting Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term app .... The black knobby newt is a medium-sized newt, with total length of .

Endemic Fauna Of Laos
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
