The ecological literature on marsupials is dominated by descriptive natural history, and there has hitherto been little attempt at either synthesis or evolutionary interpretation. This book attempts to provide such a synthesis, by drawing on both the descriptive data base and predictions from the burgeoning literature on behavioural and evolutionary ecology. It documents the excellent potential the study of marsupials provides for resolution of theoretical questions of general importance in biology. It does this in three ways. First, by describing the impressive diversity of marsupial life history strategies and trophic roles. Second, by careful comparison with the eutherians, the scope of the marsupial radiation is used to analyse the role of developmental constraints and adaptive radiation in determining the diversification of higher taxa. Lastly, it is suggested that the accessibility of marsupial young during their obligatory pouch life facilitates measurement, manipulation and assessment of kinship not possible in other mammalian groups. Further special topics include marsupial/plant mutualism, marsupial competition and the empirical uses of mammals with simple life histories.

Since the initial description of techniques to immortalize anti body-producing B-lymphocytes by fusion with tissue culture-adapted myeloma cells, methods have been developed to produce monoclonal antibodies of defined specificity in multiple animal species. Stable hybrids can be readily produced in mice using a number of myeloma and hybridoma cell lines. To obviate the problem of identifying fusion partners in other animal species, xenohybrids have been produced using B-lymphocytes from the relevant species and mouse myeloma cells. The use of xenohybrids has minimized the problem of obtain ing stable antibody-producing hybrids in all species examined thus far. Although alternative techniques are being developed to produce monoclonal antibodies by molecular methods, hybridoma technol ogy will remain the technology of choice for producing monoclonal antibodies for a variety of applications in research and industry. The objective of Monoclonal Antibody Protocols is to provide investigators with a set of methods for producing and using mono clonal antibodies in biomedical, agricultural, and biological sciences. The book is not intended to provide methodology for all possible applications, but rather a series of methods presented in an easy-- follow format that can be used by new and established investiga tors, graduate and postgraduate fellows, and technical staff.

This book arrays recent research on the neural and behavioral lateralization of the brain relying heavily on animal modes. The authors employ the comparative method to enhance our understanding of behavior, specifically through hand use and "handedness" by drawing comparisons with studies involving primates. Topics discussed include Patterns of Lateralized Behavior in Prosimians; Behavioral Lateralization in Language-Trained Chimpanzees; Patterns of Handedness: Comparative Study of Nursery School Children and Captive Gorillas; and Rotational Behavior in Children and Adults. It is the first book of its kind devoted entirely to the question of behavioral asymmetries in all primates and thus presents a milestone as it recognizes the accumulating evidence of asymmetry and lateralized behavior in the non-human nervous system.

This examination of a depopulated species, the North American bison, provides insights into the past and present behaviour and ecology of what was once the continent's largest terrestrial mammal. The authors' research, conducted over a five-year period, attempts to resolve such questions as: what happens when only a small proportion of the male of a species mate?; why do animals in particular areas experience morphological malformations?; and how much genetic diversity has been lost since the 19th century? The study also discusses the consequences of mating failures, lineage differences in growth and birth synchrony. It explores behavioural ecology, mate choice, the conservation of ecosystems and the management of endangered species.

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.

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 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).

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.

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

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.

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.

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.

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.

In 2020, it will have been twenty-five years since one of the greatest wildlife conservation and restoration achievements of the twentieth century took place: the reintroduction of wolves to the world's first national park, Yellowstone. Eradicated after the park was established, then absent for seventy years, these iconic carnivores returned to Yellowstone in 1995 when the US government reversed its century-old policy of extermination and--despite some political and cultural opposition--began the reintroduction of forty-one wild wolves from Canada and northwest Montana. In the intervening decades, scientists have studied their myriad behaviors, from predation to mating to wolf-pup play, building a one-of-a-kind field study that has both allowed us to witness how the arrival of top predators can change an entire ecosystem and provided a critical window into impacts on prey, pack composition, and much else. Here, for the first time in a single book, is the incredible story of the wolves' return to Yellowstone National Park as told by the very people responsible for their reintroduction, study, and management. Anchored in what we have learned from Yellowstone, highlighting the unique blend of research techniques that have given us this knowledge, and addressing the major issues that wolves still face today, this book is as wide-ranging and awe-inspiring as the Yellowstone restoration effort itself. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, newly studied behaviors and interactions with other species, and the rippling ecosystem effects wolves have had on Yellowstone's wild and rare landscape. Perhaps most importantly of all, the book also offers solutions to ongoing controversies and debates. Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is a gripping, accessible celebration of the extraordinary Yellowstone Wolf Project--and of the park through which these majestic and important creatures once again roam.

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 remote Gashaka region of north-eastern Nigeria is still largely unexplored. In this premier wilderness, monkeys and apes survive in large numbers -- part of a rich assemblage of wildlife at the interface between the dry sub-Saharan Guinea savannah and the moist Cameroonian highlands. Primates include the rarest chimpanzee subspecies, colobus, guenons and baboons, which thrive here despite the wet climate. The main ethnic groups -- Fulani cattle herders and Hausa speaking subsistence farmers -- still follow age-old traditions. Conservation challenges comprise settlements in protected areas, deforestation, annual fires, livestock grazing and hunting. Primates of Gashaka provides first-hand research accounts in conjunction with the Gashaka Primate Project, founded in 2000. Topics covers primate socioecology; genetics and phylogeography; nutritional ecology; vocal communication and cognition; ethno-botany and ethno-primatology; human subsistence strategies and conflicts with wildlife; as well as habitat surveys assessing success and failure of conservation approaches. The contributions aim for interdisciplinarity and comparative dimensions, across species and the African continent. This pioneering volume about one of the least known iconic primate habitats is of interest to primatologists, anthropologists, policy-makers and conservationists alike.

Ungulates are an extraordinarily important group of animals worldwide, at many levels - in their remarkable biodiversity; in many cases, as keystone species with a disproportionate effect on the functioning of the wider ecological systems of which they form a part or as dominant species acting as ecological engineers; and as a prey base for endangered or expanding populations of large carnivores. They are also important culturally and economically, as a major source of protein in subsistence cultures and because of their wide exploitation in recreational hunting, which is still a major form of land-use in many countries. A number of aspects of the balance of cost and benefit of ungulates and their management in Europe are considered. Through a synthesis of the underlying biology and a comparison of the management techniques adopted in different countries, management approaches which seem effective within their respective circumstances are explored. Each chapter is written by experts in their own particular field, ensuring that they are aware of the most up-to-date literature on that topic and can also offer an experienced and informed review based on their own research experience.

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.

What can the study of young monkeys and apes tell us about the minds of young humans? In this fascinating introduction to the study of primate minds, Juan Carlos Gomez identifies evolutionary resemblances--and differences--between human children and other primates. He argues that primate minds are best understood not as fixed collections of specialized cognitive capacities, but more dynamically, as a range of abilities that can surpass their original adaptations.

In a lively overview of a distinguished body of cognitive developmental research among nonhuman primates, Gomez looks at knowledge of the physical world, causal reasoning (including the chimpanzee-like errors that human children make), and the contentious subjects of ape language, theory of mind, and imitation. Attempts to teach language to chimpanzees, as well as studies of the quality of some primate vocal communication in the wild, make a powerful case that primates have a natural capacity for relatively sophisticated communication, and considerable power to learn when humans teach them.

Gomez concludes that for all cognitive psychology's interest in perception, information-processing, and reasoning, some essential functions of mental life are based on ideas that cannot be explicitly articulated. Nonhuman and human primates alike rely on implicit knowledge. Studying nonhuman primates helps us to understand this perplexing aspect of all primate minds.
