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.

75 Fed. Reg. 66482 / Vol. 75, No. 208 / Thursday, October 28, 2010 / Proposed Rules
DEPARTMENT OF THE INTERIOR / Fish and Wildlife Service
50 CFR Part 17 / Docket No. FWS–R2–ES–2010–0072; MO 92210–0–0009–B4 /RIN 1018–AX17
Endangered and Threatened Wildlife and Plants; Endangered Status and Designation of Critical Habitat for Spikedace and Loach Minnow
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to change the status of spikedace (Meda fulgida) and loach minnow (Tiaroga cobitis) from threatened to endangered under the Endangered Species Act of 1973, as amended, and to designate critical habitat for both species. In total, we are proposing approximately 1,168 kilometers (726 mi) of streams as critical habitat for spikedace, and 1,141 kilometers (709 miles) of streams as critical habitat for loach minnow. The proposed critical habitat is located in Apache, Cochise, Gila, Graham, Greenlee, Navajo, Pima, Pinal, and Yavapai Counties, Arizona, and Catron, Grant, and Hidalgo Counties in New Mexico. DATES: We will consider comments received or postmarked on or before December 27, 2010. We must  receive requests for public hearings, in writing, at the address shown in the FOR FURTHER INFORMATION CONTACT section by December 13, 2010.

The spikedace is a member of the minnow family Cyprinidae, and is the only species in the genus Meda. The spikedace was first collected from the San Pedro River in 1851. The spikedace is a small, slim fish less than 75 millimeters (mm) (3 inches (in)) in length. Spikedace have olive-gray to brownish skin, with silvery sides and vertically elongated black specks. Spikedace have spines in the dorsal fin. Spikedace are found in moderate to large perennial streams, where they inhabit shallow riffles (those shallow portions of the stream with rougher, choppy water) with sand, gravel, and rubble substrates.
