Book Description
The non-game wildlife trade poses a risk to our natural landscape, natural heritage, economy, and security. Specifically, the trade in non-game reptiles and amphibians exploits native populations, and is likely not sustainable for many species. Exotic amphibian and reptile species pose risk of invasion and directly or indirectly alter the native landscape. The extent of non-game amphibian and reptile trade is not fully understood and is poorly documented. To quantitatively describe the trade in Texas, I solicited data from the United States Fish and Wildlife Service's (USFWS) Law Enforcement Management Information System (LEMIS) and Texas Parks and Wildlife Department's (TPWD) non-game dealer permits. I surveyed amphibian and reptile pet owners, breeders, Internet sites, pet shops, and meat and seafood establishments by visits, electronic surveys, and observations. The trade in exotic species of amphibians and reptiles in the state of Texas was found to be popular in two ways; the importation of wildlife products and sale of live specimens for pets. Persisting in the pet trade were species known to be exotic, a problem made worse by lack of regulations governing the import, export, and keeping of exotic species. Trade in wild collected native species was primarily for export to foreign countries. Collection of turtles from the wild in Texas was heavy until 2008, when TPWD restricted collection to private waters. Collection of other species from the wild was minimal, with the exception of the Western Diamond-backed Rattlsnake (Crotalus atrox) for rattlesnake roundups. Native species were found to exist in the pet trade, but primarily as genetic color variants that do not occur in the wild, an indication that captive breeding may be relieving pressures on wild caught specimens. Minor changes in reporting requirements and permitting systems at the state and federal level would improve the management of exotic and native amphibians and reptiles that persist in the trade. Changes that include standardized taxonomic reporting requirements at state and federal level, streamlined permitting system for individuals wishing to collect from the wild in Texas, bag limits and seasons for wild collection, increased reporting requirements for owners of exotics, and enforcement of reporting errors would aid in management of exotic and native amphibians and reptiles in the trade.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...Southern and Western Texas, north and east, locally, to Eastland and McLennan Counties. Specimens have been recorded from the following localities: Waco (nine miles north), Midland, Midland County, and Clear Creek, Burnet County (Strecker); San Diego, Helotes, San Angelo, Fort Chadbourne, Menard County, and Desdemonia, Eastland County (Cope), Pecos (Brown), and Rock Springs, Edwards County (Bailey). A living specimen in the Texas Cotton Palace zoo was captured at Hewitt, McLennan County. 124. Hypsiglena Texana Stejneger. Texan Rock Snake. Known from only a few localities in the southern and western sections. Brown mentions one from Seymour, Baylor County. Specimens from San Diego and Laredo are in the National collection. The type was collected by Arthur Schott between Laredo and Camargo, Texas. Cope does not mention this species in his "Crocodilians, Lizards and Snakes of North America," although it was published in 1893, some time before his death. The Texas specimens in the National Museum were listed under the name of H. ochrorhyncha Cope, and texana is not mentioned even as a synonym. Dr. Brown refused to recognize texana as being distinct from ochrorhyncha, claiming that the type must have been an abnormal specimen and the characters assigned by its author of no value. However, as Dr. Stejneger distinctly says that the other specimens from Texas examined by him agree in every respect with the type, I shall here recognize it as a distinct species. 125. Heterodon Platyrhinus Latreille. Spreading Adder: Hog-nosed Snake. The "blowing adder" is distributed over the entire eastern and middle sections west to the foot of the plains and south almost to the Rio Grande River. This species follows the canyons in the...

Book Description
With a wide variety of habitats ranging from southeastern swamps to western deserts, Texas is home to numerous species of frogs, toads, and salamanders. Each area of Texas has a particular set of species that has evolved there over thousands of years. Indeed, most amphibians are not very mobile, and many live their entire lives within a few square meters. This makes them particularly vulnerable to environmental degradation and habitat destruction. Texas Amphibians is the only field guide focused exclusively on the state’s frogs, toads, and salamanders. It presents brief, general accounts of the two orders and fifteen families. Then it identifies each of the seventy-two species in detail, including size, description, voice (if applicable), similar species, distribution (with maps), natural history, reproduction, subspecies (if applicable), and comments and conservation information. Color photographs illustrate the species. The book also includes a general introduction to amphibian natural history, conservation, observation and collection, maintenance in captivity, museum and preserved specimens, and scientific and common names, as well as scientific keys to Texas salamanders and frogs and a generic key to amphibian larvae. This wealth of information, compiled by a team of experts who collectively have over a century of experience in field herpetology, will increase our appreciation for amphibians and the vital role they play as an early indicator of threats to the quality of the environment that we all share.

Dixon's Amphibians and Reptiles of Texas: With Keys, Taxonomic Synopses, Bibliography, and Distribution Maps, completely redesigned throughout with color photographs, revised taxonomic keys, and updated species descriptions, covers more than two hundred species of amphibians and reptiles. As in the previous editions, the book includes an extensive listing of the literature on Texas amphibians and reptiles that goes back to the historic writings of Berlandier, in the early nineteenth century, and is updated to reflect the most recent research.'Comprehensive distribution maps, updated references, and an exhaustive bibliography round out this latest edition of what has come to be widely recognized as the standard scientific guide and reference for professional, academic, and amateur naturalists interested in the herpatofauna of Texas.
