Biology and Evolution of Crocodylians (Hardcover): Gordon C. Grigg, David Kirshner Biology and Evolution of Crocodylians (Hardcover)
Gordon C. Grigg, David Kirshner; Foreword by Rick Shine
R2,953 R2,392 Discovery Miles 23 920 Save R561 (19%) Shipped within 7 - 12 working days

Crocodiles, alligators, caimans, and gharials--the Crocodylia, known collectively as crocodylians (or crocodilians)--are the world's largest living reptiles. The largest of them, probably the estuarine or saltwater crocodile, Crocodylus porosus, can grow to almost twenty feet and weigh more than two thousand pounds. Crocodylians are creatures of great contrast. They can remain patiently still for ages, yet can also move like lightning to snap up a meal. They are formidably strong, active predators, with jaws that can tear apart large prey items, yet a mother or a father can gently assist hatchlings out of the eggs, and carry them to the water between their teeth. Because large crocodylians can (and do) eat people, they invite fear and loathing, but they also inspire curiosity and admiration. Biology and Evolution of Crocdylians is a comprehensive review of current knowledge about the world's largest and most famous living reptiles. Gordon Grigg's authoritative and accessible text and David Kirshner's stunning artwork and color photographs combine expertly in this contemporary celebration of crocodiles, alligators, caimans, and gharials. This book showcases the skills and capabilities that allow crocodylians to live how and where they do. It covers the biology and ecology of the extant species, conservation issues, crocodilian-human interaction, and the evolutionary history of the group. Richly illustrated with more than five hundred color photographs and black-and-white illustrations, this book will be a benchmark reference work for crocodylian biologists, herpetologists, and vertebrate biologists for years to come.

Many animals, including humans, acquire valuable skills and knowledge by copying others. Scientists refer to this as social learning. It is one of the most exciting and rapidly developing areas of behavioral research and sits at the interface of many academic disciplines, including biology, experimental psychology, economics, and cognitive neuroscience. "Social Learning" provides a comprehensive, practical guide to the research methods of this important emerging field."" William Hoppitt and Kevin Laland define the mechanisms thought to underlie social learning and demonstrate how to distinguish them experimentally in the laboratory. They present techniques for detecting and quantifying social learning in nature, including statistical modeling of the spatial distribution of behavior traits. They also describe the latest theory and empirical findings on social learning strategies, and introduce readers to mathematical methods and models used in the study of cultural evolution. This book is an indispensable tool for researchers and an essential primer for students.Provides a comprehensive, practical guide to social learning research Combines theoretical and empirical approaches Describes techniques for the laboratory and the field Covers social learning mechanisms and strategies, statistical modeling techniques for field data, mathematical modeling of cultural evolution, and more

Animal Social Networks (Paperback): Jens Krause, Richard James, Daniel Franks, Darren P. Croft Animal Social Networks (Paperback)
Jens Krause, Richard James, Daniel Franks, Darren P. Croft
R990 Discovery Miles 9 900 Shipped within 7 - 12 working days

The scientific study of networks - computer, social, and biological - has received an enormous amount of interest in recent years. However, the network approach has been applied to the field of animal behaviour relatively late compared to many other biological disciplines. Understanding social network structure is of great importance for biologists since the structural characteristics of any network will affect its constituent members and influence a range of diverse behaviours. These include finding and choosing a sexual partner, developing and maintaining cooperative relationships, and engaging in foraging and anti-predator behavior. This novel text provides an overview of the insights that network analysis has provided into major biological processes, and how it has enhanced our understanding of the social organisation of several important taxonomic groups. It brings together researchers from a wide range of disciplines with the aim of providing both an overview of the power of the network approach for understanding patterns and process in animal populations, as well as outlining how current methodological constraints and challenges can be overcome. Animal Social Networks is principally aimed at graduate level students and researchers in the fields of ecology, zoology, animal behaviour, and evolutionary biology but will also be of interest to social scientists.

'Peter Wohlleben doesn't merely look, he sees. Let's all learn as much from him as we can, and quickly.' Rosamund Young, author of THE SECRET LIFE OF COWS Did you know that trees can influence the rotation of the earth? Or that wolves can alter the course of a river? Or that earthworms control wild boar populations? The natural world is a web of intricate connections, many of which go unnoticed by humans. But it is these connections that maintain nature's finely balanced equilibrium. Drawing on the latest scientific discoveries and decades of experience as a forester and bestselling author, Peter Wohlleben shows us how different animals, plants, rivers, rocks and weather systems cooperate, and what's at stake when these delicate systems are unbalanced. The earth's ecosystems are too complex for us to compartmentalise and draw up simple rules of cause and effect; but The Secret Network of Nature gives us a chance to marvel at the inner workings and unlikely partnerships of the natural world, where every entity has its own distinct purpose. And the more light that is shed on relationships between species, the more fascinating nature's web becomes.

Dragonflies - Behavior and Ecology of Odonata (Hardcover): Philip S. Corbet Dragonflies - Behavior and Ecology of Odonata (Hardcover)
Philip S. Corbet
R3,334 Discovery Miles 33 340 Shipped within 7 - 11 working days

Among the most ancient and powerful of insects, dragonflies fascinate scientists and nonspecialists in part because they are large enough for the behavior of individual insects to be observed and interpreted. Indeed, so much useful information exists about dragonflies that they serve as valuable models for interpreting the behavior and ecology of other taxa. Philip S. Corbet has devoted a lifetime to their study. His book A Biology of Dragonflies has been a standard text for more than thirty-five years. This latest book establishes a new benchmark for the Odonata, providing a comprehensive, critical review of past and current knowledge both published and unpublished about species from all biogeographical regions in both functional and evolutionary contexts. The volume emphasizes the diversity found in dragonfly behavior as well as unifying patterns. It describes the behavioral strategies that influence the fitness of individuals in physical and biotic environments and in all stages of the life cycle, and identifies the biological principles reflected in those strategies. The book also examines behavior associated with processes such as habitat selection, foraging, seasonal regulation, migration, territoriality, mating, and sperm competition, emphasizing the interdependence of all developmental stages as well as relationships among dragonflies and other animals, including humans. Dragonflies represents a remarkably thorough and searching appraisal of a single taxon, featuring 252 drawings and black-and-white photographs, 96 color plates, nearly 100 appendix tables, and more than 4,000 bibliographic citations to original sources. The wealth of information and its integrated treatment will indisputably make the book the definitive source on dragonflies for years to come."

In the last decade, research on the previously dormant field of camouflage has advanced rapidly, with numerous studies challenging traditional concepts, investigating previously untested theories and incorporating a greater appreciation of the visual and cognitive systems of the observer. Using studies of both real animals and artificial systems, this book synthesises the current state of play in camouflage research and understanding. It introduces the different types of camouflage and how they work, including background matching, disruptive coloration and obliterative shading. It also demonstrates the methodologies used to study them and discusses how camouflage relates to other subjects, particularly with regard to what it can tell us about visual perception. The mixture of primary research and reviews shows students and researchers where the field currently stands and where exciting and important problems remain to be solved, illustrating how the study of camouflage is likely to progress in the future.

CCTV for Wildlife Monitoring is a handbook on the use of CCTV in nature watching, conservation and ecological research. CCTV offers a unique ability to monitor wildlife in real time, stream video to the web, capture imagery of fast-moving species or cold animals such as wet otters or fish and maintain monitoring over long periods of time in a diverse array of habitats. Wildlife watchers can take advantage of a huge range of CCTV cameras, recording devices and accessories developed for use in non-wildlife applications. CCTV allows intimate study of animal behaviour not possible with other technologies. With expert experience in engineering, photography and wildlife, Susan Young describes CCTV equipment and techniques, giving readers the confidence to tackle what initially may seem technically challenging. The book enables the reader to navigate the technical aspects of recording: basic analogue, high definition HD-TVI and IP cameras, portable CCTV, digital video recorders (DVR) and video processing by focusing on practical applications. No prior knowledge of CCTV is required - step-by-step information is provided to get anyone started recording wildlife. In-depth methods for recording foxes, badger, deer, otters, small mammals and fish are also included, and the book makes comparisons with trail cameras where appropriate. Examples of recorded footage illustrate the book along with detailed diagrams on camera set-ups and links to accompanying videos on YouTube. Case-studies show real projects, both the equipment used and the results. This book will be of interest to amateur naturalists wishing to have a window into the private world of wildlife, ecological consultants monitoring protected species and research scientists studying animal behaviour.

Evolving Insight (Paperback): Richard W. Byrne Evolving Insight (Paperback)
Richard W. Byrne
R657 Discovery Miles 6 570 Shipped within 7 - 12 working days

'Insight' is not a very popular word in psychology or biology. Popular terms-like "intelligence", "planning", "complexity" or "cognitive"- have a habit of sprawling out to include everyone's favourite interpretation, and end up with such vague meanings that each new writer has to redefine them for use. Insight remains in everyday usage: as a down-to-earth, lay term for a deep, shrewd or discerning kind of understanding. Insight is a good thing to have, so it's important to find out how it evolved, and that's what this book is about. Coming 20 years after publication of Richard Byrne's seminal book The Thinking Ape, Evolving Insight develops a new theory of the evolutionary origins of human abilities to understand the world of objects and other people. Defining mental representation and computation as 'insight', it reviews the evidence for insight in the cognition of animals. The book proposes that the understanding of causality and intentionality evolved twice in human ancestry: the "pretty good" understanding given by behaviour parsing, shared with other apes and related to cerebellar expansion; and the deeper understanding which requires language to model and is unique to humans. However, Ape-type insight may underlie non-verbal tests of intentionality and causal understanding, and much everyday human action. Accessible to those with little background in the topic, Evolving Insight is an important new work for anyone with an interest in psychology and the biological sciences.

While observing a family of elephants in the wild, Caitlin O'Connell noticed a peculiar listening behavior--the matriarch lifted her foot and scanned the horizon, causing the other elephants to follow suit, as if they could "hear" the ground. "The Elephant's Secret Sense" is O'Connell's account of her groundbreaking research into seismic listening and communication, chronicling the extraordinary social lives of elephants over the course of fourteen years in the Namibian wilderness.
This compelling odyssey of scientific discovery is also a frank account of fieldwork in a poverty-stricken, war-ravaged country. In her attempts to study an elephant community, O'Connell encounters corrupt government bureaucrats, deadly lions and rhinos, poachers, farmers fighting for arable land, and profoundly ineffective approaches to wildlife conservation. "The Elephant's Secret Sense "is ultimately a story of intellectual courage in the face of seemingly insurmountable obstacles.

In the quiet halls of the natural history museum, there are some creatures still alive with stories, whose personalities refuse to be relegated to the dusty corners of an exhibit. The fame of these beasts during their lifetimes has given them an iconic status in death. More than just museum specimens, these animals have attained a second life as historical and cultural records. This collection of essays--from a broad array of contributors, including anthropologists, curators, fine artists, geographers, historians, and journalists--comprises short "biographies" of a number of famous taxidermized animals. Each essay traces the life, death, and museum "afterlife" of a specific creature, illuminating the overlooked role of the dead beast in the modern human-animal encounter through practices as disparate as hunting and zookeeping. The contributors offer fresh examinations of the many levels at which humans engage with other animals, especially those that function as both natural and cultural phenomena, including Queen Charlotte's pet zebra, Maharajah the elephant, and Balto the sled dog, among others. Readers curious about the enduring fascination with animals who have attained these strange afterlives will be drawn to the individual narratives within each essay, while learning more about the scientific, cultural, and museological contexts of each subject. Ranging from autobiographical to analytical, the contributors' varying styles make this delightful book a true menagerie.

"Pollination and Floral Ecology" is the most comprehensive single-volume reference to all aspects of pollination biology--and the first fully up-to-date resource of its kind to appear in decades. This beautifully illustrated book describes how flowers use colors, shapes, and scents to advertise themselves; how they offer pollen and nectar as rewards; and how they share complex interactions with beetles, birds, bats, bees, and other creatures. The ecology of these interactions is covered in depth, including the timing and patterning of flowering, competition among flowering plants to attract certain visitors and deter others, and the many ways plants and animals can cheat each other.

"Pollination and Floral Ecology" pays special attention to the prevalence of specialization and generalization in animal-flower interactions, and examines how a lack of distinction between casual visitors and true pollinators can produce misleading conclusions about flower evolution and animal-flower mutualism. This one-of-a-kind reference also gives insights into the vital pollination services that animals provide to crops and native flora, and sets these issues in the context of today's global pollination crisis. Provides the most up-to-date resource on pollination and floral ecology Describes flower advertising features and rewards, foraging and learning by flower-visiting animals, behaviors of generalist and specialist pollinators--and more Examines the ecology and evolution of animal-flower interactions, from the molecular to macroevolutionary scale Features hundreds of color and black-and-white illustrations

Correctly identifying young salmonids improves the accuracy of resource management information, leading to a fuller knowledge of the distribution and status of fish stocks. Until now, identifying coastal salmonids during their fry to smolt life stages in freshwater and saltwater estuaries of the Pacific Northwest has been difficult due to the lack of comprehensive, practical information. This guide was written and compiled by top fisheries biologists from government and industry who wanted to make available a simple, easy-to-use system for identifying 10 of the most common species of juvenile salmon, trout and char in the field.
The guide uses high-quality photos, colour illustrations and detailed drawings to show distinguishing physical features for each species. An easy-to-follow chart facilitates identification of the three major groupings and individual species. Habitat use information and maps help to determine where and when various species may be found for sampling.

From a modest beginning in the form of a little shrew-like, nocturnal, insect eating ancestor that lived 200 million years ago, mammals evolved into the huge variety of different kinds of animals we see today. Many species are still small, and follow the lifestyle of the ancestor, but others have adapted to become large grazers and browsers, like the antelopes, cattle, rhinos, and elephants, or the lions, hyaenas, and wolves that prey upon them. Yet others evolved to be specialist termite eaters able to dig into the hardest mounds, or tunnel creating burrowers, and a few took to the skies as gliders and the bats. Many live partly in the water, such as otters, beavers, and hippos, while whales and dugongs remain permanently in the seas, incapable of ever emerging onto land. In this Very Short Introduction T. S. Kemp explains how it is a tenfold increase in metabolic rate - endothermy or "warm-bloodedness" - that lies behind the high levels of activity, and the relatively huge brain associated with complex, adaptable behaviour that epitomizes mammals. He describes the remarkable fossil record, revealing how and when the mammals gained their characteristics, and the tortuous course of their subsequent evolution, during which many bizarre forms such as sabre-toothed cats, and 30-tonne, 6-m high browsers arose and disappeared. Describing the wonderful adaptations that mammals evolved to suit their varied modes of life, he also looks at those of the mainly arboreal primates that culminated ultimately in Homo sapiens.

This book comprehensively describes the transgenesis techniques and applied experimental methods in ascidians including enthusiastically developed original devices in addition to concrete examples of developmental biology studies. Ascidians have been one of the most important model animals in developmental biology for studying molecular and cellular processes underlying formation of the chordate body plan. Transgenic techniques such as microinjection, electropolation, cis-element analysis and application, and TALENs and CRISPR/Cas9 have been developed in ascidians for more than 20 years, and now many applied methods, some of which are unique in ascidians, have been accumulated. Those extensive technological innovations, such as cell isolation, cell labeling, germ-line transformation, marker transgenic lines, and the experimental systems for studying notochord formation and nervous system, are exceptional particularly in marine invertebrates. This book is useful for ascidian researchers to quickly access the techniques in which they are interested as well as to compare each technology to become familiar with specialized tips, and for biologists of other organisms to learn the unique techniques and ingenious attempts specific to ascidians. Providing detailed and easily understandable descriptions of techniques, the book will inspire ascidian specialists to improve their techniques, encourage anyone wanting to begin studying ascidians, and enable readers to immediately apply the techniques to the organisms they research.

On July 12, 1969, Ruth Davis, a young American volunteer at Dr. Jane Goodall's famous chimpanzee research camp in the Gombe Stream National Park of Tanzania, East Africa, walked out of camp to follow a chimpanzee into the forest. Six days later, her body was found floating in a pool at the base of a high waterfall. With careful detail, The Ghosts of Gombe reveals for the first time the full story of day-to-day life in Goodall's wilderness camp--the people and the animals, the stresses and excitements, the social conflicts and cultural alignments, and the astonishing friendships that developed between three of the researchers and some of the chimpanzees--during the months preceding that tragic event. Was Ruth's death an accident? Did she jump? Was she pushed? In an extended act of literary forensics, Goodall biographer Dale Peterson examines how Ruth's death might have happened and explores some of the painful sequelae that haunted two of the survivors for the rest of their lives.
