Download or read book South American Sauropodomorph Dinosaurs written by Alejandro Otero and published by Springer Nature. This book was released on 2022-04-25 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sauropodomorpha Huene 1932 is one of the most successful groups of dinosaurs, including the most abundant and diverse herbivorous forms with a worldwide record, extending from the late Triassic to the late Cretaceous. Sauropodomorphs comprise a diverse assemblage of early forms (traditionally called “prosauropods”) and the well-established clade Sauropoda Marsh 1878. Early sauropodomorphs were small to medium sized forms, with long necks and reduced skulls, mostly bipeds and omnivores and were abundant in continental environments in the Late Triassic and Early Jurassic. With more than 150 valid species and a worldwide distribution, Sauropoda includes the dominant herbivorous dinosaurs, from the Middle Jurassic to the Late Cretaceous. Its unique body plan, characterized by gigantic size, graviportal locomotion, long necks and tails, and reduced skulls, made this group an undisputed icon in popular culture since the 19th century. In South America, the sauropodomorph record is particularly rich and abundant, and many species have shed light to understand important milestones in the evolutionary history of this group of dinosaurs. The origin of Sauropodomorpha, the transition to Sauropoda, and the diversification of its most successful evolutionary lineages are largely exemplified by the South American fossil record. In this contribution, we synthetize the diversity of sauropodomorphs from South America, including data on their geographic and stratigraphic provenance, phylogenetics, paleobiology, taphonomy and behaviour, underscoring their significance within the context of sauropodomorph evolution.

Download or read book Naturalised Birds of the World written by Christopher Lever and published by A&C Black. This book was released on 2010-01-29 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book looks at the world's naturalised (successfully introduced) species of bird. Many species have been introduced to countries outside their natural range by people, either deliberately or accidentally, with varied consequences for both those species themselves and the native fauna of their 'new' homes. In Britain, the introduced Canada Goose has quickly become ubiquitous at every lake and riverside, while the Golden Pheasant remains a scarce and unobtrusive inhabitant of a few scattered, remote woodlands. The House Sparrow and Common Starling, both in decline over parts of their native range, are thriving in a naturalised state in North America and elsewhere in the world. Naturalised populations of Mallard in various parts of the world are threatening a total of seven other duck species with extinction through hybridisation. This book discusses each species in turn, describing how, why, when and where its introduction took place, how it became established, and the ecological and economic impacts its presence has had in the country or countries it is naturalised in. Each account has a map, showing natural and introduced range, and there is a wealth of beautiful line drawings of the species concerned.

Book excerpt: The Encyclopedia of Paleontology is designed to address the shortage of general reference works on both vertebrate and invertebrate paleontology and to serve the needs of students and lay persons interested in the field. As the encyclopedia aims to provide basic information, the majority of the 350 entries are devoted to explanations of paleontological concepts and techniques, examinations of the evolutionary development of particular organisms and biological features, profiles of major discoveries, and biographies of leading scientists. Each entry includes an essay and a further reading list. An international team of 200 leading experts in the field has prepared the illustrations and the essays, which range from concise descriptions to comprehensive discussions.

Download or read book Mammals of the Southeastern United States written by Troy L. Best and published by University Alabama Press. This book was released on 2020-08-25 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: First comprehensive account of the mammals of the entire southeastern US The southeastern United States is home to a remarkable and diverse mammalian fauna that is a significant part of the region’s rich natural heritage. Mammals of the Southeastern United States presents accounts of 137 species that currently or previously occurred in the Southeast. Although accessible and useful for the generalist, this book provides an up-to-date compilation of basic knowledge about native and nonnative mammals of the region that is suitable for students of all ages and for professional mammalogists and biologists alike. This volume profiles common species like the eastern gray squirrel, the white-tailed deer, and the Virginia opossum, but also includes among its accounts many extant species, such as the jaguar and porcupine, that once occurred in the region; native species, like the Caribbean monk seal, that are now extinct; native species that have been extirpated, or wiped out, from all or part of the region, such as the red wolf, cougar, American bison, and elk; and many introduced species, including the Mexican mouse opossum, common squirrel monkey, and capybara. Each species account includes full-color images of the animal, plates featuring at least three views of its skull, color distribution maps of its approximate geographic range in the Southeast and in North America, and an up-to-date synthesis of several aspects of its biology, including habitat, diet, predators, parasites, diseases, and behaviors. An introductory chapter on conservation summarizes the current status of mammalian populations in the region and provides insight into some of the threats mammals now encounter in the Southeast.

Available in PDF, EPUB and Kindle. Book excerpt: With more than 10,000 known species, recent reptiles (excluding birds) are the most specious tetrapod class. Their diversity is high, and many of them are frequently used as model organisms in phylogeographic and ecological studies. On the other hand, unique aspects of their biology are still being studied and important contributions to their understanding have just been issued. These aspects include the evolution of viviparity and of venom glands, metabolic regulation in poikilotherms, their ecophysiological tolerance and neurobiological and sensorial capacities such as infrared imaging and chemosensitivity. Genetic and developmental phenomena such as parthenogenesis and temperature-dependent sex determination are also special to reptiles. They are generally important for understanding evolutionary processes in vertebrates. The latest results of worldwide research on dinosaurs and other fossil reptiles, crocodiles and turtles conclude this first volume of Reptilia in the Handbook of Zoology.

Book excerpt: Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

Download or read book Naturalized Reptiles and Amphibians of the World written by Christopher Lever and published by . This book was released on 2003 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency--either accidentally or deliberately--and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by and independent of mankind.
