Emperors of the Deep - The Mysterious and Misunderstood World of the Shark (Paperback): William McKeever Emperors of the Deep - The Mysterious and Misunderstood World of the Shark (Paperback)
William McKeever
R229 Discovery Miles 2 290 Ships in 12 - 17 working days

Sharks are ruthlessly efficient predators, the apex of 450 million years of evolution. They are older than trees, have survived five extinction events and are essential to maintaining balanced ocean ecosystems, but how much do we really know about their lives? The first book to reveal the hidden world of sharks, Emperors of the Deep draws upon the latest scientific research to examine four species in detail – mako, tiger, hammerhead and great white – as never before. An eye-opening tour of shark habitats ranges from the coral reefs of the Central Pacific where great whites mysteriously congregate every autumn in what researchers call a festival for sharks, to tropical mangrove forests where baby lemon sharks play in social groups and to the frigid waters of the North Atlantic, home to 400-year-old Greenland sharks, the world’s longest-lived vertebrates. McKeever also traces the evolution of the myth of the ‘man-eater’ and exposes the devastating effects of the fishing industry on shark populations: In 2018 only four people died in shark attacks while we killed 100 million sharks. At once a journey through the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates these iconic predators that continue to capture our imagination – and that desperately need our help to survive.

A beautifully illustrated introduction to the incredible variety of bees from around the world When many people think of bees, they are likely to picture the western domesticated honey bee, insects that live in large, socially complex societies inside a hive with a single queen and thousands of workers. But this familiar bee is just one of more than 20,000 species of bees-and almost none of the others is anything like it. In Bees of the World, Laurence Packer, one of the world's foremost experts on wild bees, celebrates the amazing diversity of bees-from size and appearance to nests and social organization. Providing clear, accurate accounts of the seven bee families, Bees of the World presents all the key information on generic characteristics, habits, and habitat, illustrated with incredible and often rare photographs that show bees in their natural habitats-foraging, nesting, raising their young, and more. The book reveals the secrets of these extraordinary insects as well as their importance in the global ecosystem and the ways humans can help protect them. Provides a richly illustrated exploration of bees from around the world Examines more than 100 genera of bees, giving a taste of the remarkable breadth of bee appearance and biology Explores bee anatomy, behavior, classification, evolution, life cycle, and habitats

Canine Confidential - Why Dogs Do What They Do (Paperback): Marc Bekoff Canine Confidential - Why Dogs Do What They Do (Paperback)
Marc Bekoff
R498 R420 Discovery Miles 4 200 Save R78 (16%) Ships in 10 - 15 working days

For all the love and attention we give dogs, much of what they do remains mysterious. Just think about different behaviors you see at a dog park: We have a good understanding of what it means when dogs wag their tails--but what about when they sniff and roll on a stinky spot? Why do they play tug-of-war with one dog, while showing their bellies to another? Why are some dogs shy, while others are bold? What goes on in dogs' heads and hearts--and how much can we know and understand? Canine Confidential has the answers. Written by award-winning scientist--and lifelong dog lover--Marc Bekoff, it not only brilliantly opens up the world of dog behavior, but also helps us understand how we can make our dogs' lives the best they can possibly be. Rooted in the most up-to-date science on cognition and emotion--fields that have exploded in recent years--Canine Confidential is a wonderfully accessible treasure trove of new information and myth-busting. Peeing, we learn, isn't always marking; grass-eating isn't always an attempt to trigger vomiting; it's okay to hug a dog--on their terms; and so much more. There's still much we don't know, but at the core of the book is the certainty that dogs do have deep emotional lives, and that as their companions we must try to make those lives as rich and fulfilling as possible. It's also clear that we must look at dogs as unique individuals and refrain from talking about "the dog." Bekoff also considers the practical importance of knowing details about dog behavior. He advocates strongly for positive training--there's no need to dominate or shame dogs or to make them live in fear--and the detailed information contained in Canine Confidential has a good deal of significance for dog trainers and teachers. He also suggests that trainers should watch and study dogs in various contexts outside of those in which they are dealing with clients, canine and human, with specific needs. There's nothing in the world as heartwarming as being greeted by your dog at the end of the workday. Read Canine Confidential, and you'll be on the road to making your shared lives as happy, healthy, and rewarding as they can possibly be.

Nutrition and the Welfare of Farm Animals (Hardcover, 1st ed. 2016): Clive J.C. Phillips Nutrition and the Welfare of Farm Animals (Hardcover, 1st ed. 2016)
Clive J.C. Phillips
R4,427 Discovery Miles 44 270 Ships in 10 - 15 working days

This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal's behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock. This book will provide a much-needed review of the relationships between nutrition and the welfare of farm animals.

A Philosopher with Nature (Hardcover): Benjamin Kidd A Philosopher with Nature (Hardcover)
Benjamin Kidd
R3,916 Discovery Miles 39 160 Ships in 12 - 17 working days

Benjamin Kidd (1858-1916), well-known for his ground-breaking application of social Darwinism in his premier work Social Evolution (1894), was a sociologist and a keen observer of nature. First published posthumously in 1921, A Philosopher with Nature is a collection of Kidd's most profound writings concerning natural habitats. Although the book is not to be considered scientific, Kidd's method of uniting biology and sociology sheds remarkable insights into the animal kingdom. This title is suitable for both students of Anthropology and Sociology.

Neil Middleton, Andrew Froud, Keith French
R1,153 Discovery Miles 11 530 Ships in 12 - 17 working days

The social calls of bats are an area about which relatively little is known, with more research still required to expand our understanding. However, these calls are increasingly recognised as a useful aid to identification: they appear to be species specific and are indicative of behaviour – as in territorial activity of males during the mating season. Because the gathering and interpretation of bat echolocation data are a matter of course during research, conservation and consultancy, it is a logical progression to build momentum behind the consideration of social calls in mainstream bat-related work. A better understanding of this subject could mean that non-intrusive survey methods are developed, ensuring that what is being observed is, as far as possible, purely natural behaviour. In turn this will contribute to better interpretation and more suitable mitigation, compensation and/or enhancement solutions. The book summarises what is understood so far about social calls of the bat species occurring in Britain and Ireland, and north-west Europe. This new edition has been updated and expanded throughout, now containing: foreword by the bat authority Michel Barataud, author of Acoustic Ecology of European Bats   almost double the number of figures and tables as appeared in the first edition completely overhauled call library, all in full spectrum format, with new additional examples  three entirely new chapters, covering bat-related acoustics, settings for social interaction, and survey guidelines The material will be useful to people carrying out bat studies, at whatever level and for whatever purpose, and will also encourage others to undertake further research. What's more, social calls are fascinating to listen to: they are, after all, produced with listeners in mind (other bats). In light of this, the book is accompanied by an extensive downloadable library of sound files which offer a unique gateway into the private life of bats. 

Invasive Species: A Very Short Introduction (Paperback): Julie Lockwood, Dustin J. Welbourne Invasive Species: A Very Short Introduction (Paperback)
Julie Lockwood, Dustin J. Welbourne
R268 R217 Discovery Miles 2 170 Save R51 (19%) Ships in 9 - 15 working days

Today there is no place on Earth that does not harbour invasive exotic species. Invasive plants and animals can be found on every continent, including Antarctica, and within all waterbodies, including all oceans. In our increasingly connected world, with speedy commercial and recreational travel and the global movement of biological matter for food, invasive species are showing up at such a fast rate that there is no way to accurately count how many currently exist or how many are likely to emerge in the coming decades. Monitoring these species and controlling their spread is essential, as we increasingly understand the negative impacts they pose: their threat to our health; the toll they take on our commercial production; and the threat they pose to native ecosystems. This Very Short Introduction provides a clear definition of an invasive species, and considers the myriad ways they are moved around the globe, and the ecological, social, and economic impacts they often impose. Exploring the way Earth's biodiversity is being affected by global change, Julie Lockwood also discusses policy and management approaches to combating the ill-effects of invasive species, and how invasive species fit within the broader context of environmental change. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

R4,427 Discovery Miles 44 270 Ships in 10 - 15 working days

The collection of chapters in this book present the concept of matched filters: response characteristics "matching" the characteristics of crucially important sensory inputs, which allows detection of vital sensory stimuli while sensory inputs not necessary for the survival of the animal tend to be filtered out, or sacrificed. The individual contributions discuss that the evolution of sensing systems resulted from the necessity to achieve the most efficient sensing of vital information at the lowest possible energetic cost. Matched filters are found in all senses including vision, hearing, olfaction, mechanoreception, electroreception and infrared sensing and different cases will be referred to in detail.

Among the offspring of humans and other animals are occasional individuals that are malformed in whole or in part. The most grossly abnormal of these have been referred to from ancient times as monsters, because their birth was thought to foretell doom; the less severely affected are usually known as anomalies. This volume digs deeply into the cellular and molecular processes of embryonic development that go awry in such exceptional situations. It focuses on the physical mechanisms of how genes instruct cells to build anatomy, as well as the underlying forces of evolution that shaped these mechanisms over eons of geologic time. The narrative is framed in a historical perspective that should help students trying to make sense of these complex subjects. Each chapter is written in the style of a Sherlock Holmes story, starting with the clues and ending with a solution to the mystery.

Human-Horse Relations and the Ethics of Knowing (Hardcover): Rosalie Jones McVey Human-Horse Relations and the Ethics of Knowing (Hardcover)
Rosalie Jones McVey
R3,561 Discovery Miles 35 610 Ships in 9 - 15 working days

This book explores how equestrians are highly invested in the idea of profound connection between horse and human and focuses on the ethical problem of knowing horses. In describing how ‘true’ connection with horses matters, Rosalie Jones McVey investigates what sort of thing comes to count as a ‘good relationship’ and how riders work to get there. Drawing on fieldwork in the British horse world, she illuminates the ways in which equestrian culture instils the idea that horse people should know their horses better. Using horsemanship as one exemplary instance where ‘truth’ holds ethical traction, the book demonstrates the importance of epistemology in late modern ethical life. It also raises the question of whether, and how, the concept of truth should matter to multispecies ethnographers in their ethnographic representations of animals.

Instinct, Environment and Behaviour (Hardcover): Stephen Lea Instinct, Environment and Behaviour (Hardcover)
Stephen Lea
R3,162 Discovery Miles 31 620 Ships in 12 - 17 working days

What can the evolution of animal behaviour tell us about human behaviour? More specifically, how good an account of animal behaviour can we give in terms of evolution, and how do humans fit in with or deviate from the pattern established for other animals? The biological approach to the study of animal behaviour has important implications for psychology, but it is distinctly different. Originally published in 1984, this book provides a basic introduction to biological theories about behaviour, from the classic ethological tradition of Lorenz and Tinbergen to the later sociobiological approach. The principles of experimentation and research involved are assessed critically, especially with regard to their implications for the study of human behaviour. Written specifically for those with little biological knowledge, this book will still be of interest to students of biology and introductory psychology alike.

Here's a quick and quirky identification guide to animal dung or droppings.

Each animal group (carnivores, primates, antelope, rats and mice, reptiles, birds) is briefly introduced; but the main focus of this book is the photographs, mostly life-size. These images enable immediate identification of the animals responsible for the droppings. To confirm identity, summary tables give details of average width, length and typical contents of droppings (feathers, twigs, leaves, sand, etc.).

This should become a recommended reference for rangers and field guides in the region; and it will be of use to anyone with an interest in wildlife, and even to those who simply enjoy walking in the wild and observing the tracks and signs they encounter.

Amagama Izinyoni: Zulu Names of Birds lists all the bird species found in KwaZulu-Natal and surrounds, gives the proposed standardised Zulu name for each species, and explains the underlying meaning and how the name came into being. All earlier names for these birds, even if no longer in current use, have been recorded here, making this a historical repository of Zulu bird names as well. This book is the result of the six-year Zulu Bird Name Project. Between 2013 and 2018, annual workshops, organised and facilitated by the three authors, brought together a total of eighteen mother-tongue Zulu-speaking bird experts to research the names of bird species present in the Zulu-speaking area of South Africa. At the start of the project, only approximately 40 per cent of the bird species of this area had species-specific Zulu names; by the end of the project all 550 species had unique names. The comprehensive introduction explains the methodology used in the Zulu bird name workshops, providing a template for linguists and ornithologists who might wish to do similar bird-naming exercises in the other African languages of southern Africa. The introduction also provides some linguistic and onomastic insights into bird naming generally and Zulu bird names in particular.

John James Audubon - The Nature of the American Woodsman (Paperback): Gregory Nobles John James Audubon - The Nature of the American Woodsman (Paperback)
Gregory Nobles
R671 Discovery Miles 6 710 Ships in 12 - 17 working days

John James Audubon's The Birds of America stands as an unparalleled achievement in American art, a huge book that puts nature dramatically on the page. With that work, Audubon became one of the most adulated artists of his time, and America's first celebrity scientist. In this fresh approach to Audubon's art and science, Gregory Nobles shows us that Audubon's greatest creation was himself. A self-made man incessantly striving to secure his place in American society, Audubon made himself into a skilled painter, a successful entrepreneur, and a prolific writer, whose words went well beyond birds and scientific description. He sought status with the "gentlemen of science" on both sides of the Atlantic, but he also embraced the ornithology of ordinary people. In pursuit of popular acclaim in art and science, Audubon crafted an expressive, audacious, and decidedly masculine identity as the "American Woodsman," a larger-than-life symbol of the new nation, a role he perfected in his quest for transatlantic fame. Audubon didn't just live his life; he performed it. In exploring that performance, Nobles pays special attention to Audubon's stories, some of which-the murky circumstances of his birth, a Kentucky hunting trip with Daniel Boone, an armed encounter with a runaway slave-Audubon embellished with evasions and outright lies. Nobles argues that we cannot take all of Audubon's stories literally, but we must take them seriously. By doing so, we come to terms with the central irony of Audubon's true nature: the man who took so much time and trouble to depict birds so accurately left us a bold but deceptive picture of himself.

Peacocks & Picathartes is a celebration of the diversity of African birds, focusing on families that occur only in Africa as well as iconic families and species that, despite having close relatives in other parts of the world, seem to embody something of Africa.

Watson’s anecdotal style captures vividly his encounters with prized species, such the secretive White-necked Picathartes and the elusive Congo Peacock. He conveys the sheer delight mousebirds take in ‘being what they are’, and reveals the surprise discovery in 1991 of a new partridge in Tanzania’s Udzungwa Mountains.

Drawing on precolonial and current-day avian accounts, he offers his own insights based on a lifetime of personal observations in the wilds of Africa – recounting unforgettable expeditions, quirky bird behaviour, jittery taxonomy, moments of rare good luck – and much more.

Both informative and entertaining, this book captures the essence of African bird life, and will appeal to bird enthusiasts across the spectrum.

Bryozoan Paleobiology (Paperback): Paul D Taylor Bryozoan Paleobiology (Paperback)
Paul D Taylor
R2,427 Discovery Miles 24 270 Ships in 12 - 17 working days

Bryozoa are among the most abundant yet least understood of phyla in the fossil record. These exclusively colonial animals can be traced back to the Ordovician as fossils and are common elements of sediments deposited in shallow marine environments. On occasion their calcareous skeletons are sufficiently numerous to produce bryozoan limestones. The potential of bryozoans in facies analysis, and their use in macroevolutionary studies, have both been widely recognised, but to date have been incompletely exploited. Bryozoan Paleobiology brings together the scattered research on living and fossil bryozoans in broad and profusely illustrated overview that will help students and researchers alike in understanding this fascinating group of animals. Beginning with the basics of bryozoan morphology, ecology and classification, the book progresses from the smallest scale of skeletal ultrastructure, to the largest of bryozoan distributions in time and space. On the way, topics such as the origin of zooidal polymorphism and macroevolutionary trends in colony forms are covered. Case studies illuminate these topics, and areas in which further research is particularly required are highlighted.
