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.

Available in PDF, EPUB and Kindle. Book excerpt: Oliver P. Pearson’s studies on mammalian biology remain standard reading for ecologists, physiologists, taxonomists, and biogeographers. Reflecting this, the papers gathered here continue to expand our understanding of the ecology and evolution of subterranean mammals, and of ecology, taxonomy, and biogeography of Neotropical mammals, a group that was central to the latter half of Pearson’s career.

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.

Book excerpt: The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

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 The Mammals of Texas written by David J. Schmidly and published by University of Texas Press. This book was released on 2016-08-09 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: From reviews of previous editions: “This is the standard reference about Texas mammals.” —Wildlife Activist “A must for anyone seriously interested in the wildlife of Texas.” —Texas Outdoor Writers Association News “[This book] easily fills the role of both a field guide and a desk reference, and is written in a style that appeals to the professional biologist and amateur naturalist alike. . . . [It] should prove useful to anyone with an interest in the mammal fauna of Texas or the southern Great Plains.” —Prairie Naturalist The Mammals of Texas has been the standard reference since the first edition was coauthored by William B. Davis and Walter P. Taylor in 1947. Revised several times over the succeeding decades, it remains the most authoritative source of information on the mammalian wildlife of Texas, with physical descriptions and life histories for 202 species, abundant photographs and drawings, and distribution maps. In this new edition, David J. Schmidly is joined by one of the most active researchers on Texas mammals, Robert D. Bradley, to provide a thorough update of the taxonomy, distribution, and natural history of all species of wild mammals that inhabit Texas today. Using the most recent advances in molecular biology and in wildlife ecology and management, the authors include the most current information about the scientific nomenclature, taxonomy, and identification of species, while also covering significant advances in natural history and conservation.
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.
