The Birds of Zambia - An Atlas and Handbook (Paperback): Robert J. Dowsett, Dylan R. Aspinwall, Francoise Dowsett-Lemaire The Birds of Zambia - An Atlas and Handbook (Paperback)
Robert J. Dowsett, Dylan R. Aspinwall, Francoise Dowsett-Lemaire
R711 Discovery Miles 7 110 Shipped within 7 - 12 working days

This book presents detailed accounts of the more than 750 species known (among which there are 100 migrants from the northern hemisphere) in Zambia. Extensive fieldwork by the authors and many collaborators means that the maps (for all species except vagrants) present a clear picture of distribution in this country of some 750,000 sq. km. The text complements the maps, with a synthesis of what is known of ecology, status, movements, breeding seasons, taxonomy and conservation concerns. This book is not intended as a field guide (there are few illustrations of birds), but as a handbook and distribution atlas, highlighting the status, distribution and conservation of each species. More than 900 published references are cited, and there are details of ringing recoveries and a gazetteer of more than 800 localities. In 70 pages, the introductory chapters review the vegetation and major bird habitats, biogeography, migration, conservation and the history of ornithological exploration in Zambia. Sixteen pages of colour photos illustrate the habitats of Zambia as well as over a dozen of the more typical bird species (including the endemic Black-cheeked Lovebird and Chaplin's Barbet). Zambia is at the centre of the Zambezian region of endemism, and its woodlands, dry forests and dambos harbour 57 of the 64 bird species confined to this biome. This is the sixth account of the birds of Zambia (ex-Northern Rhodesia) since the first (Pitman 1934), and it updates and expands its immediate predecessor The Birds of Zambia (Benson, Brooke, Dowsett & Irwin, 1971).

An Indomitable Beast - The Remarkable Journey of the Jaguar (Hardcover, 2): Alan Rabinowitz An Indomitable Beast - The Remarkable Journey of the Jaguar (Hardcover, 2)
Alan Rabinowitz
R562 R411 Discovery Miles 4 110 Save R151 (27%) Shipped within 8 - 13 working days

The jaguar is one of the most mysterious and least-known big cats of the world. The largest cat in the Americas, it has survived an onslaught of environmental and human threats partly because of an evolutionary history unique among wild felines, but also because of a power and indomitable spirit so strong, the jaguar has shaped indigenous cultures and the beliefs of early civilizations on two continents. In An Indomitable Beast: The Remarkable Journey of the Jaguar, big-cat expert Alan Rabinowitz shares his own personal journey to conserve a species that, despite its past resilience, is now on a slide toward extinction if something is not done to preserve the pathways it prowls through an ever-changing, ever-shifting landscape dominated by humans. Rabinowitz reveals how he learned from newly available genetic data that the jaguar was a single species connected genetically throughout its entire range from Mexico to Argentina, making it unique among all other large carnivores in the world. In a mix of personal discovery and scientific inquiry, he sweeps his readers deep into the realm of the jaguar, offering fascinating accounts from the field. Enhanced with maps, tables, and colour plates, An Indomitable Beast brings important new research to life for scientists, anthropologists, and animal lovers alike. This book is not only about jaguars, but also about tenacity and survival. From the jaguar we can learn better strategies for saving other species and also how to save ourselves when faced with immediate and long-term catastrophic changes to our environment.

Endangered Sea Turtles (Paperback): Bobbie Kalman Endangered Sea Turtles (Paperback)
Bobbie Kalman
R145 R109 Discovery Miles 1 090 Save R36 (25%) Shipped within 7 - 11 working days

Ages 6 to 12 years. To lay eggs, a sea turtle swims thousands of miles to the beach where she was born. This long journey is fraught with danger. In many cases, the beaches are now full of hotels, people, and lights, which fool sea turtles into going the wrong way after they have laid their eggs. The journey of the hatchlings is even more harrowing, and very few make it to the ocean. In this fascinating book, children will learn about: the different species of sea turtles, their bodies, life cycles, migration, behaviour, and diets; why they are endangered; how people are helping them.

Primate Communication - A Multimodal Approach (Paperback, New): Katja Liebal, Bridget M. Waller, Anne M. Burrows, Katie E.... Primate Communication - A Multimodal Approach (Paperback, New)

R864 Discovery Miles 8 640 Shipped within 7 - 12 working days

Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions to initiate play. Primate Communication brings together research on all forms of interchange and discusses what we know about primate communication via vocal, gestural, facial, olfactory and integrated multimodal signals in relation to a number of central topics. It explores the morphological, neural and cognitive foundations of primate communication through discussion of cutting-edge research. By considering signals from multiple modalities and taking a unified multimodal approach, the authors offer a uniquely holistic overview of primate communication, discussing what we know, what we don't know and what we may currently misunderstand about communication across these different forms. It is essential reading for researchers interested in primate behaviour, communication and cognition, as well as students of primatology, psychology, anthropology and cognitive sciences.

Beautiful Whale (Hardcover): Austin Bryant Beautiful Whale (Hardcover)
Austin Bryant; Introduction by Sylvia A. Earle 1
R844 R542 Discovery Miles 5 420 Save R302 (36%) Shipped within 7 - 12 working days

Photographer and conservationist Bryant Austin had long searched for an impactful way to inspire change in whaling nations. For many years, he searched for a way to photograph whales in the wild that would capture their awe inspiring beauty, grace and intelligence. A chance encounter with a humpback calf and mother finally opened Austin's eyes and helped him to develop a novel way of producing high resolution, life size photography of these astounding creatures. Spending weeks with groups of whales off Tonga, Dominica, and the Great Barrier Reef in Australia, Austin immerses himself in the water for many hours each day, waiting patiently for whales to approach him. He remains motionless, allowing humpback, sperm and minke whales that are sometimes 100 feet in length and weigh as much as 55 tons to come within ten feet of him. This allows him to create detailed, intimate portraits of his subjects. Austin's first book, Beautiful Whale presents remarkable close ups of whales, including a special focus on their eyes, as well as full body portraits created by compiling hundreds of images. The book includes a foreword by oceanographer Dr. Sylvia Earle.

This atlas is currently the most systematic and comprehensive atlas of the tree shrew brain. The purpose of this book is to help scientists acquire accurate coordinates of the brain regions of the tree shrew, which is becoming a popular animal model for a variety of human diseases. This atlas contains series of 192 coronal sections, 36 sagittal sections, and 49 horizontal sections using Nissl staining or acetylcholinesterase histochemistry as well as a series of diagrams in stereotaxic coordinates. Original photomicrographs are obtained at single-cell resolution. In addition, we also referred to magnetic resonance images acquired at 250 um intervals with a magnetic resonance scanner 9.4T. Many brain structures are first identified in tree shrews and accurately presented in a stereotaxic coordinate system. The Bregma coordinates system is used for the first time in this tree shrew brain atlas. The atlas represents the collaboration between two indispensable skills of brain research, neuroanatomy and stereotaxic surgery. It will be extensively used in neuroscience research, particularly tree shrew brain study, and will help graduate students and researchers understand brain anatomy and acquire accurate reference coordinates.

Lizards in an Evolutionary Tree - Ecology and Adaptive Radiation of Anoles (Paperback): Jonathan B. Losos Lizards in an Evolutionary Tree - Ecology and Adaptive Radiation of Anoles (Paperback)

Adaptive radiation, which results when a single ancestral species gives rise to many descendants, each adapted to a different part of the environment, is possibly the single most important source of biological diversity in the living world. One of the best-studied examples involves Caribbean "Anolis "lizards. With about 400 species, "Anolis "has played an important role in the development of ecological theory and has become a model system exemplifying the integration of ecological, evolutionary, and behavioral studies to understand evolutionary diversification. This major work, written by one of the best-known investigators of "Anolis, "reviews and synthesizes an immense literature. Jonathan B. Losos illustrates how different scientific approaches to the questions of adaptation and diversification can be integrated and examines evolutionary and ecological questions of interest to a broad range of biologists.

An authoritative and entertaining exploration of Australia's distinctive birds and their unheralded role in global evolution Renowned for its gallery of unusual mammals, Australia is also a land of extraordinary birds. But unlike the mammals, the birds of Australia flew beyond the continent's boundaries and around the globe many millions of years ago. This eye-opening book tells the dynamic but little-known story of how Australia provided the world with songbirds and parrots, among other bird groups, why Australian birds wield surprising ecological power, how Australia became a major evolutionary center, and why scientific biases have hindered recognition of these discoveries. From violent, swooping magpies to tool-making cockatoos, Australia's birds are strikingly different from birds of other lands-often more intelligent and aggressive, often larger and longer-lived. Tim Low, a renowned biologist with a rare storytelling gift, here presents the amazing evolutionary history of Australia's birds. The story of the birds, it turns out, is inseparable from the story of the continent itself and also the people who inhabit it.

Everywhere we go there are birds, and they all have mysteries to be unravelled. These mysteries include the way they look, from bizarre to apparently mundane, why they live where they live, and the things they do, many of which are far too incredible ever to be imagined as fiction. Birds in Their Habitats is a collection of stories and experiences, which introduce fascinating aspects of birdlife, ecology and behaviour. Informed by a wealth of historical and contemporary research, Ian Fraser takes the reader on a journey through four continents: from places as unfamiliar as the Chonos Archipelago of southern Chile and the arid Sahel woodlands of northern Cameroon to those as familiar as a suburban backyard. This is a book of discovery of birds and the places they live. And with humour and personal insight, it is a book about the sometimes strange world of the people who spend a life absorbed in birds. FEATURES: Engaging and entertaining text written by one of Australia's best natural history writers. This `birding travelogue' will take readers on a journey of discovery through the far-flung habitats and fascinating birds of the world.

Birds have not been known for their high IQs, which is why a person of questionable intelligence is sometimes called a "birdbrain." Yet in the past two decades, the study of avian intelligence has witnessed dramatic advances. From a time when birds were seen as simple instinct machines responding only to stimuli in their external worlds, we now know that some birds have complex internal worlds as well. This beautifully illustrated book provides an engaging exploration of the avian mind, revealing how science is exploding one of the most widespread myths about our feathered friends-and changing the way we think about intelligence in other animals as well.Bird Brain looks at the structures and functions of the avian brain, and describes the extraordinary behaviors that different types of avian intelligence give rise to. It offers insights into crows, jays, magpies, and other corvids-the "masterminds" of the avian world-as well as parrots and some less-studied species from around the world. This lively and accessible book shows how birds have sophisticated brains with abilities previously thought to be uniquely human, such as mental time travel, self-recognition, empathy, problem solving, imagination, and insight.Written by a leading expert and featuring a foreword by Frans de Waal, renowned for his work on animal intelligence, Bird Brain shines critical new light on the mental lives of birds.

A comprehensive natural history of nature's smallest bird species. "The spectacular photography of Michael and Patricia Fogden reveals the diversity, beautiful colours and movement of these unique birds." Publishers Weekly. The tiny hummingbird has long been a source of fascination for birdwatchers and naturalists alike. They number 300 species and Ronald Orenstein has a passion for all of them. Hummingbirds are the smallest birds in the world. A hummingbird egg is the size of a pea, barely, and the chick that emerges will be smaller than a penny, if that. But these tiny birds pack a powerful engine: a hummingbird's heart beats more than 1,200 times per minute. Nicknamed the "avian helicopter," a hummingbird's wings beat from 70 times per second in direct flight, to more than 200 times per second when diving. Not surprisingly, that whirlwind of wing power creates a humming sound. To fuel such energy, hummingbirds must eat as much as eight times their body weight on a daily basis, which means visiting an average of 1,000 flowers - every day - to get enough nectar. Hummingbirds are found in North, Central and South America, with the greatest number in Ecuador, although some species breed as far north as Canada. Most species migrate from Mexico to Alaska, a distance of more than 5,000 miles. In this book Orenstein covers all aspects of hummingbird natural history, their relationship with the plants on which they feed, the miracle of their flight, their elaborate social life and nesting behaviour, and their renowned feats of migration. More than 170 colour photographs of these magnificent creatures, taken in the wild, adorn the pages of Hummingbirds. Ornithologists and natural history readers alike will gain new insight into the tiny bird and revel in the stunning images.

This book provides everything from basic knowledge to the recent understandings of avian reproductive physiology, covering many unique aspects. It will inspire avian biologists as well as researchers in varied fields and will offer important steps towards better fertilization success in birds.In spite of the recent remarkable developments in modern technology, a comprehensive understanding of the reproductive mechanisms is still far in the future due to the diverse reproductive tactics in vertebrates. Birds have highly refined reproductive strategies and some of those strategies are unique to birds. However, together with ongoing progress of the genome analysis of birds and the crying need for further increase in meat and egg production, research on avian reproduction is now accelerating and becoming more important.With contributions by leading scientists, the book explains avian primordial germ cells; the sex-determining mechanism; reproductive endocrinology and immunology; sperm, egg, and egg coat; sperm-egg interaction; polyspermic fertilization; seasonal reproduction; social triggers; hormonal and behavioral changes; broodiness; oviductal sperm storage; and biotechnology. This book is recommended for all researchers and students who are interested in birds or reproduction.

R1,818 Discovery Miles 18 180 Shipped within 7 - 12 working days

Suppose you were designing a marine mammal. What would you need to think about to allow it to live in the ocean? How would you keep it warm? What would you design to allow it to dive for very long periods to extreme depths? Where would it find water to drink? How would you minimize the cost of swimming, and how would it find its prey in the deep and dark? These questions and more are examined in detail throughout this book. Marine Mammal Physiology: Requisites for Ocean Living is the first textbook focused on how marine mammals live in the sea from a physiological point of view. It explores the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. Unlike many publications and books that cover these species from almost all perspectives, this textbook takes a step back to focus on the physiological and biochemical characteristics that have allowed these mammals as a group to exploit effectively the marine environment that is so hostile to humans. The chapter topics are grouped into major themes: diving and locomotion, nutrition and energetics, reproduction, sensory systems, and environmental interactions. Each chapter is arranged around a common perspective and theme: the big picture challenge and summary and what is known specifically by order. To aid you even further, the authors include a "Toolbox" section in each chapter where they discuss the newest methods for understanding and working on the physiology of marine mammals.

This is the first paperback version of the second edition of the popular A Guide to the Birds of Panama. In the second edition, published in 1989, the authors expanded information on the birds of Costa Rica, Nicaragua, and Honduras: approximately 200 new species were added to the material in the 1976 edition. Over 300 additional species, some of them Panamanian, were illustrated. Sixteen new plates were added, and three of the original plates were replaced by improved versions. Throughout the book changes were made to accommodate the explosion in knowledge of the birds of Panama and nearby areas and of neotropical birds in general. The basic sequence and systematics of the AOU 1983 Check-list were adopted. Also included in the revised edition was expanded and updated information on birdfinding in Panama, prepared with the assistance of two of Panama's best resident birders. The book also contains a special section outlining developments in Panama ornithology and conservation.

The vertebrate skeleton is one of nature's most amazing feats. Composed of cartilage and bone, it forms the supportive structure for all the remaining aspects of our anatomy. Stripped of skin, we can see the body's fascinating underlying architecture. In this one-of-a-kind book, biologist and skeletal reconstructionist Steve Huskey lays bare the vertebrate skeleton, providing a guided tour of the nuanced differences among the many featured vertebrate species. Using skeletal preparations he has spent decades assembling, Huskey helps us understand why animals live the way they do. He shows us the jaw and fang structures that allow venomous snakes to both kill and consume their prey whole. We see that the eastern mole is built like a weightlifter, allowing it to "swim through soil." Startling images demonstrate that the odd-looking trumpetfish is built not for music but for suction, with a skull that expands to vacuum in its prey. The pages of The Skeleton Revealed illuminate not only the elegance of each skeleton, but also the natural history story each skeleton tells. Come along-let's take a voyage through the boneyard.
