Ambystoma leorae (Leora's Stream Salamander)

Synonyms: Rhyacosiredon leorae

Wikipedia Abstract

The Leora's stream salamander or Ajolote (Ambystoma leorae) is a rare species of mole salamander in the Ambystomatidae family. It is endemic to a very small area of land in the Iztaccihuatl-Popocatepetl National Park on the border of the State of Mexico with Puebla, with a single known population on Mount Tlaloc. Its very specific requirements as regards water quality mitigates against its survival in a habitat where water is being extracted, cattle graze and the salamander has traditionally been eaten as food. It has been listed as a threatened species by the Mexican Government and as "critically endangered" by the International Union for Conservation of Nature.

EDGE Analysis

The family Ambystomatidae or “the mole salamanders” diverged from all other salamanders in the Early Cretaceous period over 140 million years ago, around five million years before the koala and dolphin lineages diverged from their common ancestor. The small number of species that represent the genus Ambystoma are highly evolutionarily distinct members of both the salamanders and the amphibians as a whole. Leora’s Stream Salamander appears to be confined to the upper tributaries of the Balsas River, central Mexico. Conservation and restoration of this habitat is an urgent priority in order to save this species from extinction in the future.
