Description
The California tiger salamander is a relatively large, secretive amphibian
Habitat and range
The California tiger salamander depends on
Historically, the California tiger salamander probably occurred in grassland habitats throughout much of the state.[
The six populations are found in Sonoma County, the Bay Area (Stanislaus County, western Merced County, and most of San Benito County), the Central Valley, the southern San Joaquin Valley, the Central Coast Range, and Santa Barbara County.[7][12][13]
The loss of California tiger salamander populations has been due primarily to human destruction of habitat and predators, such as American bullfrogs and access to breeding habitats.[14][15] There is also a viable hybrid between the California tiger salamander and the introduced barred tiger salamander (Ambystoma tigrinum mavortium), which genetic evidence suggests have been hybridizing for 50–60 years.[16]
Life cycle
Adults spend the majority of their lives underground, in burrows created by other animals, such as
Reproduction
Breeding takes place after the first rains in late fall and early winter, when the wet season allows the salamanders to migrate to the nearest pond, a journey that may be as far as a 1.3 miles
"... the average female bred 1.4 times and produced 8.5 young that survived to metamorphosis per reproductive event, resulting in roughly 12 lifetime metamorphic offspring per female."[24]
California tiger salamanders can live up to 15 years.[citation needed]
