The ecological literature on marsupials is dominated by descriptive natural history, and there has hitherto been little attempt at either synthesis or evolutionary interpretation. This book attempts to provide such a synthesis, by drawing on both the descriptive data base and predictions from the burgeoning literature on behavioural and evolutionary ecology. It documents the excellent potential the study of marsupials provides for resolution of theoretical questions of general importance in biology. It does this in three ways. First, by describing the impressive diversity of marsupial life history strategies and trophic roles. Second, by careful comparison with the eutherians, the scope of the marsupial radiation is used to analyse the role of developmental constraints and adaptive radiation in determining the diversification of higher taxa. Lastly, it is suggested that the accessibility of marsupial young during their obligatory pouch life facilitates measurement, manipulation and assessment of kinship not possible in other mammalian groups. Further special topics include marsupial/plant mutualism, marsupial competition and the empirical uses of mammals with simple life histories.

Covering a range of metaphors from a diverse field of sciences, from cell and molecular biology to evolution, ecology, and biomedicine, Understanding Metaphors in the Life Sciences explores the positive and negative implications of the widespread use of metaphors in the biological and life sciences. From genetic codes, programs, and blueprints, to cell factories, survival of the fittest, the tree of life, selfish genes, and ecological niches, to genome editing with CRISPR's molecular scissors, metaphors are ubiquitous and vital components of the modern life sciences. But how exactly do metaphors help scientists to understand the objects they study? How can they mislead both scientists and laypeople alike? And what should we all understand about the implications of science's reliance on metaphorical speech and thought for objective knowledge and adequate public policy informed by science? This book will literally help you to better understand the metaphorical dimensions of science.

The badgers of Wytham Woods (Oxford, UK) have been studied continuously and intensively by David Macdonald for almost 50 years (25 of them with his former student and co-author Chris Newman), generating a wealth of data pertaining to every facet of their ecology and evolution. Through a mix of accessible, highly readable prose and cutting-edge science, the authors weave a riveting scientific story of the lives of these intriguing creatures, highlighting the insights offered to science more broadly through badgers as a model system. They provide a paradigm - from population down to molecule - for a deeper understanding of mammalian behaviour, ecology, epidemiology, evolutionary biology, and conservation. The real value of this long-term study is particularly apparent with current and globally relevant challenges such as climate change, disease epidemics, and senescence. This unique dataset enables us to examine these issues in a context that only a half-century experiment can reveal. The Badgers of Wytham Woods will appeal to a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and students at all levels, governmental and non-governmental wildlife bodies, and to the natural historian fascinated by wild animals and the remarkable processes of nature they exemplify.

Rebirding takes the long view of Britain's wildlife decline, from the early taming of our landscape and its long-lost elephants and rhinos, to fenland drainage, the removal of cornerstone species such as wild cattle, horses, beavers and boar - and forward in time to the intensification of our modern landscapes and the collapse of invertebrate populations. It looks at key reasons why species are vanishing, as our landscapes become ever more tamed and less diverse, with wildlife trapped in tiny pockets of habitat. It explores how Britain has, uniquely, relied on modifying farmland, rather than restoring ecosystems, in a failing attempt to halt wildlife decline. The irony is that 94% of Britain is not built upon at all. And with more nature-loving voices than any European country, we should in fact have the best, not the most impoverished, wildlife on our continent. Especially when the rural economics of our game estates, and upland farms, are among the worst in Europe. Britain is blessed with all the space it needs for an epic wildlife recovery. The deer estates of the Scottish Highlands are twice the size of Yellowstone National Park. Snowdonia is larger than the Maasai Mara. The problem in Britain is not a lack of space. It is that our precious space is uniquely wasted - not only for wildlife, but for people's jobs and rural futures too. Rebirding maps out how we might finally turn things around: rewilding our national parks, restoring natural ecosystems and allowing our wildlife a far richer future. In doing so, an entirely new sector of rural jobs would be created; finally bringing Britain's dying rural landscapes and failing economies back to life.

What is animal welfare? Why has it proved so difficult to find a definition that everyone can agree on? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as 'health and animals having what they want', a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare. But, can we really understand what animals want? A consistent theme running through the book is that not only is it possible to establish what animals want, but that this information is vital in helping us to make sense of the long and often confusing list of welfare measures that are now in use such as 'stress' and 'feel good hormones', expressive sounds and gestures, natural behaviour, cognitive bias, and stereotypies. Defining welfare as 'health and what animals want' allows us to distinguish between measures that are simply what an animal does when it is alert, aroused, or active and those measures that genuinely allow us to distinguish between situations the animals themselves see as positive or negative. Sentience (conscious feelings of pleasure, pain, and suffering) is for many people the essence of what is meant by welfare, but studying consciousness is notoriously difficult, particularly in non-human species. These difficulties are discussed in the context of our current - and as yet incomplete - knowledge of human and animal consciousness. Finally, the book highlights some key ideas in the relationship between animal welfare science and animal ethics and shows how closely the well-being of humans is linked to that of other animals. The Science of Animal Welfare is an ideal companion for undergraduate and graduate students taking courses in animal behaviour and welfare, as well as for professional researchers, practitioners and animal welfare consultants. At the same time, it is easily understandable to non-scientists and anyone without prior knowledge but with an interest in animals and the rapidly evolving science of animal welfare.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Essential Ornithology provides the reader with a concise but comprehensive introduction to the biology of birds, one of the most widely studied taxonomic groups. The book begins by considering the dinosaur origins of birds and their subsequent evolution. Development, anatomy, and physiology are then discussed followed by chapters devoted to avian reproduction, migration, ecology, and conservation. Sections dealing with aspects of bird/human relationships and bird conservation give the book an applied context. This new edition has been thoroughly updated, providing new information from rapidly-developing fields including the avian fossil record, urban and agricultural ecology, responses to climate change, invasive species biology, technologies to track movement, avian disease, and the role of citizen scientists. There is also a greater focus on North American ornithology. Drawing extensively upon the wider scientific literature, this engaging text places the results of classical studies of avian biology alongside the most recent scientific breakthroughs. Useful case studies are presented in a concise and engaging style with the student reader foremost in mind. Key points are highlighted and suggestions for guided reading and key references are included throughout. Essential Ornithology is a companion textbook for advanced undergraduate and graduate students taking courses in avian science, as well as a useful reference for professional researchers and consultants. Amateur ornithologists will also find this book offers a scientifically rigorous and accessible overview for a more general readership.

In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects. Furthermore, in studying the effects of natural selection in generally increasing the insects' ergonomic efficiency, they go beyond the concentration of previous researchers on the physiological mechanisms of the insects and turn our attention instead to the scale and efficiency of the insects' division of labor. Recognizing that the efficiency of the insect colony is based on a complex fitting of the division of labor to many simultaneous needs, including those imposed by the distribution of resources and enemies around the nest, Professors Oster and Wilson are able to construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems. The social insects play a key role in the subject of sociobiology because their social organization is so rigid and can be related to genetic evolution. Because of this important consideration, the authors' work has consequences not only for entomology but also for general evolutionary theory.

Subsistence intensification, innovation and change have long figured prominently in explanations for the development of social complexity among foragers and horticulturalists. This set of global case studies re-examines the 'subsistence question' in light of recent research. It contrasts traditional approaches with recent archaeological research that presents human driven strategies for power, prestige, and status as causes of subsistence intensification.

Insects provide excellent model systems for understanding evolutionary ecology. They are abundant, small and relatively easy to rear, and these traits facilitate both field and laboratory experiments. This book has been developed from the Royal Entomological Society's 22nd International Symposium, held in Reading in 2003. Topics include speciation and adaptation; life history, phenotype plasticity and genetics; sexual selection and reproductive biology; insect-plant interactions; insect-natural enemy interactions and social insects.

This volume is the first scholarly book on the antelope that dominate the savanna ecosystems of eastern and southern Africa. It presents a synthesis of research conducted over a span of fifty years, mainly on the wildebeests in the Ngorongoro and Serengeti ecosystems, where eighty percent of the world's total wildebeest population lives. Wildebeest and other grazing mammals drive the ecology and evolution of the savanna ecosystem. Estes describes this process as well as detailing the wildebeest's life history, focusing on its social organization and unique reproductive system, which are adapted to the animal's epic annual migrations. He also examines conservation issues that affect wildebeest, including range-wide population declines.

When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection will be suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

Why do baby sharks, hyenas, and pelicans kill their siblings? Why do beetles and mice commit infanticide? Why are twins and birth defects more common in older human mothers? "A Natural History of Families" concisely examines what behavioral ecologists have discovered about family dynamics and what these insights might tell us about human biology and behavior. Scott Forbes's engaging account describes an uneasy union among family members in which rivalry for resources often has dramatic and even fatal consequences.

In nature, parents invest resources and control the allocation of resources among their offspring to perpetuate their genetic lineage. Those families sometimes function as cooperative units, the nepotistic and loving havens we choose to identify with. In the natural world, however, dysfunctional familial behavior is disarmingly commonplace.

While explaining why infanticide, fratricide, and other seemingly antisocial behaviors are necessary, Forbes also uncovers several surprising applications to humans. Here the conflict begins in the moments following conception as embryos struggle to wrest control of pregnancy from the mother, and to wring more nourishment from her than she can spare, thus triggering morning sickness, diabetes, and high blood pressure. Mothers, in return, often spontaneously abort embryos with severe genetic defects, allowing for prenatal quality control of offspring.

Using a broad sweep of entertaining examples culled from the world of animals and humans, "A Natural History of Families" is a lively introduction to the behavioral ecology of the family.

The identification and analysis of the particular habitat needs of a species has always been a central focus of research and applied conservation in both ecology and wildlife biology. Although these two academic communities have developed quite separately over many years, there is now real value in attempting to unify them to allow better communication and awareness by practitioners and students from each discipline. Despite the recent dramatic increase in the types of quantitative methods for conducting habitat analyses, there is no single reference that simultaneously explains and compares all these new techniques. This accessible textbook provides the first concise, authoritative resource that clearly presents these emerging methods together and demonstrates how they can be applied to data using statistical methodology, whilst putting the decades-old pursuit of analyzing habitat into historical context. Habitat Ecology and Analysis is written for senior undergraduate and graduate students taking courses in wildlife ecology, conservation biology, and habitat ecology as well as professional ecologists, wildlife biologists, conservation biologists, and land managers requiring an accessible overview of the latest methodology.

Ziel des Buches ist es, herauszuarbeiten, in welchen Bereichen autistische Menschen mit psychischen Begleiterkrankungen persoenliche Therapiebedarfe sehen und wie diese aktuell in der Autismus- Therapie bearbeitet werden koennen. Dazu wird die Forschungsfrage "Wie grenzen erwachsene Menschen mit Autismus-Spektrum-Stoerung und psychiatrischer Komorbiditat ihre Therapieanliegen zwischen sogenannter Autismus-Therapie und Psychotherapie ab und wie sehr passt das zu Sichtweise, Moeglichkeiten und Kompetenzen der Autismus-Therapie?" gestellt. Anknupfend an einen theoriebasierten Teil mit Darstellung der haufigsten Komorbiditaten bei Autismus-Spektrum-Stoerungen sowie der aktuellen Rahmenbedingungen der Psychotherapie (Leistung der Krankenversicherung) und Autismustherapie (Leistung der Eingliederungshilfe) wurde zur Beantwortung der Frage eine qualitative Untersuchung durchgefuhrt. Die Ergebnisse der Interviews zeigen, dass eine Abgrenzung der Therapieanliegen zwischen Autismus-Therapie und Psychotherapie nur bedingt gelingt. Autismus-Therapieanbieter sind und sehen sich uberwiegend nicht in der Lage, spezifisch auf psychotherapeutische Fragestellungen einzugehen, auch wenn sich die autistischen Menschen im jeweiligen autismustherapeutischen Setting uberwiegend gut aufgehoben fuhlen.

Measuring the abundance of individuals and the diversity of species are core components of most ecological research projects and conservation monitoring. This book brings together in one place, for the first time, the methods used to estimate the abundance of individuals in nature. The statistical basis of each method is detailed along with practical considerations for survey design and data collection. Methods are illustrated using data ranging from Alaskan shrubs to Yellowstone grizzly bears, not forgetting Costa Rican ants and Prince Edward Island lobsters. Where necessary, example code for use with the open source software R is supplied. When appropriate, reference is made to other widely used programs. After opening with a brief synopsis of relevant statistical methods, the first section deals with the abundance of stationary items such as trees, shrubs, coral, etc. Following a discussion of the use of quadrats and transects in the contexts of forestry sampling and the assessment of plant cover, there are chapters addressing line-intercept sampling, the use of nearest-neighbour distances, and variable sized plots. The second section deals with individuals that move, such as birds, mammals, reptiles, fish, etc. Approaches discussed include double-observer sampling, removal sampling, capture-recapture methods and distance sampling. The final section deals with the measurement of species richness; species diversity; species-abundance distributions; and other aspects of diversity such as evenness, similarity, turnover and rarity. This is an essential reference for anyone involved in advanced undergraduate or postgraduate ecological research and teaching, or those planning and carrying out data analysis as part of conservation survey and monitoring programmes.

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.

Wood ants play an ecologically dominant and conspicuous role in temperate boreal forests, making a keystone contribution to woodland ecosystem functions and processes. Wood ant taxonomy and global distributions set the scene for this text's exploration of wood ants as social insects, examining their flexible social structures, genetics, population ecology, and behaviour, from nest-mate recognition to task allocation. Wood ants' interactions with their environment and with other organisms are essential to their success: competition, predation and mutualism are described and analysed. Bringing together the expertise of ecological researchers and conservation practitioners, this book provides practical and theoretical advice about sampling and monitoring these insects, and outlines the requirements for effective conservation. This is an indispensable resource for wood ant researchers, entomologists, conservationists and ecological consultants, as well as anyone interested in social insects, keystone species and the management and conservation of forest ecosystems.

The modern ecologist usually works in both the field and laboratory, uses statistics and computers, and often works with ecological concepts that are model-based, if not model-driven. How do we make the field and laboratory coherent? How do we link models and data? How do we use statistics to help experimentation? How do we integrate modeling and statistics? How do we confront multiple hypotheses with data and assign degrees of belief to different hypotheses? How do we deal with time series (in which data are linked from one measurement to the next) or put multiple sources of data into one inferential framework? These are the kinds of questions asked and answered by "The Ecological Detective."

Ray Hilborn and Marc Mangel investigate ecological data much as a detective would investigate a crime scene by trying different hypotheses until a coherent picture emerges. The book is not a set of pat statistical procedures but rather an approach. The Ecological Detective makes liberal use of computer programming for the generation of hypotheses, exploration of data, and the comparison of different models. The authors' attitude is one of exploration, both statistical and graphical. The background required is minimal, so that students with an undergraduate course in statistics and ecology can profitably add this work to their tool-kit for solving ecological problems.

Network thinking and network analysis are rapidly expanding features of ecological research. Network analysis of ecological systems include representations and modelling of the interactions in an ecosystem, in which species or factors are joined by pairwise connections. This book provides an overview of ecological network analysis including generating processes, the relationship between structure and dynamic function, and statistics and models for these networks. Starting with a general introduction to the composition of networks and their characteristics, it includes details on such topics as measures of network complexity, applications of spectral graph theory, how best to include indirect species interactions, and multilayer, multiplex and multilevel networks. Graduate students and researchers who want to develop and understand ecological networks in their research will find this volume inspiring and helpful. Detailed guidance to those already working in network ecology but looking for advice is also included.

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.

Bright colors, enlarged fins, feather plumes, song, horns, antlers, and tusks are often highly sex dimorphic. Why have males in many animals evolved more conspicuous ornaments, signals, and weapons than females? How can such traits evolve although they may reduce male survival? Such questions prompted Darwin's perhaps most scientifically controversial idea--the theory of sexual selection. It still challenges researchers today as they try to understand how competition for mates can favor the variety of sex-dimorphic traits. Reviewing theoretical and empirical work in this very active field, Malte Andersson, a leading contributor himself, provides a major up-to-date synthesis of sexual selection.

The author describes the theory and its recent development; examines models, methods, and empirical tests; and identifies many unsolved problems. Among the topics discussed are the selection and evolution of mating preferences; relations between sexual selection and speciation; constraints on sexual selection; and sex differences in signals, body size, and weapons. The rapidly growing study of sexual selection in plants is also reviewed. This volume will interest students, teachers, and researchers in behavioral ecology and evolutionary biology.

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.
