Mammals range in body size from the gigantic blue whale to the tiny Etruscan shrew. Elephants and man may live for nearly one hundred years, while most shrews die before they are three months old. During the past decade, mammalogists and evolutionary biologists have begun to unravel the numerous factors that shape the enormous diversity of mammal life histories. In this volume, leading scientists provide a variety of perspectives on the newest theories in this active field of study. The principle uniting all studies of life history evolution is adaptation by natural selection. The first chapters in the book discuss this topic, offering evolutionary interpretations of geographic variation in mammal life histories, explaining how natural selection operates in fluctuating environments, introducing evolutionary predictions of demographic mathematics, and integrating life histories with behavioral ecology. The next chapters offer functional interpretations of the importance of body size in the life history. Next, several essays explain how developments in quantitative genetics have enabled us to distinguish between genetic and environmental components of variation within and between species. With this as a basis, the chapters that follow draw from principles of natural selection, allometry, and genetics to interpret differences among species of mammals. The book concludes with speculations on various areas where research seems most urgent for the development of a comprehensive understanding of mammal life history evolution. According to the authors, the field is rich with questions, and opportunities abound for both theoretical and empirical research.

This book brings together scientific evidence and experience relevant to the practical conservation of bats. The authors worked with an international group of bat experts and conservationists to develop a global list of interventions that could benefit bats. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bats quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bat conservation actions throughout the world. Bat Conservation is the fifth in a series of Synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)'s Unified Classification of Direct Threats (www.iucnredlist.org/technical-documents/classification-schemes).

Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

"The Biology and Identification of the Coccidia (Apicomplexa) of Rabbits of the World" is a taxonomic summation of a damaging intestinal parasite found in rabbits and transmissible to other species, including humans. This book conceptually and historically summarizes the world's literature on the parasite and also provides a quick guide to isolation procedures, identification, strategies for management, and available chemotherapy. It is a vital source of knowledge about coccidia s real and potential transmission to humans, which can lead to dangerous health problems, like severe dehydration, vomiting, lethargy and even death.

Coccidiosis is an intestinal disease that affects several different animal species, including canines and humans, and is one of the most prevalent protozoal infections in North America. The causative agent is a protozoan that has the ability to multiply rapidly and cause major damage in the intestinal wall, rupturing the cells of the intestinal lining. The final stage, the oocyst, is extremely resistant to environmental stress and is difficult to completely remove from the environment. Oocysts are frequent contaminants of feed and water and when the sporulated oocysts are ingested by other animals, they start the life cycle over in the new host. With the demand for rabbits in scientific research and for rabbit meat for human consumption increasingly globally each year, rabbits are of epidemiologic significance for laboratory workers, university researchers, veterinarians, pet owners, and breeders.
Evaluates the scientific and scholarly merit of each of the publications written about coccidian from every rabbit species, providing a complete historical renditionA treatise for the identification of coccidia and their treatment as neededWritten in a style that can be understood by most educated lay persons and laboratory workersWritten by the first ranked author team among the world-class parasitologists who study coccidiaCombined in one single source, this book follows the gold standards in coccidian biology and identificationBrings all that information together in one volume and solves the problems faced by researchers, veterinarians, students and others in trying to find and navigate through this scattered literature"

Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series will be published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world; this Part 3 is concerned with Western Europe (Britain, Ireland, The Netherlands, Belgium, France, Spain and Portugal). Experts from each country contribute a chapter describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites (also covered in a general chapter), threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climate change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programmes, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will therefore provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.

Why do females in male-philopatric species seem to show larger variation in their life history strategies than males in female-philopatric species? Why did females in human societies come to show enormous variation in the patterns of marriage, residence and mating activities? To tackle these important questions, this book presents the latest knowledge about the dispersing females in male-philopatric non-human primates and in human societies. The non-human primates that are covered include muriquis, spider monkeys, woolly monkeys, gorillas, chimpanzees, bonobos and some species of colobine monkeys. In these non-human primate species females typically leave their natal group before sexual maturation and start reproduction in other groups into which they immigrate. However, there is a large variation as some females may breed in their natal group with some risks of inbreeding with their male relatives and some females may associate with males of multiple groups at the same time after leaving their natal group. Such variation seems to provide better strategies for reproduction depending on local circumstances. Although knowledge about female dispersal patterns and life history is indispensable for understanding the dynamic structure of primate societies, it is still not known how females behave after leaving their natal groups, how many groups they visit before finally settling down and which kinds of groups they choose to immigrate into, due to the large variation and flexibility and the difficulty of tracking females after natal dispersal. To encourage further progress in this important field, this volume provides new insights on evolution of female dispersal by describing factors influencing variations in the dispersal pattern across primates and a hypothesis for the formation of human families from the perspectives of female life history. This book is recommended reading for researchers and students in primatology, anthropology, animal behavior and evolution and for anyone interested in primate societies and human evolution.

For all the love and attention we give dogs, much of what they do remains mysterious. Just think about different behaviors you see at a dog park: We have a good understanding of what it means when dogs wag their tails--but what about when they sniff and roll on a stinky spot? Why do they play tug-of-war with one dog, while showing their bellies to another? Why are some dogs shy, while others are bold? What goes on in dogs' heads and hearts--and how much can we know and understand? Canine Confidential has the answers. Written by award-winning scientist--and lifelong dog lover--Marc Bekoff, it not only brilliantly opens up the world of dog behavior, but also helps us understand how we can make our dogs' lives the best they can possibly be. Rooted in the most up-to-date science on cognition and emotion--fields that have exploded in recent years--Canine Confidential is a wonderfully accessible treasure trove of new information and myth-busting. Peeing, we learn, isn't always marking; grass-eating isn't always an attempt to trigger vomiting; it's okay to hug a dog--on their terms; and so much more. There's still much we don't know, but at the core of the book is the certainty that dogs do have deep emotional lives, and that as their companions we must try to make those lives as rich and fulfilling as possible. It's also clear that we must look at dogs as unique individuals and refrain from talking about "the dog." Bekoff also considers the practical importance of knowing details about dog behavior. He advocates strongly for positive training--there's no need to dominate or shame dogs or to make them live in fear--and the detailed information contained in Canine Confidential has a good deal of significance for dog trainers and teachers. He also suggests that trainers should watch and study dogs in various contexts outside of those in which they are dealing with clients, canine and human, with specific needs. There's nothing in the world as heartwarming as being greeted by your dog at the end of the workday. Read Canine Confidential, and you'll be on the road to making your shared lives as happy, healthy, and rewarding as they can possibly be.

The vertebral spine is a key element of the human anatomy. Its main role is to protect the spinal cord and the main blood vessels. The axial skeleton, with its muscles and joints, provides stability for the attachment of the head, tail and limbs and, at the same time, enables the mobility required for breathing and for locomotion. Despite its great importance, the vertebral spine is often over looked by researchers because: a) vertebrae are fragile in nature, which makes their fossilization a rare event; b) they are metameric (seriated and repeated elements) that make their anatomical determination and, thus, their subsequent study difficult; and c) the plethora of bones and joints involved in every movement or function of the axial skeleton makes the reconstruction of posture, breathing mechanics and locomotion extremely difficult. It is well established that the spine has changed dramatically during human evolution. Spinal curvatures, spinal load transmission, and thoracic shape of bipedal humans are derived among hominoids. Yet, there are many debates as to how and when these changes occurred and to their phylogenetic, functional, and pathological implications. In recent years, renewed interest arose in the axial skeleton. New and exciting finds, mostly from Europe and Africa, as well as new methods for reconstructing the spine, have been introduced to the research community. New methodologies such as Finite Element Analysis, trabecular bone analysis, Geometric Morphometric analysis, and gait analysis have been applied to the spines of primates and humans. These provide a new and refreshing look into the evolution of the spine. Advanced biomechanical research regarding posture, range of motion, stability, and attenuation of the human spine has interesting evolutionary implications. Until now, no book that summarizes the updated research and knowledge regarding spinal evolution in hominoids has been available. The present book explores both these new methodologies and new data, including recent fossil, morphological, biomechanical, and theoretical advances regarding vertebral column evolution. In order to cover all of that data, we divide the book into four parts: 1) the spine of hominoids; 2) the vertebral spine of extinct hominins; 3) ontogeny, biomechanics and pathology of the human spine; and 4) new methodologies of spinal research. These parts complement each other and provide a wide and comprehensive examination of spinal evolution.

This book brings together scientific evidence and experience relevant to the practical conservation of wild birds. The authors worked with an international group of bird experts and conservationists to develop a global list of interventions that could benefit wild birds. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on birds quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bird conservation actions throughout the world. The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.

'Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.' - The Sunday Times, 'Best Books For Summer' 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' - The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They - or, more precisely, we - originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today's 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young - are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their - and our - story.

This is a careful study of obstetrical mechanics in monkeys, apes, and extinct hominids in order to understand the present crisis in human reproduction. Current obstetrical problems have an anthropological origin. Cesarean section, almost unknown at the beginning of the century, is now considered necessary in more than 25% of deliveries. By studying the evolution of anatomical structures and the mode of delivery among other primates, strong reasons are apparent for the present crisis in human labor and delivery. This unique study points the way to further evolution of the human birth process.

The present book is divided into several parts. An introductory chapter serves to make the reader aware of the diversity of the subject of habitat selection in birds. Many if the various aspects of habitat selection introduced in the first chapter are developed in subsequent chapters, and thus it serves to some extent as an overview of the subject and as a "lead-in" to subsequent work.

This is an inspiring tour of the world's oceans and 80 of its most notable inhabitants. Beautifully illustrated, the book includes fascinating stories of the fish, shellfish and other sea life that have somehow impacted human life - whether in our medicine, culture or folklore - in often surprising and unexpected ways.

This is a reprint of the first revision of this classic. Originally published in 1953 as Fishery Bulletin #74 for the US Department of the Interior, Fish and Wildlife Service. The "Gulf of Maine" is defined as an area from the Nantucket Shoals and Cape Cod in the west to Cape Sable in the east. The aim of the book was to provide a handbook for the easy identification of the fishes that occur in the Gulf of Maine, with summaries of what is known about the distribution and relative abundance together with information on the life history of each species. The authors used the 150-fathom boundary as the arbitrary offshore boundary as this will exclude almost all "deep-sea" fishes, which are numerous in the basin of the open Atlantic. Combining information gleaned from the literature as well as surveys from a large number of cruises, the volume covers the Cyclostomes, cartilaginous fishes, torpedoes, skates and rays and the bony fishes. The descriptions are as non-technical as is compatible with scientific accuracy and are limited to external features that will aid in identification in the field.

"Homeostasis and Toxicology of Non-Essential Metals" synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Ag, Al, Cd, Pb, Hg, As, Sr, and U have no known nutritive function in fish at present, but are toxic at fairly low levels.

The companion volume, "Homeostasis and Toxicology of Essential Metals, " Volume 31A, covers metals that are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers.
All major essential metals of interest are covered in metal-specific chaptersEach metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metalA common format is featured throughout this two volume edition
