This volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of the skin and digits of the birds, and the potential welfare implications of industry practices on these structures. Each chapter in this volume focuses on a particular aspect of the commercial farming of ratites with contributing authors from a broad range of disciplines.

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so. Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is ubiquitous in fish. Overexploitation by capture fisheries does not disrupt sex differentiation but crowding in aqua-farms does, by reducing accessibility to food supply. Some of the man-made chemicals routinely used worldwide mimic endogenous hormones. For example endosulfan, which is widely used in developing countries, disrupts endogenous hormones and feminizes fish. For the first time, this book views endocrine disruption from the point of labile early life and non-labile adult stages. It shows that sex can irreversibly be reversed, when exposed to endocrine disrupting chemicals (EDCs) during early labile stages but reversibly impairs reproductive output on exposure to EDCs during non-labile adult stage. A consequence of climate change, elevated temperature, and declining oxygen and pH levels is that it masculinises genetic female fish. Fish display a remarkable ability to postpone the labile period. Besides postponement, some primary and tertiary gonochores have two distinct labile periods amenable to temperature and hormonal manipulations. Hermaphrodites have retained the period until the end of the adult stage and are capable of sex change/reversal more than once in both male and female directions.

Previous experimental research has suggested that chimpanzees may understand some of the epitemological aspects of visual perception, such as how the perceptual act of seeing can have internal mental consequences for an individual's state of knowledge. Other research suggests that chimpanzees and other nonhuman primates may understand visual perception at a simpler level; that is, they may at least understand seeing as a mental event that subjectively anchors organisms to the external world. However, these results are ambiguous and are open to several interpretations. In this Monograph, we report the results of 15 studies that were conducted with chimpanzees and preschool children to explore their knowledge about visual perception.

This monograph presents the results of over 10 years of paleontological and geological survey in the Baynunah Formation of the United Arab Emirates. Exposed widely in western Abu Dhabi Emirate, the Baynunah Formation and its fossils provide the only record of terrestrial environments and evolution in the Arabian Peninsula during the late Miocene epoch (12-5 Ma). This volume describes new fossils collected since 2002, presented systematically by taxon, and including mammals, reptiles, and invertebrates, as well as fossil trackways. The discoveries are framed within the results of new geological, geochemical, and geochrononological analyses, providing an updated and synthetic view of the age, environments, and biogeographic relationships of this important fossil assemblage.

From the bald eagle to the pileolated woodpecker, the varied and abundant birdlife of the northwestern national parks is as impressive as the parks' dramatic scenery. To help both beginning and advanced birders make the most of their visits to these parks, Roland Wauer has written this finding guide, which introduces the most common birds and the most likely places to see them.

The book opens with practical advice on getting started in birding--choosing binoculars, bird identification, proper field techniques, etc. Then after a concise discussion of the national parks as "islands" of bird habitat, the succeeding chapters fully describe each park, including its plant and animal communities and the facilities and interpretive activities available to visitors. Wauer takes readers on "walks" through each park's most popular and accessible places, where he explains the identification and behavior of the birds that visitors are most likely to see. He closes each account with a review of the park's bird life and a list of key species. Pen-and-ink drawings illustrate many of the birds.

'One of history's most impressive field studies; an instant animal classic' TIME Jane Goodall's classic account of primate research provides an impressively detailed and absorbing account of the early years of her field study of, and adventures with, chimpanzees in Tanzania, Africa. It is a landmark for everyone to enjoy.

This work is about the first manatee ever conceived and born in captivity. The pregnancy was long (about 13 months), the mother was huge (over 900 pounds), and baby Lorelei was regarded by Zeiller and his coworkers at the Miami Seaquarium as a truly blessed event. Even one addition to the dwindling number of this endangered species was reason to rejoice. Zeiller's knowledge of the history and plight of this docile sea mammal is based on his work at the Seaquarium, where he helped develop the only extant breeding herd of manatees (including Lorelei's parents, Romeo and Juliet), the only gene pool of the animal in captivity at that time. With more than 100 photographs that help to document his personal experiences, Zeiller describes ""mercy"" missions with the Mermaid Rescue Squad to liberate animals caught in drainage ditches or to care for animals injured by boat propellers. He relates his efforts and adventures with Captain Jacques Cousteau to return ""Sewer Sam"" to the freedom of Crystal River. In uncomplicated language he presents scientific information on the habitat, distribution, physiology, and feeding and breeding habits of the manatee and its relatives. Manatees are nearing extinction not because of public insensitivity, he believes, but because of a lack of knowledge. His intention throughout the book is to increase public awareness of the crises. ""Destroying or saving 60,000,000 years of evolution is in our hands"", he writes. And, from the Epilogue: ""We have named Lorelei's son (Juliet's grandson) Hugh.

'This long-awaited update to the acclaimed first edition is the definitive guide to a complex and intriguing family. The species accounts and taxonomic treatments have been fully revised in line with recent studies, and the all-new plates and photos complete this remarkable work. Highly recommended.' - Dominic Mitchell Beautiful, colourful, often fearless hunters of large insects and small vertebrates, shrikes are among the most admired of all avian groups. The group is widespread (particularly in the Old World) with a large number of species, though many populations have plummeted in recent years, especially in Europe. This is a second edition of Norbert Lefranc's Shrikes, fully updated from its 1997 predecessor. The introductory texts have been significantly expanded and six new sections have been added in the species accounts: vagrancy, foraging behaviour, breeding success, population trends, conservation and taxonomic notes. Special attention has been given to the latest developments in shrike systematics, not forgotten by the DNA revolution. The species accounts give information about the past and current distribution, along with threats and conservation status. Detailed and fully revised maps accompany the authoritative text, along with hundreds of high-quality photos showcasing racial and ageing differences as well as interesting aspects of shrike behaviour. An exceptional new series of plates by Tim Worfolk have been created, with more individual plumages shown than in the previous edition. This beautiful book represents the definitive account of shrikes and their relationships, appearance, conservation and lifestyle; it will be treasured by birdwatchers and professional ornithologists alike.

The marsupials are an important order of mammals that have evolved along lines parallel to eutherians. This book brings together what is known about one very important sense needed for survival - hearing. It documents various studies of the hearing capacities of marsupials and relates this information to their vocal behavior. To what sounds do marsupials respond? What are the spectra of their vocalizations? The organization of the brain auditory pathways of marsupials is compared with those of eutherian mammals and related to the structure of the auditory periphery. The fact that much of the early development of marsupial young occurs outside the mother's body enables the possibility of discoveries about the early development of brain and hearing relevant to all mammals.

Health and welfare issues of brachycephalic (flat-faced) animals are one of the most pressing problems facing companion animals right now. Dogs, in particular, are suffering from a 'brachycephalic crisis' resulting from a perfect storm where predispositions to an array of health issues are amplified by a population boom for certain brachycephalic breeds such as the French Bulldog and Pug. But yet, for many owners, these dogs represent the perfect companion: endearing personas and cute looks in a socially desirable package. So where is the truth in all of this? This book will equip veterinary professionals, animal welfare scientists, breeders and owners with the fuller story about brachycephalic health and welfare. The first half of the book provides the context of how and why we are in this crisis, offering in-depth historical, social, ethical, communication, nursing, welfare, epidemiological, genetics and international perspectives. The second half shifts towards the clinical arena, with chapters that cover the background, diagnosis, treatment and prevention of the many unique healthcare needs of brachycephalic animals. Cutting-edge knowledge is shared on a range of disciplines including respiratory disease, ophthalmology, dermatology, dentistry, neurology, obesity, reproduction and anesthesia. With twenty chapters written by world-leading experts, lifetimes of experience and knowledge are condensed into the first book dedicated exclusively to brachycephaly in companion animals. This essential reference resource will inform, challenge and stimulate; it will open your mind to new opportunities for you to improve the welfare of brachycephalic animals by your personal and collective choices and actions. But prepare to be surprised: you may just find that your views on brachycephaly in companion animals will be changed forever.

In this dazzling literary collection, writers explore and celebrate their lives with and love for birds-detailing experiences from Alaska to Bermuda, South Dakota to Panama. In When Birds Are Near, fresh new voices as well as seasoned authors offer tales of adventure, perseverance, and fun, whether taking us on a journey down Highway 1 to see a rare California Condor, fighting the destruction of our grasslands, or simply watching the feeder from a kitchen window. But these essays are more than just field notes. The authors reflect on love, loss, and family, engaging a broad array of emotions, from wonder to amusement. As Rob Nixon writes, "Sometimes the best bird experiences are defined less by a rare sighting than by a quality of presence, some sense of overall occasion that sets in motion memories of a particular landscape, a particular light, a particular choral effect, a particular hiking partner." Or, as the poet Elizabeth Bradfield remarks, "We resonate with certain animals, I believe, because they are a physical embodiment of an answer we are seeking. A sense of ourselves in the world that is nearly inexpressible." When Birds Are Near gives us the chance to walk alongside these avid appreciators of birds and reflect on our own interactions with our winged companions.

This book reviews what is known about the behaviour and population ecology of a popular shorebird, from a scientific conservation perspective. The plight of this bird highlights the many conflicts of interest in coastal zones, between human activities such as shellfishing, land reclamation, barrage construction, and industrial pollution, and the needs of wildlife for food and suitable habitats. As well as detailing Oystercatcher natural history - including the well-known specialization in feeding technique shown by individuals - the authors use their field studies of individual variations in behaviour to produce population models. This novel approach provides tools for predicting how populations will respond to the many environmental changes to which the coastal zone is subject. It thus can play a role in coastal management schemes that seek to balance the needs of people and wildlife, and suggests that the same methods can be applied in other situtations. The volume contains fifteen well-integrated chapters by an international team of contributors, and is fully referenced.

The definitive photographic guide to the amazing avifauna of Borneo. The world's third largest island, divided between three countries - Indonesia, Malaysia and Brunei - Borneo is home to some of the oldest rainforests in the world, estimated to be 140 millions years old, and an avifauna of around 600 recorded bird species. It is a haven for birdwatchers and a frontrunning biodiversity hotspot. A range of habitats contributes to a diverse and exciting birdlife, which features colourful forest dwellers, mighty canopy dwelling hornbills, soaring raptors, as well as a host of charismatic endemics species and subspecies confined to this unique and special island. This guide is the perfect companion for any wildlife-savvy visitor to the island. It includes superb photography of more than 300 commonly encountered species, including all endemics and many subspecies. Concise text, covering key information on identification, habitat and distribution, and the best birdwatching sites, accompanies the photos to guide identification.

Following the success of earlier ‘Quick Guide’ books, this slim little volume tackles one of the few groups of mammals that can fly. Divided into large fruit bats and smaller insecteating bats, this ultimate quick identification guide covers Africa’s 12 bat families. An informative introduction touches on evolution, flight, echolocation and reproduction, demystifying an animal that is all too often misunderstood. The text describes the facial characteristics and wing shapes common to each family and points out features that can help to distinguish between them. But it is the photographs and annotated line drawings that are most useful for identification. They include bats in flight and roosting sites, and close-ups of facial structures and wings that highlight key diagnostic attributes. An added extra is a photographic section showing the skulls of a variety bats.

This is a valuable guide for anyone with an interest in wildlife and its less common members.

A charismatic and arresting bird, the Painted Stork inhabits the plains and wetlands of India and Southeast Asia. This near-threatened species provides a good model through which to explore a variety of ecology and conservation issues. As a colonial nester, it is also useful for considering questions related to evolution and the development of avian coloniality. The Painted Stork sometimes nests opportunistically in the middle of large cities – the Delhi Zoo colony, for instance, has been active since 1960. This offers a splendid opportunity to study the species at close range, as attested by this book's lively photographic component. The Painted Stork is an important indicator of its wetland habitats, which themselves are highly threatened. Since environmental toxins, particularly organochlorine pesticides, travel rapidly along aquatic food chains, the study of piscivorous birds like the Painted Stork assumes special significance. Equally vulnerable today are the nesting colonies, located in marshes, village reservoirs and the wider countryside, including in urban settings. Perhaps because their natural nesting areas are becoming scarce due to habitat loss, colonial waterbirds look for suitable sites in parks and gardens. Hence, the behaviour of this species reflects changes occurring in its environment. Birds also help us monitor the effects of global climate change, and one of the most significant dimensions of the Painted Stork is its dependence upon the monsoon. How exactly do these seasonal rains govern the food cycles in wetlands? And what happens when the monsoon fails? Covering all aspects of Painted Stork ecology, behaviour, conservation and its relationship with humans, this accessible monograph contains a wealth of new insights.

Although feeding has not yet been thoroughly studied in many vertebrate taxa, and different conceptual and methodological approaches make a synthesis difficult, the aim of this volume is to provide a comprehensive overview of the feeding design in aquatic and terrestrial vertebrates with a detailed description of its functional properties. The book focuses on the constant interaction between function and form, behaviour and morphology in the course of evolution of the feeding apparatus and feeding mechanism in both a complementary and basic manner in relation to survival, interspecific competition, adaptation to environmental changes and adaptive radiation. Special emphasis is given to the quantification of the observational and experimental data on the morphology and biomechanics of the feeding design and its elements - jaws, teeth, hyoidean apparatus and tongue in order to allow the present and further comparisons in an evolutionary perspective.

Originally published in 1976, the object of this volume was to present a relatively up-to-date overview of what was known, what was suspected, and what remained to be discovered concerning the general question of the evolution of the vertebrate brain and behaviour, and to present a list of references for those who wanted to delve deeper into one or another aspect of the problem. Accordingly, it contains chapters by palaeontologists, sensory morphologists and physiologists, comparative neurologists and comparative psychologists. The chapters are arranged in a sequence loosely approximating the order in which the various animals, brain structures, or behaviour first appeared. Therefore, the chapters fall naturally into sections, each section directed to a group of vertebrates, beginning with those which have very remote common ancestry and progressing to those with more recent common ancestry with mankind.

Topics covered in this volume include: transformation morphology on structures in the head of cichlid fishes; the structure and function of fish liver; atretic follicles and corpora lutea in the ovaries of fishes; effects of gill dimension on respiration; and the efects of pesticides on fish.

For the first time in ichthyological literature, the author has analyzed the structure of fish populations in inland reservoirs based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes, and seven from large reservoirs in plains. Special attention has been paid to the main indicator of the structure of population - correlation between the age of ichthyomass culmination and mass maturation. Data have been presented on age-related changes of ichthyomass in many generations of 11 species of commercially important fish. It is shown that populations of the investigated species of fish attain their maximum ichthyomass before reaching mass maturation or both these events are concurrent. Three types of population structure have been identified and their characteristics presented. The material presented in the book and conclusions derived are of great interest both for developments in population ecology of fish and the theory of optimal fishing. The book is intended for ichthyologists, hydrobiologists, and ecologists studying theoretical bases of fish ecology and tackling applied questions of regulated fishing and conservation of fish stocks.
