With up to a quarter of all insect species heading towards
extinction over the next few decades, there is now a pressing need
to summarize the techniques available for measuring insect
diversity in order to develop effective conservation strategies.
Nutrition spans a wide range of mechanisms from acquisition of food to digestion, absorption and retention of energy substrates, water and other nutrients. Nutritional principles have been applied to improving individual health, athletic performance and longevity of humans and of their companion animals, and to maximizing agricultural efficiency by manipulating reproduction or growth of tissues such as muscle, hair or milk in livestock. Comparative nutrition borrows from these tra- tional approaches by applying similar techniques to studies of ecology and physiology of wildlife. Comparative approaches to nutrition integrate several levels of organization because the acquisition and flow of energy and nutrients connect individuals to populations, populations to communities, and communities to ecosystems. Integrative Wildlife Nutrition connects behavioral, morphological and biochemical traits of animals to the life history of species and thus the dynamics of populations. An integrated approach to nutrition provides a practical framework for understanding the interactions between food resources and wildlife popu- tions and for managing the harvest of abundant species and the conservation of threatened populations. This book is for students and professionals in animal physiology and ecology, conservation biology and wildlife management. It is based on our lectures, dem- strations and practical classes taught in the USA, Canada and Australia over the last three decades. Instructors can use Integrative Wildlife Nutrition as a text in wildlife and conservation biology programs, and as a reference source for related courses in wildlife ecology.
Overviews of biochemical, genetic, and molecular perspectives of plant-insect interactions with added emphasis on bioinformatic, genomic, and transcriptome analysis are comprehensively treated in this book. It presents the agro-ecological and evolutionary aspects of plant-insect interactions with an exclusive focus on the climate change effect on the resetting of plant-insect interactions. A valuable resource for biotechnologists, entomologists, agricultural scientists, and policymakers, the book includes theoretical aspects as a base toward real-world applications of holistic integrated pest management in agro-ecosystems.
This book introduces the reader to the power of observation before,
and sometimes instead of, experimental manipulation in the study of
animal behavior. It starts with simple and easily accessible
methods suitable for student projects, before going on to
demonstrate the possibilities that now exist for far more
sophisticated analyses of observational data. At a time when animal
welfare considerations are attracting political as well as
scientific debate, the potential for non-intrusive studies on
animals is being increasingly recognized. Observation emerges as a
valuable alternative approach, often yielding highly informative
results in situations (such as on zoos, farms or for wild animals)
where more invasive experimental techniques would be undesirable,
unethical or just plain impossible. However, to justify its place
alongside experimentation as a rigorous scientific method,
observation needs to be just as disciplined and systematic and have
just as much attention paid to project design in the way that
observations are made and recorded.

The foraging mode of lizards has been a central theme in guiding research in lizard biology for three decades. Foraging mode has been shown to be a pervasive evolutionary force molding the diet, ecology, behavior, anatomy, biomechanics, life history and physiology of lizards. This volume reviews the state of our knowledge on the effects of foraging mode on these and other organismal systems to show how they have evolved, over a wide taxonomic survey of lizard groups. The reviews presented here reveal the continuous nature of foraging strategies in lizards and snakes, providing the reader with an up-to-date review of the field, and will equip researchers with new insights and future directions for the sit-and-wait vs. wide foraging paradigm. This will serve as a reference book for herpetologists, evolutionary biologists, ecologists and animal behaviorists.
Recent progress in the field of wildlife disease ecology demonstrates that infectious disease plays a crucial role in the lives of wild animals. Parasites and pathogens should be especially important for social animals in which high contact among individuals increases the potential for disease spread. As one of the best studied mammalian groups, primates offer a unique opportunity to examine how complex behaviours (including social organization) influence the risk of acquiring infectious diseases, and the defences used by animals to avoid infection. This book explores the correlates of disease risk in primates, including not only social and mating behaviour but also diet, habitat use, life history, geography and phylogeny. The authors examine how a core set of host and parasite traits influence patterns of parasitism at three levels of biological organization: among individuals, among populations, and across species. A major goal is to synthesize, for the first time, four disparate areas of research: primate behavioural ecology, parasite biology, wildlife epidemiology, and the behavioural and immune defences employed by animals to counter infectious disease. Throughout, the authors provide an overview of the remarkable diversity of infectious agents found in wild primate populations. Additional chapters consider how knowledge of infectious diseases in wild primates can inform efforts focused on primate conservation and human health. More generally, this book identifies infectious disease as an important frontier in our understanding of primate behaviour and ecology. It highlights future challenges for testing the links between host and parasite traits, including hypotheses for the effects of disease on primate social and mating systems.
A witty and informative account that busts the myths about Britain's most captivating butterfly species. When summer is at its zenith and the sallow foliage develops a bluish tinge, a giant butterfly – beautiful, bold and brazen – flies powerfully over the tree canopy. Females of this species, wary yet determined, haunt the sallow thickets, depositing their eggs, while the males establish treetop territories and descend to the woodland floor in search of indelicacies to feed upon. Mysterious, elusive and enthralling in equal measure, this is the butterfly that Victorian collectors yearned for above all others: His Imperial Majesty, the Purple Emperor. A wondrous enigma, the Purple Emperor is our most elusive and least-known butterfly – we glimpse it only through fissures in its treetop world, yet this giant insect has fascinated us for centuries and has even inspired its own 'Emperoring' language. Matthew Oates became captivated by the Purple Emperor following his first sighting as a boy. He has studied it assiduously ever since, devoting his life to trying to unravel the Emperor's secrets. His Imperial Majesty takes us on a journey, beginning with a dalliance into the bizarre history of our engagement with the butterfly, with daring doings and gross eccentricities from the Victorian and Edwardian eras. Subsequent chapters explore all aspects of this remarkable butterfly's life cycle, including behaviour, habitat preferences, life history and conservation, all relayed in Matthew's unique, informative and witty style. Not so long ago, our knowledge of the Emperor was largely based on a blend of mythology and assumption. This book dispels the fabrications and reveals all about the Purple Emperor – the king of British butterflies.
Checkerspot butterflies have been used as an extraordinarily successful model system for more than four decades. This volume presents the first synthesis of the broad range of studies of that system as conducted in Ehrlich's research group in Stanford, in Hanski's research group in Helsinki and elsewhere. Ehrlich's long - term research project on Edith's checkerspot helped establish an intergrated disipline of population biology in the 1960s and ever since has contributed many fundamental insights into the ecological and evolutionary dynamics of populations. Hanski's and his associates' work an the Glanville fritillary for the past 14 years has been instrumental in establishing the field of metapopulation biology and showing how theoretical and empirical work can be effectively combined in the same project.
Group living is a widespread phenomenon amongst animals and has attracted considerable attention in a number of different contexts. This book focuses on the unifying concepts regarding group behaviour that have been developed over the last two decades. The authors discuss the mechanisms that govern the evolution and maintenance of grouping behaviour throughout the animal kingdom, and the factors that control observed group size and group composition in particular situations. Although the book's emphasis is on the elaboration of a conceptual framework, extensive examples and case studies illustrate the diversity of grouping phenomena across taxonomic boundaries, and demonstrate the general applicability of the concepts involved. Living in Groups will familiarize the reader with the latest ideas on the ecology and evolution of group-living animals, providing a summary and critical synthesis of the extensive and diverse literature on the subject.
The ability of species to migrate has interested ecologists for many years. Now that so many species and ecosystems face major environmental change, the ability of species to adapt to these changes by dispersing, migrating, or moving between different patches of habitat can be crucial to ensuring their survival. This book provides a timely and wide-ranging overview of the study of dispersal and incorporates much of the latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species and community levels are considered. The potential of new techniques and models for studying dispersal, drawn from molecular biology and demography, is also explored. Perspectives and insights are offered from the fields of evolution, conservation biology and genetics. Throughout the book, theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible.
Harriers are a world-wide group of birds of prey whose mating systems, population dynamics, and evolution are well-studied. This is the first book to synthesise and analyse the masses of data on the behavioural ecology of harriers. It offers an intriguing comparison of breeding systems among harriers in the northern and southern hemispheres, and includes a new phylogeny of the harriers, based on the most recent DNA findings. It is illustrated throughout with original line drawings of these impressive birds.
What hope remains for Africa's black rhinos? This book addresses that question by mixing local people and attitudes with biology and adventure, while describing the challenges of doing ecological fieldwork in a difficult setting, accompanied by a small child. It moves beyond typical nature studies by featuring real world components of conservation - the delicate mix of western and economic influences, and personal commitment.
Teleost (bony) fishes represent the most abundant taxonomic group of vertebrates. They are found in all conceivable types of aquatic environment and are extremely diverse behaviourally. Behavioural ecology of teleost fishes reviews the recent advances in knowledge of behavioural strategies and tactics of habitat selection and space use, foraging, predator avoidance and evasion, and reproduction among the teleost fishes. It proposes new directions and approaches for future research. It also considers the impact of individual behaviour on population and community ecology.
Within the current context of global interest in biological diversity, this is a timely review of the most recent research into the evolutionary origins of biological diversity and the processes of speciation, from a stellar cast of contributors. The chapters in this book explore the question of how variation arises within species; some emphasize the ecological and behavioural basis of differentiation; others argue for the role of natural selection in generating speciation. Several chapters focus on the important emerging links between sexual selection, sexual conflict, and population differentiation. The final chapters explore the fossil record for data on the origination of species diversity - and extinctions - in the past. This book is a must-have for all researchers and graduate students in the biological sciences who want to be abreast of the latest thinking on the evolution of biological diversity.
Our understanding of the way in which animals know how, when, and where to orient and navigate around their environment has grown considerably over the last decade. Movement can vary from displacement in the immediate environment to the long-distance migration of salmon or swallows. How animals find their way around is both immensely variable and controversial - what cues they use and how their senses are involved, how much they remember, to what extent they rely on instinctive information or learning. Behaviour, ecology, and neurophysiology are all implicated and have been investigated in a wide range of organisms by researchers all over the world. Individual authors, all eminent specialists within their fields, have been asked to present reviews of the material in which they are most familiar and to speculate about future directions in the field.
Obligatory brood parasites are birds that reproduce by laying their eggs in the nests of other species. This book discusses the ecological and evolutionary aspects of this remarkable behavioural adaptation.
Most animals are invertebrates, yet conservation managers and practitioners know very little about their biology, or how to study and survey them adequately in the field. Invertebrate Surveys for Conservation is a comprehensive guide to the ecological methods used to survey invertebrate animals in terrestrial, freshwater, and marine environments. Containing practical advice and discussion on optimal sampling methods, and on how to interpret samples effectively for practical conservation assessment, this book will be an essential tool for anyone involved in conservation biology or ecology.
In the search for snakebite antidotes, the ecology and evolution of venomous snakes is of critical importance. This book presents a multidisciplinary approach to venomous snake research, as well as focusing on the medical aspects of snake venoms and the effects of snakebites. Herpetology is a growing subject, and this book will appeal to the ever-increasing number of amateur snake enthusiasts. The book will also be an essential reference work for researchers involved in any aspect of venomous snake research, as well as those interested in the broader fields of ecology and evolution.
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.
Population dynamics and animal behaviour are two subjects which have developed almost independently, despite widespread acceptance of the idea that they must be related. This book provides a novel framework for combining these two subjects and then shows how to consider a range of conservation issues. It is aimed at students and researchers in animal behaviour, population ecology, and conservation biology.
Addressing general readers and biologists, Mark Denny shows how the physics of fluids (in this case, air and water) influences the often fantastic ways in which life forms adapt themselves to their terrestrial or aquatic "media."
Bats are the only true flying mammals and account for about a quarter of all mammal species. The Megochiroptera (flying foxes, fruit bats) are larger animals than the Microchiroptera which can be quite small, and the two groups have very different feeding habits. Zoologists are currently debating whether they are even closely related, thus creating a body of research as diverse as the bats themselves. This book covers many aspects of bat biology, including their evolutionary origins, roles in ecosystems, reproductive biology, foraging behaviour, hibernation, and genetics, all of which will interest both professional and amateur naturalists.

ecosystem aspects of insect ecology To access the artwork from the book, please visit: http: //www.blackwellpublishing.com/speightinsects.
The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application. |
