Vision is the sense by which we and other animals obtain most of our information about the world around us. Darwin appreciated that at first sight it seems absurd that the human eye could have evolved by natural selection. But we now know far more about vision, the many times it has independently evolved in nature, and the astonishing variety of ways to see. The human eye, with a lens forming an image on a sensitive retina, represents just one. Scallops, shrimps, and lobsters all use mirrors in different ways. Jumping spiders scan with their front-facing eyes to check whether the object in front is an insect to eat, another spider to mate with, or a predator to avoid. Mantis shrimps can even measure the polarization of light. Animal eyes are amazing structures, often involving precision optics and impressive information processing, mainly using wet protein - not the substance an engineer would choose for such tasks. In Eyes to See, Michael Land, one of the leading world experts on vision, explores the varied ways in which sight has evolved and is used in the natural world, and describes some of the ingenious experiments researchers have used to uncover its secrets. He also discusses human vision, including his experiments on how our eye movements help us to do everyday tasks, as well as skilled ones such as sight-reading music or driving. He ends by considering the fascinating problem of how the constantly shifting images from our eyes are converted in the brain into the steady and integrated conscious view of the world we experience.

"Glimpses of Creatures in Their Physical Worlds" offers an eye-opening look into how the characteristics of the physical world drive the designs of animals and plants. These characteristics impose limits but also create remarkable and subtle opportunities for the functional biology of organisms. In particular, Steven Vogel examines the size and scale, and trade-offs among different physical processes. He pays attention to how the forms and activities of animals and plants reflect the materials available to nature, and he explores the unique constraints and possibilities provided by fluid flow, structural design, and environmental forces.

Each chapter of the book investigates a facet of the physical world, including the drag on small projectiles; the importance of diffusion and convection; the size-dependence of acceleration; the storage, conduction, and dissipation of heat; the relationship among pressure, flow, and choice in biological pumps; and how elongate structures tune their relative twistiness and bendiness. Vogel considers design-determining factors all too commonly ignored, and builds a bridge between the world described by physics books and the reality experienced by all creatures. "Glimpses of Creatures in Their Physical Worlds" contains a wealth of accessible information related to functional biology, and requires little more than a basic background in secondary-school science and mathematics.

Drawing examples from creatures of land, air, and water, the book demonstrates the many uses of biological diversity and how physical forces impact biological organisms.

Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and their evolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking at how they evolved and how recent changes to our diet are now affecting dental health. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Mammalian skull structure is notably diverse; however at a basic level the jaw mechanism is remarkably similar, if not essentially the same, in the majority of mammals. Using simple models that are compared with real animals at every step, this book examines the basic structural features of the mammalian jaw mechanism from a mechanical point of view. It explores how the mechanical constraints placed on the jaw have contributed to the evolution of an efficient basic structure, used by many mammals, which precludes mechanical difficulties and uses a minimum amount of bone tissue. Throughout the book the emphasis is on conceptual understanding, with explanations linked together to form a complete story that can be applied to both fossil and extant mammals. Summarising over forty years of research from one of the leading pioneers in 3D jaw mechanics, this is a must-have for anyone interested in mammalian jaw morphology.

Animals have evolved remarkable biomechanical and physiological systems that enable their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of animal movement through a broad comparative and integrative approach, including basic mathematics and physics, examination of new and enduring literature, consideration of classic and cutting-edge methods, and a strong emphasis on the core concepts that consistently ground the dizzying array of animal movements. Across scales and environments, this book integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion. This second edition has been thoroughly revised, incorporating new content on non-vertebrate animal locomotor systems, studies of animal locomotion that have inspired robotic designs, and a new chapter on the use of evolutionary approaches to locomotor mechanisms and performance.

How are sights and sounds and smells converted into electrical signals in a form that can be interpreted by the nervous system? Although this process, called sensory transduction, began to be understood only relatively recently, so much progress has been made that it is now possible to say at least in outline (but in most cases in remarkable detail) how transduction occurs for all of the major sense organs of the body. Since the first edition was published in 2003, many new experiments have radically changed some of our previously-held views.This new edition fulfils the book's original aims, both as an accessible textbook and a general introduction to the senses, by bringing the contents fully up to date with the new information acquired over the last 15 years. In so doing, it continues to provide a comprehensive survey of one of the greatest achievements of modern biology and neuroscience - the unravelling of the mechanism of sensation. Sensory Transduction is written for advanced undergraduates, graduate students, and researchers in neurophysiology and sensory neuroscience. It is also of relevance and use to a broader audience of neuro, evolutionary, integrative, and comparative biologists.

Over half a billion years ago life on earth took an incredible step in evolution, when animals learned to build skeletons. Using many different materials, from calcium carbonate and phosphate, and even silica, to make shell and bone, they started creating the support structures that are now critical to most living forms, providing rigidity and strength. Manifesting in a vast variety of forms, they provided the framework for sophisticated networks of life that fashioned the evolution of Earth's oceans, land, and atmosphere. Within a few tens of millions of years, all of the major types of skeleton had appeared. Skeletons enabled an unprecedented array of bodies to evolve, from the tiniest seed shrimp to the gigantic dinosaurs and blue whales. The earliest bacterial colonies constructed large rigid structures - stromatolites - built up by trapping layers of sediment, while the mega-skeleton that is the Great Barrier Reef is big enough to be visible from space. The skeletons of millions of coccolithophores that lived in the shallow seas of the Mesozoic built the white cliffs of Dover. These, and insects, put their scaffolding on the outside, as an exoskeleton, while vertebrates have endoskeletons. Plants use tubes of dead tissue for rigidity and transport of liquids - which in the case of tall trees need to be strong enough to extend 100 m or more from the ground. Others simply stitch together a coating from mineral grains on the seabed. In Skeletons, Jan Zalasiewicz and Mark Williams explore the incredible variety of the skeleton innovations that have enabled life to expand into a wide range of niches and lifestyles on the planet. Discussing the impact of climate change, which puts the formation of some kinds of skeleton at risk, they also consider future skeletons, including the possibility that we might increasingly incorporate metal and plastic elements into our own, as well as the possible materials for skeleton building on other planets.

Nests, Eggs, and Incubation brings together a global team of leading authorities to provide a comprehensive overview of the fascinating and diverse field of avian reproduction. Starting with a new assessment of the evolution of avian reproductive biology in light of recent research, the book goes on to cover four broad areas: the nest, the egg, incubation, and the study of avian reproduction. New research on nest structures, egg traits, and life history is incorporated, whilst contemporary methodologies such as self-contained temperature probes and citizen science are also discussed. Applied chapters describe how biological knowledge can be applied to challenges such as urbanisation and climate change. The book concludes by suggesting priorities for future research. This book builds upon the foundations laid down by Charles Deeming's 2002 work Avian Incubation (available for readers of this book to access online for free), much of which remains relevant today. Read in conjunction with this previous volume, it provides an up-to-date and thorough review of egg biology, nest function, and incubation behaviour, which will be an essential resource for students of avian biology, as well as both professional and amateur ornithologists working in the field of avian reproduction.

Organized by body system, the new edition of this highly illustrated textbook covers the normal histological appearance of tissues in a wide range of animals, both domestic and exotic species, with relevant clinical correlates emphasizing the need to appreciate the normal in order to recognize the abnormal. In this update by two experienced veterinary pathologists and histology lecturers, new species, such as other companion mammals, aquatic species and livestock, are introduced into each chapter along with a wealth of new high-quality images. A new chapter covers epitehlial tissue and new techniques used in histology and histopathology are discussed throughout, including ISH and digital image analysis. Pathogenesis explanation is introduced in the current (and many new) cases of histopathology. The breadth of coverage-farm animals, dogs, cats, horses, birds, reptiles, amphibians, and fish-and the integration of normal and abnormal tissue provide a reference of lasting value to veterinary students as well as veterinary practitioners and pathologists needing a quick refresher.

Spatial patterns of movement are fundamental to the ecology of animal populations, influencing their social organization, mating systems, demography, and the spatial distribution of prey and competitors. However, our ability to understand the causes and consequences of animal home range patterns has been limited by the descriptive nature of the statistical models used to analyze them. In "Mechanistic Home Range Analysis," Paul Moorcroft and Mark Lewis develop a radically new framework for studying animal home range patterns based on the analysis of correlated random work models for individual movement behavior. They use this framework to develop a series of mechanistic home range models for carnivore populations.

The authors' analysis illustrates how, in contrast to traditional statistical home range models that merely describe pattern, mechanistic home range models can be used to discover the underlying ecological determinants of home range patterns observed in populations, make accurate predictions about how spatial distributions of home ranges will change following environmental or demographic disturbance, and analyze the functional significance of the movement strategies of individuals that give rise to observed patterns of space use.

By providing researchers and graduate students of ecology and wildlife biology with a more illuminating way to analyze animal movement, "Mechanistic Home Range Analysis" will be an indispensable reference for years to come.

Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.

The Crustacea is one of the dominant invertebrate groups, displaying staggering diversity in form and function, and spanning the full spectrum of Earth's environments. Crustaceans are increasingly used as model organisms in all fields of biology, as few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. Physiological Regulation is the fourth volume in The Natural History of the Crustacea series, and the first book in over twenty-five years to provide an overview of the comparative physiology of crustaceans. An understanding of physiology is crucial to a comprehension of the biology of this fascinating invertebrate group. Written by a group of internationally recognized experts studying a wide range of crustacean taxa and topics, this volume synthesizes current research in a format that is accessible to a wide scientific audience.

From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis.

The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives.

The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.

Communication is an essential factor underpinning the interactions between species and the structure of their communities. Plant-animal interactions are particularly diverse due to the complex nature of their mutualistic and antagonistic relationships. However the evolution of communication and the underlying mechanisms responsible remain poorly understood.
Plant-Animal Communication is a timely summary of the latest research and ideas on the ecological and evolutionary foundations of communication between plants and animals, including discussions of fundamental concepts such as deception, reliability, and camouflage. It introduces how the sensory world of animals shapes the various modes of communication employed, laying out the basics of vision, scent, acoustic, and gustatory communication. Subsequent chapters discuss how plants communicate in these sensory modes to attract animals to facilitate seed dispersal, pollination, and carnivory, and how they communicate to defend themselves against herbivores. Potential avenues for productive theoretical and empirical research are clearly identified, and suggestions for novel empirical approaches to the study of communication in general are outlined.

The Flexible Phenotype attempts a true synthesis of physiology, behaviour, and ecology by developing an empirical argument that describes the intimate connections between phenotypes and their environments. It portrays an ecological angle to the rapidly growing extended synthesis in evolutionary biology that incorporates developmental processes, self-organization, and the multiple dimensions of inheritance. The book starts with a synthesis of the principles guiding current research in ecophysiology, functional morphology, and behavioural ecology. Each aspect is illustrated with the detailed results of empirical work on as wide a range of organisms as possible. The integrated story of the flexible phenotype is woven throughout the book on the basis of the authors' long-term research on migrant shorebirds and their invertebrate prey. These birds travel vast distances from one environment to another, and the changing nature of their bodies reflects the varied selection pressures experienced in the course of their globe-spanning migrations. In essence, the authors argue for the existence of direct, measurable, links between phenotype and ecology, mediated by developmental processes. Their book outlines a more encompassing approach to evolutionary ecology, based on first principles in physiology, behaviour, and ecology. It aspires to encourage a further integration of ecology and physiology, as well as fostering a collaborative research agenda between ecologists, physiologists, and developmental biologists.

Introducing Biological Energetics is a novel, interdisciplinary text that presents biological understanding in terms of general underlying principles, treating energy as the overarching theme and emphasizing the all-pervading influence of energy transformation in every process, both living and non-living. Key processes and concepts are explained in turn, culminating in a description of the overall functioning and regulation of a living cell. The book rounds off the story of life with a brief account of the endosymbiotic origins of eukaryotic cells, the development of multicellularity, and the emergence of modern plants and animals.
Multidisciplinary research in science is becoming commonplace. However, as traditional boundaries start to break down, researchers are increasingly aware of the deficiencies in their knowledge of related disciplines. Introducing Biological Energetics redresses the reciprocal imbalance in the knowledge levels of physical and biological scientists in particular. Its style of presentation and depth of treatment has been carefully designed to unite these two readerships.

Birds have colonized almost every terrestrial habitat on the planet - from the poles to the tropics, and from deserts to high mountain tops. Ecological and Environmental Physiology of Birds focuses on our current understanding of the unique physiological characteristics of birds that are of particular interest to ornithologists, but also have a wider biological relevance. An introductory chapter covers the basic avian body plan and their still-enigmatic evolutionary history. The focus then shifts to a consideration of the essential components of that most fundamental of avian attributes: the ability to fly. The emphasis here is on feather evolution and development, flight energetics and aerodynamics, migration, and as a counterpoint, the curious secondary evolution of flightlessness that has occurred in several lineages. This sets the stage for subsequent chapters, which present specific physiological topics within a strongly ecological and environmental framework. These include gas exchange, thermal and osmotic balance, 'classical' life history parameters (male and female reproductive costs, parental care and investment in offspring, and fecundity versus longevity tradeoffs), feeding and digestive physiology, adaptations to challenging environments (high altitude, deserts, marine habitats, cold), and neural specializations (notably those important in foraging, long-distance navigation, and song production). Throughout the book classical studies are integrated with the latest research findings. Numerous important and intriguing questions await further work, and the book concludes with a discussion of methods (emphasizing cutting-edge technology), approaches, and future research directions.

Veterinary students and practicing technicians will find this book to be an important bench manual as well as an educated tool to have on their desk. Also included in the package is a free online resource for testing and additional information.

The understanding of pig genetics and genomics has advanced significantly in recent years, creating fresh insights into biological processes. This comprehensive reference work discusses pig genetics and its integration with livestock management and production technology to improve performance. Fully updated throughout to reflect advances in the subject, this new edition also includes new information on genetic aspects of domestication, colour variation, genomics and pig breeds, with contributions from international experts active in the field.

Why do males and females frequently differ so markedly in body size and morphology?
Sex, Size, and Gender Roles is the first book to investigate the genetic, developmental, and physiological basis of sexual size dimorphism found within and among the major taxonomic groups of animals. Carefully edited by a team of world-renowned specialists in the field to ensure a coherence of style and approach between chapters, it presents a compendium of studies into the evolution, adaptive significance, and developmental basis of gender differences in body size and morphology. Adaptive hypotheses allude to gender-specific reproductive roles and associated differences in trophic ecologies, life history strategies, and sexual selection. This "adaptationist" approach is balanced by more mechanistic studies of the genetic, developmental and physiological basis of sexual size dimorphism to provide a comprehensive and authoritative overview of the subject. Throughout the volume the emphasis is on sexual dimorphism in overall size; however, the scope of enquiry encompasses gender differences in body shape, the size and structure of secondary sexual characteristics, patterns of growth (ontogeny), and patterns of gene regulation.
This advanced, research level text is suitable for graduate level students and researchers in the fields of evolutionary biology, behavioral ecology, physiology, developmental biology, and genetics. It will also be of relevance and use to non-biologists from fields such as anthropology and gender studies.

This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index to nutritional condition in birds. The author has coined the term ptilochronology (literally. 'the study of feather time') to describe this technique, which relies on the fat that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies of avian evolution, ecology, and conservation biology. the author reviews this work, chronicles the various criticisms that have been amde, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguard against invalid results. a final chapter summarises this new technique's contribution to avian biology, and suggests potential applications and a future research agenda. an appendix details specific measurements and describes the methodology associated with ptilochronology.
Ptilochronology provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.

Pursuing the questions of how we learn and how memory is made, Edward Kosower introduces a novel and rich approach to connecting molecular properties with the biological properties that enable us to write and read, to create culture and ethics, and to think. Here he examines what happens within a single cell in reaction to external stimuli, and shows the parallels between single cell and multicellular responses. To address the problem of "learning," Kosower explains the molecular mechanisms of responses to input from taste, olfactory, and visual receptors. He then shows how these and other processes serve as the basis for memory. This study covers such signals for the molecular process of learning as pheromones (the molecular signals mediating behavior), light (activates the G-protein receptor, rhodopsin), and acetylcholine (opens the nicotinic acetylcholine receptor). Kosower's discussion of the structure and function of these complex molecules has direct implications for such areas as molecular neurobiology, bioorganic chemistry, and drug design, in elucidating approaches to the structure of drug targets.
