Description

provided by AmphibiaWeb articles
A. mavortium is a very large salamander, among the largest known in North America. It has a broad head and a stout body. There is substantial geographic variation in color and pattern. Typically a light gray to grayish black dorsum is overlain with scattered black or dirty yellow dots or a network of yellow bars and lines. Venter varies from light to as dark as the dorsum. Hatchlings display alternating dark and light middorsal blotches and a pale lateral stripe.Ambystoma mavortium consists of a number of former subspecies of Ambystoma tigrinum. A. tigrinum now solely refers to the subspecies A. tigrinum tigrinum while A. mavortium includes ex-subspecies A. t. diaboli, A. t. mavortium, A. t. melanostictum, A. t. nebulosum, and A. t. stebbinsi.

Distribution and Habitat

provided by AmphibiaWeb articles
A wide distribution through most of the western half of the US, only occasionally in California and Nevada. It extends from the southernmost tip of Texas up to Canada. The range has a broad north-south distribution but extends no further east than the Dakotas and Oklahoma. Populations have been introduced into southern Arizona through the human use of larvae as fish bait.Habitat is diverse - it includes bottom land deciduous forests, coniferous forests and woodlands, open fields and bushy areas, alpine and subalpine meadow, grasslands, semideserts and deserts, and (rarely) in streams. Sandy or friable soils make for good breeding ground.

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Declines in A. mavortium have been reported; deforestation and habitat loss in wetland and other areas are widely reported as causes. Introduction of predatory fish is not well-investigated but could potentially be an important cause of declines. Other possible causes for declines include acid-rain (Harte and Hoffman 1989), although that cause is contentious.

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Cannabilistic larval morphs exist but show geographic variation in prevalence. Breeding takes place in practically every month of the year and is environmentally influenced, especially by such factors as rainfall and elevation. Breeding takes place in both temporary and permanent locations. Eggs are deposited singly or in very small clusters.

Brief Summary

provided by EOL authors
The barred tiger salamander is an amphibian characterized by yellow to tannish vertical bars set upon a dark brown to black background color. The bars can vary in thickness depending on the metapopulation. The taxon distribution is defined as central Nebraska south to southern Texas and west to central Colorado and New Mexico. This species is a threat to the survival of the taxon Ambystoma tigrinum stebbinsi, the latter which has a more limited range and is classified as endangered. The two taxa are sufficiently similar in appearance, that genetic testing may be required to discriminate.

Barred tiger salamander

provided by wikipedia EN

The barred tiger salamander or western tiger salamander (Ambystoma mavortium) is a species of mole salamander that lives in lower western Canada, the western United States and northern Mexico.[1][2]

Description

Development

The barred tiger salamander typically grows from 15 to 22 cm (5.9 to 8.7 in) but it can grow to 30.5 cm (12.0 in) long at the most and is one of the largest species of salamander in North America. It has a broad head and a sturdy body. The color is variable across its range. The dorsal surface is grey, dark brown or black with bars and spots of muddy yellow giving it a tiger-like coloring. The ventral surface varies from light to dark. Larvae have alternating dark and light blotches on the centre of the dorsal surface and pale stripes running along the sides.[1]

Behavior

Primarily nocturnal, barred tiger salamanders are opportunistic feeders, and will often eat anything they can catch, including various insects, slugs, and earthworms. They are primarily terrestrial as adults, but their juvenile, larval stage is entirely aquatic, having external gills. Breeding takes place during most months of the year. The eggs are laid in water and the developing larvae are exclusively aquatic.

Cannibalism

There are two main feeding morphologies for barred tiger salamanders, typical and cannibalistic. The cannibalistic form is characterized by large vomerine teeth, slim bodies and wider heads. The teeth give a better hold on prey, and the wider heads allow for eating larger organisms. In some areas, these include fathead minnows. Since the two species have similar diets, eating a competitor also reduces demand on their shared food.[3]

Cannibalistic tiger salamanders tend to metamorphosize earlier than the typical ones. Most often, cannibals are found in drier areas and shallow, more competitive waters, making earlier metamorphosis advantageous.[3]

Subspecies

The five recognized subspecies of Ambystoma mavortium are:

  • Gray barred tiger salamander, A. m. diaboli (Dunn, 1940)
  • Barred tiger salamander, A. m. mavortium (Baird, 1850)
  • Blotched tiger salamander, A. m. melanostictum (Baird, 1860)
  • Arizona tiger salamander, A. m. nebulosum (Hallowell, 1853)
  • Sonoran tiger salamander, A. m. stebbinsi (Lowe, 1954)
a.m. diaboli, salamander in residence at Living Prairie Museum, Winnipeg

Distribution and habitat

The barred tiger salamander lives in western Canada and the western half of the United States, but infrequently in California and Nevada. In Canada it is known from British Columbia, Alberta, Saskatchewan and Manitoba. Its range in the United States extends to the southernmost tip of Texas, but no further east than the Dakotas and Oklahoma.[1][2] It has been introduced into southern Arizona because its larvae are used as fish bait.[1]

It is a mainly terrestrial species, living in lowland deciduous forests, coniferous forests and woodlands. It also inhabits open fields, rough ground, upland meadows, grasslands, deserts, semideserts and streams.[1]

Status

The Sonoran tiger salamander was classified as an endangered species in 1997, due to increased human activity causing degradation and fragmentation of its habitat. It is also threatened by various disease outbreaks triggered by species not native to Arizona. Some introduced animals, such as crayfish, prey on it.[1]

In captivity

Tiger salamanders are frequently kept in captivity; they mostly hide and ambush their prey. It is illegal to sell adults in most parts of the United States. Their large size allows for ease of feeding, and their hardy nature makes them excellent captives. Their larval stage is often sold as fishing bait, marketed as "mud puppies" or "water dogs".[4]

Symbol

The tiger salamander is the state amphibian of Kansas. The second grade class of 1993 of O‑K Elementary in Wichita, Kansas, petitioned the governor; students Timothy Boyd and Kristofer Voorhees presented the initial idea for a state amphibian to their teacher.[5] It is also the state amphibian of Colorado after being recognized by the Colorado legislature on March 16, 2012.[6]

Ambystoma mavortium ( Spanish; Castilian )

provided by wikipedia ES

La salamandra tigre de Texas o salamandra tigre barrada (Ambystoma mavortium) es una especie de anfibio urodelo de la familia Ambystomatidae o salamandras topo.[2]​ Se distribuye desde el sudoeste de Canadá (Columbia Británica, Alberta, Saskatchewan y Manitoba) y el sur y oeste de los Estados Unidos hasta Texas y el norte de México. De hábitos terrestres, acude al agua para criar.

Descripción

 src=
Desarrollo

La salamandra tigre de Texas es una de las especies de salamandras terrestres más grandes, pudiendo llegar a crecer hasta 35 centímetros, aunque el tamaño más común es de 15 a 30 centímetros. Tiene la cabeza de gran tamaño y un cuerpo voluminoso, su piel es húmeda y normalmente color café oscuro a verde oliva, o a veces negra con grandes manchas amarillas. La coloración ventral varía de clara a oscura.

Comportamiento

De hábitos marcadamente nocturnos, la salamandra tigre de Texas es un predador oportunista que devora cualquier cosa que pueda atrapar, incluyendo insectos, babosas, lombrices de tierra y en algunos casos roedores. En la fase adulta es principalmente terrestres, mientras que en la fase larval juvenil es enteramente acuática teniendo branquias externas. La época reproductiva abarca la mayor parte del año, depositando los huevos en el agua, donde eclosionarán.

Subespecies

Existen cinco subespecies reconocidas de Ambystoma mavortium:[2]

  • Salamandra tigre gris, Ambystoma mavortium diaboli (Dunn, 1940)
  • Salamandra tigre barrada, Ambystoma mavortium mavortium (Baird, 1850)
  • Salamandra tigre manchada, Ambystoma mavortium melanostictum (Baird, 1860)
  • Salamandra tigre de Arizona, Ambystoma mavortium nebulosum (Hallowell, 1853)
  • Salamandra tigre de Sonora, Ambystoma mavortium stebbinsi (Lowe, 1954)

Vida en cautividad

La cría en cautividad de la salamandra tigre barrada es bastante frecuente. Su venta es legal y es común hallarla en tiendas de mascotas en el suroeste de Estados Unidos. Su gran tamaño les permite alimentarse fácilmente. Su larva es frecuentemente vendida como cebo para la pesca, y se les conoce en el mercado como perros de agua.

Simbología

La salamandra tigre de Texas es el anfibio estatal de Kansas desde 1993 y de Colorado desde el 16 de marzo de 2012.

Ambystoma mavortium

Il s'agit d'une des plus grandes salamandres d'Amérique du Nord qui peut atteindre 35 cm de long. Sa queue semble un peu aplatie comme pour la plupart des espèces de salamandres tigrées. Sa peau, de texture humide, est de couleur brun foncé à vert olive ou noir et est couverte de taches jaunes ce qui fait penser à la couleur d'un tigre.

Il s'agit d’un animal nocturne qui se nourrit d'insectes et de vers. Adulte, il s’agit d’un animal terrestre mais ses larves sont aquatiques et possèdent des branchies externes.

Jusqu'à six sous-espèces sont reconnues[4].

Taxinomie

Certains scientifiques considèrent que cette espèce est synonyme de Ambystoma tigrinum[5].

Symbole

Cette espèce est l'amphibien symbole du Kansas.

生態[編集]

森林や半砂漠地帯に生息する。夜行性で、昼間は小動物が掘った巣穴などで休む。地域によっては共食いを行い大型化することもある。逆に寒冷地や乾燥地等の地域では、幼生の期間が短く大型化しないとされる。

食性は動物食で、昆虫類節足動物甲殻類、陸棲の貝類、小型両生類、小型爬虫類、小型哺乳類などを食べる。貪欲で目の前で動くものには食いつく。

繁殖形態は卵生。や水たまり等の卵を捕食する生物のいない止水中に卵を産む。環境によっては幼形成熟する。

人間との関係[編集]

アリゾナ州では州を代表する両生類に選ばれている。

ペットとして飼育されることもあり、日本にも輸入されている。主に基亜種が流通する。有尾類の中では丈夫で、餌付きやすいことから陸棲有尾類の飼育入門種として紹介されることもある。テラリウムで飼育される。大型種のためやや大型のケージを用意する。ミズゴケ腐葉土などの床材を敷き、流木コルクバーグ植木鉢などを設置してで隠れ家にする。全身が漬かれる水容器を用意する。カエルツボカビ症の伝播や定着の危険性があるため、一度飼育した個体を遺棄してはいけない。
