Query: Are newts amphibians?
Newts, as with salamanders in general and other amphibians, serve as bioindicators because of their thin, sensitive skin and evidence of their presence (or absence) can serve as an indicator of the health of the environment. Most species are highly sensitive to subtle changes in the pH level of the streams and lakes where they live. Because their skin is permeable to water, they absorb oxygen and other substances they need through their skin. Scientists study the stability of the amphibian population when studying the water quality of a particular body of water.
Newts are capable of associative learning. They are able to associate chemical signals from a novel predator with another chemical stimulus when the second stimulus is the skin extract of another newt.
The rough-skinned newt ("Taricha granulosa") is a newt known for its strong poison. Habitats of rough-skinned newts are found throughout the West Coast of the United States and British Columbia. Their range extends south to Santa Cruz, California and north to Alaska. Rough-skinned newts are rare in Idaho and have only been found in several ponds near Moscow, Idaho where they may have been introduced.
The spotted paddle-tail newt ("Pachytriton brevipes") is an amphibian native to southeastern China; it was named in 1876. A member of the family Salamandridae, it is closely related to the spotless paddle-tail newt ("Pachytriton labiatus"). The spotted paddle-tail newt lives in streams and is characterized by its long, paddle-shaped tail used for propulsion.
There are six native amphibians in Wales. They are the common toad, great crested newt, natterjack toad, palmate newt, smooth newt and common frog.

There are a variety of species represented within Kittitas County. These include a diversity of grasses, herbs, trees, birds, mammals and amphibians. The genus of ricegrass known as "Oryzopsis" was one of the earliest grasses classified within the county. Among the amphibian species found are the Cascades frog and the rough-skinned newt, the latter being a common far western USA taxon; in fact, examples of neoteny have been found in individual newts of this species within the county.Kittitas County is directed by a three-member Board of Commissioners.
When an isolated peptide termed "frog's nociception-related peptide" (fNRP) is injected into newts, it increases the latency for newts to flick their tails in response to a hot-beam. The effect is blocked by simultaneous injection of naloxone, thereby indicating evidence for the interaction of fNRP and opioid steps in the analgesia pathways of newts.
Eastern newts eat a variety of prey, such as insects, small mollusks and crustaceans, young amphibians, worms, and frog eggs.
Although eastern newts are widespread throughout North America, they, like many other species of amphibians are increasingly threatened by several factors including, habitat fragmentation, climate change, invasive species, over-exploitation, and emergent infectious diseases. Wild eastern newts are known hosts of "Batrachochytrium dendrobatidis" and "Ranavirus". They are also highly susceptible to the newly emergent chytrid fungus "Batrachochytrium salamandrivorans".
Nonylphenol is a large issue for "T. carnifex" because it is a very common toxin found in leakage from sewers into the habitat of the Italian crested newt. Newts are amphibians, and make their habitats in aquatic environments. These environments have been known to sometimes receive the previously discussed sewage leaking. The compounds nonylphenol as well as ethoxylate surfactants can be found in polluted rivers, where the newts reside. The two substances discussed can be transformed, by microorganisms, into compounds which are much more toxic. They are extremely good bioindicators, due to the magnification of these chemicals in the environment demonstrated in the newt. Nonylphenol absorbed through the newts’ skin is especially dangerous because it can result in issues with the reproductive biology as well as cutaneous and osmoregulatory mechanisms.
The presence of four British reptiles; common lizard, adder, slowworm, and grass snake, and five of Britain’s native amphibians; common frog, common toad, smooth newt, palmate newt, and great crested newt mean that this an extremely valuable and important wildlife site. The grass snake records for Fontburn make this one of the most northerly authenticated colonies of this species in Britain.
The species of amphibian native to England are the great crested newt, smooth newt, palmate newt, common toad, natterjack toad, common frog and the pool frog. Several other species have become naturalised.
The Hong Kong warty newt or Hong Kong newt (Paramesotriton hongkongensis, see also the synonyms) is the only species of salamander (also known as the "tailed amphibian"), found in Hong Kong. Once thought to be endemic to the territory, the species has also been found in the coastal parts of Guangdong Province.
Amphibians are common in the capital, including smooth newts living by the Tate Modern, and common frogs, common toads, palmate newts and great crested newts. On the other hand, native reptiles such as slowworms, common lizards, grass snakes and adders, are mostly only seen in Outer London.
Only six amphibians and four land reptiles are native to Scotland. The amphibians include three species of newt: the great crested, of which fewer than 1,000 individuals survive; the smooth, and the palmate. The other amphibians are the common toad, the natterjack toad, found in only four locations in the south-west, and the common frog. A single alien amphibian is known in Scotland, the Alpine newt, a recent escapee confined to the Edinburgh area.
The alpine newt (Ichthyosaura alpestris) is a newt of the salamander order Caudata (or Urodela) in the class of amphibians.
It was formerly known as "Triturus alpestris" and "Mesotriton alpestris".
Newts are traditionally associated with witchcraft. In William Shakespeare's play Macbeth, the witches use "eye of newt" as the first ingredient added to their cauldron.
Spegeldammen is an important breeding ground for several species of amphibians, including smooth newt, great crested newt, common frog, and common toad, and several ponds have been created solely for promoting the precondition for breeding amphibians. Grass snakes are also found both in the lake and in the surrounding area.
The range of the northern crested newt extends from Great Britain and Brittany in the west, across much of Europe north of the Alps, and southeast to the Black Sea. It is the biggest and least common of the three newts found in the British Isles and is one of only four amphibians which are protected by the UK Biodiversity Action Plan.
The great crested newt "Triturus cristatus" is an amphibian native to the UK but also widespread across Northern Europe. Whilst it is relatively widespread in the UK (in fact the UK hosts one of the great crested newt's most significant populations), it is rare on a European wide basis. The great crested newt is listed as a "strictly protected fauna species" under appendix II of the Convention on the Conservation of European Wildlife and Natural Habitats:
and consequently is protected under UK legislation through the Wildlife and Countryside Act and the Conservation (Natural Habitat) regulations 1994. Under these regulations it is an offence to intentionally disturb, injure or kill any great crested newt, or disturb or destroy its habitat. Likewise, the Habitats Regulations 2010 do not apply to all newts, and in the case of e.g. smooth newt species, they are protected differently, under the Wildlife and Countryside Act 1981 (as amended).
The amphibian adrenal gland is responsible for the release of corticosteroids and catecholamines which aid in stress response in the newts by maintaining ion and water balance. This allows them to adapt and moderate environmental changes in their habitats. However, the introduction of cadmium into aquatic systems has been shown to disrupt normal operation of the adrenal gland in amphibians and result in a marked drop in ACTH (a hormone secreted by the anterior pituitary gland which triggers an increase in production of corticosterone) and therefore also a drop in corticosterone production. A drop in these necessary hormones severely affects the survivability of the newt, and its hypersensitivity towards chemical and pollutant exposure serves to cripple "T. carnifex"'s longevity further.
Approximately one half of the amphibian species of the islands are endemic. Endemic amphibians include the sword-tail newt, "Hyla hallowellii", Holst's frog, Otton frog, Ishikawa's frog, the Ryukyu tip-nosed frog, and Namiye's frog. Other rare amphibians include Anderson's crocodile newt and the Kampira Falls frog.
Newt fencing is a barrier designed to control the movement of Great Crested Newts, other amphibians or reptiles. It can also be called drift fencing or temporary amphibian fencing (TAF). It consists of a low fence of plastic sheeting, buried a short way into the ground and supported by lightweight posts usually made of wood or plastic. It is used to keep animals out of working areas, to keep them inside safe areas of their habitat, to intercept migration routes, or to control their movement to help their capture for translocation. It may be used in conjunction with pitfall traps placed at the foot of the fence. It is most commonly used in connection with building projects, to minimise harm to protected species.
This is a list of the amphibians of Great Britain. There are seven amphibian species native to Great Britain, in addition, there are a number of naturalized species. The natives comprise three newts, two toads and two frogs.
The rough-skinned newt ("Taricha granulosa") is a newt known for its strong poison. Habitats of rough-skinned newts are found throughout the West Coast of the United States and British Columbia. Their range extends south to Santa Cruz, California and north to Alaska.
