Download or read book Taxonomic revision of the olingos Bassaricyon with description of a new species the Olinguito written by Kristofer M. Helgen and published by PenSoft Publishers LTD. This book was released on 2013-08-15 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the first comprehensive taxonomic revision of the olingos, Bassaricyon, based on most available museum specimens, with data derived from anatomy, mitochondrial and nuclear DNA, fieldwork, and geographic range modeling. Olingos are forest-living, arboreal, nocturnal, frugivorous, and solitary, and have one young at a time. Four olingo species can be recognized, including a Central American species (B. gabbii) and lowland species with eastern, cis-Andean (B. alleni) and western, trans-Andean (B. medius) distributions. Surprisingly, the sister lineage to all previously described species of Bassaricyon is an Andean cloud forest species, which we call the Olinguito, that has never been previously described. Bassaricyon neblina sp. n., en-demic to Colombia and Ecuador, is the smallest living member of the family Procyonidae and the first new species of Carnivora named in the American continents in 35 years. We describe four subspecies of Olinguito across the Northern Andes.

Download or read book Conservation Genetics in Mammals written by Jorge Ortega and published by Springer Nature. This book was released on 2020-01-24 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the use of molecular tools to study small populations of rare and endangered mammals, and presents case studies that apply an evolutionary framework to address innovative questions in the emerging field of mammalian conservation genomics using a highly diverse set of novel molecular tools. Novel and more precise molecular technologies now allow experts in the field of mammology to interpret data in a more contextual and empirical fashion and to better describe the evolutionary and ecological processes that are responsible for the patterns they observe. The book also demonstrates how recent advances in genetic/genomic technologies have been applied to assess the impact of environmental/anthropogenic changes on the health of small populations of mammals. It examines a range of issues in the field of mammalian conservation genomics, such as the role that the genetic diversity of the immune system plays in disease protection and local adaptation; the use of noninvasive techniques and genomic banks as a resource for monitoring and restoring populations; the structuring of population by physical barriers; and genetic diversity. Further, by integrating research from a variety of areas – including population genetics, molecular ecology, systematics, and evolutionary and conservation biology – it enables readers to gain a deeper understanding of the conservation biology of mammals that are at increasing risk of extinction at local, regional and global scales. As such, it offers a unique resource for a broad readership interested in the conservation biology of mammals and conservation management strategies to better preserve biodiversity.
Download or read book Seasonally Dry Tropical Forests written by Rodolfo Dirzo and published by Island Press. This book was released on 2012-09-26 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

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 1363 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 New Uses for New Phylogenies written by Paul H. Harvey and published by Oxford University Press on Demand. This book was released on 1996 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in molecular genetics make the sequencing of genes a straightforward exercise. Comparisons of sequenced genes from different individuals of a species, or from different species, allow the construction of family trees or evolutionary trees which reveal genetic relationships. This volume shows for the first time how those trees, or phylogenies, can be used to answer questions about population dynamics, epidemiology, development, biodiversity, conservation, and the evolution of genetic systems. The techniques for deciding what these new trees can tell us come together in a unified framework so that a common set of methods can be applied, whatever area of biology interests the researcher.

Download or read book Tropical Agroecosystems written by John H. Vandermeer and published by CRC Press. This book was released on 2002-12-03 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical areas present ecological, cultural, and political problems that demand analysis that is distinct from general ecological analysis. The tropical environment is special in many ways, from the lack of a biological down season (winter), to generally poor soil conditions, to a reliance on traditional methods of agriculture in an undeveloped society. Presenting a broad range of approaches to agroecosystem analysis, this book addresses specific ecological issues associated with agricultural production, examines two case studies of agricultural transformation and its effect on biodiversity, and discusses key landscape relationships between agroecosystems, wildlife, and human disease.

Download or read book Climate change impacts on twenty major crop pests in Central Asia the Caucasus and Southeastern Europe written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-11-22 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research report for a regional study on the impacts of climate change on the spread of pests contributes to FAO’s normative work, as a milestone for 2020–2021 under the Regular Programme. The year 2020 was designated by the United Nations as the as the International Year of Plant Health (IYPH), with the aim of reducing crop loss from pests, which is estimated at 40 percent. In the current report, agricultural pests as any organism harmful to plants, including viruses, bacteria, fungi, nematodes, insects, etc are defined by the authors. We include those that cause direct damage as well as disease-causing organisms. Climate change is projected to worsen crop losses by another 10–25 percent, which in some regions would emanate from associated pests. Central Asia, the Caucasus and Southeastern Europe are under the research area.
Download or read book Molecular Ecology and Evolution Approaches and Applications written by B. Schierwater and published by Birkhäuser. This book was released on 2013-06-29 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years have witnessed a revolution in the way ecologists and evolutionary biologists approach their disciplines. Modern molecular techniques are now reshaping the spectrum of questions that can be addressed while studying the mechanisms and consequences of the ecology and evolution of living organisms. "Molecular Ecology and Evolution: Approaches and Applications" describes, from a molecular perspective, several methodological and technical approaches used in the fields of ecology, evolution, population biology, molecular systematics, conservation genetics, and development. Modern techniques are introduced, and older, more classic ones refined. The advantages, limitations, and potentials of each are discussed in detail, and thereby illustrate the widening range of cross-field research and applications which this modern technology is stimulating. This book will serve as an important textbook for graduate and advanced undergraduate students, and as a key reference work for researchers
Download or read book Predicting Species Occurrences written by J. Michael Scott and published by Island Press. This book was released on 2002-02 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictions about where different species are, where they are not, and how they move across a landscape or respond to human activities -- if timber is harvested, for instance, or stream flow altered -- are important aspects of the work of wildlife biologists, land managers, and the agencies and policymakers that govern natural resources. Despite the increased use and importance of model predictions, these predictions are seldom tested and have unknown levels of accuracy.Predicting Species Occurrences addresses those concerns, highlighting for managers and researchers the strengths and weaknesses of current approaches, as well as the magnitude of the research required to improve or test predictions of currently used models. The book is an outgrowth of an international symposium held in October 1999 that brought together scientists and researchers at the forefront of efforts to process information about species at different spatial and temporal scales. It is a comprehensive reference that offers an exhaustive treatment of the subject, with 65 chapters by leading experts from around the world that: review the history of the theory and practice of modeling and present a standard terminology examine temporal and spatial scales in terms of their influence on patterns and processes of species distribution offer detailed discussions of state-of-the-art modeling tools and descriptions of methods for assessing model accuracy discuss how to predict species presence and abundance present examples of how spatially explicit data on demographics can provide important information for managers An introductory chapter by Michael A. Huston examines the ecological context in which predictions of species occurrences are made, and a concluding chapter by John A. Wiens offers an insightful review and synthesis of the topics examined along with guidance for future directions and cautions regarding misuse of models. Other contributors include Michael P. Austin, Barry R. Noon, Alan H. Fielding, Michael Goodchild, Brian A. Maurer, John T. Rotenberry, Paul Angermeier, Pierre R. Vernier, and more than a hundred others.Predicting Species Occurrences offers important new information about many of the topics raised in the seminal volume Wildlife 2000 (University of Wisconsin Press, 1986) and will be the standard reference on this subject for years to come. Its state-of-the-art assessment will play a key role in guiding the continued development and application of tools for making accurate predictions and is an indispensable volume for anyone engaged in species management or conservation.
