The ultimate reference book for bird enthusiasts - now in its third edition. With expanded text and additional colour illustrations, the third edition of the hugely successful Collins Bird Guide is a must for every birdwatcher. The new edition has an extra 32 pages allowing several groups more space and completely or partly new plates with more detailed text: grouse, loons, several groups of raptors, terns, owls, swifts, woodpeckers, swallows, redstarts and some other relatives to the flycatchers (formerly often called 'small thrushes'), tits and a few finches and buntings are some of these. More than 50 plates are either new or have been repainted, completely or partly. Apart from this, a few new vignettes have been added. The section with vagrants has been expanded to accommodate more images and longer texts for several species. The entire text and all maps have of course also been revised. The book provides all the information needed to identify any species at any time of the year, covering size, habitat, range, identification and voice. Accompanying every species entry is a distribution map and illustrations showing the species in all the major plumages (male, female, immature, in flight, at rest, feeding: whatever is important). In addition, each group of birds includes an introduction which covers the major problems involved in identifying or observing them: how to organise a sea watching trip, how to separate birds of prey in flight, which duck hybrids can be confused with which main species. These and many other common birdwatching questions are answered. The combination of definitive text, up-to-date distribution maps and superb illustrations, all in a single volume, makes this book the ultimate field guide, essential on every bookshelf and birdwatching trip.

Wild Air (Hardcover): James Macdonald Lockhart Wild Air (Hardcover)
James Macdonald Lockhart
R386 Discovery Miles 3 860 Ships in 12 - 19 working days

A book about birdsong, from the critically acclaimed author of Raptor. In Wild Air, James Macdonald Lockhart sets out to write about a series of birds as though he has his granny's role of listening to birds' songs and calls and relaying what she heard to her aged and by then quite deaf father - the famous naturalist Seton Gordon. From a nightjar's strange churring song on a heath in the south of England, to a lapwing displaying over the machair in the Outer Hebrides, he writes about eight different birds who he has spent most time with, returned to most often and relays what he hears. The eight species are all representative of a different habitat. Nightjars on a lowland heath; shearwaters on a mountain overlooking the sea; dippers on a river; skylarks in farmland; ravens in woodland; divers on a loch; lapwings on the coast; and nightingales in dense scrub. Not all of the birds are songbirds in the traditional sense, though each possesses its own distinctive music. That music can vary from the strange, as in the weird gurgling sound a shearwater makes inside its burrow, to the joyous exuberance of the skylark's song. Sometimes, he hears a lot, and sees little (shearwaters in the pitch dark); sometimes he sees a lot, but hears little (black-throated divers on their loch). But in every case the sounds the birds make become an introduction to their lives - an audible introduction to the birds and the places they are found.

Dramatic changes in the environment, including habitat degradation and climate change, have focused attention on how individuals and populations respond to a shifting biotic and abiotic landscape. A critical step toward meeting this goal is a clear understanding of the capacity of individuals to defend themselves against threats. Changes in water quality and temperature have direct and indirect effects on fishes. Defensive responses can occur at many levels, from cellular to behavioral actions. The authors in this volume have attempted to provide a general view of the current state of knowledge of fish defenses with respect to pathogens, parasites, and predators, and to point out gaps where further study is needed.

Fish Defenses Vol. 1 - Immunology (Hardcover): Giacomo Zaccone Fish Defenses Vol. 1 - Immunology (Hardcover)
Giacomo Zaccone
R6,303 Discovery Miles 63 030 Ships in 12 - 19 working days

The greatest complexity of the immune response is shown by vertebrates which are endowed with innate and acquired immunity. Immunological studies performed mostly in mammals have been the reference for studies in other vertebrates. The study of immunological fish defenses has advanced considerably in recent decades. This has been due to the key status of fish in terms of the evolution of acquired immunity and due to the rapid expansion of aquaculture over this period, wherein disease control is of prime concern. Most of the chapters not only review the current advances on fish immune defenses, but also show perspective for future research. The book will be of interest to scientists involved in fish immunology, fisheries and aquaculture as well as for students of fish biology.

Thad Q. Bartlett
R1,464 Discovery Miles 14 640 Ships in 12 - 19 working days

Primatologists have long viewed small fruiting trees, like figs, as the reason for gibbons' territorial and monogamous behavior. However, at Khao Yai National Park in Thailand where gibbons are prevalent, figs are one of the largest trees in the forest. In this long-term field study, Bartlett addresses this apparent contradiction and follows gibbons as their major food sources fluctuate over time. The titles in the Primate Field Studies series impart the comprehensive results of long-term field studies to a broad audience at a critical time. Long-term field studies often have a cohesive story to tell which encompasses many different topics, from group size and food distribution, to social behavior, reproduction, and demography. The comprehensive and accessible monographs can supplement textbooks, or may be used as a stand-alone text in upper-level primatology courses.

Amphibian Survey and Monitoring Handbook (Paperback): John W. Wilkinson Amphibian Survey and Monitoring Handbook (Paperback)

R1,080 Discovery Miles 10 800 Ships in 12 - 19 working days

"Evidence bases for conservation are becoming increasingly important to convince landowners and politicians of the need to take action in defence of species and habitats all around the world. A valuable feature of this book is its emphasis on collecting and analysing such essential information." Trevor Beebee, Phyllomedusa Amphibians are among the most globally endangered groups of vertebrates with more than one-third of species being assessed as declining or threatened. Often, amphibian declines can be attributed to a suite of interacting factors, many of which are human in origin, but further information is needed to elaborate the key causes and to discover ways of reversing declines. Robust surveys provide vital ecological and biological data on amphibian populations, and underpin the decisions made to protect species and reverse their declines. Ongoing monitoring informs land managers and decision makers about whether they are taking the right action. This book is designed to help you carry out amphibian surveying and monitoring so that the results of your surveys can be used effectively. Part 1 introduces amphibians: order Anura (frogs and toads); Caudata (newts and salamanders); and order Gymnophonia (caecilians). Part 2 is essential reading before you start surveying. It introduces the different types of survey and monitoring programmes and discusses survey aims and resources. It contains chapters on collecting and handling survey data; survey permissions and licencing; health and safety, and biosecurity; and handling amphibians. Part 3 discusses everything you need to know during your survey, and provides a detailed look at amphibian survey methods. Part 4 covers presenting and using your survey's data to best effect. A useful resources section is also provided, with example survey forms and details of additional information resources that will optimize the impacts of your surveys. Key amphibian survey techniques are discussed with reference to published examples of successful surveys - so you'll be able to choose what's right for your situation. Tips on optimizing your survey effort and handling amphibians in the field are also included. Whether carrying out a student expedition project or seeking information to support the management of a protected area, this book contains essential advice from an amphibian ecologist who has encountered the same sorts of decisions you'll face when planning your surveys.

This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program.
The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats.


* An up to date work by the world's leading expert on bird flight
* Examines the biology and biomechanics of bird flight with added reference to the flight of bats and pterosaurs.
* Uses proven aeronautical principles to help solve biological issues in understanding and predicting the flight capabilities of birds and other vertebrates.
* Provides insights into the evolution of flight and the likely capabilities of extinct birds and reptiles.
* Gives a detailed explanation of the science behind, and use of, the author's predictive bird flight simulation program - Flight - which is available on a companion website.

R5,697 Discovery Miles 56 970 Ships in 12 - 19 working days

Using R for Modelling and Quantitative Methods in Fisheries has evolved and been adapted from an earlier book by the same author and provides a detailed introduction to analytical methods commonly used by fishery scientists, ecologists, and advanced students using the open-source software R as a programming tool. Some knowledge of R is assumed, as this is a book about using R, but an introduction to the development and working of functions, and how one can explore the contents of R functions and packages, is provided. The example analyses proceed step-by-step using code listed in the book and from the book's companion R package, MQMF, available from GitHub and the standard archive, CRAN. The examples are designed to be simple to modify so the reader can quickly adapt the methods described to use with their own data. A primary aim of the book is to be a useful resource to natural resource practitioners and students. Featured Chapters: Model Parameter Estimation provides a detailed explanation of the requirements and steps involved in fitting models to data, using R and, mainly, maximum likelihood methods. On Uncertainty uses R to implement bootstrapping, likelihood profiles, asymptotic errors, and Bayesian posteriors to characterize any uncertainty in an analysis. The use of the Monte Carlo Markov Chain methodology is examined in some detail. Surplus Production Models applies all the methods examined in the earlier parts of the book to conducting a stock assessment. This included fitting alternative models to the available data, characterizing the uncertainty in different ways, and projecting the optimum models forward in time as the basis for providing useful management advice.

Fish Larval Physiology (Hardcover): Roderick Nigel Finn Fish Larval Physiology (Hardcover)
Roderick Nigel Finn
R5,903 Discovery Miles 59 030 Ships in 12 - 19 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.

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.

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.

Pleistocene Mammals of Europe (Paperback, New edition): Bj orn Kurt en Pleistocene Mammals of Europe (Paperback, New edition)
Bj orn Kurt en
R1,508 Discovery Miles 15 080 Ships in 12 - 19 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."

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.

Manatees, the gentle giants of Florida's lagoons and coastal habitats, can bring a smile to the face of anybody lucky enough to spy one. As manatees dip and roll through the water, crowds gather to watch them feed on aquatic vegetation. Whether they are congregating by the hundreds or resting or feeding alone, viewing these sea cows can provide anyone interested in nature with hours of tranquil pleasure. Having survived for eons, today's manatees are now under constant threat due to our rapidly swelling human population. Their habitats are often devastated by development and pollution. The slow-moving manatees also live at the mercy of chance, for they occupy waters filled with fast-moving boats powered by razor-sharp propellers-a new form of predator from which they have no protection. Boat speed limits have been put in place to protect manatees, but there is a constant push to lift them so that people can once again zip across the waters that manatees call home. For this reason, manatees are often a subject of controversy that pits their lives against the rights of boat owners. In this book, manatee expert John E. Reynolds III and famed photographer Wayne Lynch join forces to reveal the clearest portrait of manatees ever published. Florida Manatees is a song for the manatee, a celebration of the lives of these majestic creatures. Reynolds's concise, informative text shares what scientists know about manatees, while Lynch's beautiful photographs instantly demonstrate how special these "potatoes with whiskers" really are. By encouraging an appreciation of manatees, the authors hope to help ensure a future in which Floridians can find ways to coexist with and continue to enjoy these uniquely wonderful sirenian inhabitants of their state. Included in this book:* How manatees first came to Florida waters* How manatees fit into the ecosystems of Florida* What and how much manatees eat* How manatees behave and communicate with one another* Why manatees look the way they do* Why manatees have whiskers* How manatee mothers feed their young and much more

Sex and Friendship in Baboons (Paperback): Barbara B. Smuts Sex and Friendship in Baboons (Paperback)
Barbara B. Smuts
R1,527 Discovery Miles 15 270 Ships in 12 - 19 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.

Primate Societies - Group Techniques of Ecological Adaptation (Paperback): Hans Kummer Primate Societies - Group Techniques of Ecological Adaptation (Paperback)
Hans Kummer
R1,511 Discovery Miles 15 110 Ships in 12 - 19 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.
