R2,203 Discovery Miles 22 030 Within 7 - 15 working days

The second edition of "Tigers of the World" explores tiger biology, ecology, conservation, management, and the science and technology that make this possible. In 1988, when the first edition was published, tiger conservation was still in its infancy, and two decades later there has been a revolution not only in what is known, but how information about tigers is obtained and disseminated. In the fast changing world of conservation, there is a great need to summarize the vast and current state-of-the-art, to put this into historical perspective, and to speculate in what yet remains to be done. "Tigers of the World, 2e" fulfills this need by bringing together in a unique way the world s leading tiger experts into one volume. Despite the challenges ahead, there are bright spots in this story and lessons aplenty not only for tiger specialists but large carnivore specialists, conservation biologists, wildlife managers, natural resource policymakers, and most importantly the caring public.

*Examines the past twenty years of research from the world s leading tiger expertson biology, politics, and conservation.

*Describes latest methods used to disseminate and obtaininformation needed for conservation and care of this species.

*Includes coverage on genetics and ecology, policy, poaching and trade, captive breeding and farming, and the status of Asia s last wild tigers.

*Excellent resource for grad courses in conservation biology, wildlife management, and veterinary programs.

*New volume continues the classic Noyes Series in Animal Behavior, Ecology, Conservation and Management. "

R2,331 Discovery Miles 23 310 Within 7 - 15 working days

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).

Marine Mammals and Noise (Paperback, New edition): W. John Richardson, Charles R. Greene Jr., Charles I. Malme, Denis H. Thomson Marine Mammals and Noise (Paperback, New edition)
W. John Richardson, Charles R. Greene Jr., Charles I. Malme, Denis H. Thomson
R1,814 Discovery Miles 18 140 Within 7 - 15 working days

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.

Amniote Origins - Completing the Transition to Land (Hardcover): Stuart Sumida, Karen L.M. Martin Amniote Origins - Completing the Transition to Land (Hardcover)
Stuart Sumida, Karen L.M. Martin
R3,876 Discovery Miles 38 760 Within 7 - 15 working days

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.

Pathogen Indexing Technologies - Pathogen Indexing Technologies (Hardcover): J.A. Callow Pathogen Indexing Technologies - Pathogen Indexing Technologies (Hardcover)
J.A. Callow; Volume editing by S.H. De Boer, John H. Andrews, Inez C. Tommerup
R3,917 Discovery Miles 39 170 Within 7 - 15 working days

Significant advancements have been made in pathogen detection technologies during the last decade. Indexing of plants and plant parts for the presence of specific pathogens has been most effective in some instances for avoiding and/or controlling disease. The new technologies for detecting low levels of pathogens will increase the value of indexing as a tool for plant disease control. Providing an overview of the status of detection technology, this volume is directed not only to scientists and students interested in detection technology, but also to those interested in formulating and implementing disease control and quarantine regulations. This book provides a conceptual framework which presents the current scientific literature, state-of-the-art assessments, and speculations on future developments and requirements of pathogen indexing methods. Chapters cover the different pathogen groups, review current practices in areas where detection technology has become important, and provide perspectives on how indexing technologies can be applied, how well it has worked, and which problems remain. Statistical treatment of detection limits, sampling strategies, risk assessment, cost, standardization, and quality control are also covered.

Interpreting the Hierarchy of Nature - From Systematic Patterns to Evolutionary Process Theories (Hardcover): Lance Grande,... Interpreting the Hierarchy of Nature - From Systematic Patterns to Evolutionary Process Theories (Hardcover)
Lance Grande, Olivier Rieppel
R3,263 Discovery Miles 32 630 Within 7 - 15 working days

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

Plant Physiology (Hardcover): J. Sebanek Plant Physiology (Hardcover)
J. Sebanek
R7,569 Discovery Miles 75 690 Within 7 - 15 working days

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.
