This book was released on 1999 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 32 papers collected herein reflect the great diversity and interest that the study of fossil birds has generated in recent years. The first seven papers (Mourer-Chauvir et al., Worthy and Jouventin, Segu and Alcover, Steadman and Hilgartner, Millener, Worthy, Pavia) relate to late Quaternary birds from islands, where human intervention in the last few thousand years has caused many heretofore unrecorded extinctions. Three papers on Quaternary avifaunas of continental Europe deal with distributional changes and cultural use of birds by humans in Siberia (Potapova and Panteleyev), the utility of patterns of seabird distribution in determining former marine climatic conditions (Tyrberg), and temporal changes in morphology of ptarmigans (Lagopus) through the late Pleistocene (Stewart). Three papers deal with late Cenozoic raptors (Campbell et al., Tambussi and Noriega, Emslie and Czaplewski). New genera from Paleogene deposits are described by Boles and Ivison, Karhu, and Peters. Five papers deal with ancient waterfowl. Alvarenga describes the first fossil screamer (Anhimidae) from the Oligocene of Brazil. Olson provides the first fossil records of the Anseranatidae, with the description of a new species from the early Eocene of England, which is referred to Anatalavis from the Paleocene/Cretaceous of New Jersey. Ericson provides the means to distiguish Eocene fossils of the duck-like Presbyornis from the flamingo-like Juncitarsus and gives new records of the latter. Benson shows that the Paleocene Presbyornis isoni once ranged from Maryland to North Dakota, and he gives records of other Paleocene birds from North Dakota. Hope names a new, larger species of Graculavus, extending the range of the genus from New Jersey to the Cretaceous of Wyoming.The early history and evolution of birds receives great attention. Dzerzhinsky expands upon the significance of cranial morphology in paleognathous birds. Kurochkin relates the early Cretaceous genus Ambiortus to the Chinese Otogornis, which are supposed to be on a line with modern birds, as opposed to the Enantiornithes. Bochenski uses paleogeography to suggest that the Enantiornithes must antedate Archaeopteryx. Zhou and Martin show that the manus of Archaeopteryx is more bird-like than previously realized. Martin and Stewart use bird teeth to argue against dinosaurian origins for Aves, whereas Elzanowski diverges on various aspects of dinosaurian cranial morphology and that of early birds that may have evolutionary significance. Witmer, Chiappe, and Goslow present summaries of three sessions of a roundtable discussion on avian origins, early evolution of birds, and the origins of flight, which was held on June 7, the last day of the meeting, and which covered much controversial territory.
Download or read book Paleogene Fossil Birds written by Gerald Mayr and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present book the Paleogene fossil record of birds is detailed for the first time on a worldwide scale. I have developed the idea for such a project for several years, and think that it is an appropriate moment to present a summary of our c- rent knowledge of the early evolution of modern birds. Meanwhile not only is there a confusing diversity of fossil taxa, but also significant progress has been made concerning an understanding of the higher-level phylogeny of extant birds. Hypotheses which were not considered even a decade ago are now well supported by independent analyses of different data. In several cases these group together morphologically very different avian groups and allow a better understanding of the mosaic character distribution found in Paleogene fossil birds. The book aims at bringing some of this information together, and many of the following data are based on first-hand examination of fossil specimens.
Download or read book Holocene Extinctions written by Samuel T. Turvey and published by OUP Oxford. This book was released on 2009-05-28 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extent to which human activity has influenced species extinctions during the recent prehistoric past remains controversial due to other factors such as climatic fluctuations and a general lack of data. However, the Holocene (the geological interval spanning the last 11,500 years from the end of the last glaciation) has witnessed massive levels of extinctions that have continued into the modern historical era, but in a context of only relatively minor climatic fluctuations. This makes a detailed consideration of these extinctions a useful system for investigating the impacts of human activity over time. Holocene Extinctions describes and analyses the range of global extinction events which have occurred during this key time period, as well as their relationship to both earlier and ongoing species losses. By integrating information from fields as diverse as zoology, ecology, palaeontology, archaeology and geography, and by incorporating data from a broad range of taxonomic groups and ecosystems, this novel text provides a fascinating insight into human impacts on global extinction rates, both past and present. This truly interdisciplinary book is suitable for both graduate students and researchers in these varied fields. It will also be of value and use to policy-makers and conservation professionals since it provides valuable guidance on how to apply lessons from the past to prevent future biodiversity loss and inform modern conservation planning.
Download or read book Vanished and Vanishing Parrots written by Joseph Forshaw and published by CSIRO PUBLISHING. This book was released on 2017-10-02 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joseph M. Forshaw, one of the world’s leading authorities on parrots, calls attention to the threats they face: they are one of the most endangered groups of birds, with a growing number of species nearing extinction. The main threats arise from habitat loss through deforestation and agricultural development and from the taking of birds for the international live-bird trade. Vanished and Vanishing Parrots brings together information on species that have become extinct in historical times with information on species that are in danger of becoming extinct to increase public awareness of the plight of these magnificent birds. Vivid colour plates by the wildlife artist Frank Knight draw attention to the spectacular species that we have lost or that could be lost. Forshaw’s work gives us fascinating insight into these endangered and extinct parrots. Vanished and Vanishing Parrots will be a valuable reference for scientific, ornithological and avicultural organisations, as well as individual lovers of birds and of illustrated natural history books.
Download or read book The Great Basin written by Donald Grayson and published by Univ of California Press. This book was released on 2011-04-18 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Great Basin, centering on Nevada and including substantial parts of California, Oregon, and Utah, gets its name from the fact that none of its rivers or streams flow to the sea. This book synthesizes the past 25,000 years of the natural history of this vast region. It explores the extinct animals that lived in the Great Basin during the Ice Age and recounts the rise and fall of the massive Ice Age lakes that existed here. It explains why trees once grew 13' beneath what is now the surface of Lake Tahoe, explores the nearly two dozen Great Basin mountain ranges that once held substantial glaciers, and tells the remarkable story of how pinyon pine came to cover some 17,000,000 acres of the Great Basin in the relatively recent past. These discussions culminate with the impressive history of the prehistoric people of the Great Basin, a history that shows how human societies dealt with nearly 13,000 years of climate change on this often-challenging landscape"--Provided by publisher.

Available in PDF, EPUB and Kindle. Book excerpt: "Mesozoic Birds is the first book to bring together world-renowned specialists on fossil birds and their importance to avian origins and, more importantly, it stresses a unified approach (cladistics) and presents the most anatomically detailed analyses available to date. No other study or collection of studies has ever done so much. How could the project not be welcomed by its audience of paleontologists, ornithologists, and evolutionary biologists!"—David Weishampel, editor of The Dinosauria "This is the first comprehensive volume dedicated to the relationships and evolution of the birds that lived during the Age of Dinosaurs. Its wealth of information and its diversity of viewpoints will ensure that this indispensable volume is used and discussed for many years to come."—Kevin Padian, University of California, Berkeley
