This book examines case studies of North American Quaternary mammalian evolution within the larger domain of modern evolutionary theory. It presents previously unpublished studies of a variety of taxa (xenarthrans, rodents, carnivores, ungulates) examined over several temporal scales, from a few thousand years during the Holocene to millions of years of late Pliocene and Pleistocene time. Different organizational levels are represented, from mosaic population variation, to a synopsis of Quaternary evolution of an entire order (Rodentia). In addition to specific case histories, the book includes purely theoretical and methodological contributions, for example, on the statistical recognition of stasis in the fossil record, new ways to calculate evolutionary rates, and the use of digital image analysis in the study of dental ontogeny. Perhaps the most important aspect of the studies reported in this book is that they span the time between the "ecological moment" and "deep time." Modern taxa can be traced back into the fossil record, and variation among extant taxa can be used as a control against which variation in the extinct ones can be understood.

The North American opossum (Didelphis virginiana) generally is regarded as an important animal, phylogenetically. It is considered to represent a prototype marsupial and closely resembles fossil didelphids (Tyndale-Biscoe 1973). Numerous studies concerning the reproductive biology, embryology, and neurobiology of the opossum have been published. More recently, Didelphis has become popular as an animal model for gastroenterological studies because of the remarkable anatomical and physiological similarities of the esophagus as compared to that of man. Most of the studies of early development have concentrated on early cleavage stages and the formation of the three primary germ layers (Hartman 1916, 1919) and fetal membranes (Selenka 1887; McCrady 1938). The ova of Didelphis remain in the oviduct only for about 24 h before entering the uterus. A corona radiata is absent and each oocyte is surrounded only by a perivitel- line space and a zona pellucida (Talbot and DiCarlantonio 1984). During the short transit period, the egg is fertilized by a single spermatozoon (Rodger and Bedford 1982a,b).

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland-urban interface, a more recent and especially challenging issue

This book describes the basic electrical properties of a variety of mammalian tissues in scientific terms that even a student who has had little formal training in the physics of electricity should find understandable. Familiarity with Ohm's Law is one of the few basic tenets of physics which a reader of this book is assumed to possess. Mathematical treatment is kept to a minimum and formal thermodynamic reasoning is avoided. Instead, reliance is placed upon intuitive ideas of energy with which any undergraduate student of biology who needs to study electric events should feel comfortable.

The woolly spider monkey, or muriqui, is one of the most endangered primate species in the world today. Because of deforestation pressures in its natural habitat-- the Atlantic coastal forests of southeastern Brazil--the muriquis are confined to less than three percent of their original range. There are now only a dozen forest fragments known to support a total muriqui population of about 500 individuals. This book traces the natural history of the muriqui from its scientific discovery in 1806 to its current, highly endangered status. The book provides a case study of this scientifically important primate species by balancing field research and ecological issues. Through Strier's accessible presentation, readers gain a broad understanding of primate behaviour and tropical conservation. The book also gives a practical account of how to set up and pursue an in-depth longitudinal study of an animal population, while describing the excitement of gaining first the muriquis' trust and then insights into their lives. The author offers the unique perspective of a highly committed anthropologist who has devoted years to the observation of this unique species, while working to train students and to protect the muriquis' remaining forest habitats. The book will interest biologists, primatologists, and zoologists, as well as anyone concerned with conservation, ecology, and animal behaviour.

Not since the early 1970s has there been an attempt to describe and illustrate the anatomy of the developing mouse embryo. More than ever such material is needed by biologists as they begin to unravel the molecular mechanisms underlying development and differentiation. After more than ten years of painstaking work, Matt Kaufman has completed The Atlas of Mouse Development--the definitive account of mouse embryology and development.
For all those researching or studying mammalian development, The Atlas of Mouse Development will be the standard reference work for many years to come.
Key Features
* Provides a comprehensive sequential account of the development of the mouse from pre-implantation to term
* Contains clear and concise descriptions of the anatomical features relevant to each stage of development
* Large format for easy use
* Contains explanatory notes and legends, and more than 180 meticulously labeled plates, 1,300 photographs of individual histological sections, and 200 electron micrographs, illustrating:
* Intermittent serial histological sections through embryos throughout embryogenesis and organogenesis
* Differentiation of specific organs and organ systems, including the spinal cord, eyes, gonads, kidneys, lungs and skeletal system
* External appearance of intact embryos throughout development

As our closest relatives in the animal world, monkeys have always fascinated and amused humans in equal measure. Monkeys is an outstanding collection of photographs showing these complex, intelligent animals in their natural habitat. Arranged in chapters covering anatomy, family, behaviour, feeding and young, Monkeys features a wide variety of monkeys and apes, including baboons, gorillas, Orang Utans, macaques, howler monkeys, spider monkeys, marmosets, gibbons, mandrills and chimpanzees. The smallest monkey is the pygmy marmoset, which can be just 117 millimetres (4.6in) in length with a 172-millimetre (6.8in) tail and weighing just over 100 grams (3.5oz); while the massive Grauer's gorilla can weigh over 180 kilos (400lbs). With full captions explaining how the species act in a group, communicate, hunt and feed, and rear its young, Monkeys is a brilliant examination in 230 outstanding colour photographs of these remarkable primates.

The development of the breast-shoulder apparatus in the Marsupialia was inves tigated and compared with the conditions in Monotremata and Placentalia. The results were achieved by the investigation of material comprising altogether 109 histological serial sections of intrauterine embryos, neonates, and pouch young from 11 marsupial species. Additionally, 54 skeletons of subadult and adult marsupials from 25 species were included for comparison. The embryonic states show a strong similarity to the developmental stage of the breast-shoulder apparatus in the monotremes. In contrast, the adult breast-shoulder apparatus generally corresponds to that in placentals. The following elements can be observed in the marsupial breast-shoulder apparatus during embryogenesis: scapula, metacoracoid, procoracoid, first rib, paired sternal elements, unpaired sternal element, and clavicle. All the elements mentioned together form a compact, continuous arch in both the intrauterine embryos and the neonates. In the pouch young, this arch is reduced rather soon after birth, so that a compact connection between the left and the right half of the body no longer exists. All that remains is a loose connection via the clavicle. The metacoracoid becomes the processus coracoideus scapulae. The procoracoid becomes the praeclavium. The unpaired sternal element fuses with the paired sternal element, generating the uniform manubrium sterni. The first rib takes its usual position in the thorax. In the pouch young, the breast shoulder apparatus as a whole already shows all the typical characteristics that can be determined in adults.

Organized under broad ecological headings, this book provides a representative selection of present knowledge of mammal ecology with examples selected from a wide range of species and from all parts of the world.

This revised edition of Bats of Southern and Central Africa builds on the solid foundation of the first edition and supplements the original account of bat species then known to be found in Southern and Central Africa with an additional eight newly described species, bringing the total to 124. The chapters on evolution, biogeography, ecology and echolocation have been updated, citing dozens of recently published papers. The book covers the latest systematic and taxonomic studies, ensuring that the names and relationships of bats in this new edition reflect current scientific knowledge. The species accounts provide descriptions, measurements and diagnostic characters as well as detailed information about the distribution, habitat, roosting habits, foraging ecology and reproduction of each species. The updated species distribution maps are based on 6 100 recorded localities. A special feature of the 2010 publication was the mode of identification of families, genera and species by way of character matrices rather than the more generally used dichotomous keys. Since then these matrices have been tested in the field and, where necessary, slightly altered for this edition. New photographs fill in gaps and updated sonograms aid with bat identification in acoustic surveys. The bibliography, which now contains more than 700 entries, will be an invaluable aid to students and scientists wishing to consult original research.

Mammalian sociobiology is a rapidly advancing field which has made enormous strides in the last ten years. The last major monograph on the subject (Ewer, 1968) was published sixteen years ago, and there is a need for this information to be examined in terms of modern sociobiological theory. My approach throughout is evolutionary and is therefore directed strongly towards research which throws light on the ways in which mammals behave in their natural environments. I have tried to cover as wide a range of mammalian species as possible, although, in some cases, the only data available were obtained from captive individuals. The coverage of this book is not a reflection of the volume of literature published on different species, as I have tried to avoid undue emphasis on the social behaviour of primates and laboratory rodents. I have made scrupulous efforts throughout to avoid an anthropomorphic approach to mammalian behaviour. Terms such as 'strategy', 'evaluation' or 'choice' do not therefore imply conscious planning, but are used neutrally in the way in which they would be applied to a chess-playing computer. In the case of mammals, the programmer was natural selection. While I am fully aware that human beings are mammals, any detailed consideration of human social behaviour lies outside the scope of this book. However, the book may provide a complementary text to those interested in that subject.

Introductions to groups include comparative size illustrations, discussion of behaviors particular to the group, and other unique features.

A useful illustrated glossary of terms and an index of species names complete the guide.

Exquisitely detailed illustrations, stunning photographs, and clearly written text combine to make this an indispensible reference source for marine mammal watchers and anyone interested in the natural world.

Among all the large whales on Earth, the most unusual and least studied is the narwhal, the northernmost whale on the planet and the one most threatened by global warming. Narwhals thrive in the fjords and inlets of northern Canada and Greenland. These elusive whales, whose long tusks were the stuff of medieval European myths and Inuit legends, are uniquely adapted to the Arctic ecosystem and are able to dive below thick sheets of ice to depths of up to 1,500 meters in search of their prey-halibut, cod, and squid. Join Todd McLeish as he travels high above the Arctic circle to meet: Teams of scientific researchers studying the narwhal's life cycle and the mysteries of its tusk Inuit storytellers and hunters Animals that share the narwhals' habitat: walruses, polar bears, bowhead and beluga whales, ivory gulls, and two kinds of seals McLeish consults logbooks kept by whalers and explorers and interviews folklorists and historians to tease out the relationship between the real narwhal and the mythical unicorn. In Colorado, he visits climatologists studying changes in the seasonal cycles of the Arctic ice. From a history of the trade in narwhal tusks to descriptions of narwhals' vocalizations as heard through hydrophones, Narwhals reveals the beauty and thrill of the narwhal and its habitat, and the threat it faces from a rapidly changing world.

Since 2013, an organization called the Nonhuman Rights Project has brought before the New York State courts an unusual request-asking for habeas corpus hearings to determine whether Kiko and Tommy, two captive chimpanzees, should be considered legal persons with the fundamental right to bodily liberty. While the courts have agreed that chimpanzees share emotional, behavioural, and cognitive similarities with humans, they have denied that chimpanzees are persons on superficial and sometimes conflicting grounds. Consequently, Kiko and Tommy remain confined as legal "things" with no rights. The major moral and legal question remains unanswered: are chimpanzees mere "things", as the law currently sees them, or can they be "persons" possessing fundamental rights? In Chimpanzee Rights: The Philosophers' Brief, a group of renowned philosophers considers these questions. Carefully and clearly, they examine the four lines of reasoning the courts have used to deny chimpanzee personhood: species, contract, community, and capacities. None of these, they argue, merits disqualifying chimpanzees from personhood. The authors conclude that when judges face the choice between seeing Kiko and Tommy as things and seeing them as persons-the only options under current law-they should conclude that Kiko and Tommy are persons who should therefore be protected from unlawful confinement "in keeping with the best philosophical standards of rational judgment and ethical standards of justice." Chimpanzee Rights: The Philosophers' Brief-an extended version of the amicus brief submitted to the New York Court of Appeals in Kiko's and Tommy's cases-goes to the heart of fundamental issues concerning animal rights, personhood, and the question of human and nonhuman nature. It is essential reading for anyone interested in these issues.

Mammals of Mexico is the first reference book in English on the more than 500 types of mammal species found in the diverse Mexican habitats, which range from the Sonoran Desert to the Chiapas cloud forests.

Ten years in the making, Mammals of Mexico covers everything from obscure rodents to whales, bats, primates, and wolves. It is thoroughly illustrated with color photographs and meticulous artistic renderings, as well as range maps for each species. Introductory chapters discuss biogeography, conservation, and evolution. The final section of the book illustrates the skulls, jaws, and tracks of Mexico's mammals. This unparalleled collection of scientific information on, and photographs of, Mexican wildlife belongs on the shelf of every mammalogist, in public and academic libraries, and in the hands of anyone curious about Mexico and its wildlife.

The first ethnographic exploration of the contentious debate over whether nonhuman primates are capable of culture In the 1950s, Japanese zoologists took note when a number of macaques invented and passed on new food-washing behaviors within their troop. The discovery opened the door to a startling question: Could animals other than humans share social knowledge-and thus possess culture? The subsequent debate has rocked the scientific world, pitting cultural anthropologists against evolutionary anthropologists, field biologists against experimental psychologists, and scholars from Asia against their colleagues in Europe and North America. In Chimpanzee Culture Wars, the first ethnographic account of the battle, anthropologist Nicolas Langlitz presents first-hand observations gleaned from months spent among primatologists on different sides of the controversy. Langlitz travels across continents, from field stations in the Ivory Coast and Guinea to laboratories in Germany and Japan. As he compares the methods and arguments of the different researchers he meets, he also considers the plight of cultural primatologists as they seek to document chimpanzee cultural diversity during the Anthropocene, an era in which human culture is remaking the planet. How should we understand the chimpanzee culture wars in light of human-caused mass extinctions? Capturing the historical, anthropological, and philosophical nuances of the debate, Chimpanzee Culture Wars takes us on an exhilarating journey into high-tech laboratories and breathtaking wilderness, all in pursuit of an answer to the question of the human-animal divide.

Horses were first domesticated about 6,000 years ago on the vast Eurasian steppe extending from Mongolia to the Carpathian Mountains. Yet only in the last two decades have scientists begun to explore the specific mental capacities of these animals. Responding to a surge of interest in fields from ethology to comparative psychology and evolutionary biology, Michel-Antoine Leblanc presents an encyclopedic synthesis of scientific knowledge about equine behavior and cognition. The Mind of the Horse provides experts and enthusiasts alike with an up-to-date understanding of how horses perceive, think about, and adapt to their physical and social worlds. Much of what we know--or think we know--about "the intelligence of the horse" derives from fragmentary reports and anecdotal evidence. Putting this accumulated wisdom to the test, Leblanc introduces readers to rigorous experimental investigations into how horses make sense of their world under varying conditions. He describes the anatomical and neurophysiological characteristics of the horse's brain, and offers an evolutionary perspective by comparing these features with those of other species. A horseman himself, Leblanc also considers the opinions of renowned riding masters, as well as controversies surrounding the extraordinary powers of the horse's mind that have stirred in equestrian and scientific circles. Although scientists understand more today about how horses think than at any time in our species' long acquaintance with these animals, much remains in the dark. The Mind of the Horse brings together the current state of equine research and will likely stimulate surprising new discoveries.

Infrastructure development in Africa and Asia is expanding at breakneck speed, largely in biodiversity-rich developing nations. The trend reflects governments' efforts to promote economic growth in response to increasing populations, rising consumption rates and persistent inequalities. Large-scale infrastructure development is regularly touted as a way to meet the growing demand for energy, transport and food - and as a key to poverty alleviation. In practice, however, road networks, hydropower dams and 'development corridors' tend to have adverse effects on local populations, natural habitats and biodiversity. Such projects typically weaken the capacity of ecosystems to maintain ecological functions on which wildlife and human communities depend, particularly in the face of climate change. This title is also available as Open Access via Cambridge Core.

A Practical Guide to the Histology of the Mouse provides a full-colour atlas of mouse histology. Mouse models of disease are used extensively in biomedical research with many hundreds of new models being generated each year. Complete phenotypic analysis of all of these models can benefit from histologic review of the tissues. This book is aimed at veterinary and medical pathologists who are unfamiliar with mouse tissues and scientists who wish to evaluate their own mouse models. It provides practical guidance on the collection, sampling and analysis of mouse tissue samples in order to maximize the information that can be gained from these tissues. As well as illustrating the normal microscopic anatomy of the mouse, the book also describes and explains the common anatomic variations, artefacts associated with tissue collection and background lesions to help the scientist to distinguish these changes from experimentally- induced lesions. This will be an essential bench-side companion for researchers and practitioners looking for an accessible and well-illustrated guide to mouse pathology. * Written by experienced pathologists and specifically tailored to the needs of scientists and histologists * Full colour throughout * Provides advice on sampling tissues, necropsy and recording data * Includes common anatomic variations, background lesions and artefacts which will help non-experts understand whether histologic variations seen are part of the normal background or related to their experimental manipulation

The effects of the bone morphogenetic proteins (BMPs) family on bone formation are well documented, but the transforming growth factor (TGF)-beta ( ) isoforms are much less studied. The product of 20 years of study, Induction of Bone Formation in Primates: The Transforming Growth Factor- 3 sums up editor Ugo Ripamonti's research into the osteogenic activity of the three mammalian TGF- isoforms, particularly in primates. It explores how the mammalian TGF- isoforms have the potential to shed light on the apparent redundancy of bone induction signaling. The book unearths the profound and important bone inductive activity of the TGF- 3 isoform. It includes accounts of extensive research in non-human primates from craniofacial tissue regeneration, heterotopic tissue induction, and chapters on periodontal tissue regeneration and synergistic induction of bone formation. It also discusses the future clinical role of the TGF- isoform, including in human studies. This book contributes to the fascinating history of BMP and TGF- research at the intersection of molecular biology, tissue induction, bone regeneration, and craniofacial surgery. It provides a revolutionary awakening to new possibilities in skeletal reconstruction, tissue engineering, and molecular and cellular biology.

A comprehensive account of the origins, evolution, and behavior of South and Central American primates New World Monkeys brings to life the beauty of evolution and biodiversity in action among South and Central American primates, who are now at risk. These tree-dwelling rainforest inhabitants display an unparalleled variety in size, shape, hands, feet, tails, brains, locomotion, feeding, social systems, forms of communication, and mating strategies. Primatologist Alfred Rosenberger, one of the foremost experts on these mammals, explains their fascinating adaptations and how they came about. New World Monkeys provides a dramatic picture of the sixteen living genera of New World monkeys and a fossil record that shows that their ancestors have lived in the same ecological niches for up to 20 million years-only to now find themselves imperiled by the extinction crisis. Rosenberger also challenges the argument that these primates originally came to South America from Africa by floating across the Atlantic on a raft of vegetation some 45 million years ago. He explains that they are more likely to have crossed via a land bridge that once connected Western Europe and Canada at a time when many tropical mammals transferred between the northern continents. Based on the most current findings, New World Monkeys offers the first synthesis of decades of fieldwork and laboratory and museum research conducted by hundreds of scientists.

Erythrocytes of the Rhesus and Cynomolgus Monkeys addresses the morphologic, quantitative, and generative aspects of the erythrocytes of the rhesus monkey Macaca mulatta and the cynomolgus monkey Macaca fascicularis (long-tailed macaque, crab-eating monkey). These two species are the most commonly selected nonhuman primates for basic science and clinical medical investigations. The hemopoietic cells of man and the rhesus monkey display an intimate homogeneity. Their functional activities are close and at times identical. The cynomolgus monkey was enlisted in biomedical studies at a time when rhesus monkeys were not available in sufficient quantities. It has gained increased use in the Far East and in the Western world. It is, for example, employed in the current development of a vaccine against the deadly Ebola virus. The authors of the book discuss the erythropoietic profiles of normal and abnormal macaques of both sexes and of all age groups as investigated with contemporary electronic methodologies. They cover the role of stress as it is perceived by the monkey and how it impacts erythrocellular values, and how to train the monkey to be a cooperative, unperturbed subject for hematologic study. Additional topics include the role of medication in deriving normal physiologic erythrocellular data, the development of the precursors of the erythrocyte (normoblasts), the morphologic analysis of the megaloblastic series of abnormal erythroid cells, the analysis of erythropoiesis in bone marrow, the relationship of the simian immunodeficiency virus and erythropoiesis, erythrocyte life span, and parasitic invasion of the red cell.

The study of the chimpanzee, one of the human species' closest relatives, has led scientists to exciting discoveries about evolution, behavior, and cognition over the past half century. In this book, rising and veteran scholars take a fascinating comparative approach to the culture, behavior, and cognition of both wild and captive chimpanzees. By seeking new perspectives in how the chimpanzee compares to other species, the scientists featured offer a richer understanding of the ways in which chimpanzees' unique experiences shape their behavior. They also demonstrate how different methodologies provide different insights, how various cultural experiences influence our perspectives of chimpanzees, and how different ecologies in which chimpanzees live affect how they express themselves. After a foreword by Jane Goodall, the book features sections that examine chimpanzee life histories and developmental milestones, behavior, methods of study, animal communication, cooperation, communication, and tool use. The book ends with chapters that consider how we can apply contemporary knowledge of chimpanzees to enhance their care and conservation. Collectively, these chapters remind us of the importance of considering the social, ecological, and cognitive context of chimpanzee behavior, and how these contexts shape our comprehension of chimpanzees. Only by leveraging these powerful perspectives do we stand a chance at improving how we understand, care for, and protect this species.
