The origin of tiger salamander
(Ambystoma tigrinum) populations in California, Oregon, and Nevada: introductions or relicts?
Growth and foraging consequences of faeultative paedomorphosis in the tiger salamander
, Ambystoma tigrinum nebulosum.
In northern California, many California red-legged frog and California tiger salamander
populations occupy small artificial water impoundments, or stock ponds, created by cattle ranchers for the purpose of providing water for their cattle.

Recovery Plan is available at http://arizonaes.
We report results of a field experiment that tested joint effects of individual variation in body mass and density on growth and development of cohorts of larval Arizona tiger salamanders
(Ambystoma tigrinum nebulosum Hallowell).
First, we report the results of a survey of mitochondrial DNA (mtDNA) sequences from the entire tiger salamander
complex, including virtually all of the named species and subspecies.
Specific credits available include vernal pool creation, vernal pool preservation, California Tiger Salamander
breeding pond, and California Tiger Salamander
The most abundant salamanders were the smallmouth salamander, tiger salamander
, red-backed salamander (Plethodon cinereus), and unisexual salamander.
On July 22, due to an imminent threat of habitat destruction, we listed the Sonoma County distinct population segment of the California tiger salamander
as endangered under the emergency provisions of the ESA.
Larvae of the Arizona tiger salamander
, Ambystoma tigrinum nebulosum Hallowell, feed on a variety of prey and often exhibit an environmentally induced cannibal phenotype, making them ideal for investigating how prey type affects population size structure and trophic relations.
Threatened mountain-dwelling species include the boreal and Yosemite toads, the cascade frog and the tiger salamander
The district was recognized for its efforts to create 17 semi-permanent wetland ponds to provide habitat for protected species such as the California red-legged frog and the tiger salamander
The western tiger salamander
(Ambystoma mavortium) exhibits facultative paedomorphosis throughout many parts of its range (western North America).
The property turned out to support more than 100 acres (40 ha) of seasonal wetlands, including habitat of such endangered species as the Contra Costa goldfields (Lasthenia conjugens), vernal pool tadpole shrimp (Lepidurus packardi), and California tiger salamander
These six species are mole salamander (Ambystoma talpoideum), tiger salamander
