First published in 1983, the second edition of this informative book remains the most comprehensive and current overview of the behavioral traits and adaptations of horses. The book integrates findings from hundreds of international researchers to provide the reader a factual synthesis of the behavior of domestic and feral horses. Building on the strengths of the first edition, the author has thoroughly updated coverage of horse ancestry, development, perception, learning, play, social behavior, behavioral manipulation, maintenance activities, and sexual behavior. In this second edition more emphasis has been given to animal husbandry and management. Additionally, the second edition includes an all-new section on ecological influences on activity patterns, habitat utilization, social behavior and reproduction. An expanded section on applied ethology provides behavioral considerations for management and insight regarding the behavioral indicators of horse health and well being. This is followed with an updated appendix listing behavioral symptoms and possible causes. The text contains numerous tables and nearly 100 illustrations and photos.

The book summarizes present scientific knowledge in plant physiology with regards to plant production. The authors, mainly professors of plant physiology at agricultural universities in Czechoslovakia, present the individual fields of plant physiology with regard to the demands of agricultural practice and education of students and doctorani at these universities.
The first chapters discuss metabolism ie. photosynthesis, respiration, mineral and heterotrophic nutrition, and water regime of plants. What follows is a discussion of the physiology of plant growth, development and movements, and finally resistance of plants against unfavourable abiotic and biotic effects.
The book shows how to increase the yield of crops by manipulating photosynthesis and also studies the possible flow of photosynthetic products to the commercially valuable parts of the biomass. Rational plant production, however, cannot do without knowledge of plant nutrition and water regime as a theoretical basis for fertilization and irrigation. The reader will find this knowledge detailed as well as information about the ecological and physiological principles of the resistance of plants against drought, frost, heat, diseases and other unfavourable effects.

In the last 50 years the tiger population in Asia has plummeted from 100,000 to about 5,000. The number of tigers is dangerously low, and the conservation of the world's remaining tigers is of global concern. Now, in this volume, 40 world authorities on tigers from Asia, Europe, and North America have summarized and identified the management, conservation, and research needs for this endangered species.
A new disciplineuconservation biologyuis emerging and this book is an early contribution. It spans and unites theory, laboratory, and field studies with management practices of both the wild and captive populations.
The book is based on the international symposium held in Minnesota, discusses the tiger's systematics and taxonomy, its status both in the wild and captivity, reproductive biology, and management and conservation strategies. In addition, an entire section is devoted to a discussion of the white tiger. The tigers of Indonesia, Nepal, Siberia, and China, as well as captive tigers are discussed. Finally, the information in this book places real numbers on the remaining tiger populations, their habitat that is protected, and probabilities of these populations surviving an extinction."

Gazelles and their relatives are important game animals in Africa and Asia; they have been successfully introduced into the US and they are also kept in zoos throughout the world. The occurrence of territorial behavior and its importance for the reproduction of gazelles has been recognized for some time; thus specific information on their territorial behavior is desirable both for scientific and for practical reasons. This book provides the first concrete information on territory size and shape, duration of territorial periods, reoccupation of territories, phases of territoriality, the process of becoming territorial and of abandoning the territory, favorable and unfavorable environmental factors for territorial establishment, and territoriality as antagonist of migratory behavior. Also included are many previously unknown details of traditional territorial behavior, such as differences in the aggression of owners of territories toward (male) conspecifics of different age and social class, the structure of a marking system within a territory, etc.

Iguanas are large, primeval appearing animals that have always attracted considerable attention and sicentific study. The 30 species of iguanas are today collectively referred to as iguanines, or the subfamily Iguaninae, of the lizard family Iguanidae. This book is the result of a symposium of worldwide scientists on the world's iguanas that was held at a joint meeting of the Society of the Study of Amphibians and Reptiles and The Herpetologist's League. Over 30 recognized experts submitted their studies of these interesting reptiles, and have published what was once unknown and unpublished information. This book was a leader in its time, and still serves as a wonderful reference for scientist and student alike.

The latest research results on the roles of amino acid chelates in animal nutrition are covered in this book, with careful attention to scientific detail and accuracy. The book presents the work of 42 international contributors; and will interest nutritionists, veterinarians, and all those concerned with animal feeds and feeding programs -- particularly those supplying mineral supplements to the diet in a form which can be absorbed readily and digested properly.

Since the early 1940s, North America has been the focus of studies of free-ranging wolves. Much of Canada and most of Alaska support numerous, viable and sometimes thriving wolf populations. This comprehensive text considers the behavior and ecology of wild wolves in North America, Europe, Eurasia, Israel, and Iran. It also discusses wolf behavior in captivity and methods of conservation. This book and others in the Animal Science series have been used as textbooks in classrooms across the world.

The first major and most comprehensive synthesis of results from ecological, naturalistic behavioral, comparative psychological and humanoid language research on apes since the classic work, The Great Apes, by Robert M. and Ada Yerkes in 1929.

Topical discussions in the book are organized to show the extent of progress, including the development of new research questions, and the way our views of apes have changed as new information has become available since 1929.

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided.

This edited volume in the Theoretical Ecology series addresses the historical development and evolution of theoretical ideas in the field of ecology. Not only does it recount the history of the discipline by practitioners of the science of ecology, it includes commentary on these historical reflections by philosophers of science. Even though the theories discussed are, in many cases, are at the forefront of research, the language and approach make this material accessible to non-theoreticians. The book is structured in 5 major sections including population ecology, epidemiology, community ecology, evolutionary biology and ecosystem ecology. In each section a chapter by an eminent, experienced ecologist is complemented by analysis from a newer, cutting-edge researcher.
* Reflection on the past and future of ecology
* A historical overview of major ideas in the field of ecology
* Pairing of historical views by ecologists along with a philosophical commentary directed at the practicing scientists views by a philosopher of science.
* Historical analysis by practicing ecologists including anectodal experiences that are rarely recorded.
* Based on a very popular symposium at the 2002 Ecological Society of America annual meeting in Tucson, AZ.

It is impossible to predict the exact behavior of all biological systems and how these same systems are exemplified by patterns of complexity and regularity. Decades of research in ecology have documented how these sorts of patterns are the consequences of deceptively simple rules that determine the nature of the patterns created. Chaos in Ecology will explain how simple beginnings result in complicated results.
Chaos in Ecology is the inaugural volume of Theoretical Ecology Series. The authors of this volume have employed data from a proven model system in population dynamics. As a result, this book will be of interest to anyone interested in the ecology of populations.
It is impossible to predict the exact behavior of almost all biological systems and yet these same systems are exemplified by patterns of complexity and regularity. Decades of research in ecology have documented that these sorts of patterns are the consequence of deceptively simple rules that determine the nature of the patterns created. In essence, simple beginnings result in complicated results.
This realization is captured in the mathematical notion of "chaos" and is rendered intuitive by the oft-repeated metaphor: "A butterfly beats its wings in China and causing a thunderstorm in the Midwest." Thus, seemingly trivial initial conditions (e.g. a butterfly in China) cascade through a series of intermediate events to create a significant large-scale event (e.g. a thunderstorm).

Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination.
This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes.
Key Features
* Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy
* A world biogeographical perspective on seed dormancy and germination
* Ecophysiology of seeds with each type of dormancy
* Critical evaluation of methodology used in soil seed bank studies
* Germination ecology of plants with specialized habitat and life cycle types
* Genetic and maternal preconditioning effects on seed dormancy and germination
* Guidelines for doing ecologically-meaningful germination studies

Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined.
An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.

The use of DNA and other biological macromolecules has revolutionized systematic studies of evolutionary history. Methods that use sequences of nucleotides and amino acids are now routinely used as data for addressing evolutionary questions that, although not new questions, have defied description and analysis. The world-renowned contributors use these new methods to unravel particular aspects of the evolutionary history of birds. Avian Molecular Evolution and Systematics presents an overview of the theory and application of molecular systematics, focusing on the phylogeny and evolutionary biology of birds. New, developing areas in the phylogeny of birds at multiple taxonomic areas are covered, as well as methods of analysis for molecular data, evolutionary genetics within and between bird populations, and the application of molecular-based phylogenies to broader questions of evolution.
Key Features
* Contains authoritative contributions from leading researchers
* Discusses the utility of different molecular markers for questions of avian evolution, involving populations and higher-level taxa
* Applies molecular-based phylogenies of birds and molecular population genetics data to broad questions of organismal and molecular evolution.
* Compares and contrasts molecular and morphological data sets

To escape the constraints of water-bound reproduction, the first terrestrial vertebrates evolved a group of membranes that surround and protect developing embryos. The "amnion" is one of these membranes. It surrounds and protects in amniotic fluid, the developing embryos of birds, reptiles and mammals. Terrestrial vertebrates began to diversify and exploit their new habitats when the need to reproduce in water no longer dictated the course of their lives. Occurring in conjunction with this reproductive freedom was the evolution of non-permeable skin (to avoid cutaneous water loss), different less toxic forms of nitrogen waste and more efficient forms of locomotion and feeding. This text gives a detailed treatment of these and other changes that occurred as vertebrates completed the transition from aquatic to terrestrial life. It integrates modern systematic methods with studies of functional and physiological processes, and illustrates how studies of paleobiology can be illuminated by studies of neontology.

This practical book provides crucial information necessary to formulate diets with appropriate amounts of amino acids, minerals, and vitamins. The factors that influence how well animals obtain these critical nutrients and methods for determining bioavailability are reviewed in this comprehensive text. In addition, data from both ruminants and nonruminants are included as well as established estimates of bioavailability for particular feed stuffs and feed supplements.

Coniferous forests are among the most important of ecosystems. These forests are widespread and influence both the financial and biological health of our globe. This text focuses attention on conifers and how these trees acquire, allocate and utilize the resources that sustain this crucial productivity. An international team of experts has surveyed and synthesized the information from an expanding area of inquiry. The first half of the book describes how resources are acquired both by means of photosynthesis and through root systems. The latter half of the volume focuses upon how resources are stored and used. As conifers continue as a resource and ever increasingly important contributor to the regional and global environment sustainability, this book should help establish how much sustainability can be expected and maintained.

Conifers--pine, fir, and spruce trees--are dominant species in forests around the world. This book focuses on the physiology of conifers and how these physiological systems operate. Special consideration is devoted to the means by which ecophysiological processes influence organismal function and distribution. Chapters focus on the genetics of conifers, their geographic distribution and the factors that influence this distribution, the impact of insect herbivory on ecophysiological parameters, the effects of air pollution, and the potential impact that global climatic changes will have upon conifers. Because of the growing realization that forests have a crucial role to play in global environmental health, this book will appeal to a developing union of ecologists, physiologists and more theoretically minded foresters.

This book surveys the ways in which land dwelling arthropods deal with water in terrestrial environments. From scorpion to beetle and spider to hover fly, water is a crucial component of activity. This new synthesis and integration of recent research summarizes the ways water is managed by these diverse terrestrial invertebrates. The mechanisms, processes and structures employed by arthropods represent evolutionary innovations and compromises. Those fascinated by the limitations and opportunities represented by terrestrial lifestyles will want this new book.

This book explores ways in which systematic patterns are used to infer evolutionary processes. Among evolutionary biologists and systematists there is a constant interchange between those that study the process of evolution (e.g., mutation, selection, speciation) and those that study its patterns (e.g., variation, geographic distribution, ontogeny, phylogeny). Because patterns influence the development of theories, and processes yield patterns, it is not always easy to distinguish one from another. This book is dialectic and helps crystallize a continuing debate over the relationship of patterns to process theories.
Key Features
* Contributions by leading systematists, evolutionary biologists, and philosophers
* Illustrates the debate over how and if evolutionary processes can be inferred from systematic patterns
* Illustrates a continuing interplay between systematics and evolutionary theory

This book examines the differences and similarities in the earth system components - the ocean, atmosphere, and the land - between western portions of the northern and southern Western Hemispheres, past, present, and projected. The book carefully examines the physical and biological patterns and responses of given biomes, or ecological communities in the two regions. Special emphasis is placed on the relationship of physicial and biotic systems to biogeochemistry and the evolving biota patterns of land margins and surfaces. The text concludes with an assessment of the direct impact on humans on these biomes, giving full consideration to the land-use drivers of global change.
