"The Biology of Sharks and Rays" is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, tooth-like denticles that cover their entire bodies are present on only part of the rays' bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species' foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature. The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.

There are 10,500 species of bird worldwide and wherever they occur people marvel at their glorious colours and their beautiful songs. We also trap and consume birds of every kind. Yet birds have not just been good to eat. Their feathers, which keep us warm or adorn our costumes, give birds unique mastery over the heavens. Throughout history their flight has inspired the human imagination so that birds are embedded in our religions, folklore, music and arts. Vast in both scope and scale, Birds and People explores and celebrates this relationship and draws upon Mark Cocker's 40 years of observing and thinking about birds. Part natural history and part cultural study, it describes and maps the entire spectrum of our engagements with birds, drawing in themes of history, literature, art, cuisine, language, lore, politics and the environment. In the end, this is a book as much about us as it is about birds. Birds and People has been stunningly illustrated by one of Europe's best wildlife photographers, David Tipling, who has travelled in 39 countries on seven continents to produce a breathtaking and unique collection of photographs. The book is as important for its visual riches as it is for its groundbreaking content. Birds and People is also exceptional in that the author has solicited contributions from people worldwide. Personal anecdotes and stories have come from more than 650 individuals in 81 different countries. They range from university academics to Mongolian eagle hunters, and from Amerindian shamans to some of the most celebrated writers of our age. The sheer multitude of voices in this global chorus means that Birds and People is both a source book on why we cherish birds and a powerful testament to their importance for all humanity.

Authors from all over the world involved in their study and management offer reviews and case studies that provide insight into theory and practice. Brown Trout: Biology, Ecology and Management will provide scientists, researchers and experts in salmonids with attempts to uncover the exit from the complex maze of controversies and challenges associated with this species.
The central focus of this book is the avian respiratory system. The authors explain why the respiratory system of modern birds is built the way it is and works the way that it does. Birds have been and continue to attract particular interest to biologists. The more birds are studied, the more it is appreciated that the existence of human-kind on earth very much depends directly and indirectly on the existence of birds. Regarding the avian respiratory system, published works are scattered in biological journals of fields like physiology, behavior, anatomy/morphology and ecology while others appear in as far afield as paleontology and geology. The contributors to this book are world-renowned experts in their various fields of study. Special attention is given to the evolution, the structure, the function and the development of the lung-air sac system. Readers will not only discover the origin of birds but will also learn how the respiratory system of theropod dinosaurs worked and may have transformed into the avian one. In addition, the work explores such aspects as swallowing mechanism in birds, the adaptations that have evolved for flight at extreme altitude and gas exchange in eggs. It is a highly informative and carefully presented work that provides cutting edge scientific insights for readers with an interest in the respiratory biology and the evolution of birds.
This important and informative new book outlines and discusses details of the basic principles and methods that are central to any study of fish condition, from a fish ecology and fisheries biology perspective. Condition and Health Indicators of Exploited Marine Fishes describes the potential capacities of condition indicators, providing examples showing the use of these indicators to solve practical problems in connection with fish ecology and fisheries research. By focusing on wild fish populations, the book complements the increasing number of scientific works that are contributing to show how fish condition studies are key to reveal problems in marine aquaculture, the effects of pollution, fish disease, and the importance of fish in human nutrition and medicine. Condition and Health Indicators of Exploited Marine Fishes provides a comprehensive introduction to the study of fish condition that will assist advanced undergraduate and postgraduate students, researchers and professionals, working in marine ecology and biology, fisheries biology, environmental sciences and fish pathology. All universities and research establishments where biological and environmental sciences, fisheries and aquaculture are studied and taught should have copies of this book on their shelves.
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.

For much of his life, the closest Bob Tarte got to a nature walk was the stroll from parking lot to picnic table on family outings. But then a chance sighting of a dazzling rose-breasted grosbeak in wife-to-be Linda's backyard prompts a fascination with birds, which he had never cared about before in the least. Soon he is obsessed with spotting more and more of them-the rarer the better-and embarks on a bumpy journey to improve his bumbling birding skills. Along the way, Tarte offers readers a droll look at the pleasures and pitfalls he encounters, introduces a colorful cast of fellow birders from across the country, and travels to some of the premier birding sites in the Midwest, including Point Pelee, Magee Marsh, Tawas Point State Park, and even Muskegon Wastewater System. This funny, heartfelt memoir will appeal to birders of all skill levels as well as to anyone who knows and loves a birder.

Designed to help birders and banders identify, age, and sex all seventeen species of hummingbirds found in North America, this is the only identification guide devoted entirely to hummingbirds that includes up-close, easy-to-use illustrations. It also provides information on the eight species that have been reported but rarely seen in North America. On first viewing hummingbirds are often a blur of fast-moving color. However, when they perch and hover they can be observed, and the size, shape, and color; the proportions of the body, bill, throat, and tail; the wing feather pattern; and the birds' behavior are crucial to accurate identification. The author's concise descriptions and illustrations pinpoint all these features in clear, jargon-free language. Anyone who loves hummingbirds will welcome the information he provides.

Useful information about the interactions of humans and snakes is also covered: species that are likely to be found near houses, snakes as pets, what to do in case of a snake bite, and more.Clearly written, cleanly designed, and fun to use, the guide will promote a better understanding of the habitat needs of, and environmental challenges to, this fascinating group of animals.Features: Conservation-oriented approach Over 300 color photographs Nearly 50 distribution maps Clear descriptions of each species, including differences in the appearance of young and mature snakes Size charts, key identifiers (scales, body shape, patterns, and color), descriptions of habitat, behavior and activity, food and feeding, reproduction, predators and defense, and conservation
Insects are more similar in structure and physiology to mammals than plants or fungi. Consequently, insecticides are often of greater toxicity to mammals than herbicides. This is particularly the case with neurotoxins. However, some insecticides are targeted at structures or hormonal systems specific to insects (insect growth regulators/chitin synthesis inhibitors) so are less harmful but can still be mildly haematotoxic. There are, therefore, issues specific to insecticides, which do not occur with other pesticides - hence the need for a book specifically on insecticide toxicology in mammals. The book starts with general issues relating to the mammalian toxicity of insecticides, including target/non-target specificity, nomenclature and metabolism of insecticides. It then goes on to discuss specific types of insecticides including: organochlorines; anticholinesterases; pyrethrum and synthetic pyrethroids; nicotine and the neonicotinoids; insect growth regulators/ecdysone agonists/chitin synthesis inhibitors; insecticides of natural origin; biological insecticides; and insecticides used in veterinary medicine.

"Fast claiming his place as one of the country's finest natural history writers, Pyle takes to the hills in search of Bigfoot in this absorbing, classily written field report. Pyle makes all the right connections. Best of all, he loves a good mystery and is smart enough, open and radical enough, to never say never." --Kirkus Reviews More than 20 years after Where Bigfoot Walks was originally published, Dr. Robert Michael Pyle, a Yale-trained ecologist and a Guggenheim fellow, returns with a brand-new chapter that brings his work on the legend of Bigfoot into the new century Awarded a Guggenheim to investigate the legends of Sasquatch, Dr. Robert Pyle trekked into the unprotected wilderness of the Dark Divide near Mount St. Helens, where he discovered both a giant fossil footprint and recent tracks. He searched out Indians who told him of an outcast tribe, the Seeahtiks, who had not fully evolved into humans. He attended Sasquatch Daze, where he met scientists, hunters, and others who have devoted their lives to the search, and realized that "these guys don't want to find Bigfoot--they want to be Bigfoot!" A handful of open-minded biologists and anthropologists countered the tabloids he studied, while rogue Forest Service employees and loggers swore of an industry conspiracy to deep-six accounts of unknown, upright hominoid apes among us. In the years since publication, the author's fresh experiences and finds--detailed in an all-new chapter which includes an evaluation of recent DNA evidence from Bigfoot hair and scat, the study of speech phonemes in the "Sierra Sounds" purported Bigfoot recordings, Pyle's examination of the impact of the wildly popular Animal Planet series Bigfoot Hunters, the reemergence of the famous Bob Gimlin into the Bigfoot community, and more--have kept his own mind wide open to one of the biggest questions in the land.

Henry Baker Tristram was a surprising and remarkable man: explorer, ornithologist, and priest. With his wild beard (for which he required special permission from his bishop) he undertook expeditions to the Sahara and Palestine at a time when doing so was even more fraught with danger than it is today. As a founding member of the British Ornithologists' Union (BOU), he contributed regularly to its journal, Ibis, as well as other scientific journals. Tristram's nickname in the BOU was "Sacred Ibis". Tristram was a collector par excellence, acquiring extensive collections running to tens of thousands of specimens, primarily of birds, but also of plants, fish, mammals, insects, molluscs, geological samples and archaeological material. He was the first scientist to support Charles Darwin in print, and became a Fellow of the Royal Society in 1868 supported by his great friend Alfred Newton as well as Darwin. Professor J. B. Cragg, an eminent Zoologist at Durham University, described Tristram as "the most important biological scientist to have emerged from Durham." Tristram took part in the famous "Oxford debate" between Bishop Wilberforce of Oxford and Thomas Huxley. This led to the unfortunate and incorrect assumption that Tristram subsequently gave up his support of Darwin. This book follows Tristram's epic adventures and love for birds-from his boyhood on the moors of Northumberland to his time as a Residentiary Canon of Durham Cathedral-and the people that influenced him-from his dislike of Gladstone whom he met as a fresher in Oxford to the offer of the Bishopric of Jerusalem by Disraeli (which Tristram declined). In the book are over 80 colour plates and a reproduction of Darwin's first letter to Tristram. GBP10 from each sale of the hardback edition of Sacred Ibis made through this website will be donated to the Grey College Trust. Sales via other retailers will generate a donation of GBP5 per copy. Perhaps Tristram's greatest contribution to science was his Fauna and Flora of Palestine. On his deathbed he wrote to his great friend Alfred Newton-who stood down temporarily from his Fellowship of the Royal Society so that Tristram might be elected-thanking him for his friendship. He and Newton had been a great ornithological partnership and were responsible not only for the development of ornithology as a science but also for the establishment of the conservation movement. Not everyone these days will approve of his collecting activities, but this is what he did and what was necessary to the development of science in Victorian times. Had the big majority of present-day biologists lived in those times they would undoubtedly have acted similarly, but few would have been so successful. As his granddaughter wrote, Tristram may not have been a great churchman, but he was a great ornithologist.
The behaviour of domesticated animals is a subject of great importance to students of animal behaviour and veterinary medicine, as well as interested pet owners. This book presents an engaging overview of the behaviour of the domestic cat, adopting both a mechanistic and functional approach. Physiological, developmental and psychological aspects are addressed, including domestication, the development of the senses, learning, communication and feeding behaviour. The authors build on these themes to discuss social behaviour, hunting and predation, cat-human interactions and welfare. Fully updated throughout, this new edition also includes two new chapters on behavioural disorders due to pathologies and from misdirected natural behaviour. It is an essential source of cat behaviour information for students, ethologists, veterinarians and pet owners.
