Available in PDF, EPUB and Kindle. Book excerpt: The vast terrain between Panama and Tierra del Fuego contains some of the worlds richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification, distribution, and taxonomy of its mammals. The first such book of its kind, Mammals of South America both summarizes existing information and encourages further research of the mammals indigenous to the region. It includes identification keys and brief descriptions of each order, family, and genus. Species accounts include taxonomic descriptions, synonymies, keys to identification, distributions with maps and a gazetteer of marginal localities, lists of recognized subspecies, brief summaries of natural history information, and discussions of issues related to taxonomic interpretations.
Download or read book Mammals of South America Volume 2 written by James L. Patton and published by University of Chicago Press. This book was released on 2015-03-09 with total page 1392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second installment in a planned three-volume series, this book provides the first substantive review of South American rodents published in over fifty years. Increases in the reach of field research and the variety of field survey methods, the introduction of bioinformatics, and the explosion of molecular-based genetic methodologies have all contributed to the revision of many phylogenetic relationships and to a doubling of the recognized diversity of South American rodents. The largest and most diverse mammalian order on Earth—and an increasingly threatened one—Rodentia is also of great ecological importance, and Rodents is both a timely and exhaustive reference on these ubiquitous creatures. From spiny mice and guinea pigs to the oversized capybara, this book covers all native rodents of South America, the continental islands of Trinidad and Tobago, and the Caribbean Netherlands off the Venezuelan coast. It includes identification keys and descriptions of all genera and species; comments on distribution; maps of localities; discussions of subspecies; and summaries of natural, taxonomic, and nomenclatural history. Rodents also contains a detailed list of cited literature and a separate gazetteer based on confirmed identifications from museum vouchers and the published literature.

Download or read book Phylogenetic Relationships of Oryzomine Rodents Muroidea Sigmodontinae written by Marcelo Weksler and published by . This book was released on 2006 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study I provide a phylogenetic hypothesis for the tribe Oryzomyini that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification. Morphological and molecular data were used for these purposes in combined and separate analyses. Molecular data consisted of partial sequences (1266 bp) from the first exon of the nuclear gene encoding the interphotoreceptor retinoid binding protein (IRBP); the morphological matrix comprised 99 characters, including 16 integumental characters, 32 skull characters, 29 dental characters, 7 postcranial characters, and 10 characters from the phallus and soft-anatomy systems. I present anatomical descriptions for each character, including delineation of different states observed among oryzomyines. Results of the combined analysis were congruent with the IRBP-only dataset for oryzomyine higher-level relationships. Morphological analyses, although showing discrepancies from the combined or IRBP consensus cladograms and with low nodal support values, recovered several clades similar to the combined and IRBP analyses. Systematics of the tribe and the evolution of a few pivotal characters are discussed in light of the proposed phylogeny. Different taxonomic arrangements for species currently included in the genus Oryzomys are suggested. Finally, I evaluate evolutionary and biogeographic hypotheses that are compatible with our current knowledge on oryzomyine relationships.
Download or read book Bones Clones and Biomes written by Bruce D. Patterson and published by University of Chicago Press. This book was released on 2012-05-01 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: As explorers and scientists have known for decades, the Neotropics harbor a fantastic array of our planet’s mammalian diversity, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis. This biological bounty can be attributed partly to the striking diversity of Neotropical landscapes and climates and partly to a series of continental connections that permitted intermittent faunal exchanges with Africa, Antarctica, Australia, and North America. Thus, to comprehend the development of modern Neotropical mammal faunas requires not only mastery of the Neotropics’ substantial diversity, but also knowledge of mammalian lineages and landscapes dating back to the Mesozoic. Bones, Clones, and Biomes offers just that—an exploration of the development and relationships of the modern mammal fauna through a series of studies that encompass the last 100 million years and both Central and South America. This work serves as a complement to more taxonomically driven works, providing for readers the long geologic and biogeographic contexts that undergird the abundance and diversity of Neotropical mammals. Rather than documenting diversity or distribution, this collection traverses the patterns that the distributions and relationships across mammal species convey, bringing together for the first time geology, paleobiology, systematics, mammalogy, and biogeography. Of critical importance is the book’s utility for current conservation and management programs, part of a rapidly rising conservation paleobiology initiative.

With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannahs, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic, which will fascinate both scientists and general readers alike.
Download or read book Evolutionary Relationships among Rodents written by W. Patrick Luckett and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: The order Rodentia is the most abundant and successful group of mammals, and it has been a focal point of attention for compar ative and evolutionary biologists for many years. In addition, rodents are the most commonly used experimental mammals for bio medical research, and they have played a central role in investi gations of the genetic and molecular mechanisms of speciation in mammals. During recent decades, a tremendous amount of new data from various aspects of the biology of living and fossil rodents has been accumulated by specialists from different disciplines, ranging from molecular biology to paleontology. Paradoxically, our understanding of the possible evolutionary relationships among different rodent families, as well as the possible affinities of rodents with other eutherian mammals, has not kept pace with this information "explosion. " This abundance of new biological data has not been incorporated into a broad synthesis of rodent phylo geny, in part because of the difficulty for any single student of rodent evolution to evaluate the phylogenetic significance of new findings from such diverse disciplines as paleontology, embryology, comparative anatomy, molecular biology, and cytogenetics. The origin and subsequent radiation of the order Rodentia were based primarily on the acquisition of a key character complex: specializations of the incisors, cheek teeth, and associated mus culoskeletal features of the jaws and skull for gnawing and chewing.

Available in PDF, EPUB and Kindle. Book excerpt: "In a book both beautifully illustrated and deeply informative, Jonathan Losos, a leader in evolutionary ecology, celebrates and analyzes the diversity of the natural world that the fascinating anoline lizards epitomize. Readers who are drawn to nature by its beauty or its intellectual challenges—or both—will find his book rewarding."—Douglas J. Futuyma, State University of New York, Stony Brook "This book is destined to become a classic. It is scholarly, informative, stimulating, and highly readable, and will inspire a generation of students."—Peter R. Grant, author of How and Why Species Multiply: The Radiation of Darwin's Finches "Anoline lizards experienced a spectacular adaptive radiation in the dynamic landscape of the Caribbean islands. The radiation has extended over a long period of time and has featured separate radiations on the larger islands. Losos, the leading active student of these lizards, presents an integrated and synthetic overview, summarizing the enormous and multidimensional research literature. This engaging book makes a wonderful example of an adaptive radiation accessible to all, and the lavish illustrations, especially the photographs, make the anoles come alive in one's mind."—David Wake, University of California, Berkeley "This magnificent book is a celebration and synthesis of one of the most eventful adaptive radiations known. With disarming prose and personal narrative Jonathan Losos shows how an obsession, beginning at age ten, became a methodology and a research plan that, together with studies by colleagues and predecessors, culminated in many of the principles we now regard as true about the origins and maintenance of biodiversity. This work combines rigorous analysis and glorious natural history in a unique volume that stands with books by the Grants on Darwin's finches among the most informed and engaging accounts ever written on the evolution of a group of organisms in nature."—Dolph Schluter, author of The Ecology of Adaptive Radiation
Download or read book Biogeography and Ecology in South America written by E.J. Fittkau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: With 'Biogeography and Ecology in South America' as the general theme, a total of twenty-nine contributions by thirty authors is offered here in two volumes, being volumes 18 and 19 of the Monographiae Biologicae. Most of these discussions deal with decidedly specialist themes and the editors have been particularly concerned to ensure that the authors enjoyed the greatest possible freedom in the preparation of their work in order that different points of view and interpretations, together with some questions of controversy, may be clarified. This also applies, of course, to the several chapters in which general themes (geographical substance, climate, geology, vegetation, amongst others) are discussed. Since the amount of material available is too great to enable one to aspire to a presentation of the complete biogeographical and ecological picture, this procedure seems expedient. However, these two volumes could well be regarded as being a preparatory work for just such a complete description. Each of the separate technical contributions refers to the continent as a whole, in order to characterise it as such from the viewpoint of the specialist. For this reason it was necessary to forgo special discussions of particular regions or types of landscape, although South America of all places is remarkably rich in unique regional phenom ena, the altiplano of Peru and Bolivia, the relict forests of Fray Jorge, the shrub formations of Tierra del Fuego, the lakes of the High Andes, for example.
Download or read book The Atlantic Forest written by Marcia C. M. Marques and published by Springer Nature. This book was released on 2021-01-13 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Forest is one of the 36 hotspots for biodiversity conservation worldwide. It is a unique, large biome (more than 3000 km in latitude; 2500 in longitude), marked by high biodiversity, high degree of endemic species and, at the same time, extremely threatened. Approximately 70% of the Brazilian population lives in the area of this biome, which makes the conflict between biodiversity conservation and the sustainability of the human population a relevant issue. This book aims to cover: 1) the historical characterization and geographic variation of the biome; 2) the distribution of the diversity of some relevant taxa; 3) the main threats to biodiversity, and 4) possible opportunities to ensure the biodiversity conservation, and the economic and social sustainability. Also, it is hoped that this book can be useful for those involved in the development of public policies aimed at the conservation of this important global biome.
Download or read book Molecular Ecology and Conservation Genetics of Neotropical Mammals written by Maximiliano Nardelli and published by Springer Nature. This book was released on 2021-04-02 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although all living beings modify their environment, human beings have acquired the ability to do so on a superlative space-time scale. As a result of industrialization and the use of new technologies, the anthropogenic impact has been increasing in the last centuries, causing reductions in the sizes or the extinction of numerous wild populations. In this sense, from the field of conservation genetics, various efforts have been made in recent decades to provide new knowledge that contributes to the conservation of populations, species, and habitats. In this book, we summarize the concrete contributions of researchers to the conservation of the Neotropical mammals using Molecular Ecology techniques. The book is divided into three major sections. The first section provides an up-to-date review of the conservation status of Neotropical mammals, the applications of the molecular markers in its conservation, and the use of non-invasive and forensic genetic techniques. The second and third sections present, respectively, a series of case studies in various species or taxonomic groups of Neotropical mammals.

Download or read book How and Why Species Multiply written by Peter R. Grant and published by Princeton University Press. This book was released on 2020-03-31 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Darwin's experiences in the Galápagos Islands in 1835 helped to guide his thoughts toward a revolutionary theory: that species were not fixed but diversified from their ancestors over many generations, and that the driving mechanism of evolutionary change was natural selection. In this concise, accessible book, Peter and Rosemary Grant explain what we have learned about the origin and evolution of new species through the study of the finches made famous by that great scientist: Darwin's finches. Drawing upon their unique observations of finch evolution over a thirty-four-year period, the Grants trace the evolutionary history of fourteen different species from a shared ancestor three million years ago. They show how repeated cycles of speciation involved adaptive change through natural selection on beak size and shape, and divergence in songs. They explain other factors that drive finch evolution, including geographical isolation, which has kept the Galápagos relatively free of competitors and predators; climate change and an increase in the number of islands over the last three million years, which enhanced opportunities for speciation; and flexibility in the early learning of feeding skills, which helped species to exploit new food resources. Throughout, the Grants show how the laboratory tools of developmental biology and molecular genetics can be combined with observations and experiments on birds in the field to gain deeper insights into why the world is so biologically rich and diverse. Written by two preeminent evolutionary biologists, How and Why Species Multiply helps to answer fundamental questions about evolution--in the Galápagos and throughout the world.

Download or read book High Altitude Tropical Biogeography written by François Vuilleumier and published by . This book was released on 1986 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Altitude Tropical Biogeography provides research workers and academics with a comprehensive overview of the biogeography of high tropical mountains, covering the origin, ecology, and evolution of plants and animals of this unique ecological zone. The climate in the high altitude mountain regions of the tropics is cold, resulting in flora and fauna which more closely resemble their counterparts thousand of miles to the north or south than comparable species in the lowland jungles only a few thousand meters below. These ecological "islands", besides being very important to the economies of the tropics, pose interesting questions of physiological adaptation, biogeography, and evolutionary relationships. With contributions from twenty-four international specialists who have devoted years to the study of cold mountain tropics, this book describes some of the most characteristic plant and animal components of the ecosystem. No other book of this scope and content exists on these tropical biotas.
Download or read book New Frontiers of Molecular Epidemiology of Infectious Diseases written by Serge Morand and published by Springer Science & Business Media. This book was released on 2011-09-08 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular epidemiology has recently broaden its focuses due to the development of molecular tools but also by incorporating advances of other fields such as mathematical epidemiology, molecular ecology, population genetics and evolution. Facing new risks of emerging and re-emerging infectious diseases that are threats for humans and their livestock, the objectives of molecular epidemiology include: - the development of molecular tools, genotyping and gene expression - the incorporation of concepts and results of population genetics of infectious diseases - the integration of recent advances in theoretical epidemiology and evolutionary ecology of diseases - a better understanding of transmission for the development of risk factors analyses. This book will demonstrate how the latest developments in molecular tools and in epidemiology can be integrated with studies of host-pathogen interactions. Besides a strong theoretical component, there will also be an emphasis on applications in the fields of epidemiology, public health, veterinary medicine, and health ecology. Students and researchers in the fields of epidemiology, animal and human health, evolutionary ecology, parasitology are the main potential readers of the book, as well as a broader audience from veterinary medicine and conservation.
