Download and read online ebook Distributions and Phylogeography of Neotropical Primates write by Marc G. M. Van Roosmalen. This book was released on 2014-01. Distributions and Phylogeography of Neotropical Primates available in PDF, EPUB and Kindle. This is the first complete pictorial field guide to all the known Neotropical Primates/Monkeys of the New World. All taxa are depicted in full color by illustrators Stephen Nash and Piero Gozzaglio according to their phylogeography. Moreover, splash pages containing many, often unique photographs taken by the author of both monkeys in the wild or kept free-ranging in several rehabs/halfway houses run by him over more than 16 years in the rain forest at about 30 km from the city of Manaus-AM, Brazil. Included are also a number of recently identified but not yet published taxa new to science, among which several of the largest-sized Amazonian monkeys (i.e., Ateles, Lagothrix, Chiropotes, Cacajao).

The Neotropics contains the greatest abundance and diversity of primate species of any bio-region in the world. They make up an impressive and varied assemblage of species, from the small pigmy marmoset weighing one hundred grams, to the woolly spider monkey tipping the scale at 10-14 kg. Some in the group, such as the bearded capuchin, show signs of high intelligence evidenced by their use of primitive tools to open nuts and fruit, and many of these species are flagships whose very presence is crucial for the dispersal of seeds and maintenance of primary forests. Unfortunately, a large percentage of Neotropical primate species are threatened or endangered due to various anthropogenic activities including deforestation, illegal hunting, illegal wildlife trade, mining, and road construction. Moreover, there is a general paucity of data of this group because their habitats can be difficult to access and the sheer expansiveness of the Neotropical area. In this book, the authors present new research findings from sixty of the world's leading Neotropical primate scientists in order to bridge this information gap. Specifically, the authors provide up-to-date biological, molecular, conservation, and phylogenic information on many of these poorly understood, yet amazing creatures. It is the authors' intention that this new information will be used as a resource by the novice and professional alike in order to improve society's understanding of Neotropical primates and to help protect them long into the future.

This book was released on 2013-11-10. On the Origin of Allopatric Primate Species and the Principle of Metachromic Bleaching available in PDF, EPUB and Kindle. Here we present a theory on the origin of allopatric primate species that follows - at least in Neotropical primates - the irreversible trend to albinotic skin and coat color, called "metachromic bleaching." It explains why primates constitute such an exceptionally diverse, species-rich, and colorful Order in the Class Mammalia. The theory is in tune with the principle of evolutionary change in tegumentary colors called "metachromism," a hypothesis propounded by the late Philip Hershkovitz. Metachromism holds the evolutionary change in hair, skin, and eye melanins following an orderly and irreversible sequence that ends in loss of pigment becoming albinotic, cream to silvery or white. In about all extant sociable Neotropical monkeys we identified an irreversible trend according to which metachromic varieties depart from the saturated eumelanin (agouti, black or blackish brown) archetypic form and then speciate into allopatric taxa following the trend to albinotic skin and coat color. Speciation goes either along the eumelanin pathway (from gray to silvery to cream to white), or the pheomelanin pathway (from red to orange to yellow to white), or a combination of the two. The theory represents a new evolutionary concept that seems to act indefinitely in a non-adaptive way in the population dynamics of male-hierarchic societies of all sociable primates that act territorial. We have tested the theory in all 17 extant Neotropical monkey genera. Our theory suggests the trend to allopatry among metachromic varieties in a social group or population to be the principal behavioral factor that empowers metachromic processes in sociable Neotropical monkeys. It may well represent the principal mechanism behind speciation, radiation, niche separation, and phylogeography in all sociable primates that hold male-defended territories. We urge field biologists who study primate distributions, demography and phylogeography in the Old World to take our theory to the test in the equally colorful Catarrhini.

Molecular Ecology and Conservation Genetics of Neotropical Mammals available in PDF, EPUB and Kindle. 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 and read online ebook Primate Biogeography write by Shawn M. Lehman. This book was released on 2006-05-24. Primate Biogeography available in PDF, EPUB and Kindle. Primate Biogeography is a subject rarely addressed as a discipline in its own right. This comprehensive source introduces the reader to Primate Biogeography as a discipline. It highlights the many factors that may influence the distribution of primates, and reveals the wide range of approaches that are available to understanding the distribution of this order. The biogeography of primates in the past is a major component of our understanding of their evolutionary history and is an essential component of conservation biology. This book will appeal to primatologists, physical anthropologists, zoologists, and undergraduates in these areas.
