Why Fish Don'T Exist (Paperback): Lulu Miller Why Fish Don'T Exist (Paperback)
Lulu Miller
R467 R350 Discovery Miles 3 500 Save R117 (25%) Ships in 10 - 15 working days

A Best Book of 2020: The Washington Post * NPR * Chicago Tribune * Smithsonian A "remarkable" (Los Angeles Times), "seductive" (The Wall Street Journal) debut from the new cohost of Radiolab, Why Fish Don't Exist is a dark and astonishing tale of love, chaos, scientific obsession, and--possibly--even murder. "At one point, Miller dives into the ocean into a school of fish...comes up for air, and realizes she's in love. That's how I felt: Her book took me to strange depths I never imagined, and I was smitten." --The New York Times Book Review David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. But the more of the hidden blueprint of life he uncovered, the harder the universe seemed to try to thwart him. His specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake--which sent more than a thousand discoveries, housed in fragile glass jars, plummeting to the floor. In an instant, his life's work was shattered. Many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation that he believed would at last protect his work against the chaos of the world. When NPR reporter Lulu Miller first heard this anecdote in passing, she took Jordan for a fool--a cautionary tale in hubris, or denial. But as her own life slowly unraveled, she began to wonder about him. Perhaps instead he was a model for how to go on when all seemed lost. What she would unearth about his life would transform her understanding of history, morality, and the world beneath her feet. Part biography, part memoir, part scientific adventure, Why Fish Don't Exist is a wondrous fable about how to persevere in a world where chaos will always prevail.

Deep Time - Cladistics, the Revolution in Evolution (Paperback): Henry Gee Deep Time - Cladistics, the Revolution in Evolution (Paperback)
Henry Gee
R251 Discovery Miles 2 510 Ships in 12 - 17 working days

In Deep Time, Henry Gee, assistant editor of Nature, shows us that everything we think we know about evolution is wrong. For a long time, popular scientists have told us that by looking at a fossilised bone we could tell whether it belonged to our ancestors or not. This is not true. In Deep Time, Henry Gee, introduces for the first time in the popular science market a new way of thinking that has revolutionised the way that scientists are approaching the past - Cladistics. Cladistics ignores story-telling and authority and proposes a method based on shared characteristics, rather than ancestry and descent. As a result of using this new method Henry Gee is able to show us the wealth of new ideas that is radically altering our notions of the past: Dinosaurs with feathers; why fish developed fingers; what it means to be human.

Freeliving Freshwater Protozoa (Paperback, New Ed): David J. Patterson, Stuart Hedley Freeliving Freshwater Protozoa (Paperback, New Ed)
David J. Patterson, Stuart Hedley

Gerard Gorman
R797 Discovery Miles 7 970 Ships in 12 - 17 working days

This book considers the natural history and cultural symbolism of a most unusual woodpecker - a species that neither excavates nest holes in trees, nor bores into wood to find insect prey. The Wryneck is best renowned for performing a twisting, writhing head and neck display when threatened, but this ground-breaking work reveals many more secrets of its behaviour and evolution. Detailed information is presented on the species' origins, taxonomy, anatomy, appearance, moult, calls, distribution, conservation status, habitats, movements, breeding, diet and relationships, along with a chapter on its closest relative, the Red-throated Wryneck. The text is richly illustrated throughout with high quality photographs as well as sound spectrograms. The author augments his many hours watching Wrynecks with comprehensive literature research, creating what is surely the definitive volume on the species. This all-encompassing and engaging account has been written for a wide audience, whether professional ornithologist, citizen scientist, amateur birder, woodpecker aficionado or simply someone who wishes to learn more about this curious and remarkable bird.

Do Species Exist? - Principles of Taxonomic Classification (Hardcover): W. Kunz Do Species Exist? - Principles of Taxonomic Classification (Hardcover)

The species problem (the two questions, do species exist and, if yes, according to what criteria do two individuals belong to the same species) is one of the oldest questions in biology. Darwin's Origin of the Species' was - and still is - one of the most comprehensive answers to this problem. However, even Darwin's work cannot satisfactorily explain many of the speciation questions. Over the years, many concurrent taxonomic systems have evolved each of them particularly well suited for the speciation of certain groups of organisms but all of them fail to provide a universal answer to all questions relating to speciation. "Do Species Exist?" is a readily comprehensible guide for a wide audience of biologists, field taxonomists and philosophers, giving an excellent overview of the species problem without delving into the many feuds between the different schools of taxonomy. Written by a geneticist with extensive experience in field taxonomy, this practical book provides the sound scientific background to the problems arising with classifying organisms according to species. It covers the main current theories of specification and gives a number of examples that cannot be explained by any single theory alone.

Positive Evolutionary Psychology - Darwin's Guide to Living a Richer Life (Paperback): Glenn Geher, Nicole Wedberg Positive Evolutionary Psychology - Darwin's Guide to Living a Richer Life (Paperback)
Glenn Geher, Nicole Wedberg
R1,430 Discovery Miles 14 300 Ships in 10 - 15 working days

Positive psychologists focus on ways that we can advance the lives of individuals and communities by studying the factors that increase positive outcomes such as life satisfaction and happiness. Evolutionary psychologists use the principles of evolution, based on Darwin's understanding of life, to help shed light on any and all kinds of psychological phenomena. This book brings together both fields to explore positive evolutionary psychology: the use of evolutionary psychology principles to help people and communities experience more positive and fulfilling lives. Across eleven chapters, this book describes the basic ideas of both evolutionary and positive psychology, elaborates on the integration of these two fields as a way to help advance the human condition, discusses several domains of human functioning from the perspective of positive evolutionary psychology, and finally, looks with an eye toward the future of work in this emerging and dynamic field. Over the past few decades, evolutionary psychologists have begun to crack the code on such phenomena as happiness, gratitude, resilience, community, and love. This book describes these facets of the human experience in terms of their evolutionary origins and proposes how we might guide people to optimally experience such positive phenomena in their everyday lives.

Cryptic Species - Morphological Stasis, Circumscription, and Hidden Diversity (Hardcover): Alexandre K. Monro, Simon J. Mayo Cryptic Species - Morphological Stasis, Circumscription, and Hidden Diversity (Hardcover)
Alexandre K. Monro, Simon J. Mayo
R2,135 Discovery Miles 21 350 Ships in 12 - 17 working days

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

Phylogenetic Systematics - Haeckel to Hennig (Paperback): Olivier Rieppel Phylogenetic Systematics - Haeckel to Hennig (Paperback)
Olivier Rieppel
R1,885 Discovery Miles 18 850 Ships in 12 - 17 working days

Phylogenetic Systematics: Haeckel to Hennig traces the development of phylogenetic systematics against the foil of idealistic morphology through 100 years of German biology. It starts with the iconic Ernst Haeckel-the German Darwin from Jena-and the evolutionary morphology he developed. It ends with Willi Hennig, the founder of modern phylogenetic systematics. Written in English, the book presents a unique perspective on a vast body of German biological literature. The book also offers a perspective on German biology in the Third Reich. The author looks at how idealistic morphology and phylogenetic systematics represented two antagonistic traditions in German biology, the first organicist-holistic, the latter empiricist-positivistic. In addition, he explains the ways in which both traditions acquired socio-political and ideological connotations, culminating in their accommodation to different strands of Nazi ideology. The book's nine chapters summarize a century of the conceptual development of systematics, describe both the history and philosophy of phylogenetic approaches to the understanding of the history of life, examine the role of important people such as Haeckel, Gegenbauer, Portman, von Bertalanffy, Stresemann, and Hennig, and critically evaluate the impact and influence of Nazism on evolutionary biology. Chapter titles include: The Evolutionary Turn in Comparative Anatomy; Of Parts and Wholes; The Turn against Haeckel; The Rise of Holism in German Biology; The Rise of German ("Aryan") Biology; Ganzheitsbiologie; The Ideological Instrumentalization of Biology; A New Beginning: From Speciation to Phylogenetics; and Grundzuge: The Conceptual Foundations of Phylogenetic Systematics.

Systema Naturae 250 - The Linnaean Ark (Paperback): Andrew Polaszek Systema Naturae 250 - The Linnaean Ark (Paperback)
Andrew Polaszek
R1,959 Discovery Miles 19 590 Ships in 12 - 17 working days

The advent of relational databasing and data storage capacity, coupled with revolutionary advances in molecular sequencing technology and specimen imaging, have led to a taxonomic renaissance. Systema Naturae 250 - The Linnaean Ark maps the origins of this renaissance, beginning with Linnaeus, through his "apostles", via the great unsung hero Charles Davies Sherbon - arguably the father of biodiversity informatics - up to the present day with the Planetary Biodiversity Inventories and into the future with the Encyclopedia of Life and web-based taxonomy. The book provides scientific, historical, and cultural documentation of the evolution of taxonomy and the successful adaptation of the Linnaean nomenclature system to that evolution. It underscores the importance of taxonomic accuracy, not only for the classification of living organisms, but for a more complete understanding of the living world and its biodiversity. The book also examines the role of technologies such as DNA sequencing, specimen imaging, and electronic data storage. A celebration of 250 years of the scientific naming of animals, Systema Naturae 250 - The Linnaean Ark records and explores the history of zoological nomenclature and taxonomy, detailing current and future activity in these fields. Descriptive taxonomy has been in decline, despite the fact that the classification of organisms through taxonomic studies provides the foundation of our understanding of life forms. Packed with illustrations and tables, this book establishes a vision for the future of descriptive taxonomy and marks the beginning of a period of rapid growth of taxonomic knowledge.

Graham Bell
R1,387 Discovery Miles 13 870 Ships in 10 - 15 working days

The deep sea covers more than half the surface of the Earth, but until the circumnavigation made by the HMS Challenger almost nothing was known about the animals that live there. Full Fathom 5000 gives an account of the remarkable discoveries that were made during the voyage and describes the strange and bizarre creatures that live in perpetual darkness a kilometer or more below the surface of the sea. Until the early 1870s, very little was known about the creatures lurking in the depths of our oceans. People had found a few things trapped in fishing gear or caught on the anchors of ships, but those who tried to venture to the bottom of the seafloor often died before they made it there. The first systematic investigation into life in our oceans was made during the circumnavigation of the HMS Challenger. Scientists credit this voyage as the beginning of modern oceanography, and the story of it is full of twists and turns. It led to the discovery of a whole new fauna previously unknown, which Full Fathom 5000 describes for the first time in one place for readers. In this book, Graham Bell takes readers through the voyage station by station, following the progress of the expedition and introducing some of the new and strange animals that were hauled up from the depths of the ocean and seen by human eyes for the first time. You will meet, among others, the ugliest fish in the world, flesh-eating clams, dwarf males, sea devils, and an octopus that wears lipstick. The book begins with a description of the first attempts scientists made to explore the deep sea, leading up to the plan for a voyage around the world on the HMS Challenger. The chapters take readers from station to station, though all of the world's oceans, visiting every continent and crossing the Equator five times. Bell details what was discovered during hundreds of stops to take samples, and he describes around a hundred stations where remarkable animals were hauled from the sea. The book ends with a description of what came after the end of this journey, explaining what they did with the animals that were collected and what became of the scientists and sailors who planned the voyage and traveled together around the world.

Unnatural Selection (Hardcover): Katrina Van Grouw Unnatural Selection (Hardcover)
Katrina Van Grouw
R1,094 Discovery Miles 10 940 Ships in 12 - 17 working days

A lavishly illustrated look at how evolution plays out in selective breeding Unnatural Selection is a stunningly illustrated book about selective breeding-the ongoing transformation of animals at the hand of man. More important, it's a book about selective breeding on a far, far grander scale-a scale that encompasses all life on Earth. We'd call it evolution. A unique fusion of art, science, and history, this book is intended as a tribute to what Charles Darwin might have achieved had he possessed that elusive missing piece to the evolutionary puzzle-the knowledge of how individual traits are passed from one generation to the next. With the benefit of a century and a half of hindsight, Katrina van Grouw explains evolution by building on the analogy that Darwin himself used-comparing the selective breeding process with natural selection in the wild, and, like Darwin, featuring a multitude of fascinating examples. This is more than just a book about pets and livestock, however. The revelation of Unnatural Selection is that identical traits can occur in all animals, wild and domesticated, and both are governed by the same evolutionary principles. As van Grouw shows, animals are plastic things, constantly changing. In wild animals, the changes are usually too slow to see-species appear to stay the same. When it comes to domesticated animals, however, change happens fast, making them the perfect model of evolution in action. Featuring more than four hundred breathtaking illustrations of living animals, skeletons, and historical specimens, Unnatural Selection will be enjoyed by anyone with an interest in natural history and the history of evolutionary thinking.

This is an essential reference for describing, measuring and classifying the foliage of flowering plants. The presented system provides long-needed guidelines for characterizing the organization, shape, venation, and surface features of angiosperm leaves. In contrast to systems focusing on reproductive characters for identification, the emphasis is on macroscopic features of the leaf blade including leaf characters, venation, and tooth characters. The advantage of this system is that it allows for the classification of plants independently of their flowers, which is especially useful for fossil leaves (usually found in isolation) and tropical plants (whose flowering cycles are brief and irregular, and whose fruits and flowers may be difficult to access). An illustrated terminology including detailed definitions and annotated illustrations is the focus of the classification system, the aim of which is to provide a framework with comparative examples to allow both modern and fossil leaves to be described and classified consistently.

Quentin D. Wheeler
R3,400 Discovery Miles 34 000 Ships in 12 - 17 working days

Finalist for 2009 The Council on Botanical & Horticultural Libraries Literature Award! A Fresh Look at Taxonomy The most fundamental of all biological sciences, taxonomy underpins any long term strategies for reconstructing the great tree of life or salvaging as much biodiversity as possible. Yet we are still unable to say with any certainty how many species are living on the earth. The New Taxonomy describes how a confluence of theory, cyberinfrastructure, and international teamwork can meet this unprecedented research challenge and marks an emerging field, cybertaxonomy. Taxonomy Meets the Challenges of the Biodiversity Crisis An in-depth discussion of the future of descriptive taxonomy, the book examines the efforts of several international groups to catalog the world's biodiversity and make it accessible. An answer to Julien Huxley's The New Systematics, the book marks the beginning of an upward trajectory of taxonomy to meet the unprecedented challenges of the biodiversity crisis. Contemporary taxonomists reclaim the unique mission, goals, and importance of taxonomy as an independent science. They cover technologies such as DNA evidence and its applications, computer-assisted species identification, digital morphology, and E-typification. The book also provides insight into effective ways of organizing taxonomic information and discusses what benefits can be leveraged from a rapid growth of taxonomic knowledge. A Vision and A Strategy for the Future Not much has changed since E.O. Wilson pointed out how little we know of Earth's species in 1985. This book offers a vision and a strategy for changing all that. The first current, unapologetic look at morphology and descriptive taxonomy that points out their incredible importance to science and society, this book frames one of the most constructive responses to biodiversity crises. It is a call to action for the taxonomy and museum communities to come together and to organize, plan, innovate, and initiate the most ambitious period of exploration in the long history of taxonomy.

Classification and Biology (Paperback, New Ed): R.A. Crowson Classification and Biology (Paperback, New Ed)
R.A. Crowson
R1,429 Discovery Miles 14 290 Ships in 12 - 17 working days

Classification of plants and animals is of basic interest to biologists in all fields because correct formulation and generalization are based on sound taxonomy. This book by a world authority relates traditional taxonomic studies to recent developments in biochemical and other fields. It provides guidelines for the integration of modern and traditional methods and explains the underlying principles and philosophy of systematics. The problems of zoological, botanical, and paleontological classification are dealt with in great detail and microbial systematics briefly. Science may be defined as the rational and objective study of the external universe by human beings. Whether the study of man himself is included, as part of science will depend on how we interpret 'human beings' in this definition. If we regard humanity as in essence an assemblage of isolated individuals, then anyone of them may regard the rest as part of the external universe and thus as 'material' for scientific study; on the other hand, if, humanity is regarded as essentially one body and science as a collective rather than an individual function, we can hardly avoid maintaining in some form or other the traditional distinction between the sciences and the humanities. The problems of classifying human beings will not be considered in detail in this book, though it will appear that if the criteria developed for other animals were applied to our own case, the chimpanzee, the gorilla and perhaps the orangutan would join us in the genus Homo. This book deals with questions that are of direct relevance to the work of all biologists as well as of all specialists in taxonomy. In addition, the clarity of the author's exposition and his felicitous style make it challenging reading for all undergraduate and graduate students in the biological sciences. R.A. Crowson (1914-1999) was lecturer in Zoological Taxonomy at the University of Glasgow. His Antipodean expedition to Australia and New Zealand was made possible by the Leverhume research fellowship, and he was able to explore America when the Museum of Comparative Zoology at Harvard University appointed him to the Alexander Agassiz visiting lectureship in 1969. The 1968 Congress of Entomology in Moscow enabled him to meet many Russian scientists with whom he had corresponded for several years. His wide-ranging interests and travels allowed Dr. Crowson to bring a truly international outlook to bear upon his subject.
