This informative book, first published in 1987, presents the theories of community ecology within the context of a natural example. The text describes and examines issues in community ecology and shows how research on salamanders has helped to solve some of the problems surrounding the theories. Salamanders exist in stable populations of the kind assumed in community theory and are more appropriate than most other animals for research on the applications of that theory. The interesting and meaningful results, collected from observation on these excellent subjects posed challenges to beliefs within community ecology. Life histories of salamanders, fieldwork in distinctly differing habitats, competition, predation and evolution are discussed in an easily readable text. Professional ecologists and students of community ecology and herpetology will be interedted in the information synthesised in this book.

The view of nature as `red in tooth and claw', as a jungle in which competition and predation are the predominant themes, has long been important in both the scientific and popular literature. However, in the past decade another view has become widespread among ecologists: the idea that mutualisms--mutually beneficial interactions between species--are just as important as competition and predation. This book is one of the first to explore this theme. Ideas and theories applicable to all sorts of mutualisms are presented and, where appropriate, examined in the light of concrete data. Themes explored include: the organisms involved, both animal and plant; how specializations evolved once mutualisms formed; how mutualisms affect population dynamics and community structure; and the role of mutualisms in different environments. The book will be of special interest to ecologists and a wide range of biologists.

The result of compiling widely scattered research on fish in tropical rivers, lakes and seas. A comprehensive overview of the ecology of fish communities in freshwater as well as marine environments.

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.

This book uses fundamental ideas in dynamical systems to answer questions of a biologic nature, in particular, questions about the behavior of populations given a relatively few hypotheses about the nature of their growth and interaction. The principal subject treated is that of coexistence under certain parameter ranges, while asymptotic methods are used to show competitive exclusion in other parameter ranges. Finally, some problems in genetics are posed and analyzed as problems in nonlinear ordinary differential equations.

Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.

Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions. Because they are essential players in the carbon cycle and related processes, microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change. This second edition has been fully revised, restructured, and updated while remaining concise and accessible. It discusses the major processes carried out by viruses, bacteria, fungi, protozoa and other protists - the microbes - in freshwater, marine, and terrestrial ecosystems. The focus is on biogeochemical processes, starting with primary production and the initial fixation of carbon into cellular biomass, before exploring how that carbon is degraded in both oxygen-rich (oxic) and oxygen-deficient (anoxic) environments. These processes are in turn affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predation by various protists in soils and aquatic habitats. The book neatly connects processes occurring at the micron scale to events happening at the global scale, including the carbon cycle and its connection to climate change issues. A final chapter is devoted to symbiosis and other relationships between microbes and larger organisms. Microbes have huge impacts not only on biogeochemical cycles, but also on the ecology and evolution of more complex forms of life, including humans.

Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

In these essays that survey the burgeoning field of tropical herpetology, former students and associates pay tribute to Jay Savage's four decades of mentoring. The result is a book unlike any other available in tropical herpetology. Covering a wide array of subjects, "Ecology and Evolution in the Tropics" is the first book in more than two decades to broadly review research on tropical amphibians and reptiles. A tribute to Savage and an invaluable addition to the herpetological literature, this work will be cited for years to come.

This established textbook continues to provide a comprehensive and stimulating introduction to marine ecological concepts and processes. Based on a wealth of international teaching expertise, "An Introduction to Marine Ecology" is written to be the basis for an entire undergraduate course in marine biology or ecology. It covers the trophic, environmental and competitive interactions of marine organisms, and the effects of these on the productivity, dynamics and structure of marine systems. The strength of the book lies in its discussion of core topics which remains at the heart of the majority of courses in the subject, despite an increasing emphasis on more applied aspects.

The authors maintain the tradition of clarity and conciseness set by previous editions, and the text is extensively illustrated with colour plates, photographs and diagrams. Examples are drawn from all over the world. In this edition, the scientific content of the text has been fully revised and updated. An emphasis has been placed on human impacts, and completely new chapters have been added on fisheries, marine ecosystems, and human interference and conservation.
Completely revised and updated with a twofold increase in the number of illustrations.
Adopts a more applied approach in keeping with current teaching.
New chapters on fisheries, the marine ecosystem, conservation and pollution.
Based on a proven and successful course structure.

This book examines the mechanisms and functions of tonic immobility, the so-called death feigning behavior, or thanatosis, or animal hypnosis. The chapters cover the neurophysiological and experimental studies on insects, the functional significance of death-feigning, examination of the freezing and immobility behavior in insects through environment, physiology, genetics, and responses to ultrasound and vibration. It also covers tonic immobility and freezing behavior in fish from the perspective of vertebrates study. Tonic immobility is an interesting behavior that occurs reflexively in various animals under physical restraint by predators. The physiological mechanism of thanatosis was extensively investigated during 1960-1980. Researchers have proposed hypotheses to explain the mechanism underlying tonic immobility in vertebrates; local inhibition of the central nervous system, acceleration of the limbic system, abnormal control of the autonomic nervous system. On the other hand, the peripheral and central mechanisms of tonic immobility were intensely investigated at a behavioral and a neuronal level in stick insects and crickets. In the 1970s, behavioral ecology has shed light on the aspect of an ultimate factor for tonic immobility. Ethologists and ecologists challenged this matter in the laboratory and natural habitats, and have collected evidence for its functional roles using mainly insects such as beetles, moths, locusts. More recently, studies of tonic immobility in humans are drawing attention, as clinicians are trying to explain the defencelessness of rape victims from the viewpoint of animal hypnosis. This timely publication provides an understanding of the past and present research of the mechanisms and functions of tonic immobility. This book is intended for researchers and undergraduate/ graduate students in the field of zoology including physiology, ethology, ecology, and human behavior. It will also appeal to the public audience who has an interest in animal behavior, including human behavior.

The first comprehensive volume exclusively on marine cone snails, this book provides descriptions of over 100 species of hazardous marine snails along with their biological and ecological characteristics; the characteristics of conotoxins; information on cone snail injuries and their treatment along with prevention measures; and the therapeutic and medicinal value of conotoxins, including as a powerful nonaddictive painkiller, an epilepsy drug, and more. Over 275 color illustrations accompany the text for easy identification.

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.

In 1968 the residents of Lovell, Wyoming, began the work of saving the Pryor Mountain Mustang, a breed of horse with a genetic link dating back to the sixteenth-century Spanish conquistadores' horses. In this moving case study, Christine Reed shows how, through a grassroots campaign, these residents championed the creation of the first federal public wild horse range. Crucial to this provocative analysis of local-federal cooperation is the relationship that grew between the Lovell advocates, the Bureau of Land Management, and the National Park Service. Long before there were federal laws passed to protect wild horse herds across the western states, the Pryor Mountain Mustang was preserved through the cooperative efforts of local residents and federal officials. Saving the Pryor Mountain Mustang explores the unique and ongoing relationship between locals and the federal government, highlighting the Lovell citizens' philosophy of cooperation instead of the typical mistrust that exists between wild horse advocates and federal agencies. The book provides a rich analysis of how a determined group of people saved an endangered wild horse herd. The book will have wide appeal to wild horse activists, scholars of local and federal governance, and western history enthusiasts.

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.

Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis.

With its iconic appearance and historic popular appeal, the giraffe is the world's tallest living terrestrial animal and the largest ruminant. Recent years have seen much-needed new research undertaken to improve our understanding of this unique animal. Drawing together the latest research into one resource, this is a detailed exploration of current knowledge on the biology, behaviour and conservation needs of the giraffe. Dagg highlights striking new data, covering topics such as species classification, the role of infrasound in communication, biological responses to external temperature changes and motherly behaviour and grief. The book discusses research into behaviour alongside practical information on captive giraffe, including diet, stereotypical behaviour, ailments and parasites, covering both problems and potential solutions associated with zoo giraffe. With giraffe becoming endangered species in Africa, the book ultimately focuses on efforts to halt population decline and the outlook for conservation measures.

As natural habitat continues to be lost and the world steadily becomes more urbanized, biologists are increasingly studying the effect this has on wildlife. Birds are particularly good model systems since their life history, behaviour, and physiology are especially influenced by directly measurable environmental factors such as light and sound pollution. It is therefore relatively easy to compare urban individuals and populations with their rural counterparts. This accessible text focuses on the behavioural and physiological mechanisms which facilitate adaptation and on the evolutionary process that ensues. It discusses topics such as acoustics, reproductive cues, disease, and artificial feeding, and includes a series of case studies illustrating cutting edge research on these areas. Avian Urban Ecology is suitable for professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution, and conservation. It will also be of relevance and use to a more general audience of urban ecologists and conservation biologists.

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history-and our part in it-is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Inspired by a passion for the lost Pleistocene giants, some scientists advocate bringing elephants and cheetahs to the Great Plains as stand-ins for their extinct native brethren. By reintroducing big browsers and carnivores to North America, they argue, we could rescue some of the planet's most endangered animals while restoring healthy prairie ecosystems. Critics, including biologists enmeshed in the struggle to restore native species like the gray wolf and the bison, see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

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 2007 volume reviews the 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 a review of the field, and will equip researchers with fresh insights and 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.

Published in 2006, Chemical Ecology of Vertebrates was the first book to focus exclusively on the chemically-mediated interactions between vertebrates including fish, amphibians, reptiles, birds and mammals, and other animals and plants. Reviewing research in three core areas - pheromones (where the interactions are between members of the same species), interspecific interactions involving allomones (where the sender benefits) and kairomones (where the receiver benefits), it pulls together information from widely scattered technical literature in many different disciplines into a coherent whole. Chapters on the environment, properties of odour signals, and production and release of chemosignals set the stage for discussion of more complex behavioural topics. While the main focus is ecological, dealing with behaviour and interactions in the field, it also covers chemoreception, orientation and navigation, the development of behaviour and the practical applications of chemosignals.

Acanthocephalans, or spiny-headed worms, are endoparasites found in almost all marine, freshwater and terrestrial systems. They infect a huge range of definitive and intermediate hosts during their life cycles, including both vertebrates and arthropods. This volume, first published in 2006, examines the distribution and abundance of the Acanthocephala, and uses this ecological information to reveal the group's enormous survival success. It discusses how the acanthocephalans have evolved differently to all other groups of parasites, and represent a distinct and alternative pathway of parasite evolution and host parasite-interactions. Written for graduate students and researchers in parasitology, ecology and zoology or anyone interested in reading about parasite ecology and evolution.

To provide useful and meaningful information, long-term ecological programs need to implement solid and efficient statistical approaches for collecting and analyzing data. This volume provides rigorous guidance on quantitative issues in monitoring, with contributions from world experts in the field. These experts have extensive experience in teaching fundamental and advanced ideas and methods to natural resource managers, scientists, and students. The chapters present a range of tools and approaches, including detailed coverage of variance component estimation and quantitative selection among alternative designs; spatially balanced sampling; sampling strategies integrating design- and model-based approaches; and advanced analytical approaches such as hierarchical and structural equation modelling. Making these tools more accessible to ecologists and other monitoring practitioners across numerous disciplines, this is a valuable resource for any professional whose work deals with ecological monitoring.
