Download or read book The Timetree of Life written by S. Blair Hedges and published by OUP Oxford. This book was released on 2009-04-23 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrial impacts, and other features. The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routine estimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). They could help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology. This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects of the evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database (www.timetree.net) which allows researchers to both deposit and retrieve data.

Download or read book Reproductive and Developmental Strategies written by Kazuya Kobayashi and published by Springer. This book was released on 2018-06-01 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new insights into the universality of biological systems in animal reproduction and development by a comparative study of a variety of mechanisms in animals ranging from basal invertebrates to vertebrates, including mammals. Animals accomplish genetic diversity through meiosis and fertilization, and during embryogenesis animals must produce specialized cell types, including germ cells, in accordance with their individual body plan. This series of phenomena is essential to the continuity of life in the animal kingdom, and animals show various reproductive and developmental strategies. This volume, comprising four parts, reviews animal kingdom diversity, including reproductive strategies and germ cell differentiation mechanisms (Part 1), sex determination and differentiation (Part2), the mechanisms of fertilization (Part 3), and body axis formation (Part 4). Readers will find descriptions of the reproduction or development of 180 species, 13 phyla, 35 classes, 74 orders, 117 families, and 151 genera in this book. Of particular interest is the diversity of molecules and mechanisms used to achieve the same biological purpose in different animals. Undergraduates, graduate students, and professional scientists who want a deeper understanding of animal reproductive and developmental mechanisms will find this book to be of great value.

Download or read book Conservation Genetics of New World Crocodilians written by Rodrigo Barban Zucoloto and published by Springer Nature. This book was released on 2020-11-09 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to be a comprehensive review of the literature on the conservation genetics of the New World crocodilians, from the biological and demographical aspects of the living species to the application of molecular techniques for conservation purposes. It covers the current status of the molecular genetics applied to phylogenetics, phylogeography, diversity, kinship and mating system, and hybridization, as well its implications for decision making with regards to the conservation of these species at academic and governmental levels. This book can be used as a guide for graduate and undergraduate students to understand how conservation genetics techniques are carried out and how they can help preserve not only crocodilians but also other living species.

Book excerpt: A dichotomous key (that is, one that gives the user only two choices at each level of morphological scrutiny), it is designed for use in college-level herpetology or vertebrate biology courses. It will be especially useful as an effective tool for teaching the principles of taxonomy and for introducing students to the systematics of amphibians and reptiles.

Download or read book A Field Guide to the Reptiles of Thailand written by Tanya Chan-ard and published by Oxford University Press, USA. This book was released on 2015 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thailand is home to over 350 species of reptiles, consisting of many kinds of turtles and tortoises, lizards, snakes and crocodiles. With its extensive network of protected areas, Thailand is one of the richest and most ecologically diverse countries in the world. However, many of these species are being threatened more than ever before, including habitat loss caused by agricultural expansion and intensification, and from wildlife trade. For herpetologists and naturalists, understanding the reptiles of Thailand is now more important than ever before. With A Field Guide to the Reptiles of Thailand, Tanya Chan-ard, John Parr, and Jarujin Nabhitabhata present the definitive resource for identifying and understanding all known species of reptile in the region. It is the only updated and complete guide to the country's reptilian life in existence. The book contains an account of every species, complete with nomenclature, color illustrations, and range maps of known locations. The accounts include discussion of behavior, morphological measurements, and habitat, as well as the most current information on each species' conservation status. The authors explain the current system of classifying the threat level of endangerment, making the presented information and terminology understandable and useful. The introduction to the book discusses the history of herpetology in Thailand, as well as its climate, physiography, and zoogeography. A section on how to use the guide most effectively has also been included to make the book accessible to a wide range of both scientists and nature enthusiasts. A Field Guide to the Reptiles of Thailand is the definitive and most comprehensive resource for herpetologists, naturalists, and conservationists working in Thailand.
