Birds of Cyprus (Paperback): Colin Richardson, Richard Porter Birds of Cyprus (Paperback)
Colin Richardson, Richard Porter
R782 Discovery Miles 7 820 Ships in 10 - 15 working days

An authoritative guide to the birds of Cyprus Cyprus is a great place for birding, and one of the most popular places for birders to visit in Europe. It holds populations of a number of regional scarcities that are very hard to see elsewhere, plus a number of endemic subspecies, and the jewels in the crown - three full endemics, Cyprus Wheatear, Cyprus Scops Owl and Cyprus Warbler, the latter of which graces the jacket of this new Helm field guide to the island. Detailed plates are allied to concise identification text, with accurate maps stemming from Colin Richardson's decades-long programme of population-mapping on the island. Together, these elements make this the definitive guide to Cyprus's birds, one that no visitor to this beautiful island can be without.

Erik I Johnson, Jared D Wolfe
R1,569 Discovery Miles 15 690 Ships in 10 - 15 working days

Molt is an important avian life history event in which feathers are shed and replaced. The timing, duration, seasonality, extent and pattern of molt follows certain strategies and this book reviews and describes these strategies for nearly 190 species based on information gathered from a 30-year study of Central Amazonian birds. Most species accounts are illustrated with several color photos focusing on wing and tail feather molt, molt limits, and how to use these patterns to accurately age birds. Published in collaboration with and on behalf of the American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series is a rich source of life history information for ornithologists working on tropical birds.

In addition, a considerable part of the book is devoted to management implications and highlights aspects of human dimensions in recreational fisheries.

Fish Behaviour (Hardcover): Carin Magnhagen, Victoria A. Braithwaite, Elisabet Forsgren, B.G. Kapoor Fish Behaviour (Hardcover)
Carin Magnhagen, Victoria A. Braithwaite, Elisabet Forsgren, B.G. Kapoor
R5,826 Discovery Miles 58 260 Ships in 10 - 15 working days

Fishes are by far the most species-rich vertebrate taxon, and it is also the vertebrate group with the most strikingly diverse repertoire of behaviours and behavioural adaptations. As such, they provide us with many opportunities to explore the fascinating complexities of animal behaviour. Central questions addressed in this book include: How do sensory input, hormones, genetics and experience interact to shape individual behaviour? What should a fish do to be in the right place at the right time and how should it behave to be an efficient predator yet not become the subject of predation itself? How to find a mate or to find the best mate? Should all fish do the same, or is the optimal behaviour dependent on individual characteristics? How does reproductive behaviour affect what fish look like, in terms of colour, body form or body size? And how do fish cope with their complex social and biological environment, including parasites, competitors and collaborators? This new book provides an exciting overview of the many new insights offered by recent research on fish behaviour. The chapters are written by prominent international scientists and are aimed not only at fish biology students and researchers but anyone interested in the interplay between behaviour, ecology and evolution.

R1,566 Discovery Miles 15 660 Ships in 10 - 15 working days

Anguillid eels have fascinated biologists for centuries due to their spectacular long-distance migrations between freshwater habitats and their spawning areas far out in the ocean. This book provides a long overdue update on the biology and ecology of anguillid eels and features comprehensive coverage of the key features of the genus Anguilla. It covers a broad spectrum of topics on the biology (taxonomy, phylogeny, evolution, reproduction, feeding, salinity adaptation) and ecology (life history, recruitment, migration) of anguillid eels. It also brings together important information on the state of eel fisheries, conservation, exploitation, and management.

Biology of Turtles - From Structures to Strategies of Life (Hardcover): Jeanette Wyneken, Matthew H. Godfrey, Vincent Bels Biology of Turtles - From Structures to Strategies of Life (Hardcover)
Jeanette Wyneken, Matthew H. Godfrey, Vincent Bels
R4,809 Discovery Miles 48 090 Ships in 10 - 15 working days

Featuring in-depth contributions from an international team of experts, the Biology of Turtles provides the first comprehensive review of the Testudinata. The book starts with the premise that the structure of turtles is particularly interesting and best understood within the context of their development, novelty, functional diversity, and evolution. It provides a robust discussion of the development and diversity of the shell. The book also explores the turtle body plan, its physiological and ecological consequences, evolutionary novelties, and their importance. The 200 illustrations found throughout the text enhance the chapters combine with color illustrations of the development of the shell, aspects of bone structural diversity, growth, and skeletochronology, to make this book an unparalleled resource. The volume concludes with a thoughtful discussion of the more than century long debate on the origins of turtles and the reasons why our understanding of the phylogenic origins and evolution of turtles remains tentative. Currently available books on this subject are woefully out of date and no overall review of Testudinata has been undertaken...until now. Each chapter represents a milestone in synthesizing a wide range of available information on specific subjects. The book's challenge: look both inside and outside the shell to build a clearer understanding of the diversity and evolution of turtles.

Fish Larval Physiology (Hardcover): Roderick Nigel Finn Fish Larval Physiology (Hardcover)
Roderick Nigel Finn
R5,836 Discovery Miles 58 360 Ships in 10 - 15 working days

To study physiology is to examine how organisms have evolved solutions to the business of living in an inanimate world. Our world is and has always been dominated by physical and chemical forces. A physicist might tell us that all things are physical, while a chemist is more concerned with the elementary nature of reactions. A physical chemist sees the bonds between these views, and a biochemist draws out the organic symphony of the vital pathways. A structural biologist adds shape to the chemical building blocks of life, while a molecular biologist tinkers with these structures.This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the single-celled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution.This book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

Golden-winged Warbler Ecology, Conservation, and Habitat Management (Paperback): Henry M. Streby, David E. Andersen, David ... Golden-winged Warbler Ecology, Conservation, and Habitat Management (Paperback)
Henry M. Streby, David E. Andersen, David Buehler
R1,554 Discovery Miles 15 540 Ships in 10 - 15 working days

Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.

World-renowned primatologist, conservationist, and humanitarian Dr. Jane Goodall's account of her life among the wild chimpanzees of Gombe is one of the most enthralling stories of animal behavior ever written. Dr. Goodall's adventure began when the famous anthropologist Dr. Louis Leakey suggested that a long-term study of chimpanzees in the wild might shed light on the behavior of our closest living relatives. Accompanied by only her mother and her African assistants, she set up camp in the remote Gombe Stream Chimpanzee Reserve in Tanzania. For months the project seemed hopeless; out in the forest from dawn until dark, she had but fleeting glimpses of frightened animals. But gradually she won their trust and was able to record previously unknown behavior, such as the use--and even the making--of tools, until then believed to be an exclusive skill of man. As she came to know the chimps as individuals, she began to understand their complicated social hierarchy and observed many extraordinary behaviors, which have forever changed our understanding of the profound connection between humans and chimpanzees. In the Shadow of Man is "one of the Western world's great scientific achievements" (Stephen Jay Gould) and a vivid, essential journey of discovery for each new generation of readers.

A Natural History of the Brown Mouse Lemur (Paperback): Sylvia Atsalis A Natural History of the Brown Mouse Lemur (Paperback)
Sylvia Atsalis
R1,475 Discovery Miles 14 750 Ships in 10 - 15 working days

Part of the Prentice Hall's Primate Filed Studies series. This text can be used for any undergraduate or graduate course with a primate behavior or primate ecology component. It can also be used as supplemental reading, for any advanced animal behavior class. There are very few books that address the biology of nocturnal primates. There are even fewer that delve with any detail regarding the behavior of specific species. These animals are difficult to follow. Their diminutive size, the thickness of the vegetation, and their nocturnal habits, make the study of their habits a demanding task.Through a trial of patience, Sylvia Atsalis has undertaken this task. Here she provides an in depth view at the life and behavioral patterns of these tiny primates. A Natural History of the Brown Mouse Lemur provides the most complete look at the behavior and ecology of mouse lemurs.

The Functional and Evolutionary Biology of Primates (Paperback): Russell Tuttle The Functional and Evolutionary Biology of Primates (Paperback)
Russell Tuttle
R1,649 Discovery Miles 16 490 Ships in 10 - 15 working days

These original contributions on the evolution of primates and the techniques for studying the subject cover an enormous range of material and incorporate the work of specialists from many different fields, showing the necessity of a multidisciplinary approach to problems of primate morphology and phylogeny. Collectively, they demonstrate the concerns and methods of leading contemporary workers in this and related fields. Each contributor shows his way of attacking fundamental problems of evolutionary primatology.The range of findings in this book include new clues to the evolution of the middle ear and the subsistence behavior of early primates, a persuasive critique of the Smith-Jones hypothesis that many features of primate cranial morphology are adaptations to the special vicissitudes of arboreal habitation, the remarkable association of relative muscle mass in the hands and feet of catarrhine primates with the particularities of prehensile behaviors, the wealth of behavioral data that may be obtained by the concentrated study of certain primates in the vicinity of waterholes, the striking differences between inferences about the same behavioral phenomena that are based on long-term as opposed to short-term observations of one primate social group, and the strategy of sophisticated mathematical techniques for elucidating biomechanical, evolutionary, and behavioral problems.Each chapter conveys the status and progress of research in these and other particular areas of special interest, pointing the way toward further clarification of the functional biology and phylogeny of primates through the application of relatively new techniques or the comprehensive employment of available methods. No attempt is made to smooth over controversial points of view, or to endorse a single uniform model of primate evolution. This work will be an important reference for evolutionary and physical anthropologists, evolutionary biologists, comparative morphologists, human anatomists, behavioralists, and students of evolution.

Pleistocene Mammals of Europe (Paperback, New edition): Bj orn Kurt en Pleistocene Mammals of Europe (Paperback, New edition)
Bj orn Kurt en
R1,507 Discovery Miles 15 070 Ships in 10 - 15 working days

This book provides a comprehensive treatment of all the Pleistocene species in Europe, classified according to modern taxonomic principles. For each species there is a description of its descent and migration history, its range, and its mode of life.

The first version of this book was a semi popular paperback in the Swedish Aldus series. The present edition is completely rewritten and greatly expanded, but retains the non-technical approach to make the story accessible to readers with varying backgrounds. The first part of the book is an outline of the Pleistocene history of Europe, with its climatic changes and succession of mammalian faunas. In the second part are listed all the species of Mammalia known from the Pleistocene and Postglacial of Europe, with the evolution, range in time and space, and mode of life set down for each species, as far as known. The final part is an evaluation of the story in terms of evolution and palaeogeography.

The author begins with a description of the floral and faunal succession in Europe, from the Villafranchian period, when climatic changes were moderate, to the increasing temperature oscillations of the later Pleistocene, with its recurrent faunal revolutions. Against this background Kurten then deals with the whole range of the mammalian species, and his account is fully illustrated by reconstructions and text figures showing skeletal and odontological characters. The book concludes with an analysis of the material available for this study, which throws fresh light on several aspects of zoogeography, evolution, and ecology.

This is the most complete account of the mammalian species of Europe yet to appear, and will be of great value to all paleontologists.

"Bjrn Kurtun" (1924-1988) was lecturer in palaeontology at the University of Helsinki. He is well known for his studies of the Pleistocene carnivores and of human evolution. He was a recipient of Unesco's Kalinga Award. Some of his most famous publications include "On the Variation and Population Dynamics of Fossil and Recent Mammal Populations" and "Pleistocene Mammals of North America."

The Birds are our Friends (Paperback): Yessengali Raushanov The Birds are our Friends (Paperback)
Yessengali Raushanov
R553 Discovery Miles 5 530 Ships in 9 - 17 working days

For many, birds represent freedom and spirituality since they are created to be free. Although this may be true for people as well, we are of course not able to be as truly free as our winged friends. Looking out of his office window and seeing the birds flying, emphasising his confinement indoors and the unnecessary complexities of life in general, the author regrets his lost freedom. Life tends to be over-complicated and many would advocate following a simpler life. Birds, on the other hand, live the life they are destined for and this book shows how a common love of birds bridges cultures and distance. The Birds are our Friends is a wonderful and enlightening collection of essential information, curiosities, myths and folklore of birds and people. The author has discovered the role that birds play in people's imagination, and their significance for various cultures. People's accounts of birds give an insight to themselves - what they strive for, what they are afraid of and what they find important. Some birds predict the weather and construct unbelievably sophisticated nests or engage in elegant mating rituals. The author provides new insights on these facts and myths which confound some widely-held assumptions of their activities. Yessengali has a deeply personal connection and relationship with some birds. His fondest memories from childhood or young adulthood are associated with cuckoos, storks, and other birds that remind him of love and friendship. He hopes that these stories will interest readers, remind them of their spirituality and also evoke fine memories. In any event, it is a book that illuminates the world of birds from a slightly different viewpoint.

Fish Chemoreception (Hardcover, 1992 ed.): T.J. Hara Fish Chemoreception (Hardcover, 1992 ed.)
T.J. Hara
R7,841 Discovery Miles 78 410 Ships in 18 - 22 working days

This book describes in general how the chemosensory systems of fish function at various levels. In many ways, fish are typical vertebrates differing only slightly from other vertebrates including humans. In other ways, their aquatic environment imposes strict requirements or offers unique opportunities which have resulted in some unusual functions having no counterpart in higher vertebrates. This new volume is necessitated by advances in many vital areas as the field of chemical senses continues to grow at a rapid pace. Most significant is the application of the contemporary electrophysiological technique of patch-clamping, recognition of a second messenger system in chemosensory transduction processes and the identification of hormonal pheromones in fish reproductive behaviour. The last major synthesis of our knowledge about fish chemoreception, Chemoreception in Fishes, was published ten years ago (Elsevier, Amsterdam, 1982). In that volume four aspects of fish chemoreception, Le. morphology of the peripheral chemoreceptors. primary sensory processes, roles in behaviour, and its interactions with environment, were discussed. This book is intended to be helpful to students, scientists and aquacul turists not only as a source book but also as a textbook on chemical senses."

Snow Leopards: Biodiversity of the World: Conservation from Genes to Landscapes is the only comprehensive work on the biology, behavior, and conservation status of the snow leopard, a species that has long been one of the least studied, and hence poorly understood, of the large cats. Breakthroughs in technologies and methodologies to study this elusive cat have come rapidly, including non-invasive genetics, camera traps, and GPS-satellite collaring. The book begins with chapters on the genetic standing and taxonomy of the snow leopard, followed by chapters on their behavior and ecology. Additional contributions follow on the current and emerging threats to the species, which include longstanding concerns, such as poaching and conflicts with livestock, and new and emerging threats such as mining and climate change. A section on conservation solutions, backed by valuable case studies, starts with an overview of the important role mountain communities play in assuring the snow leopard's long-term persistence. In addition, chapters on the role of captive snow leopards for the conservation of the species, state-of-the-art techniques and technologies for studying and monitoring snow leopards, status reports from around the region, and future perspectives, such as transboundary conservation initiatives, international conventions (CITES, CMS, etc.), the role of the IUCN Cat Specialist Group and the Snow Leopard Network, and undertakings such as the Global Snow Leopard Forum facilitated by the World Bank are also included.

Sex and Friendship in Baboons (Paperback): Barbara B. Smuts Sex and Friendship in Baboons (Paperback)
Barbara B. Smuts
R1,525 Discovery Miles 15 250 Ships in 10 - 15 working days

Those who have been privileged to watch baboons long enough to know them as individuals and who have learned to interpret some of their more subtle interactions will attest that the rapid flow of baboon behavior can at times be overwhelming. In fact, some of the most sophisticated and influential observation methods for sampling vertebrate social behavior grew out of baboon studies, invented by scientists who were trying to cope with the intricacies of baboon behavior. Barbara Smuts' eloquent study of baboons reveals a new depth to their behavior and extends the theories needed to account for it.

While adhering to the most scrupulous methodological strictures, the author maintains an open research strategy--respecting her subjects by approaching them with the open mind of an ethnographer and immersing herself in the complexities of baboon social life before formulating her research design, allowing her to detect and document a new level of subtlety in their behavior. At the Gilgil site, described in this book, she could stroll and sit within a few feet of her subjects. By maintaining such proximity she was able to watch and listen to intimate exchanges within the troop; she was able, in other words, to shift the baboons well along the continuum from "subject" to "informant." By doing so she has illuminated new networks of special relationships in baboons. This empirical contribution accompanies theoretical insights that not only help to explain many of the inconsistencies of previous studies but also provide the foundation for a whole new dimension in the study of primate behavior: analysis oft he dynamics of long-term, intimate relationships and their evolutionary significance.

At every stage of research human observers have underestimated the baboon. These intelligent, curious, emotional, and long-lived creatures are capable of employing stratagems and forming relationships that are not easily detected by traditional research methods. In the process of unraveling their complex social relationships, Smuts has revealed that these masters of strategy and aggressive competition are equally capable of patience, tenderness, and concern.

"Barbara B. Smuts" is professor of psychology and anthropology, University of Michigan, Ann Arbor. She is also the author of Primate Societies.

Primate Societies - Group Techniques of Ecological Adaptation (Paperback): Hans Kummer Primate Societies - Group Techniques of Ecological Adaptation (Paperback)
Hans Kummer
R1,510 Discovery Miles 15 100 Ships in 10 - 15 working days

In this book, Hans Kummer, one of the world's leading primate ethologists, examines the patterns of social interaction among primates. He examines this social behavior from the fundamentally biological viewpoint of evolutionary adaptation as part of the survival mechanisms for the species. Recognizing that all activity is constituted in part of genetic programming and in part of adaptive behavior, he explores the borderline area between the genetic and the "cultural." By use of astute observation and clever experimentation he shows that many aspects of social behavior are inherited, and differentially inherited among various primate groups. These data also show, however, that the individuals and troops learn much in primate social life and that these forms are responsive to particular ecological situations. Drawing heavily on knowledge gleaned from his own well-known studies of the Hamadryas baboon, Dr. Kummer introduces the reader to the daily life of a particular primate society. From this sample case, he proceeds to a more general characterization of primate societies, using as examples the great apes and monkeys of Africa, Asia, and South America and particularly the widely studied terrestrial monkey species. The particularities of primate communication, social structure, and economy are described and special attention is devoted to the primate counterparts of kinship and age groups-behavioral differences based on age and sex, and mating and grouping systems. This is followed by a chapter dealing with the ecological functions of the major parameters of primate social life, such as group size and the coordination of activities within it-dominance, leadership systems, and spatial arrangements. The second part of the book is concerned with the origins of behavioral traits of primates, discussed from phylogenetic, ecological, and cultural points of view, again using data-based examples. Dr. Kummer explains why some traits have not evolved that would have been adaptive, and traces the rise of several secondary functions in their place. The final section of- the book confronts man with his fellow primates, emphasizing the probable limits imposed upon human culture by the existing phylogenetic heritage. Hans Kummer earned his Ph.D. in zoology from the University of Zurich. His research projects include study of the spatial and fami1y organization of primate groups at the Delta Regional Primate Research Center at Covington, La., and three years of field study of the social behavior of baboons in Ethiopia. Dr. Kummer has contributed articles to many journals and symposia. Since 1969, he has been Assistant Professor of Zoology at the University of Zurich.

Seals are the sleekest and most agile of all marine mammals, and they are superbly adapted to the watery world in which they spend most of their time. With their whiskery dog-like faces, curious nature and vulnerable pups, they are enduringly appealing animals. Although air-breathing, seals are superbly tuned to hunt, sleep, mate and keep warm while out at sea, but they remain inextricably linked to land. In Spotlight Seals, Frances Dipper explores the intricate lives of the UK's native Grey and Common Seals and their amazing physical and behavioural adaptations to a life split between land and sea. She reveals the complex physiology that allows seals to dive deep and for long periods without coming to any harm. Once exploited for their meat and skins, seals now have protection around the British Isles. Their numbers are increasing, but they still face the danger of plastic litter in their environment. Dipper also explores age-old legends, interactions between humans and seals, and the best places to watch them in the UK. The Spotlight series introduces readers to the lives and behaviour of our favourite animals with eye-catching colour photographs and informative expert text.
