This title is suitable for beginners of all ages as well as younger birders – in fact, for anyone daunted by the prospect of getting started in the captivating pastime of birding.

The social calls of bats are an area about which relatively little is known, with more research still required to expand our understanding. However, these calls are increasingly recognised as a useful aid to identification: they appear to be species specific and are indicative of behaviour – as in territorial activity of males during the mating season. Because the gathering and interpretation of bat echolocation data are a matter of course during research, conservation and consultancy, it is a logical progression to build momentum behind the consideration of social calls in mainstream bat-related work. A better understanding of this subject could mean that non-intrusive survey methods are developed, ensuring that what is being observed is, as far as possible, purely natural behaviour. In turn this will contribute to better interpretation and more suitable mitigation, compensation and/or enhancement solutions. The book summarises what is understood so far about social calls of the bat species occurring in Britain and Ireland, and north-west Europe. This new edition has been updated and expanded throughout, now containing: foreword by the bat authority Michel Barataud, author of Acoustic Ecology of European Bats   almost double the number of figures and tables as appeared in the first edition completely overhauled call library, all in full spectrum format, with new additional examples  three entirely new chapters, covering bat-related acoustics, settings for social interaction, and survey guidelines The material will be useful to people carrying out bat studies, at whatever level and for whatever purpose, and will also encourage others to undertake further research. What's more, social calls are fascinating to listen to: they are, after all, produced with listeners in mind (other bats). In light of this, the book is accompanied by an extensive downloadable library of sound files which offer a unique gateway into the private life of bats. 

Somite development is a unique and important topic; unique because somitic mesoderm is the first tissue to become segmented, important because the somites - once established - exert a profound influence on other seg mental structures which form later. Somite development is of interest at a number of levels. In one aspect, demarcation of a specific number of somites and size regulation, it is a particularly intriguing example of embryonic pattern formation, 'especially in vew of its possible relation to homoeobox-controlled segmentation in insects. At another level, somite development has long been studied by compara tive anatomists, but only recently has new light been thrown on such sub jects as segmentation of the head, proposed in the 18th century by Goethe and now a live issue for developmental biologists. Somit es are simple when they first appear, but very complex structures arise from them. These include the vertebrae and the axial and other muscles and consequently there is a wealth of morphogenetic problems to be explored. Sometimes their morphogenesis is disturbed, by genetic or environ mental factors, and there are many clinical conditions which arise as a result."

A comprehensive work intended for anyone maintaining captive bats, Bats in Captivity is the only multi-volume series of its kind, detailing the captive care of bats worldwide. This volume comprises 25 papers by 37 contributing authors. It contains information on the legal aspects of maintaining and shipping bats, plus papers on developing traveling trunks and loan boxes, the use of ultrasonic mobility devices in education programs, conditioning and training bats for public demonstration, their use in outreach programs, and exhibiting bats in zoological institutions. In addition, there is comprehensive information on excluding bats from man-made structures, as well as how bat houses and artificial roosts are constructed and used.

Bringing together recent advances in the research into the ecology and biology of brown and sea trouth, this book places them in their ecological setting and shows how an understanding of their biology and environment aids efficient management of both fish stocks and the surroundings. In particular, it concentrates on the management of the fish in natural flowing waters, and discusses issues such as how to determine an efficient feeding strategy and the influence of hatchery stocks upon wild populations. A detailed case study focusing on the French experience is of especial interest. Biology and Ecology of the Brown Sea Trout synthesizes the considerable body of research available and provides a significant tool for the better management and conservation of these important fish.

Continues to be clear, concise and very easy to understand Remains an important resource for uncommon conditions The differential diagnosis segment is a big selling point Content is now thoroughly up to date, including for instance - significant scientific advances in diagnostic procedures, new classification of microbes. The color images are exceptional quality and now presented in a larger format. This second edition includes five additonal section on pythiosis, equine encephalosis, Acinetobacter baumanii, enteric coronavirus-induced disease, and viral hepatitis. These emerging diseases in equine medicine are duly elaborated upon in this second edition. The most dynamic changes in veterinary medicine concern the development of new molecular diagnostic techniques and therapies, and these have been updated with most recent references throughout this second edition. The practicality of the book for clinicians remains warranted by means of the included appendices containing a list of differential diagnoses based on clinical signs to support clinical decision-making, and a list of zoonoses and reportable diseases, and an elaborate illustrated appendix on clinical pathology and hematology. Equally dynamic is the field of emerging infectious diseases especially in the human-animal interface. The new edition emphasises the important role of the clinical and research veterinarian at forefront in recognizing and diagnosing new emerging infectious diseases.

This book presents perspectives on the past and present state of the understanding of snake origins. It reviews and critiques data and ideas from paleontology and neontology (herpetology), as well as ideas from morphological and molecular phylogenetics. The author reviews the anatomy and morphology of extant snakes. Methods are also critiqued, including those empirical and theoretical methods employed to hypothesize ancestral ecologies for snakes. The modern debate on squamate phylogeny and snake ingroup phylogeny using molecules and morphology is examined critically to provide insights on origins and evolution. Key Features Important major evolutionary transformation in vertebrate evolution Continuing historical debate in vertebrate paleontology Of wide interest to a core audience of paleontologists, herpetologists, and morphologists Author acknowledged as prominent contributor to debate over snake origins Based on remarkable well preserved fossil specimens

The first book on zoo/captive animal behavior and how this applies to welfare. Despite growing evidence of the need to implement more suitable, naturalistic practices into zoo animal welfare, it still seems to be somewhat overlooked - this book will address this oversight. Includes specific detail and examples focusing on taxa, a huge factor in managing animals in zoos that has not previously been addressed in this way. Covers invertebrates as well as vertebrate species. Would be a recommended or core text on Zoo Biology courses, BScs in Animal Science, and Animal Welfare MScs, as well as an invaluable practitioner reference. A lot of students interested in animal behaviour are interested in zoos. Each chapter covers species-specific content include the following information: Ecology and natural history as relevant to the zoo, behaviour and welfare measures based on ecological knowledge, feeding ecology and nutritional management, mating systems and reproductive characteristics, enrichment and behavioural diversity. The chapters are consistently formatted for ease of information, with end of chapter summaries, boxes with selected enrichment devices or welfare assessment methods for assessing welfare state, and directed reading of peer reviewed and other reputable sources that help advance care. A final Part explores welfare assessment tools, quality of life, veterinary interventions and evidence-based approaches. It looks at ways to increase the value of zoo and aquarium animals by enhancing visitor interest and visitor behaviour change. Also, research needs for keepers and how to build evidence into a daily routine, as well as management of native species programmes and the future of zoo research.

This comprehensive introductory text integrates evolutionary, ecological, and demographic perspectives with new results from field studies and contemporary noninvasive molecular and hormonal techniques to understand how different primates behave and the significance of these insights for primate conservation. Each chapter is organized around the major research themes in the field, with Strier emphasizing the interplay between theory, observations, and conservation issues. Examples are drawn from the "classic" primate field studies as well as more recent studies, including many previously neglected species, to illustrate the vast behavioral variation that exists across the primate order. Primate Behavioral Ecology 6th Edition integrates the impacts of anthropogenic activities on primate populations, including zoonotic disease and climate change, and considers the importance of behavioral flexibility for primate conservation. This fully updated new edition brings exciting new methods, theoretical perspectives, and discoveries together to provide an incomparable overview of the field of primate behavioral ecology and its applications to primate conservation. It is considered to be a "must read" for all students interested in primates.

This book addresses the differentiation control of skeletal muscle in different locations of the vertebrate body Particular attention is paid to novel regulatory molecules and signals as well as the heterogeneity of origin that have revealed a developmental overlap between skeletal and cardiac muscle. Different functional muscle groups are the product of the evolution of the vertebrate classes, making a phylogenetic comparison worthwhile for understanding the role of muscle stem cells and precursors in myogenesis. New insights into the hierarchy of transcription factors, particularly in the context of these different muscle groups have been gained from detailed investigations of the spatio-temporal and regulatory relationships derived from mouse and zebrafish genetics and avian microsurgery. Importantly, epigenetic mechanisms that have surfaced recently, in particular the role of MyomiRs, are also surveyed. With an eye to the human patient, encouraging results have been generated that identify parallels between embryonic myogenesis and regenerating myofibers due to common regulatory molecules. On the other hand, both processes differ considerably in quality and complexity of the processes employed. Interestingly, the heterogeneity in embryonic sources from which skeletal muscle groups in the vertebrate including the human body take origin is paralleled by differences in their susceptibility to particular muscle dystrophies as well as by the characteristics of the satellite cells involved in regeneration. The progress that has been made in the field of muscle stem cell biology, with special focus on the satellite cells, is outlined in this book by experts in the field. The authors review recent insights of the heterogeneous nature of these satellite cells regarding their gene signatures and regeneration potential. Furthermore, an improved understanding of muscle stem cells seems only possible when we study the impact of the cell environment on efficient stem cell replacement therapies for muscular dystrophies, putting embryological findings from different vertebrate classes and stem cell approaches into context.

This book is the first veterinary textbook dedicated to nursing care plans. It offers a broad overview of the theory and practice of care planning in veterinary nursing, answering three key questions: What are nursing care plans? Why should nursing care plans be used in practice? How should nursing care plans be used in practice? Author Helen Ballantyne provides basic definitions and explanations which will be useful to those unfamiliar with nursing care plans. For those veterinary nurses and technicians who are using nursing care plans, the content stimulates debate and discussion, by covering some of the philosophical and theoretical aspects of nursing and drawing comparisons and contrasts between the veterinary and human nursing roles and contexts. There is a pressing need for veterinary nurses to establish themselves as professionals and develop their unique role within the veterinary care team. Nursing care plans are a core tool to support that development. It is hoped that veterinary nurses may borrow tools from the pages of this book or use it as a resource design their unique care plans: either way, this practical guide will support the application of care planning, no matter the species of the animal kingdom for whom you are caring.

Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements.

The population of the Persian leopard (Panthera pardus saxicolor) has drastically declined; this Asian leopard subspecies has disappeared from some parts of its former range. Containing large areas of potential habitats with leopard presence across almost all of its provinces, Iran is known to be the last stronghold for the Persian leopard in the region. This book comprehensively covers research, management and conservation practices of the Persian leopard, including: * The first phase of the Persian Leopard National Action Plan in Iran together with an innovative leopard insurance program and a contingent valuation practice with respect to the wildlife trafficking law enforcement in Iran * Research on a hypothesis about the risk of a major fragmentation and splitting the leopard distribution range in Iran into a northern and a southern parts * An innovative and empirically fitted species- and region-specific approach for assessing the cumulative effect of land use and land cover changes on the leopard persistence * Distribution modeling of leopard potential habitats on a regional basis, accompanied by ground validation techniques * An evaluation to three threshold rules to define the habitat suitability indices * Persian leopard habitats and relative corridors in the trans-boundary areas of the East Azarbaijan province of the northwest of Iran in the Caucasus Ecoregion. The innovative research and conservation approaches presented in this book will be of great interest to those studying the leopard and other large carnivore species. The innovative models presented in this book about cumulative effect of the land use and land cover changes will be beneficial to land use managers, planners and decision makers in selecting wildlife friendly solutions for development programs. The strategic and action planning model as well as the leopard compensation program as an insurance scheme are developed specifically for the local condition and leopard status in Iran.

Elephants are a keystone species and have been a part of the magic of the thickly forested land of South Africa for millennia. This book focuses on the history and work of Knysna Elephant Park, a leading South African elephant research facility that has been home to more than 40 elephants in 25 years. Unfortunately, all the mystique of the Knysna elephant has been reduced to a single elephant left alive. Exploring a wide range of topics, this book covers the impact of elephants' interactions with tourists, how they recover from trauma and even their relevance in human healthcare. Renowned elephant researchers explain the majesty of the elephant brain, which has the largest temporal lobe devoted to communication, language, spatial memory and cognition. To this effect, the book emphasizes the threat of poaching to these gentle giants, which has almost forced them to extinction. Perhaps if humans pay attention to how elephants symbolize our relationship with nature, we can learn important lessons about humanity itself.

This book provides an introduction to the latest gene mapping techniques and their applications in biomedical research and evolutionary biology. It especially highlights the advances made in large-scale genomic sequencing. Results of studies that illustrate how the new approaches have improved our understanding of the genetic basis of complex phenotypes including multifactorial diseases (e.g., cardiovascular disease, type 2 diabetes, and obesity), anatomic characteristics (e.g., the craniofacial complex), and neurological and behavioral phenotypes (e.g., human brain structure and nonhuman primate behavior) are presented. Topics covered include linkage and association methods, gene expression, copy number variation, next-generation sequencing, comparative genomics, population structure, and a discussion of the Human Genome Project. Further included are discussions of the use of statistical genetic and genetic epidemiologic techniques to decipher the genetic architecture of normal and disease-related complex phenotypes using data from both humans and non-human primates.

This book will take readers on a flying visit round the world, scouring the seven continents for the biggest, brightest and best birds on the planet. Urban Jungle creator Vicky Woodgate perfectly captures the brilliance of the bird world, each chapter taking us to a new continent and introducing birds from hummingbirds to hawks, and parrots to penguins.
