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.
Given their roles in the ecosystem, raptors are widely considered the flagship or umbrella species among birds. Most species undertake a seasonal journey that is impressive because of the length, and the imposing natural barriers such as deserts and seas that they fly over. The migration of birds of prey has unique characteristics in the animal world because of their morphology and flight style. The flying path of Afro-Palearctic migrants between breeding and wintering grounds is determined by several factors such as morphology of the birds, geography, behavioural adaptations. The book analyses the migration patterns of raptors along the Afro-Palearctic migratory system, and summarizes the recent research on these top predator species. Behavioural adaptations such as the importance of social interactions and the modulation of the different flight styles as well as ecological interactions with the encountered environment and weather conditions en route are described in the book. Moreover, the impact of climate change on the migratory behaviour and key conservation issues are discussed. The book provides an overview of the migratory characteristics and flyway patterns of all European raptors species and also some Asian ones. These chapters have been written by some of the most important raptor specialists, giving a complete picture of the different migration strategies on the basis of both traditional methods and new technologies.

Changes in farmland management throughout the twentieth century, including agricultural intensification and increasing mechanisation, have resulted in the loss of habitat for many species. The Corncrake is one such species that has faced multiple challenges to its survival. Although it was once a common bird throughout northern Europe, the breeding areas of Corncrakes have been steadily reduced to a fraction of what they once were, and in many areas their continuation as a regularly breeding bird is in serious doubt. In addition, the behaviour of the Corncrake, nesting under the cover of tall grass and undertaking annual long-distance migrations, means that for most of the last hundred years, its detailed ecology has remained mysterious and little understood. Although there have been millions of words written about the Corncrake in scientific papers, until now there has been no full-length book that attempts to capture all the aspects of its ecology, and to present this information to non-specialists. As a result, until very recently, many important facts about its lifestyle and behaviour have not been widely known, even among ornithologists. Although scarcely seen in its natural habitat, the Corncrake is well-known in many rural areas due to its characteristic (and persistent) night-time calling, but new discoveries with the aid of acoustic science have proved surprising, and may offer new ways of improving the location, identification, and management options to protect and enable the population of this iconic species to recover, even to thrive in our countryside. A new appreciation of the requirements of this species and the ways in which our sensitive management of the whole landscape, both in its potential breeding areas across Europe and Asia and in the seasonal quarters in regions of Africa, offer new hope for the future of this fascinating bird.
This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat songs, dialects and calls. Part III discusses the influence of the environment on bat behavior, particularly with regard to roosting and foraging. This book addresses the needs of researchers working in behavioral sciences, evolution and ecology.

This compact, easy-to-use guide features: - 152 of the region's mammal species - key identification features showing how to differentiate between similar species - distribution maps and a list of major parks and reserves indicating where species are likely to be seen - quick reference key on inside cover - thumbnail silhouettes of each family group for quick identification This new revised edition is an ideal pocket-sized travelling companion for nature lovers and visitors to nature reserves and wildlife areas.
This book explores the life of Henry Dresser (1838-1915), one of the most productive British ornithologists of the mid-late nineteenth and early twentieth centuries, and is largely based on previously unpublished archival material. Dresser travelled widely and spent time in Texas during the American Civil War. He built enormous collections of skins and eggs of birds from Europe, North America and Asia, which formed the basis of over 100 publications, including some of the finest bird books of the late nineteenth century. Dresser was a leading figure in scientific society and in the early bird conservation movement; his correspondence and diaries reveal the inner workings, motivations, personal relationships and rivalries that existed among the leading ornithologists. -- .
Snow Leopards: Biodiversity of the World: Conservation from Genes to Landscapes is the only comprehensive work on the biology, behavior, and conservation status of the snow leopard, a species that has long been one of the least studied, and hence poorly understood, of the large cats. Breakthroughs in technologies and methodologies to study this elusive cat have come rapidly, including non-invasive genetics, camera traps, and GPS-satellite collaring. The book begins with chapters on the genetic standing and taxonomy of the snow leopard, followed by chapters on their behavior and ecology. Additional contributions follow on the current and emerging threats to the species, which include longstanding concerns, such as poaching and conflicts with livestock, and new and emerging threats such as mining and climate change. A section on conservation solutions, backed by valuable case studies, starts with an overview of the important role mountain communities play in assuring the snow leopard's long-term persistence. In addition, chapters on the role of captive snow leopards for the conservation of the species, state-of-the-art techniques and technologies for studying and monitoring snow leopards, status reports from around the region, and future perspectives, such as transboundary conservation initiatives, international conventions (CITES, CMS, etc.), the role of the IUCN Cat Specialist Group and the Snow Leopard Network, and undertakings such as the Global Snow Leopard Forum facilitated by the World Bank are also included.
New in Struik Nature’s Pocket Guide series, this book covers an astonishing 500 southern African birds yet is small enough to fit in your pocket. It is loaded with information that makes for quick and easy bird identification:
This book offers a new explanation for the development of flight in mammals and offers detailed morphological descriptions of mammals with flapping flight. The skeletomuscular apparatus of the shoulder girdle and forelimbs of tree shrews, flying lemurs and bats is described in detail. Special attention is paid to the recognition of peculiar features of the skeleton and joints. For the basic locomotor patterns of flying lemurs and bats, the kinematic models of the shoulder girdle elements are developed. The most important locomotor postures of these animals are analyzed by means of statics. The key structural characters of the shoulder girdle and forelimbs of flying lemurs and bats, the formation of which provided transition of mammals from terrestrial locomotion to gliding and then, to flapping flight, are recognized. The concept is proposed that preadaptations preceding the acquisition of flapping flight could have come from widely sprawled forelimb posture while gliding from tree to tree and running up the thick trunks. It is shown that flying lemur is an adequate morphofunctional model for an ancestral stage of bats. The evolutionary ecomorphological scenario describing probable transformational stages of typical parasagittal limbs of chiropteran ancestors into wings is developed.
In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs. The subject index, species index and the abundant illustrations add extra value to this long awaited book. Developmental Biology of Teleost Fishes will be a valuable tool for scientists and students in the fields of biology, developmental biology, molecular biology and fish biology.
A comprehensive photographic guide to the world's gull species With more than 50 gull species in the world, this family of seabirds poses some of the greatest field identification challenges of any bird group: age-related plumage changes, extensive variations within species, frequent hybridization, and complex distribution. Gulls of the World takes on these challenges and is the first book to provide a comprehensive look at these birds. Concise text emphasizes field identification, with in-depth discussion of variations as well as coverage of habitat, status, and distribution. Abundant photographs highlight identification criteria and, crucially, factor in age and subspecific field separation. Informative species accounts are accompanied by detailed color range maps.

Every species is illustrated with magnificent colour paintings and a stunning collection of photographs, chosen to illustrate the key field marks which can be used to separate each species in the field. The author's unique depth of experience and knowledge, coupled with the artist's unrivalled skill, have come together to produce a neat, practical field guide that will enable any observer to quickly identify any mammals they may encounter at sea.
Building on the success of its popular predecessor, the second edition of Ecotoxicology of Amphibians and Reptiles presents newly available findings on the species that are important environmental indicators. This new edition covers nearly twice as many topics as the first, including recent developments in the ecotoxicology of amphibians and reptiles, the current status of these animals, and intrinsic factors that affect their susceptibility to contaminants. The book also provides the latest information on specific groups of contaminants and their effects and body burdens in herpetafauna. After a review of how contaminants interact with other ecological factors, the text explores concerns for the future. New in the second edition: New research on the effects of pesticides, heavy metals, endocrine disrupting chemicals, and UVB Increased focus on the effects of contaminants rather than merely reporting residue information A synthesis of information on atrazine and its effects on gonads at low concentrations Coverage of the potentially alarming new cadre of chemicals that have recently or are about to come on the market for which there is very little or no information Important advances in surveying and monitoring One of the major factors behind the writing of the first edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. With chapter contributors carefully selected by the team of editors as leaders in their fields, this book provides an authoritative compendium of the most recent information on effects and residues coupled with a syntheses of what these numbers mean to science and policy.
Lemurs: Ecology and Adaptation brings together information from recent research, and provides new insight into the study of lemur origins, and the ecology and adaptation of both extant and recently extinct lemurs. In addition, it addresses issues of primate behavioral ecology and how environment can play a major role in explaining species variation. Moreover, in a larger context, the information contained in this volume expands our knowledge of primate ecology and allows us further insight into mammalian adaptations to unusual and often harsh environmental conditions that arise from both natural and anthropogenic factors. The book is divided into two sections. The first section is a background to lemurs and their ecology and it includes chapters on origins of lemurs, history of ecological studies on lemurs in Madagascar, theories relating to the evolution of lemur traits, and ecology of the recently extinct (sub-fossil) lemurs. Section two is comprised of chapters focusing on the ecology and adaptations of many species of extant lemurs to the diverse habitats found on Madagascar, and in some cases, adaptations to extreme climatic variability and natural disasters.
The twelve papers consider: the origins of the study of mammalogy in North America; aspects of economic importance of mammals; ecology of mammals; anatomy and physiology of the anterior pituitary and endocrine hypothalamus and their interactions; evolution of mammalian behavior; evolution of mammals
Raptors of the World (Helm, 2001) is the definitive handbook to this most popular group of birds. This new field guide uses all of the plates from Raptors of the World, with a concise, revised text on facing pages, to create a conveniently-sized, lightweight field reference covering all 340 raptor species. Several of the plates have been reworked and repainted for this guide. The book also has an updated colour distribution map for each species. Much of the extensive introductory material has been retained in this guide, with the addition of a complete species list containing all subspecies and brief details of their ranges. Armed with this guide, birders will be able to identify with confidence any raptor encountered anywhere in the world.
This book reviews up-to-date knowledge on the biology of sole (Solea senegalensis and S. solea). These flatfish species are increasingly important in Europe both from the ecological and production point of view. This book is divided into two sections: A. general fisheries, aquaculture and engineering overviews; B. physiological, developmental, rhythmic, welfare and genetic aspects which will be of immense interest for the aquaculture industry. Experts, from both academia and research institutes, provide their expertise on sole biology.
Mullets (grey mullets) are a family (Mugilidae) and order of ray-finned fish found in temperate and tropical waters worldwide. There are approximately 80 species of mullet; these fish have been considered an important food source in Mediterranean Europe since Roman times. This book provides a long overdue update on the biology and ecology of mullets and features comprehensive coverage of the key features of the Mugilidae family, such as recent DNA evidence and morphological data that challenge the traditional taxonomy.
Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently decreasing in number since the Dust Bowl of the 1930s dramatically affected their core range. In May of 2014, the United States Fish and Wildlife Service listed Lesser Prairie-Chickens as a threatened species, granting them federal protection under the Endangered Species Act, which included a special rule recognizing significant conservation planning efforts made by state and federal wildlife agencies within the geographical range of the species. Although the listing was vacated by judicial ruling in September 2015, concern for persistence of the species persists. These actions illustrate the uncertain legal status and future conservation challenges for Lesser Prairie-Chickens. Ecology and Conservation of Lesser Prairie-Chickens provides a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists. It thoroughly reviews the life history, genetics, and ecology of the species, and is ultimately directed toward developing and establishing appropriate conservation management strategies. It presents a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It also addresses the challenges that natural resource managers continue to face in their current conservation efforts. While dealing with immediate and short-term issues in Lesser Prairie-Chicken conservation, this book is also a useful starting point for guiding future research, management, and conservation of the species. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series provides a definitive reference for researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.
Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the most vulnerable life cycle stages. The beauty, intriguing biology, and importance of these charismatic fishes at the interface of marine and terrestrial ecosystems have inspired numerous scientific studies. Adaptations of behavior, physiology, development, and ecology are gathered together for the first time in this book. Beach-Spawning Fishes: Reproduction in an Endangered Ecosystem is a comprehensive guide to beach spawning, a charismatic animal behavior that is seen in a surprising number of teleost species. This unexpected form of reproduction provides a window into the ecology of coastal areas, the behaviors and physiology necessary for fishes and their eggs to adapt to terrestrial conditions, and the threats and challenges for conservation and management. Beach-spawning species include important forage fishes such as the capelin, exotic fishes such as the fugu puffer, and the spectacular midnight runs of the California grunion.

This special book-format issue of Birds New Zealands journal Notornis is devoted to the birds of the Auckland Islands Maukahuka/Motu Maha, the largest and biologically most diverse island group in the New Zealand subantarctic region. Its 19 chapters, written by leading ornithologists, cover a wide range of topics, including the history of ornithological discovery, biogeography, the impacts of introduced mammals and people, prehistoric bird communities based on bone assemblages, and population, ecological and genetic studies of several of the endemic or otherwise notable birds of the island group including Auckland Island snipe, white-headed petrel, and several albatross species.
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. |
