Download or read book The Amphibians and Reptiles of Costa Rica written by Jay M. Savage and published by University of Chicago Press. This book was released on 2002-08 with total page 1076 pages. Available in PDF, EPUB and Kindle. Book excerpt: World renowned for its biological diversity and model conservation system, Costa Rica is home to a wide variety of amphibians and reptiles, from the golden toad to the scorpion lizard and the black-headed bushmaster. Jay M. Savage has studied these fascinating creatures for more than forty years, and in The Amphibians and Reptiles of Costa Rica he provides the most comprehensive, up-to-date treatment of their biology and evolution ever produced. Savage begins with detailed discussions of the natural and cultural history of Costa Rica, setting the stage for a detailed treatment of each of the 396 species of amphibians and reptiles that may be found there. Each species account synthesizes and analyzes everything that is known about the animal's anatomy, behavior, geographic distribution, systematics, and evolutionary history and provides keys for identifying amphibians and reptiles in the field. In addition to distribution maps and systematic and morphological illustrations, the book includes color photographs of almost every known species, many taken by the distinguished nature photographers Michael and Patricia Fogden. Because Costa Rica has played, and continues to play, a pivotal role in the study of tropical biology as well as in the development of ecotourism and ecoprospecting, and because more than half of the amphibians and reptiles in Costa Rica are also found elsewhere in Central America, The Amphibians and Reptiles of Costa Rica will be an essential book for a wide audience of nature lovers, naturalists, ecotourists, field biologists, conservationists, and government planners.

This book was released on 2017-01-18 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Systematics of the Melanocephala Group of the Colubrid Snake Genus Tantilla The next step of the discrimination analysis involved examination of the material of the various color pattern types for evidence of sym patry or intergradation. No evidence of sympatry was found but evidence of intergradation was and this evidence is used in defining species limits.

Book Synopsis Systematics of North American Colubrid Snakes Related to Tantilla Planiceps (Blainville) by : Charles J. Cole
Download or read book Systematics of North American Colubrid Snakes Related to Tantilla Planiceps (Blainville) written by Charles J. Cole and published by . This book was released on 1981 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Examination of numerous characters (primarily of head coloration, hemipenes, scutellation, and size and proportions) of more than 750 specimens suggests that Tantilla planiceps, as recognized by Tanner (1966), actually represents four distinct species: Tantilla planiceps (Blainville, 1835), of southern California and Baja California; Tantilla yaquia Smith, 1942, of southeastern Arizona and northwestern Mexico; Tantilla atriceps (Günther, 1895), of southern Texas and northeastern Mexico; and Tantilla hobartsmithi Taylor, '1936' (1937), which is broadly distributed in the southwestern United States and northern Mexico and usually has been considered synonymous with T. atriceps. Synonymies, diagnoses, descriptions, illustrations, range maps, and ecological notes are presented for each of these species. Tantilla atriceps and T. hobartsmithi are sibling species with strikingly different hemipenes. They also are the only species of the complex for which sympatry (in Coahuila) has been documented. Future collecting may well demonstrate sympatry at the periphery of the ranges of T. planiceps and T. hobartsmithi and of T. yaquia and T. hobartsmithi. Analysis of variation indicates that some classical taxonomic characters used previously (e.g., number of ventral scales) are not particularly reliable for distinguishing among species of Tantilla. The best specific characters we found are in anatomy of the hemipenes. Variation in hemipenial features usually is correlated with variation in head coloration. Because T. atriceps and T. hobartsmithi are sibling species, now known to differ consistently only in hemipenial characters, and because they exhibit sympatry at the periphery of their ranges, specific identification of females is a problem that requires additional investigation. Once it appeared that male copulatory organs would provide important, diagnostic characters for the four species formerly assigned to T. planiceps, we examined hemipenes on as many specimens (258) as were reasonably available. These included pertinent type-specimens and outgroup comparisons with T. gracilis, T. nigriceps, and T. wilcoxi; hemipenes of these species are distinctive also, and examples of all are described and illustrated (excepting T. wilcoxi). One problem that remains under investigation is the specific relationship between T. atriceps and southern populations of T. nigriceps. No such problem exists between T. hobartsmithi and T. nigriceps, however, as they differ rather consistently in hemipenes and head coloration, and they are sympatric in the western part of the range of T. nigriceps. We also examined maxillary bones, sex ratio, and karyotypes (including that of T. coronata) in addition to the characters mentioned above. Most of these data are not taxonomically useful, due either to lack of significant variation or lack of comparative data from congeners. A preferred cladogram of phylogenetic relationships of T. wilcoxi, T. planiceps, T. yaquia, T. nigriceps, T. atriceps, T. hobartsmithi, and T. gracilis is presented, as is a key to all species of Tantilla known to occur in the western United States and northern Mexico. The most useful characters for distinguishing species of Tantilla, particularly in North America, appear to be in the hemipenes and head coloration. Hereafter, all taxonomic studies within Tantilla routinely should include examination of hemipenes of the specimens examined. When possible, males should be selected as type-specimens"--P. 203.
