Book Synopsis Handbook of Lizards by : Hobart Smith
Download or read book Handbook of Lizards written by Hobart Smith and published by Cornell University Press. This book was released on 2018-04-11 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough treatment of lizards of the United States and Canada when first published in 1946, Handbook of Lizards has become a landmark among herpetologists and lizard specialists. Hobart M. Smith spent years compiling and organizing information on 136 species of lizards for this classic study. With more than 300 illustrations, including black-and-white photographs, labeled drawings, range maps, and illustrated keys, this volume serves as a still-relevant and convenient reference guide to the study of North American lizards. Darrel Frost, a prominent lizard specialist, provides a foreword for the 1995 paperback edition that underscores the work's relevance for herpetology today. In the first section, Smith covers in concise fashion the habits, life history, habitats, methods of collection and preservation, and structural features of lizards. The second section of the book considers each species under topics that are conveniently arranged for studying both living lizards and laboratory specimens: range, type, locality, size, color, scalation, recognition characters, habitat and habits, and references. Smith also discusses problems for further study and gives recommendations for special investigations of each species. The book concludes with an extensive bibliography.
Book Synopsis EVOLUTION, SYSTEMATICS, BIOGEOGRAPHY, AND CONSERVATION OF DIPLOGLOSSID LIZARDS by : Molly Schools

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on island biodiversity has played an integral part in our understanding of speciation, biogeography, and adaptive radiations. The islands of the Caribbean provide an ideal location to study evolutionary hypotheses because of their proximity to species-rich mainland source areas while being sufficiently isolated to preserve an endemic biota. Most of the more than 1,000 Caribbean reptile and amphibian species occur nowhere else and are typically restricted to a single island. However, anthropogenic pressures resulting in habitat loss and degradation threaten biodiversity, leading to the loss of undescribed and unstudied species. Few studies have been conducted on the phylogenetic relationships and biogeography of Neotropical forest lizards (Diploglossidae) because of the rarity of most species. Before my work, there were 3 recognized genera and 53 species of these lizards, found in Middle America, South America, and on Caribbean islands. I gathered and analyzed sequence DNA of 3,232 genes and 642,775 aligned base pairs in 30 currently recognized diploglossid species and conducted phylogenetic, phylogenomic, biogeographic, ecological, and morphological analyses. I found that Neotropical forest lizards are older and more species-rich than previously thought. Based on this, I described 2 new subfamilies, 4 new genera, and 18 new species. I also resurrected four genera and elevated 17 subspecies to the species level. The family Diploglossidae now contains three subfamilies, 12 genera, and 91 species. I assigned all 59 Caribbean celestine species to IUCN Redlist threat classes, with the primary threats being habitat loss and introduced predators Of these, fifteen species (25%) are Critically Endangered, seventeen species (29%) are Endangered, one species (2%) is Vulnerable, and twenty-six (44%) are Least Concern. Four of the Critically Endangered species are extinct, or possibly extinct. Four of the Critically Endangered species are extinct, or possibly extinct. My biogeographic analyses indicate that forest lizards reached the Caribbean islands by at least two dispersal events, in the Oligocene and Miocene, likely by floating on flotsam from northern South America. Past and present ocean currents facilitated these initial dispersal events and subsequent dispersals among Caribbean islands. Finally, I assigned the species of Neotropical forest lizards to six different ecomorph classes based on ecology, morphology, and statistical analyses. Several of these ecomorphs appear multiple times in my phylogeny, indicating that convergent evolution has occurred within the family.

This book was released on 1931 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Cnemidophorus, one of the largest and most important units within the family Teiidae, is a complex assemblage of species, subspecies and phases, which reaches its maximum diversity in North America. The forms here assigned to this genus occur from southern Brazil to the northern United States, both on the mainland and on the closer neighboring islands, thus comprising one of the most widespread and characteristic groups of lizards of the New World.

Available in PDF, EPUB and Kindle. Book excerpt: Hemiphyllodactylus is a genus of small geckos occurring widely, although uncommonly seen, throughout the Indo-Pacific islands and South Asia. These geckos consist of both bisexual and unisexual species. The unisexual species, Hemiphyllodactylus typus, the most widespread of these geckos, apparently attained its Polynesian to Mascarene distribution (invasion) through accidental human transport. The bisexual species have much smaller distributions, geographically restricted to island groups or limited continental areas. Until the early 1990s, most bisexual populations were considered subspecies of H. typus. In the last two decades, herpetologists have regularly used species epithets proposed for the region under their investigation. This resurrection of species names has occurred largely without explanation or taxonomic study. This study examines the morphology of Hemiphyllodactylus throughout its known range, using 13 regional samples, first examining the differentiation of unisexual and bisexual populations and individuals, then the possibility of regional differentiation among the different bisexual populations. Variation and consistency in morphology in and among the regional sample identify the existence of a wide-ranging unisexual species, H. typus, and at least eight geographically restricted bisexual species. Available museum specimens for some regions are adequate to characterize eight bisexual species, H. aurantiacus, H. ganoklonis n. sp., H. harterti, H. insularis, H. larutensis, H. margarethae, H. titiwangsaensis n. sp., and H. yunnanensis. Potentially unique bisexual populations occur in Hong Kong, southern Indochina, Borneo, and Sri Lanka, but samples are too small to adequately characterize these populations. The origins and evolution of the species are examined, and the study concludes with a taxonomy for the identified species.
Book Synopsis Varanoid Lizards of the World by : Erick Pianka
Download or read book Varanoid Lizards of the World written by Erick Pianka and published by Indiana University Press. This book was released on 2004-09-21 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large and impressive monitor lizard (genus Varanus) has attracted a great deal of interest. Despite being wary and difficult to observe, monitors have received an extraordinary amount of attention from devoted students. Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled the species accounts. In the process of reporting what is known, the book also identifies what remains to be learned about these lizards. This volume stands as a model for showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution.
