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.

Remote photography and infrared sensors are widely used in the sampling of wildlife populations worldwide, especially for cryptic or elusive species. Guiding the practitioner through the entire process of using camera traps, this book is the first to compile state-of-the-art sampling techniques for the purpose of conducting high-quality science or effective management. Chapters on the evaluation of equipment, field sampling designs, and data analysis methods provide a coherent framework for making inferences about the abundance, species richness, and occupancy of sampled animals. The volume introduces new models that will revolutionize use of camera data to estimate population density, such as the newly developed spatial capture–recapture models. It also includes richly detailed case studies of camera trap work on some of the world’s most charismatic, elusive, and endangered wildlife species. Indispensible to wildlife conservationists, ecologists, biologists, and conservation agencies around the world, the text provides a thorough review of the subject as well as a forecast for the use of remote photography in natural resource conservation over the next few decades.

A look at how wildlife professionals can modernize their approaches to habitat and population management with a fresh take on animal ecology. How can we maximize the probability that a species of wild animal will persist into the future? This audacious book proposes that advancing animal ecology—and conservation itself—demands that we reenvision our basic understanding of how animals interact with their environments and with each other. Synthesizing where we are and where we need to go with our studies of animals and their environs, Foundations for Advancing Animal Ecology asserts that studies of animal ecology should begin with a focus on the behaviors and characteristics of individual organisms. The book examines • the limitations of classic approaches to the study of animal ecology • how organisms organize into collections, such as breeding pairs, flocks, and herds • how the broader biotic and abiotic environment shapes animal populations, communities, and ecosystems • factors underlying the distribution and abundance of species through space and time • the links between habitat and population • why communication between researchers and managers is key • specific strategies for managing wild animal populations and habitats in an evolutionary and ecosystem context Throughout, the authors stress the importance of speaking a common and well-defined language. Avoiding vague and misleading terminology, they argue, will help ecologists translate science into meaningful and lasting actions in the environment. Taking the perspective of the organism of interest in developing concepts and applications, the authors always keep the potentially biased human perspective in focus. A major advancement in understanding the factors underlying wildlife-habitat relationships, Foundations for Advancing Animal Ecology will be an invaluable resource to professionals and practitioners in natural resource management in public and private sectors, including state and federal agencies, non-governmental organizations, and environmental consultants.

Charles Elton was one of the founders of ecology, and his Animal Ecology was one of the seminal works that defined the field. In this book Elton introduced and drew together many principles still central to ecology today, including succession, niche, food webs, and the links between communities and ecosystems, each of which he illustrated with well-chosen examples. Many of Elton's ideas have proven remarkably prescient—for instance, his emphasis on the role climatic changes play in population fluctuations anticipated recent research in this area stimulated by concerns about global warming. For Chicago's reprint of this classic work, ecologists Mathew A. Leibold and J. Timothy Wootton have provided new introductions to each chapter, placing Elton's ideas in historical and scientific context. They trace modern developments in each of the key themes Elton introduced, and provide references to the most current literature. The result will be an important work for ecologists interested in the roots of their discipline, for educated readers looking for a good overview of the field, and for historians of science.

Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarify the consequences of global climate change, the biodiversity crisis, and pollution--often find themselves wading through an unwieldy, technically top-heavy literature. Here, William Karasov and Carlos Martínez del Rio present the first accessible and authoritative one-volume overview of the physiological and biochemical principles that shape how animals procure energy and nutrients and free themselves of toxins--and how this relates to broader ecological phenomena. After introducing primary concepts, the authors review the chemical ecology of food, and then discuss how animals digest and process food. Their broad view includes symbioses and extends even to ecosystem phenomena such as ecological stochiometry and toxicant biomagnification. They introduce key methods and illustrate principles with wide-ranging vertebrate and invertebrate examples. Uniquely, they also link the physiological mechanisms of resource use with ecological phenomena such as how and why animals choose what they eat and how they participate in the exchange of energy and materials in their biological communities. Thoroughly up-to-date and pointing the way to future research, Physiological Ecology is an essential new source for upper-level undergraduate and graduate students-and an ideal synthesis for professionals. The most accessible introduction to the physiological and biochemical principles that shape how animals use resources Unique in linking the physiological mechanisms of resource use with ecological phenomena An essential resource for upper-level undergraduate and graduate students An ideal overview for researchers

The collection of chapters in this book present the concept of matched filters: response characteristics “matching” the characteristics of crucially important sensory inputs, which allows detection of vital sensory stimuli while sensory inputs not necessary for the survival of the animal tend to be filtered out, or sacrificed. The individual contributions discuss that the evolution of sensing systems resulted from the necessity to achieve the most efficient sensing of vital information at the lowest possible energetic cost. Matched filters are found in all senses including vision, hearing, olfaction, mechanoreception, electroreception and infrared sensing and different cases will be referred to in detail.

Animal population ecology comprises the study of variations, regulation, and interactions of animal populations. This book discusses the fundamental notions and findings of animal populations on which most of the ecological studies are based. In particular, the author selects the logistic law of population growth, the nature of competition, sociality as an antithesis of competition, the mechanism underlying the regulation of populations, predator-prey interaction processes, and interactions among closely related species competing over essential resources. These are the notions that are considered to be well-established facts or principles and are regularly taught at ecology classes or introduced in standard textbooks. However, the author demonstrates that these notions are still inadequately understood, or even misunderstood, creating myths that would misguide ecologists in carrying out their studies. He delves deeply into those notions to reveal their real nature and draws a road map to the future development of ecology.

The reliability of animal signals is a central problem for evolutionary biologists. This text argues that it is maintained in several ways, relevant in different circumstances, and that biologists must learn to distinguish between them.
