Endangered and Threatened Wildlife and Plants - Northern Mexican Gartersnake and Narrow-headed Gartersnake - Threatened Status (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition) The Law Library presents the complete text of the Endangered and Threatened Wildlife and Plants - Northern Mexican Gartersnake and Narrow-headed Gartersnake - Threatened Status (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition). Updated as of May 29, 2018 We, the U.S. Fish and Wildlife Service (Service), determine threatened species status under the Endangered Species Act of 1973 (Act), as amended, for the northern Mexican gartersnake (Thamnophis eques megalops) and the narrow-headed gartersnake (Thamnophis rufipunctatus), native species from Arizona and New Mexico in the United States. We also finalize a rule under authority of section 4(d) of the Endangered Species Act of 1973, as amended (Act), that provides measures that are necessary and advisable to provide for the conservation of the northern Mexican gartersnake. Both species are listed as threatened throughout their range, which, for the northern Mexican gartersnake, also includes the Mexican states of Sonora, Chihuahua, Durango, Coahuila, Zacatecas, Guanajuato, Nayarit, Hidalgo, Jalisco, San Luis Potosí, Aguascalientes, Tlaxacala, Puebla, México, Veracruz, and Querétaro. The effect of this regulation will be to add these species to the lists of Endangered and Threatened Wildlife and Plants.

The Garter Snakes: Evolution and Ecology is the first comprehensive review of the genus Thamnophis in nearly ninety years. The book includes color plates of all species (many never previously figured in color); extensive discussion of ecology, behavior, and captive care; and a modern key to all species - as well as species-by-species summaries of the systematics and natural history of the thirty different garter snakes now recognized. Of particular interest are the descriptions of lesser-known species in Mexico. Because interest in reptiles has grown dramatically in recent years, this comprehensive guide is designed to appeal to as wide an audience as possible - to both the professional herpetologist interested in the biology of Thamnophis and the hobbyist who wants to know more about these diverse and widespread snakes, both in the home aquarium and in the wild. This up-to-date, appealing book, written by the world's leading authorities, will be extremely useful not only to herpetologists but also to conservationists, ecologists, pet owners, and other readers generally interested in natural history.
Describes the physical characteristics, habitat, and behavior of the common garter snake.
This paper is an attempt to do classification on the garter-snake group to help define differences between natural groups and clarify the systematic arrangements.
