This book was released on 2017-03-28 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fully updated and revised, this is the bestselling comprehensive bilingual identification guide to Mexico’s diverse mammalian fauna. A remarkable achievement that took over 30 years to construct, Keys for Identifying Mexican Mammals is the only complete identification guide to Mexico’s mammalian fauna. Fully updated and revised, this bestselling book follows a bilingual arrangement, with identical information presented in Spanish and English on facing pages. The dichotomous presentation is both easy to follow and flawlessly compiled, including updated and expanded material that surpasses any previously available resource. Hundreds of diagnostic images are dispersed throughout the book, many showing minute details that differentiate one species from another, and introductory materials carefully explain the use of diagnostic features. The heart of the book, though, is the keys themselves, which cover every taxa—from artiodactyls and carnivores to primates and rodents—while allowing confident identification at the species level for both field and museum use. The book closes with appendices that cover preparation of specimens, a glossary, and a bibliography. Anyone with an interest in the mammalian fauna of Mexico, or mammals in general, will find this one-of-a-kind book an indispensable reference to Mexico’s rich diversity of wildlife.

Download or read book Life Underground written by Eileen A. Lacey and published by University of Chicago Press. This book was released on 2000-09 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many mammals like to dig in the dirt, but few call it home. Those that do, such as mole-rats, zokors, and tuco-tucos, have developed novel adaptations to their subterranean life, including bones and muscles modified for efficient digging and ways to "see" underground without using their eyes. These unusual traits, adopted independently by unrelated groups around the world, also make subterranean rodents fascinating subjects for biologists. Life Underground provides the first comprehensive review of the biology of subterranean rodents. Arranged by topic rather than by taxon to facilitate cross-species comparisons, chapters cover such subjects as morphology, physiology, social behavior, genetic variation, and evolutionary diversification. Two main questions run throughout the book. First, to what extent has subterranean life shaped the biology of these animals, leading to similar adaptations among otherwise dissimilar species? Second, how have the distinct evolutionary histories of these groups led to different solutions to the challenges posed by life underground?

Download or read book Latin American Mammalogy written by Michael A. Mares and published by University of Oklahoma Press. This book was released on 1991 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume thirty-six scientists from Latin American and the United States contribute substantially to our knowledge of Latin American mammals. Part 1 provides a history of the pioneers in collection-based mammalogy, which began only about two centuries ago. Chapters in Part 2 demonstrate the search for theories and methodologies that will help us understand how the fauna of this region came to be. Part 3 addresses conservation policy and management in light of recent enormous changes in the natural habitats of Latin America. Part 4 explores the need for conservation-education programs in Latin America as a critical step in the development of a sound land-use ethic. The preface of Latin American Mammalogy, overviews of the four sections, and summaries of the twenty-three chapters are given in Spanish as well as English.
Download or read book The Stockholm Paradigm written by Daniel R. Brooks and published by University of Chicago Press. This book was released on 2019-07-19 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contemporary crisis of emerging disease has been a century and a half in the making. Human, veterinary, and crop health practitioners convinced themselves that disease could be controlled by medicating the sick, vaccinating those at risk, and eradicating the parts of the biosphere responsible for disease transmission. Evolutionary biologists assured themselves that coevolution between pathogens and hosts provided a firewall against disease emergence in new hosts. Most climate scientists made no connection between climate changes and disease. None of these traditional perspectives anticipated the onslaught of emerging infectious diseases confronting humanity today. As this book reveals, a new understanding of the evolution of pathogen-host systems, called the Stockholm Paradigm, explains what is happening. The planet is a minefield of pathogens with preexisting capacities to infect susceptible but unexposed hosts, needing only the opportunity for contact. Climate change has always been the major catalyst for such new opportunities, because it disrupts local ecosystem structure and allows pathogens and hosts to move. Once pathogens expand to new hosts, novel variants may emerge, each with new infection capacities. Mathematical models and real-world examples uniformly support these ideas. Emerging disease is thus one of the greatest climate change–related threats confronting humanity. Even without deadly global catastrophes on the scale of the 1918 Spanish Influenza pandemic, emerging diseases cost humanity more than a trillion dollars per year in treatment and lost productivity. But while time is short, the danger is great, and we are largely unprepared, the Stockholm Paradigm offers hope for managing the crisis. By using the DAMA (document, assess, monitor, act) protocol, we can “anticipate to mitigate” emerging disease, buying time and saving money while we search for more effective ways to cope with this challenge.

Download or read book Ice Age Cave Faunas of North America written by Blaine W. Schubert and published by Indiana University Press. This book was released on 2003-11-10 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the findings of a number of studies on North American cave paleontology. Although not intended to be all-inclusive, Ice Age Cave Faunas of North America contains contributions that range from overviews of the significance of cave fossils to reports about new localities and studies of specific vertebrate groups. These essays describe how cave remains record the evolutionary patterns of organisms and their biogeography, how they can help reconstruct past ecosystems and climatic fluctuations, how they provide an important record of the evolution of modern ecosystems, and even how some of these caves contain traces of human activity. The book's eclectic nature should appeal to students, professional and amateur paleontologists, biologists, geologists, speleologists, and cavers. The contributors are Ticul Alvarez, Joaquin Arroyo-Cabrales, Christopher J. Bell, Larry L. Coats, Jennifer Glennon, Wulf Gose, Frederick Grady, Russell Wm. Graham, Timothy H. Heaton, Carmen J. Jans-Langel, Ernest L. Lundelius, Jr., H. Gregory McDonald, Jim I. Mead, Oscar J. Polaco, Blaine W. Schubert, Holmes A. Semken, Jr., and Alisa J. Winkler.
