Biology of Stress in Fish: Fish Physiology provides a general understanding on the topic of stress biology, including most of the recent advances in the field. The book starts with a general discussion of stress, providing answers to issues such as its definition, the nature of the physiological stress response, and the factors that affect the stress response. It also considers the biotic and abiotic factors that cause variation in the stress response, how the stress response is generated and controlled, its effect on physiological and organismic function and performance, and applied assessment of stress, animal welfare, and stress as related to model species.

Fish are a unique group which harbour some 30,000 species of helminths that do not occur in other vertebrates. This book deals specifically with parasitic worms of fish. It covers every aspect of their biology including identification, life-cycles, hostparasite relationships and ecology. It discusses approaches to studying parasitic worm infections, preference of species for particular host species, preference for dwelling in certain organs and tissues, biogeography, seasonality of infections and how parasites have evolved in parallel with their hosts. The book concludes with discussions of fish worms causing diseases in nature and in fish-farms. This section also addresses the value of parasitic worms in extending knowledge of the environments in which fish and their parasites dwell, from the use of worms as indicators of pollution or for determining the location, migrations, and feeding behavior of fish stocks. With the growth in fish farming such parasites have considerable economic as well as scientific significance.; This volume provides an account of these helminths and reviews how studies on fish worms have increased current knowledge of worm biology in general.; The bibliography contains over 3500 references and an appendix summarizes important information on biochemistry and physiology of fish worms.

After drawing its first breath, every newborn mammal turns his or her complete attention to obtaining milk. This primal act was once thought to stem from a basic fact: milk provides the initial source of calories and nutrients for all mammalian young. But it turns out that milk is a much more complicated biochemical cocktail and provides benefits beyond nutrition. In this fascinating book, biologists Michael L. Power and Jay Schulkin reveal this liquid's evolutionary history and show how its ingredients have changed over many millions of years to become a potent elixir. Power and Schulkin walk readers through the early origins of the mammary gland and describe the incredible diversification of milk among the various mammalian lineages. After revealing the roots of lactation, the authors describe the substances that naturally occur in milk and discuss their biological functions. They reveal that mothers pass along numerous biochemical signals to their babies through milk. The authors explain how milk boosts an infant's immune system, affects an infant's metabolism and physiology, and helps inoculate and feed the baby's gut microbiome. Throughout the book, the authors weave in stories from studies of other species, explaining how comparative research sheds light on human lactation. The authors then turn their attention to the fascinating topic of cross-species milk consumption-something only practiced by certain humans who evolved an ability to retain lactase synthesis into adulthood. The first book to discuss milk from a comparative and evolutionary perspective, Power and Schulkin's masterpiece reveals the rich biological story of the common thread that connects all mammals.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy and morality by virtue of our genes? From a scientist and writer whom E. O. Wilson has called 'the world authority on primate social behavior' comes a lively look at the most provocative aspects of human nature - power, sex, violence, kindness, and morality - through our two closest cousins in the ape family. For nearly twenty years, Frans de Waal has worked with both the famously aggressive chimpanzee and the lesser-known egalitarian, erotic, matriarchal bonobo, two species whose DNA is nearly identical to that of humans. He brings these apes to life on every page, revealing their personalities, relationships and power struggles, creating an engrossing narrative that explores what their behaviour can teach us about ourselves and each other.

Chameleons are fascinating creatures: they almost always evoke in people a strong response, be it delight, wonder or fear.

It also contains a clear identification guide to all southern African species - some 25 have been identified to date - together with distribution maps and colourful photographs of their many features and guises. For interested students, gardeners, naturalists and even just the curious, Chameleons of Southern Africa is an essential guide to these intriguing lizards.

The first comprehensive coverage of a subject that has fascinated natural historians for centuries. Avian vagrancy is a phenomenon that has fascinated natural historians for centuries. From Victorian collectors willing to spend fortunes on a rare specimen, to today's high-octane bird-chasing 'twitchers', the enigma of vagrancy has become a source of obsession for countless birders worldwide. Vagrancy in Birds explores both pattern and process in avian vagrancy, drawing on recent research to answer a suite of fundamental questions concerning the occurrence of rare birds. For each avian family, the book provides an in-depth analysis of recent and historical vagrancy patterns, representing the first comprehensive assessment of vagrancy at a global scale. The accounts are accompanied by hundreds of previously unpublished images featuring many of the most exceptional vagrants on record. The book synthesises for the first time everything we know about the subject, making the case for vagrancy as a biological phenomenon with far-reaching implications for avian ecology and evolution.

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.

Can one undertake a round-the-world trip with conservation uppermost in the mind? This is exactly what Nils Bouillard sought to do in 2019, adapting a popular concept in birding known as the 'big year' and focusing instead on bats. This had never been done before and so became the ideal platform to spotlight countless conservation projects across the globe. In this engaging and inspiring account we follow Nils on his adventures – along the way discovering the extraordinary diversity of bat appearances and behaviour, and learning how we might help to protect these fascinating creatures.

Eel of the genus Anguilla is an extraordinary fish, which due to its particular life cycle has fascinated biologists and physiologists ever since the pioneering works of Homer H. Schmidt in the 1930s. The Eel has become an excellent model for various aspects of adaptive physiological research. Despite that, several books dealing with eel biology, aquaculture, fishing, etc., have been published, but there still is a need for a text dealing with eel physiology. This book fills a void in eel literature by presenting various aspects of eel physiology in one comprehensive volume. With its numerous figures and tables and an extensive up-to-date bibliography, it will be of interest not only to researchers and students but also to people engaged in applied research in fishery and aquaculture. Eel is a commercially important fish, but it must be protected from over-exploitation; as such, conservation measures are necessary. It is hoped that this book will stimulate and suggest new lines of research.

Primate and Human Evolution provides a synthesis of the evolution and adaptive significance of human anatomical, physiological and behavioral traits. Using paleontology and modern human variation and biology, it compares hominid traits to those of other catarrhine primates both living and extinct, presenting a new hominization model that does not depend solely on global climate change, but on predictable trends observed in catarrhines. Dealing with the origins of hominid tool use and tool manufacture, it compares tool behavior in other animals and incorporates information from the earliest archaeological record. Examining the use of non-human primates and other mammals in modeling the origins of early human social behavior, Susan Cachel argues that human intelligence does not arise from complex social interactions, but from attentiveness to the natural world. This book will be a rich source of inspiration for all those interested in the evolution of all primates, including ourselves.

The definitive resource for finding, identifying, and conserving Maryland's amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity-and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.

The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.

Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

Are you curious about the remains of an animal you have found? This compilation of the most likely found body parts of animals eaten by raptors will help you identify your discovery. Including over 100 species of bird and mammal prey of raptors such as sparrowhawks, peregrines and hen harriers, this photographic guide highlights the common feathers, fur and other body parts found at raptor nests, roosts, plucking posts and other opportunistic spots. Discovering what raptors eat is an important part of confirming their feeding ecology and how this might change over time, vary on a local level or in response to changing prey populations, as well as dispelling myths and assumptions about what certain raptor species eat. Diet studies are vital for the conservation of raptor species; the more we know about what they need for survival the more we can predict and plan long-term for the protection and survival of raptors that may be vulnerable and in decline. This is the first book to show in detail the actual parts of a bird, mammal or other animal that you are likely to find in a garden, woodland or beneath a raptor roost. As more people take an interest in raptors and watch species such as peregrines via webcams and through watch groups, there is greater opportunity for finding prey remains. This book provides the first and most important step in identifying a prey species.

Metamorphosis and the transition from larvae or embryos to juveniles in fishes are important in order to answer, for example, questions about: (1) life-history styles and their modifications in evolutionary perspective and within current environmental demands; (2) the development and application of fisheries recruitment models, (3) the use of ontogenetic scales for interspecific comparisons, (4) the identification of ontogenetic shifts in resource use, and (5) the discovery of evolutionary interrelationships of species or genera. This volume is dedicated to recent studies and reviews of existing knowledge on this insufficiently-addressed area of ichthyology. Most of the papers in this volume were presented in Bratislava, Slovakia, at the 1st International Workshop of the Fish Ontogeny Network of Europe (FONE) in September 1997, a meeting sponsored in part by the European Commission. This volume emphasizes an integrated approach to the study of fish ontogeny, which is a process during which one event is related to another and everything is related to everything else, encompassing physiology, morphology, behaviour and niche. Within this comprehensive perspective, the papers in this volume are grouped along four major themes: reflections on early ontogeny and metamorphosis, organism-environment relationships, ontogeny of predator-prey interactions, and behaviour and ontogeny. Among other issues, the papers consider topics such as whether one can identify when fish metamorphosis ends, whether the larva period begins with hatching or with the onset of exogenous feeding, whether fish ontogeny is `saltatory' or `gradual', and whether larvae are eliminated in some fishes with direct development. The keynote paper of this volume reviews the main topics within contemporary paradigms and the final paper concludes that the onset of the juvenile period can be identified in some species, but precision remains problematic, emphasizing the need for further research in this dynamic area of fish biology.
