The first-and only-authoritative guide to the snakes of Central and Western Africa. Nobody knows exactly how many snake species live in the biodiversity hotspots of Western and Central Africa. While field guides abound that make mammals, birds, and even insects identifiable for residents, travelers, and scientists, half a continent's herpetological richness has remained shrouded in mystery. In a region where nearly 30,000 people die from snake bites every year, even dire medical necessity has been an insufficient inducement for researchers to take on the daunting task of assembling an authoritative list of extant species, let alone a full descriptive record to aid in identification, the essential first step to administering an effective antivenin. The reptiles of Central Africa, particularly, are the most poorly studied in the world, despite their crucial role in the survival of threatened ecosystems. With Snakes of Central and Western Africa, Jean-Philippe Chippaux and Kate Jackson have created a game changer. The result of years of field research and systematic study in the world's leading museums, this book compiles for the first time a comprehensive guide to the region's snakes. Covering a vast swath of the continent, ranging from Mauritania in the northwest to Rwanda in the east and Angola in the south, Chippaux and Jackson provide detailed accounts for the more than 200 species of snakes that inhabit the region. The first part of the book is devoted to the taxonomic characters used for identifying snakes. The authors deal with the evolution and biogeography of African snakes as well as epidemiological and clinical aspects of snakebite. The remaining chapters are organized phylogenetically, following the latest consensus on evolutionary patterns of major snake lineages in sub-Saharan Africa. Species identification is facilitated by simple and accessible dichotomous keys and detailed descriptions of morphological characteristics, complemented by numerous drawings, photos, and distribution maps. Invaluable information on taxonomy and natural history is also included. The book concludes with a comprehensive index and a list of nearly 600 references. Snakes of Central and Western Africa illuminates a previously little-known part of the natural world, provides vital information that could save many lives, and will make an excellent addition to any herpetology library.

The present work evaluates the toxic effects of some environmental stressors on fish eggs and larvae and describes the biomarker responses of fish from locations with varying levels of pollution. Development of the main groups of biomarkers is discussed. The book demonstrates general trends and specific peculiarities of biomarker induction in early fish life and their association with the animal's developmental stages. It addresses responses of fish eggs and larvae to pollution under experimental conditions and presents information obtained from in situ studies. Chapters describe xenobiotics accumulation, anoxia and hypoxia, increasing temperature, eutrophication, and other unfavorable environmental factors, including biotic and abiotic factors, and their impact on fish embryos. They also examine fluctuations in biomarker levels in fish eggs and larvae that have been impacted by climate changes and discuss possible scenarios, especially for fish population size, reproduction, growth, development and biodiversity.

Knowledge of bat echolocation and social calls, and identification using ultrasonic 'bat detectors' and sound analysis software, has grown significantly in the last decade. In this practical guide Jon Russ and contributors (Kate Barlow, Philip Briggs & Sandie Sowler) present the latest information in a clear and concise manner. The book covers topics including the properties of sound, how bats use sound, bat detectors and recording devices, analysis software, and call analysis. For each species found in the British Isles, information is given on distribution, emergence times, flight and foraging behaviour, habitat, echolocation calls including parameters for common measurements, and social calls. Calls are described in the context of the different technologies employed to record them (heterodyne, frequency division and time expansion). Various sonograms for each species are displayed in BatSound and AnaLookW. A species echolocation guide is included.

A guide to birdwatching sites in Trinidad and Tobago: this book shows you where to go and when to visit for the best birding experience. This guide is best used alongside your field guide - it does not include information about identifying birds. All of the sites described in the second edition, along with a host of new ones, have been visited, verified and been given revised or new text. The bar graphs of seasonal distribution and the section on selected species of birds has been updated. Entirely new in this edition are a brief summary of the islands' biota, complete lists of mammals and of amphibians and reptiles. Combined with thorough travel advice and information on local contacts and societies, this exceptionally well organised and rigorous guide is more useful than ever. This is a site guide, not an identification guide.

Chimpanzees, including common chimpanzees and bonobos, are our closest living relatives. This book, which is the first photographic and descriptive musculoskeletal atlas of the genus Pan, adopts the same format as the photographic atlases of Gorilla and Hylobates previously published by the same authors. These three books are part of a series of monographs that will set out the comparative and phylogenetic context of the gross anatomy and evolutionary history of the soft tissue morphology of modern humans and their closest relatives. The atlas, which includes detailed high-quality photographs of musculoskeletal structures from most anatomical regions of the body as well as textual information about the attachments, innervation, function and weight of the respective muscles, is based on dissections of up to 12 chimpanzees and on an extensive review of the literature. It provides an updated review of the anatomical variations within chimpanzees as well as an extensive list of the synonyms used in the literature. The book is designed for students, teachers and researchers studying primatology, comparative anatomy, functional morphology, zoology, and physical anthropology and to medical students, doctors and researchers who are curious about the origin, evolution, homology and variations of the musculoskeletal structures of modern humans.

Rats have long been recognized as a valuable biomedical research model, notably in the investigation of aging, toxicology, addiction, and common human diseases such as diabetes and hypertension. In many instances, individuals conducting such research studies are charged with important responsibilities, including animal facility management, animal husbandry, veterinary care, regulatory compliance, and various experimental methodologies. With the advent of genetic manipulations and biomedical research technological advances such as bioimaging, the versatility and usefulness of the rat as an animal model has soared. The Laboratory Rat, Second Edition captures the multiple advances in this important animal model's husbandry, veterinary care, and experimental methodology. This edition features augmented, expanded, and novel information on biology, anesthesia, analgesia, and experimental techniques benefiting personnel working with rats-from the animal care staff to the researcher and everyone in between. The book is also extremely useful to institutional animal care and use program supporters and elements, including animal care and use committees, institutional officials, occupational health and safety professionals, veterinary technicians, and veterinarians.

“It blew my mind to discover that teenage animals and teenage humans are so similar. Both are naive risk-takers. I loved this book!” —Temple Grandin, author of Animals Make Us Human and Animals in Translation

A revelatory investigation of human and animal adolescence and young adulthood from the New York Times bestselling authors of Zoobiquity.

With Wildhood, Harvard evolutionary biologist Barbara Natterson-Horowitz and award-winning science writer Kathryn Bowers have created an entirely new way of thinking about the crucial, vulnerable, and exhilarating phase of life between childhood and adulthood across the animal kingdom.

In their critically acclaimed bestseller, Zoobiquity, the authors revealed the essential connection between human and animal health. In Wildhood, they turn the same eye-opening, species-spanning lens to adolescent young adult life. Traveling around the world and drawing from their latest research, they find that the same four universal challenges are faced by every adolescent human and animal on earth: how to be safe, how to navigate hierarchy; how to court potential mates; and how to feed oneself. Safety. Status. Sex. Self-reliance. How human and animal adolescents and young adults confront the challenges of wildhood shapes their adult destinies.

Natterson-Horowitz and Bowers illuminate these core challenges through the lives of four animals in the wild: Ursula, a young king penguin; Shrink, a charismatic hyena; Salt, a matriarchal humpback whale; and Slavc, a roaming European wolf. Through their riveting stories—and those of countless others, from adventurous eagles and rambunctious high schooler to inexperienced orcas and naive young soldiers—readers get a vivid and game-changing portrait of adolescent young adults as a horizontal tribe, sharing behaviors and challenges, setbacks and triumphs.

Upending our understanding of everything from risk-taking and anxiety to the origins of privilege and the nature of sexual coercion and consent, Wildhood is a profound and necessary guide to the perilous, thrilling, and universal journey to adulthood on planet earth.

One animal left India in 1515, caged in the hold of a Portuguese ship, and sailed around Africa to Lisbon-the first of its species to see Europe for more than a thousand years. The other crossed the Atlantic from South America to Madrid in 1789, its huge fossilized bones packed in crates, its species unknown. How did Europeans three centuries apart respond to these two mysterious beasts-a rhinoceros, known only from ancient texts, and a nameless monster? As Juan Pimentel explains, the reactions reflect deep intellectual changes but also the enduring power of image and imagination to shape our understanding of the natural world. We know the rhinoceros today as "Durer's Rhinoceros," after the German artist's iconic woodcut. His portrait was inaccurate-Durer never saw the beast and relied on conjecture, aided by a sketch from Lisbon. But the influence of his extraordinary work reflected a steady move away from ancient authority to the dissemination in print of new ideas and images. By the time the megatherium arrived in Spain, that movement had transformed science. When published drawings found their way to Paris, the great zoologist Georges Cuvier correctly deduced that the massive bones must have belonged to an extinct giant sloth. It was a pivotal moment in the discovery of the prehistoric world. The Rhinoceros and the Megatherium offers a penetrating account of two remarkable episodes in the cultural history of science and is itself a vivid example of the scientific imagination at work.

Development agencies have for years been seeking a successful universal response to deprivation. Sparked by controversy and debate, the most recent trend is to look for solutions among 'local' or 'indigenous' populations. Nevertheless, resources continue to be wasted in ill-conceived, centrally-imposed schemes that have not only failed to improve matters in lesser-developed countries but have often made them worse. In such instances it is not local knowledge that is problematic, but development agencies' total misinterpretation of it as just one more 'approach' that can be applied universally. Local knowledge can never be that panacea, because it is not in any sense generic. by illustrating that the potential of local knowledge, in development or elsewhere, can only be achieved through recognition of its essential plurality. Perspectives from leading ethnographers and development professionals on issues such as conservation, agriculture and resource management illustrate that the complexity and cultural specificity of local knowledges can only be accessed via equally diverse theories and methodological approaches. offers ways of advancing the relationship between local knowledge and development, and of furthering anthropology's role in development processes. As a rare example of serious study of local knowledge strategy and its applications, this book illustrates the growing need for real understanding of the issue and its power to assist in positive change.

Laboratory animals, including ferrets, play an important role in biomedical research and advances. The humane care and management of these animals remains an ongoing concern. Published in color to provide greater clarity to the techniques and concepts discussed, The Laboratory Ferret presents basic information and common procedures in detail to provide a quick reference for investigators, technicians, and caretakers in the laboratory setting. The book presents a greater understanding of the use of the ferret in research, such as in studies on influenza. It is a valuable, handy reference for experienced individuals and for those without extensive training in working with ferrets.

Animal welfare is attracting increasing interest worldwide, especially in developed countries where the knowledge and resources are available to (at least potentially) provide better management systems for farm animals, as well as companion, zoo and laboratory animals. The key requirements for adequate food, water, a suitable environment, appropriate companionship and good health are important for animals kept for all of these purposes. There has been increased attention given to farm animal welfare in many co- tries in recent years. This derives largely from the fact that the relentless pursuit of nancial reward and ef ciency, to satisfy market demands, has led to the devel- ment of intensive animal production systems that challenge the conscience of many consumers in those countries. In developing countries, human survival is still a daily uncertainty, so that p- vision for animal welfare has to be balanced against human needs. Animal welfare is usually a priority only if it supports the output of the animal, be it food, work, clothing, sport or companionship. In principle the welfare needs of both humans and animals can be provided for, in both developing and developed countries, if resources are properly husbanded. In reality, however, the inequitable division of the world's riches creates physical and psychological poverty for humans and a- mals alike in many parts of the world.

Sharks in Mexico: Research and Conservation, Volume 85 in the Advances in Marine Biology series, provides in-depth and up-to-date reviews on all aspects of marine biology that will appeal to postgraduates and researchers in marine biology, fisheries science, ecology, zoology and biological oceanography.

Research on the mental abilities of chimpanzees and bonobos has been widely celebrated and used in reconstructions of human evolution. In contrast, scant attention has been paid to the abilities of gorillas and orangutans. This volume aims to complete the picture of hominoid cognition by bringing together the work on gorillas and orangutans and setting it in comparative perspective. This book's introductory chapters set the evolutionary context for comparing cognition in gorillas and orangutans to that of chimpanzees, bonobos, and humans. The remaining chapters focus primarily on the kinds and levels of intelligence displayed by orangutans and gorillas compared to other great apes, including performances in the classic domains of tool use and tool making, imitation, self awareness, social communication, and symbol use.

The preeminent guide to the world's mammals is now enhanced with a dramatically expanded volume covering 19 orders, including such creatures as elephants, armadillos, and manatees. Since its first publication in 1964, Walker's Mammals of the World has become a favorite guide to the natural world for general readers and professionals alike. This new Walker's volume is a completely revised and updated compendium of information on five of the earliest clades to diverge from ancient mammal stock. Uniquely comprehensive in inimitable Walker's style, it incorporates a full account of every genus that has lived in the past 5,000 years. Every named species of each genus is listed in systematic order and accompanied by detailed descriptions of past and present range. This new edition includes * 500+ full-color images throughout * citations to more than 2,200 new references * extensive bioconservation data, with discussion of every species in an IUCN Red List threatened category This volume's thorough updates reflect 20 years of advances in our knowledge of taxonomy, ecology, behavior, life history, and conservation. Substantive changes to 100% of previously existing generic accounts, plus the addition of 17 entirely new generic accounts, double the information in the last edition on the 19 orders covered. The black-and-white illustrations of earlier editions have been replaced by over 500 superb new color images. Remaining true to Ernest P. Walker's vision, the text smoothly combines in-depth scholarship with a popular, readable style to preserve and enhance what the Washington Post called a "landmark of zoological literature."

This monumental, ground-breaking work is the fruit of a lifetime of observation, research and meditation on humans and our closest animal relatives: mammals. The two volumes set out to answer questions such as: -- Are mammals solely the result of random mutation and natural selection essentially external factors or do the internal dynamics of the organism itself play a role in determining their astonishing diversity? -- Why do cattle have horns and deer have antlers? -- Why do small chipmunks have dorsal stripes that run parallel to their spine, and tigers have stripes on their flanks that run parallel to their ribs? Wolfgang Schad demonstrates how such fascinating phenomena can be traced to which organ systems -- nerve-sense, centred in the head; metabolic-limb, centred in the digestive organs and limbs; and circulatory-respiratory, centred in the chest -- are emphasised in a particular species. In this way he establishes the basis for a systematic understanding of mammalian morphology. Schad shows how the different emphases come to expression through a mammal's size, morphology, dentition and coloration, and also in its preferred habit and embryonic development. In almost five decades since its first edition, Wolfgang Schad has continued to add to what has become his life's major work. This expanded edition includes many new insights and additional chapters on antelopes, marsupials, bats, xenarthrans (armadillos, anteaters, and sloths), and pangolins, as well as on milk and mammalian embryology, mammalian embryology and much more. Over 1500 photographs and drawings as well as numerous diagrams illustrate the dynamic relationships between the various families, genera and species. This expanded and updated third edition is presented in a sturdy, handsome slip case. We're delighted that this important work is once again available to readers.

This is the second monograph by the author on biological materials of marine origin. The initial book is dedicated to the biological materials of marine invertebrates. This work is a source of modern knowledge on biomineralization, biomimetics and materials science with respect to marine vertebrates. For the first time in scientific literature the author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad variety of marine vertebrate organisms (fish, reptilian, birds and mammals) and within their unique hierarchically organized structural formations. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures including extinct, extant and living taxa and their biocomposite-based structures from nano- to micro - and macroscale. This monograph reviews the most relevant advances in the marine biological materials research field, pointing out several approaches being introduced and explored by distinct modern laboratories.

Mammalian predators are keystone species in any ecosystem. But many are elusive by nature and have territories that cover large areas of land, which makes them challenging to monitor. When tracks and signs prove difficult to interpret or are non-existent, hair samples recovered from the field offer a fantastic resource – one that is often overlooked. The Hair Scale Identification Guide to Terrestrial Mammalian Carnivores of Canada provides a fully illustrated, up-to-date hair scale reference for all 25 of the terrestrial carnivorous mammals of Canada. From the tiny least weasel (Mustela nivalis) to the giant polar bear (Ursus maritimus), unique traits – as well as tricky similarities – can clearly be observed through hair scale patterns magnified at the medial portion of the hair impression. These scale patterns aid in species identification when hair is the only possible evidence available. This guide also outlines hair impression techniques for samples found in the field, assisting ecologists and technicians with wildlife monitoring studies on predatory mammals where additional identification is required. Including range maps and key identification characteristics for all species represented, as well as superb images of hair scale impressions at two magnification levels, this book is a comprehensive tool for animal hair ID.
