R664 R610 Discovery Miles 6 100 Save R54 (8%) Shipped within 7 - 11 working days

A single species of fly, Drosophila melanogaster, has been the subject of scientific research for more than one hundred years. Why does this tiny insect merit such intense scrutiny? Drosophila's importance as a research organism began with its short life cycle, ability to reproduce in large numbers, and easy-to-see mutant phenotypes. Over time, laboratory investigation revealed surprising similarities between flies and other animals at the level of genes, gene networks, cell interactions, physiology, immunity, and behavior. Like humans, flies learn and remember, fight microbial infection, and slow down as they age. Scientists use Drosophila to investigate complex biological activities in a simple but intact living system. Fly research provides answers to some of the most challenging questions in biology and biomedicine, including how cells transmit signals and form ordered structures, how we can interpret the wealth of human genome data now available, and how we can develop effective treatments for cancer, diabetes, and neurodegenerative diseases. Written by a leader in the Drosophila research community, First in Fly celebrates key insights uncovered by investigators using this model organism. Stephanie Elizabeth Mohr draws on these "first in fly" findings to introduce fundamental biological concepts gained over the last century and explore how research in the common fruit fly has expanded our understanding of human health and disease.

Behavioural Neuroscience (Paperback): Sean Commins Behavioural Neuroscience (Paperback)
Sean Commins
R799 R662 Discovery Miles 6 620 Save R137 (17%) Shipped within 7 - 12 working days

Brain and behaviour are intrinsically linked. Animals demonstrate a huge and complex repertoire of behaviours, so how can specific behaviours be mapped onto the complicated neural circuits of the brain? Highlighting the extraordinary advances that have been made in the field of behavioural neuroscience over recent decades, this book examines how behaviours can be understood in terms of their neural mechanisms. Each chapter outlines the components of a particular behaviour, discussing laboratory techniques, the key brain structures involved, and the underpinning cellular and molecular mechanisms. Commins covers a range of topics including learning in a simple invertebrate, fear conditioning, taste aversion, sound localization, and echolocation in bats, as well as more complex behaviours, such as language development, spatial navigation and circadian rhythms. Demonstrating key processes through clear, step-by-step explanations and numerous illustrations, this will be valuable reading for students of zoology, animal behaviour, psychology, and neuroscience.

Making Animals Happy - How to Create the Best Life for Pets and Other Animals (Paperback): Temple Grandin, Catherine Johnson Making Animals Happy - How to Create the Best Life for Pets and Other Animals (Paperback)
Temple Grandin, Catherine Johnson 1
R299 R238 Discovery Miles 2 380 Save R61 (20%) Shipped within 7 - 12 working days

In her groundbreaking and bestselling book Animals in Translation, Temple Grandin drew on her own experience with autism as well as her distinguished career as an animal scientist to delivery extraordinary insights into how animals think, act, and feel. Now she builds on those insights to show us how to give our animals the best and happiest life - on their terms, not ours. It's usually easy to pinpoint the cause of physical pain in animals, but to know what is causing them emotional distress is much harder. Drawing on the latest research and her own work, Grandin identifies the core emotional needs of animals. Then she explains how to fulfill them for dogs and cats, horses, farm animals and zoo animals. Whether it's how to make the healthiest environment for the dog that you leave alone in the house during the day, how to how to keep pigs from being bored, or how to know if the lion pacing in the zoo is miserable or just exercising, Grandin teaches us to challenge our assumptions about animal emotions. Making Animals Happy is the culmination of almost 30 years of research, experimentation, and experience. This is essential reading for anyone who's ever owned, cared for, or simply cared about an animal.

Jon Day 1
R395 R323 Discovery Miles 3 230 Save R72 (18%) Shipped within 7 - 11 working days

As a boy, Jon Day was fascinated by pigeons, which he used to rescue from the streets of London. Twenty years later he moved away from the city centre to the suburbs to start a family. But in moving house, he began to lose a sense of what it meant to feel at home. Returning to his childhood obsession with the birds, he built a coop in his garden and joined a local pigeon racing club. Over the next few years, as he made a home with his young family in Leyton, he learned to train and race his pigeons, hoping that they might teach him to feel homed. Having lived closely with humans for tens of thousands of years, pigeons have become powerful symbols of peace and domesticity. But they are also much-maligned, and nowadays most people think of these birds, if they do so at all, as vermin. A book about the overlooked beauty of this species, and about what it means to dwell, Homing delves into the curious world of pigeon fancying, explores the scientific mysteries of animal homing, and traces the cultural, political and philosophical meanings of home. It is a book about the making of home and making for home: a book about why we return.

The Extended Selfish Gene (Hardcover, 4th Revised edition): Richard Dawkins The Extended Selfish Gene (Hardcover, 4th Revised edition)
Richard Dawkins 1
R303 R268 Discovery Miles 2 680 Save R35 (12%) Shipped within 4 - 9 working days

The Selfish Gene is a classic exposition of evolutionary thought. In it Professor Dawkins articulates a gene's eye view of evolution - a view giving centre stage to these persistent units of information, and in which organisms can be seen as vehicles for the replication of genes. The book provoked widespread and heated debate, which in part led Dawkins to write The Extended Phenotype, in which he gave a deeper clarification of the central concept of the gene as the unit of selection, as well as contributing his own development of this insight. For the first time, The Extended Selfish Gene brings these two books together, by including two key chapters from The Extended Phenotype. These chapters provide Dawkins's detailed and powerful response to two issues raised by critics of The Selfish Gene: the accusations of genetic determinism (the idea that our behaviour is entirely determined by our genes), and of "adaptationism " (that all traits are indiscriminately perceived to be adaptations resulting from natural selection). While written in particular for the biology community, Dawkins's clarity of expression allows these chapters to be accessible to all who are seriously engaged with the gene's eye view and its implications. The imaginative, powerful, and stylistically brilliant Selfish Gene not only brought the insights of Neo-Darwinism to a wide audience, but galvanized the biology community, generating much debate and stimulating whole new areas of research. Forty years later, its insights remain as significant as on the day it was published. Along with the two extra chapters, The Extended Selfish Gene includes a new epilogue to The Selfish Gene from the author which highlights the relevance of the gene's eye view to evolutionary biology today.

Sea Turtles of the Atlantic and Gulf Coasts of the United States (Paperback): Carol Ruckdeschel, C. Robert Shoop Sea Turtles of the Atlantic and Gulf Coasts of the United States (Paperback)
Carol Ruckdeschel, C. Robert Shoop; Foreword by James R. Spotila
R462 R367 Discovery Miles 3 670 Save R95 (21%) Shipped within 7 - 11 working days

Written by two of the Southeast's foremost authorities on sea turtle conservation, this is an accessible, fully illustrated guide to the species that frequent the Atlantic and Gulf Coasts of the United States. No one who encounters a sea turtle soon forgets it. The leatherback, for instance, can grow to huge proportions, commonly approaching eight feet in length and more than half a ton in weight. Powerful swimmers, they are also among the deepest divers of all air-breathing sea creatures. Despite these assets, the survival of the leatherback, like that of all sea turtle species, is under constant threat from commercial fishing operations, overdevelopment of nesting grounds, pollution, and predation by introduced species. The guide opens with comprehensive coverage of the sea turtle's evolution, juvenile and adult life cycles, nesting, diet and feeding, disease and parasites, predators, and conservation issues. Each subsequent chapter is dedicated to a particular turtle species: loggerhead, leatherback, Kemp's ridley, green sea turtle, hawksbill, and olive ridley. The account of each species describes distribution, habitats, general appearance, life history and behavior, and conservation. For each species, photographs of hatchlings and adults and a map showing distribution and migration provide further information. Sea turtles have been swimming the seas for one hundred million years. Yet all of the species in this book - indeed, all sea turtles worldwide - are on U.S. and international endangered lists. Biologists Carol Ruckdeschel and C. Robert Shoop have dedicated their careers to learning about sea turtles - and to ensuring that we understand that we are stakeholders in the fate of these ancient creatures. With this guide in hand, readers will be better equipped to understand sea turtle biology and support sea turtle conservation efforts.

Fish Ecology, Evolution, and Exploitation - A New Theoretical Synthesis (Paperback): Ken H. Andersen Fish Ecology, Evolution, and Exploitation - A New Theoretical Synthesis (Paperback)
Ken H. Andersen
R772 R588 Discovery Miles 5 880 Save R184 (24%) Shipped within 7 - 12 working days

Fish are one of the most important global food sources, supplying a significant share of the world (TM)s protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity "insights that classic age-based theory can (TM)t provide "and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

R955 R876 Discovery Miles 8 760 Save R79 (8%) Shipped within 7 - 12 working days

The first comprehensive, interdisciplinary accounting of Nabokov's scientific work, its significance in his artistry, and his contribution to evolutionary theory This landmark book is the first full appraisal of Vladimir Nabokov's long-neglected contributions as a scientist. Although his literary achievements are renowned, until recently his scientific discoveries were ignored or dismissed by many. Nabokov created well over 1,000 technical illustrations of the anatomical structures of butterflies, seeking to understand the evolutionary diversity of small butterflies called Blues. But only lately have scientists confirmed his meticulous research and vindicated his surprising hypotheses. This volume reproduces 154 of Nabokov's drawings, few of which have ever been seen in public, and presents essays by ten leading scientists and Nabokov specialists. The contributors underscore the significance of Nabokov's drawings as scientific documents, evaluate his visionary contributions to evolutionary biology and systematics, and offer insights into his unique artistic perception and creativity.

A wonderfully entertaining celebration of that most unique of creatures: the sloth. In public estimation, sloths have undergone an astonishing transformation in the course of the past few years. Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth. Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'. In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.
