florida gators... never threatened!

If you ain't a Gator, you should be! Alligators (and endangered crocs) are important indicator species atop their food chains, with sensitivity to pollution and pesticides akin to humans. See ESA blawg. Gator blood could be our pharmaceutical future, too. See ESA musing.


Follow the truth.

"This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it." -- Thomas Jefferson to William Roscoe, December 27, 1820.


Thanks, Kevin.

74 Fed. Reg. 18336  / Vol. 74, No. 76 / Wednesday, April 22, 2009 / DEPARTMENT OF THE INTERIOR / Fish and Wildlife Service / 50 CFR Part 17 / Endangered and Threatened Wildlife and Plants; 90-Day Finding on a Petition To List the Tehachapi Slender Salamander (Batrachoseps stebbinsi) as Threatened or Endangered

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list the Tehachapi slender salamander (Batrachoseps stebbinsi) as a threatened or endangered species under the Endangered Species Act of 1973, as amended (Act). We find that the petition presents substantial scientific or commercial information indicating that listing the Tehachapi slender salamander may be warranted. Therefore, with the publication of this notice, we are initiating a status review to determine if listing this species is warranted. To ensure that the status review is comprehensive, we are soliciting information and data regarding this species. We will initiate a determination on critical habitat for this species, if and when we initiate a listing action.

Photos by  Gary Nafis from  According to the petition, the two known populations of the Tehachapi slender salamander, a lungless, skin-breathing species adapted to digging and burrowing underground, may represent separate species, and existing scientific literature reports high levels of differences in coloration, size, and genes between the Caliente Canyon population (pictured above) and the population found in the Tehachapi Mountains (pictured below).  The morphological and genetic differences between the two populations provide evidence that they have been separated for a long time and are likely not interbreeding.
