Download or read book Avian Evolution written by Gerald Mayr and published by John Wiley & Sons. This book was released on 2016-10-31 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

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 Great Auk Islands a field biologist in the Arctic written by Tim Birkhead and published by A&C Black. This book was released on 2010-10-30 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of the author's research expeditions in the Canadian Arctic, this book is for professional and amateur ornithologists, students in ecology and animal behaviour. The Arctic is one of the world's last great wildernesses: a place of outstanding beauty, history and extraordinary wildlife in which seabirds form an important component of a rich, marine environment. Like many other remote regions, it is under threat from human activities, but to protect it we need to understand it. That understanding can come only through scientific research and the central threat of this book is to examine how such research is actually done. It describes the business of conducting biological studies on seabirds in remote parts of eastern Canada. Several themes are engagingly interwoven: the sheer beauty of the Arctic environment, the intriguing biology of its wildlife, and the discovery and exploitation of enormous seabird colonies, including the destruction of the Great Auk. Tim Birkhead describes in personal detail the different facets of research and brings to life both the difficulties and the excitement of working in the Arctic. What is it like setting up a camp for four months on a remote and uninhabited island not far from the North Pole? How does it feel to commute daily by inflatable boat amidst icebergs to study-areas located on towering cliffs, set between ice-blue glaciers? What do you do when a Polar bear decides that you have invaded its Arctic home? Why are the seabird colonies in the high Arctic so enormous? What do we know about lifestyle of the extinct Great Auk? In 1992 Canada's legendary cod fishery was finally destroyed - what are the consequences of this for other wildlife? These are just a few of the questions dealt with in this book. Our future as a species depends upon science and the understanding it brings of the world we live in. The work of scientists often appears obscure, but in this book, Tim Birkhead has used his experience of seven summers in the Arctic to write an accessible and straightforward account of how research is actually done in the field. The text is enriched by David Quinn's illustrations, and by numerous photographs in both black and white, and colour.
Download or read book Marine Insects written by Lanna Cheng and published by North-Holland. This book was released on 1976 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Download or read book Lagoa Santa Karst Brazil s Iconic Karst Region written by Augusto S. Auler and published by Springer Nature. This book was released on 2020-01-22 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the Lagoa Santa Karst, which has been internationally known since the pioneering studies of the Danish naturalist Peter Lund in the early 1800s. It covers the speleogenesis, geology, vegetation, fauna, hydrogeology, geomorphology, and anthropogenic use of the Lagoa Santa Karst and is the first English-language book on this major karst area. The area, which has been at the heart of the debate on the origin and age of human colonization in the Americas, is characterized by a classical and scenic karst landscape with limestone cliffs, karst lakes and karst plains, in addition to numerous solution dolines. More than 1,000 caves have been documented in the area, many with significant archeological and paleontological value. Despite its great importance, the Lagoa Santa Karst faces severe environmental threats due to limestone mining and the expansion of the metropolis of Belo Horizonte and its surrounding towns. The growing recognition of the area’s remarkable significance has led to increasing concern, and a number of protected areas have now been established, improving the conservation status of this landmark karst area.

Available in PDF, EPUB and Kindle. Book excerpt: More than 99% of all life that has ever existed on this planet is extinct. Moreover, human acceleration of the extinction of species has created a crisis in biodiversity. How can the history of past life be retreived? How does this history bear on our understanding of the organization and evolution of present-day species? These questions are addressed in extinction and phylogeny.
Download or read book Animal Body Size written by Felisa A. Smith and published by University of Chicago Press. This book was released on 2013-08-09 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galileo wrote that “nature cannot produce a horse as large as twenty ordinary horses or a giant ten times taller than an ordinary man unless by miracle or by greatly altering the proportions of his limbs and especially of his bones”—a statement that wonderfully captures a long-standing scientific fascination with body size. Why are organisms the size that they are? And what determines their optimum size? This volume explores animal body size from a macroecological perspective, examining species, populations, and other large groups of animals in order to uncover the patterns and causal mechanisms of body size throughout time and across the globe. The chapters represent diverse scientific perspectives and are divided into two sections. The first includes chapters on insects, snails, birds, bats, and terrestrial mammals and discusses the body size patterns of these various organisms. The second examines some of the factors behind, and consequences of, body size patterns and includes chapters on community assembly, body mass distribution, life history, and the influence of flight on body size.
Download or read book Avian Molecular Evolution and Systematics written by David P. Mindell and published by Academic Press. This book was released on 1997-05-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of DNA and other biological macromolecules has revolutionized systematic studies of evolutionary history. Methods that use sequences of nucleotides and amino acids are now routinely used as data for addressing evolutionary questions that, although not new questions, have defied description and analysis. The world-renowned contributors use these new methods to unravel particular aspects of the evolutionary history of birds. Avian Molecular Evolution and Systematics presents an overview of the theory and application of molecular systematics, focusing on the phylogeny and evolutionary biology of birds. New, developing areas in the phylogeny of birds at multiple taxonomic areas are covered, as well as methods of analysis for molecular data, evolutionary genetics within and between bird populations, and the application of molecular-based phylogenies to broader questions of evolution. - Contains authoritative contributions from leading researchers - Discusses the utility of different molecular markers for questions of avian evolution, involving populations and higher-level taxa - Applies molecular-based phylogenies of birds and molecular population genetics data to broad questions of organismal and molecular evolution. - Compares and contrasts molecular and morphological data sets
Download or read book The Hard Ticks of the World written by Alberto A. Guglielmone and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been designed to summarize current, essential information for every one of the world’s 700+ hard tick species. Under each species name, we will cite the original description, followed by information on type depositories, known stages, distribution (by zoogeographic region and ecoregion), hosts, and human infestation (if any). Each species account will also include a list of salient references and, where necessary, remarks on systematic status. We envision eight chapters: six devoted to the major ixodid tick genera (Amblyomma, Dermacentor, Haemaphysalis, Hyalomma, Ixodes, Rhipicephalus), one covering eight minor genera (including two that are fossil), and a concluding summary chapter. There will be two tables on host associations and zoogeography in each major genus chapter, as well as five tables in the summary chapter, for a total of 17 tables. No similar synopsis of the world’s hard tick species exists in any language.

Download or read book Birds of Stone written by Luis M. Chiappe and published by JHU Press. This book was released on 2016-11-01 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Captivating photographs of the world’s most detailed bird fossils illuminate the early diversity of avifauna. When fossils of birds from China’s Jehol region first appeared in scientific circles, the world took notice. These Mesozoic masterpieces are between 120 and 131 million years old and reveal incredible details that capture the diversity of ancient bird life. Paleontologists all over the world began to collaborate with Chinese colleagues as new and wondrous fossil-related discoveries became regular events. The pages of National Geographic and major scientific journals described the intricate views of feathers as well as food still visible in the guts of these ancient birds. Now, for the first time, a sweeping collection of the most interesting of Jehol’s avian fossils is on display in this beautiful book. Birds of Stone makes visible the unexpected avian diversity that blanketed the earth just a short time (geologically speaking) after a dinosaur lineage gave rise to the first birds. Our visual journey through these fossils is guided by Luis M. Chiappe, a world expert on early birds, and Meng Qingjin, a leading figure in China's natural history museum community. Together, they help us understand the "meaning" of each fossil by providing straightforward narratives that accompany the full-page photographs of the Jehol discoveries. Anyone interested in the history of life—from paleontologists to inquisitive birders—will find Birds of Stone an irresistible feast for the eyes and mind.
