Insects are the most ecologically important multicellular heterotrophs in terrestrial systems. They play critical roles in ecological food webs, remain devastating agricultural and medical pests, and represent the most diverse group of eukaryotes in terms of species numbers. Their dominant role among terrestrial heterotrophs arises from a number of key physiological traits, and in particular by the developmental and evolutionary plasticity of these traits. Ecological and Environmental Physiology of Insects presents a current and comprehensive overview of how the key physiological traits of insects respond to environmental variation. It forges conceptual links from molecular biology through organismal function to population and community ecology. As with other books in the Series, the emphasis is on the unique physiological characteristics of the insects, but with applications to questions of broad relevance in physiological ecology. As an aid to new researchers on insects, it also includes introductory chapters on the basics and techniques of insect physiology ecology.

This book presents a readable account of butterfly behaviour, based on field observations, great photographs and the latest research. The main focus is on courtship and mating - including perching, searching and territorial behaviour - but to understand these subjects it is necessary to explain how mates are chosen and this requires sections on wing colours and patterns. A chapter on butterfly vision is also essential in terms of how butterflies see the world and each other. There have been exciting discoveries in all of these fields in recent years, including: butterfly vision (butterfly photoreceptors), wing patterns (molecular biology), wing colouration (structural colours and nano-architecture), mating strategies and female choice (ecology and behaviour).

Quaggas were beautiful pony-sized zebras in southern Africa that had fewer stripes on their bodies and legs, and a browner body coloration than other zebras. Indigenous people hunted quaggas, portrayed them in rock art, and told stories about them. Settlers used quaggas to pull wagons and to protect livestock against predators. Taken to Europe, they were admired, exhibited, harnessed to carriages, illustrated by famous artists and written about by scientists. Excessive hunting led to quaggas' extinction in the 1880s but DNA from museum specimens showed rebreeding was feasible and now zebras resembling quaggas live in their former habitats. This rebreeding is compared with other de-extinction and rewilding ventures and its appropriateness discussed against the backdrop of conservation challenges-including those facing other zebras. In an Anthropocene of species extinction, climate change and habitat loss which organisms and habitats should be saved, and should attempts be made to restore extinct species?

In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults. The book is extensively illustrated with original diagrams and models, all of which have detailed legends, produced to enhance a broader understanding, and to provide templates for future research. It includes a detailed bibliography and glossary providing an essential gateway to the extensive literature on butterfly biology. Butterfly Biology Systems is essential reading for graduate students and researchers in insect ecology, evolution, behaviour and conservation. It will also be of great value to anyone interested in butterflies. Introduces a systems approach to butterfly biology Includes succinct reviews of the key interrelationships in butterfly life history and behaviour Illustrates more than 100 models to advance research into butterfly biology systems

The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data.

"Research Techniques in Animal Ecology" is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be used when future conditions are unpredictable due to feedbacks from the behavior of other individuals. This book provides a comprehensive introduction to state- and prediction-based theory, or SPT, a powerful new approach to modeling trade-off behaviors in contexts such as individual-based population models where feedbacks and variability make optimization impossible. Modeling Populations of Adaptive Individuals features a wealth of examples that range from highly simplified behavior models to complex population models in which individuals make adaptive trade-off decisions about habitat and activity selection in highly heterogeneous environments. Steven Railsback and Bret Harvey explain how SPT builds on key concepts from the state-based dynamic modeling theory of behavioral ecology, and how it combines explicit predictions of future conditions with approximations of a fitness measure to represent how individuals make good-not optimal-decisions that they revise as conditions change. The resulting models are realistic, testable, adaptable, and invaluable for answering fundamental questions in ecology and forecasting ecological outcomes of real-world scenarios.

This revised and reorganized text is designed for a standard forest ecology course for undergraduates in forestry, natural resources, environmental science, environmental ecology, and field ecology programs. Provides an eminently current perspective on the material by emphasizing forest ecosystems using a landscape-ecosystem or geo-ecosystem approach. Written by both field teachers and researchers of forest ecology and practitioners of forest ecology in both public and private arenas. Treats traditional plant ecology topics of community, succession, biota from a landscape ecosystem perspective, also emphasizes earth science.

In a work that will interest researchers in ecology, genetics, botany, entomology, and parasitology, Warren Abrahamson and Arthur Weis present the results of more than twenty-five years of studying plant-insect interactions. Their study centers on the ecology and evolution of interactions among a host plant, the parasitic insect that attacks it, and the suite of insects and birds that are the natural enemies of the parasite. Because this system provides a model that can be subjected to experimental manipulations, it has allowed the authors to address specific theories and concepts that have guided biological research for more than two decades and to engage general problems in evolutionary biology.

The specific subjects of research are the host plant goldenrod ("Solidago"), the parasitic insect "Eurosta solidaginis" ("Diptera: Tephritidae") that induces a gall on the plant stem, and a number of natural enemies of the gallfly. By presenting their detailed empirical studies of the "Solidago-Eurosta" natural enemy system, the authors demonstrate the complexities of specialized enemy-victim interactions and, thereby, the complex interactive relationships among species more broadly. By utilizing a diverse array of field, laboratory, behavioral, genetic, chemical, and statistical techniques, Abrahamson and Weis present the most thorough study to date of a single system of interacting species. Their interest in the evolutionary ecology of plant-insect interactions leads them to insights on the evolution of species interactions in general. This major work will interest anyone involved in studying the ways in which interdependent species interact.

Synthesizing studies of parental care in a wide variety of animals, this book is the first attempt to provide general answers to the following important questions: Why does the extent of parental care vary so widely between species? Why do only females care for eggs and young in some animals, only males in others, and both parents in a few? To what extent is parental care adjusted to variation in its benefits to offspring and its costs to parents? How do parents divide their resources between their sons and daughters? In this book separate chapters examine the evolution of variation in egg and neonate size, of viviparity and other forms of bearing, and of differences in the duration of incubation, gestation, and lactation. The book reviews theoretical and empirical predictions concerning the evolution of parental care and examines the extent to which these are supported by empirical evidence. The author examines the distribution of parental care among offspring, reviews the empirical evidence that parents invest to different extents in their sons and daughters, and discusses the degree to which parents manipulate the sex ratio of their progeny in relation to the availability of resources.

The Heliconius butterflies are one of the classic systems in evolutionary biology and have contributed hugely to our understanding of evolution over the last 150 years. Their dramatic radiation and remarkable mimicry has fascinated biologists since the days of Bates, Wallace, and Darwin. The Ecology and Evolution of Heliconius Butterflies is the first thorough and accessible treatment of the ecology, genetics, and behaviour of these butterflies, exploring how they offer remarkable insights into tropical biodiversity. The book starts by outlining some of the evolutionary questions that Heliconius research has helped to address, then moves on to an overview of the butterflies themselves and their ecology and behaviour before focussing on wing pattern evolution, and finally, speciation. Richly illustrated with 32 colour plates, this book makes the extensive scientific literature on Heliconius butterflies accessible to a wide audience of professional ecologists, evolutionary biologists, entomologists, and amateur collectors.

Widespread across open lands and cities of Europe, Africa, and Asia, the common kestrel (Falco tinnunculus) is one of the most abundant and studied birds of prey. This book brings together and synthesises the results of research on kestrels for professional ornithologists and scientists that seek to consolidate a vast body of literature. It is also a reference for those readers who may not have the depth of scientific knowledge to navigate new fields of scientific enquiry. It examines many aspects of the species' biology, from the reproductive strategies to the behavioural and demographic adaptations to changes of environmental conditions. It also discusses the roles of physiology and immunology in mediating the adaptability of kestrels to the ongoing environmental changes with a particular focus on contaminants. This volume presents new and exciting avenues of research on the ecology and behaviour of the common kestrel.

Islands and Snakes contains 13 chapters describing ecological systems with foci on snakes and their ecological roles on islands around the world. Each chapter is written by one or more authors who is an authority on that particular system. Summaries of research on the various islands are written in a narrative manner that includes science as well as personal insights in easily understood language. These varied vignettes of science feature islands around the world, and in all cases, fantastic species of snakes and their roles in the community of insular organisms in which they occur. Both challenges and opportunities associated with island life are discussed, as well as the unique attributes of snakes and their conservation as unique and important parts of nature. Chapters include colorful photographs and illustrations, and collectively they convey information on topics that include ecology, behavior, biogeography, physiology, adaptation, and evolutionary biology. An introductory chapter presents a review and perspective on the historical importance of island ecology and how snakes have contributed to our understanding of evolution and adaptation. The other chapters focus on snakes inhabiting islands associated with Asia, Australia, South America, North America, the Caribbean, and Europe. The final chapter features the unique "table top islands" or tepuis of South America as examples of ecological islands where elements of biota have become isolated by geographic features of landscape similarly to oceanic islands.

Mammals are the so-called "pinnacle" group of vertebrates, successfully colonising virtually all terrestrial environments as well as the air (bats) and sea (especially pinnipeds and cetaceans). How mammals function and survive in these diverse environments has long fascinated mammologists, comparative physiologists and ecologists. Ecological and Environmental Physiology of Mammals explores the physiological mechanisms and evolutionary necessities that have made the spectacular adaptation of mammals possible. It summarises our current knowledge of the complex and sophisticated physiological approaches that mammals have for survival in a wide variety of ecological and environmental contexts: terrestrial, aerial, and aquatic. The authors have a strong comparative and quantitative focus in their broad approach to exploring mammal ecophysiology. As with other books in the Ecological and Environmental Physiology Series, the emphasis is on the unique physiological characteristics of mammals, their adaptations to extreme environments, and current experimental techniques and future research directions are also considered. This accessible text is suitable for graduate level students and researchers in the fields of mammalian comparative physiology and physiological ecology, including specialist courses in mammal ecology. It will also be of value and use to the many professional mammologists requiring a concise overview of the topic.

This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses. The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.

The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.

Human-wildlife conflict (HWC) has classically been defined as a situation where wildlife impacts humans negatively (physically, economically, or psychologically), and where humans likewise negatively impact wildlife. However, there is growing consensus that the conflict between people about wildlife is as important as the conflict between people and wildlife. HWC not only affects the conservation of one species in a particular geographic area, but also impacts the willingness of an individual, a community, and wider society to support conservation programs in general. This book explores the complexity inherent in these situations, covering the theory, principles, and practical applications of HWC work, making it accessible and usable for conservation practitioners, as well as of interest to researchers more concerned with a theoretical approach to the subject. Through a series of case studies, the book's authors and editors tackle a wide variety of subjects relating to conflict, from the challenges of wicked problems and common pool resources, to the roles that storytelling and religion can play in conflict. Throughout the book, the authors work with a Conservation Conflict Transformation (CCT) approach, adapted from the peacebuilding field to address the reality of conservation today. The authors utilise one of CCT's key analytic components, the Levels of Conflict model, as a tool to provide insight into their case studies. Although the examples discussed are from the world of marine conservation, the lessons they provide are applicable to a wide variety of global conservation issues, including those in the terrestrial realm. Human-Wildlife Conflict will be essential reading for graduate students and established researchers in the field of marine conservation biology. It will also be a valuable reference for a global audience of conservation practitioners, wildlife managers, and other conservation professionals.

Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.

Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

Over the past decade, advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments. This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms (ecological development or 'eco-devo'), and how organisms in turn alter their environments (niche construction). A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism-environment effects. This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes, ecological success, and evolutionary prospects of organisms in rapidly changing environments. Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology, evolution, and developmental biology, as well as academics and researchers in these fields.

An essential introduction to microbiome science, a new cutting-edge discipline that is transforming the life sciences This book provides an accessible and authoritative guide to the fundamental principles of microbiome science, an exciting and fast-emerging new discipline that is reshaping many aspects of the life sciences. Resident microbes in healthy animals--including humans-can dictate many traits of the animal host. This animal microbiome is a second immune system conferring protection against pathogens; it can structure host metabolism in animals as diverse as reef corals and hibernating mammals; and it may influence animal behavior, from social recognition to emotional states. These microbial partners can also drive ecologically important traits, from thermal tolerance to diet, and have contributed to animal diversification over long evolutionary timescales. Drawing on concepts and data across a broad range of disciplines and systems, Angela Douglas provides a conceptual framework for understanding these animal-microbe interactions while shedding critical light on the scientific challenges that lie ahead. Douglas explains why microbiome science demands creative and interdisciplinary thinking-the capacity to combine microbiology with animal physiology, ecological theory with immunology, and evolutionary perspectives with metabolic science. An essential introduction to a cutting-edge field that is revolutionizing the life sciences, this book explains why microbiome science presents a more complete picture of the biology of humans and other animals, and how it can deliver novel therapies for many medical conditions and new strategies for pest control.

This account of the current state of foraging theory is also a valuable description of the use of optimality theory in behavioral ecology in general. Organizing and introducing the main research themes in economic analyses of animal feeding behavior, the authors analyze the empirical evidence bearing on foraging models and answer criticisms of optimality modeling. They explain the rationale for applying optimality models to the strategies and mechanics of foraging and present the basic "average-rate maximizing" models and their extensions. The work discusses new directions in foraging research: incorporating incomplete information and risk-sensitive behavior in foraging models; analyzing trade-offs, such as nutrient requirements and the threat of being eaten while foraging; formulating dynamic models; and building constrained optimization models that assume that foragers can use only simple "rules of thumb." As an analysis of these and earlier research developments and as a contribution to debates about the role of theory in evolutionary biology. Foraging Theory will appeal to a wide range of readers, from students to research professionals, in behavioral ecology, population and community ecology, animal behavior, and animal psychology, and especially to those planning empirical tests of foraging models.

Venom research and technology has advanced greatly, rapidly transforming the area of reptile venom. Research developments-like the development of molecular systematics-provide the framework necessary to reconstruct the evolutionary history of glands and fangs. Such research developments result in a fundamental shift in scientists' understanding of venom's evolution and usefulness in therapeutic development. Startling evolutionary expansion, including the development of new protein functions, enable the development of novel drug therapies and impact the effectiveness of anti-venoms available for the treatment of humans. Venomous Reptiles And Their Toxins is a comprehensive study of the entire scope of reptile venom, from its evolution to drug design and development. This book devotes a chapter to each toxin class found in reptile venom, detailing the full trajectory of research on the toxin in question. The comprehensive synthesis of research deals with the impact that venom has had on biomedical applications and snake evolution and ecology.

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.
