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 Extinctions in Near Time written by Ross D.E. MacPhee and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Near time" -an interval that spans the last 100,000 years or so of earth history-qualifies as a remarkable period for many reasons. From an anthropocentric point of view, the out standing feature of near time is the fact that the evolution, cultural diversification, and glob al spread of Homo sapiens have all occurred within it. From a wider biological perspective, however, the hallmark of near time is better conceived of as being one of enduring, repeat ed loss. The point is important. Despite the sense of uniqueness implicit in phrases like "the biodiversity crisis," meant to convey the notion that the present bout of extinctions is by far the worst endured in recent times, substantial losses have occurred throughout near time. In the majority of cases, these losses occurred when, and only when, people began to ex pand across areas that had never before experienced their presence. Although the explana tion for these correlations in time and space may seem obvious, it is one thing to rhetori cally observe that there is a connection between humans and recent extinctions, and quite another to demonstrate it scientifically. How should this be done? Traditionally, the study of past extinctions has fallen largely to researchers steeped in such disciplines as paleontology, systematics, and paleoecology. The evaluation of future losses, by contrast, has lain almost exclusively within the domain of conservation biolo gists. Now, more than ever, there is opportunity for overlap and sharing of information.

Download or read book Biodiversity of Angola written by Brian J. Huntley and published by Springer. This book was released on 2019-02-20 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Download or read book Techniques in Molecular Systematics and Evolution written by Rob DeSalle and published by Birkhäuser. This book was released on 2013-12-01 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amount of information that can be obtained by using molecular techniques in evolution, systematics and ecology has increased exponentially over the last ten years. The need for more rapid and efficient methods of data acquisition and analysis is growing accordingly. This manual presents some of the most important techniques for data acquisition developed over the last years. The choice and justification of data analysis techniques is also an important and critical aspect of modern phylogenetic and evolutionary analysis and so a considerable part of this volume addresses this important subject. The book is mainly written for students and researchers from evolutionary biology in search for methods to acquire data, but also from molecular biology who might be looking for information on how data are analyzed in an evolutionary context. To aid the user, information on web-located sites is included wherever possible. Approaches that will push the amount of information which systematics will gather in the

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 Osteology of Deinonychus antirrhopus an Unusual Theropod from the Lower Cretaceous of Montana written by John H. Ostrom and published by Yale University Press. This book was released on 2019-01-01 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: John H. Ostrom's expeditions to the Bighorn Basin of Wyoming and Montana in the 1960s resulted in discoveries and research that would change long-held concepts in paleontology. This fiftieth-anniversary edition of his now well-known description of the type specimen of Deinonychus antirrhopus revisits the work that redefined theropod dinosaurs as the intelligent, agile, and gregarious ancestors of modern birds and led in the late twentieth century to a renaissance in the study of dinosaurs and the evolution of flight.

Download or read book Panoan Languages and Linguistics written by David William Fleck and published by . This book was released on 2013 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monographic study of the Panoan family will serve as an invaluable handbook for both Panoanists seeking a broader perspective and scholars who require an introduction to the family. A new classification encompassing all the extant and extinct Panoan languages and dialects, an evaluation of proposed relations to other language families, a detailed history of Panoan linguistics, a typological overview of the phonology and grammar, and a description of ethnolinguistic features in the family combine to provide a complete picture of Panoan languages and linguistics. An index with the synonyms and spelling variants of all the language names and ethnonyms that are or have been claimed to be Panoan will allow for obscure references in the literature to be quickly resolved.

Download or read book Generic Revision and Species Classification of the Microdontinae Diptera Syrphidae written by Menno Reemer and published by PenSoft Publishers LTD. This book was released on 2013-04-12 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hoverflies of the subfamily Microdontinae have a reputation for causing confusion. The adult flies differ so much from other hoverflies that according to some they should be placed in a family of their own. Their diversity in shape and size is astonishing: from large, furry-haired species and convincing wasp-mimics to tiny, unsightly creatures, easily mistaken for something uninteresting. This paper introduces a new generic classification of the Microdontinae. A key to all 43 genera, 7 subgenera and some species groups is presented. All 552 available species names are classified into (sub)genera and species groups. The resulting classification comprises 454 valid species and 98 synonyms, of which 17 valid names and three synonyms are left unplaced. A total number of 26 new species are described, 267 new combinations of species and genera are proposed. The paper concludes with a discussion on diagnostic characters of Microdontinae.

This book was released on 2012-12-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three aviculariine genera endemic to Brazil are revised. Typhochlaena C. L. Koch, 1850 is resurrected, including five species; Pachistopelma Pocock, 1901 includes two species; and Iridopelma Pocock, 1901, six species. Nine species are newly described: Typhochlaena amma sp. n., T. costae sp. n., T. curumim sp. n., T. paschoali sp. n., Pachistopelma bromelicola sp. n., Iridopelma katiae sp. n., I. marcoi sp. n., I. oliveirai sp. n. and I. vanini sp. n. Three new synonymies are established: Avicularia pulchra Mello-Leitão, 1933 and Avicularia recifiensis Struchen & Brändle, 1996 are junior synonyms of Pachistopelma rufonigrum Pocock, 1901 syn. n., and Avicularia palmicola Mello-Leitão, 1945 is a junior synonym of Iridopelma hirsutum Pocock, 1901 syn. n. Pachistopelma concolor Caporiacco, 1947 is transferred to Tapinauchenius Ausserer, 1871, making the new combination Tapinauchenius concolor (Caporiacco, 1947) comb. n. Lectotypes are newly designed for Pachistopelma rufonigrum Pocock, 1901 , Iridopelma hirsutum Pocock, 1901 and Pachistopelma concolor Caporiacco, 1947. Cladistic analyses using both equal and implied weights were carried out with a matrix comprising 62 characters and 38 terminal taxa. The chosen cladogram found with X-Pee-Wee and concavity 6 suggests they are monophyletic. All species are keyed and mapped and information on species habitat and area cladograms are presented. Discussion on biogeography and conservation is provided.

Download or read book Family group Names of Recent Fishes written by Richard Van Der Laan and published by . This book was released on 2014 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Family names are particularly important because they are among the most widely used of all technical animal names. Apart from using the correct family-group name according to the Code, it is also important to use one unique universal name (with a fixed spelling) to avoid confusion. We have compiled a list of familygroup names for Recent fishes, applied the rules of the Code and, if possible, tried to conserve the names in prevailing recent practice. We list all of the family-group names found to date for Recent fishes (N=2625), together with their author(s) and year of publication. This list can be used in assigning the correct family-group name to a genus or a group of genera. With this publication we contribute to the usage of correct, universal family-group names in the classification of, and for communication about, Recent fishes.

Download or read book Systematics of Big eyed Bats Genus Chiroderma Peters 1860 Chiroptera Phyllostomidae written by author 1 and published by . This book was released on 2020 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: We present a revision of the Neotropical bat genus Chiroderma, commonly known as big-eyed bats. Although species of Chiroderma have a wide distribution from western México to southern Brazil, species limits within Chiroderma are not clearly defined, as attested by identification errors in the literature, and there is no comprehensive revision of the genus that includes morphological and molecular data. Our review is based on phylogenetic analyses of two mitochondrial (COI and CYTB) and two nuclear (RAG2 and DBY) genes, coalescence analyses of mitochondrial genes, and morphological analyses including type specimens of all named taxa. We recognize seven species in three clades: the first clade includes (1) C. scopaeum Handley, 1966, endemic to western México and previously considered a subspecies of C. salvini; and (2) C. salvini Dobson, 1878, a taxon associated with montane forests, distributed from México to Bolivia; the second clade includes (3) C. improvisum Baker and Genoways, 1976, endemic to the Lesser Antilles, and (4) C. villosum Peters, 1860, widely distributed on the continental mainland and polytypic, with subspecies C. v. villosum and C. v. jesupi; and the third clade includes (5) the polytypic C. doriae Thomas, 1891, with C. d. doriae distributed in eastern Brazil and Paraguay, and C. d. vizottoi, occurring in northeastern Brazil; (6) C. trinitatum Goodwin, 1958, distributed from Trinidad to Amazonia; and (7) C. gorgasi Handley, 1960, distributed from Honduras to trans-Andean South America, previously considered a subspecies of C. trinitatum.
