In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    This friendly guide answers all your questions, from setting up your tank and selecting fish to the water, chemicals, plants, and much more. There's also expanded guidance on combining different species of fish, maintaining a tank, cleaning gravel, and dealing with common problems such as algae. Discover how to * Choose the right aquarium * Select the best fish * Get good deals on equipment * Maintain a clean, healthy environment * Handle tank pitfalls * Breed your fish

    Each species is covered in detail with information on how to identify, whether from a leaf, twig, bark or whole tree, plus extra information on where the tree grows (including a map), how high they grow, what uses the tree is used for and its unique history.Every species is also comprehensively illustrated with photographs of every useful feature – bark, leaf, seed, flower, twig and whole tree.Sample identification section:Silver Birch Betula pendula (Betulaceae) height to 26mA slender, fast-growing deciduous tree with a narrow, tapering crown when young and growing vigorously. Older trees acquire a weeping habit, especially if growing in an open, uncrowded situation.

    Marc Bekoff, one of the world’s leading animal experts and activists, here applies rewilding to human attitudes. Rewilding Our Hearts invites readers to do the essential work of becoming reenchanted with the world, acting from the inside out, and dissolving false boundaries to truly connect with both nature and themselves.

    What exactly is the meaning of all those stone walls in the middle of the forest? Why do beech and birch trees have smooth bark when the bark of all other northern species is rough? How do you tell the age of a beaver pond and determine if beavers still live there? Why are pine trees dominant in one patch of forest and maples in another? What happened to the American chestnut? Turn to this book for the answers, and no walk in the woods will ever be the same.

    It floats like a jewel in the inky black void. The reflection of the suns light from the vast expanse of water covering its surface creates its gem-like blue colour. In the entire solar system Earth is the only planet that has water in its liquid form in such quantities. Scientists have calculated that 70% of our planet is covered by water; small wonder then that humans have always been so fascinated by the oceans and what lies beneath. Today while we still have so much more of the ocean realm to uncover we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life. The Blue Planet leads us on a voyage of exploration from the coasts, the very edges of the oceans, to the deep where weird and monstrous fish lurk in a world of perpetual darkness. Along the way we meet a host of wonderful creatures from tiny copepods to majestic blue whales, from the grotesque hairy anglerfish, to the amazing tripod fish that stands on 3 delicate legs waiting to snap up unsuspecting prey. With a foreword by David Attenborough and 400 colour photos The Blue Planet is the first complete and comprehensive portrait of the whole ocean system.

    Get ready to unthink what you thought you knew and journey into the deep, dark depths of the Jurassic.The discovery of the first feathered dinosaur in China in 1996 sent shockwaves through the palaeontological world. Were the feathers part of a complex mating ritual, or a stepping stone in the evolution of flight? And just how closely related is T. rex to a chicken? Award-winning journalist John Pickrell reveals how dinosaurs developed flight and became the birds in our backyards. He delves into the latest discoveries in China, the US, Europe and uncovers a thriving black market in fossils and infighting between dinosaur hunters, plus the controversial plan to use a chicken to bring dinosaurs back from the dead.

    Her twenty- five-year career conducting experiments that involve rats has led her to a surprising conclusion: Through their adaptive strategies and good habits, these unassuming little animals can teach us some essential lessons about how we, as humans, can lead successful lives. From emotional resilience and a strong work ethic to effective parenting and staying healthy, the lab rat is an unlikely but powerful role model for us all. This is a surprising and engaging guided tour into the sophisticated mental, emotional, and behavioral worlds of these frequently maligned and often misunderstood little creatures.

    From birds to baboons, insects to iguanas, animals feel good thanks to play, sex, touch, food, anticipation, comfort, aesthetics, and more. Combining rigorous evidence, elegant argument and amusing anecdotes, leading animal behavior researcher Jonathan Balcombe shows that the possibility of positive feelings in creatures other than humans has important ethical ramifications for both science and society.

    Their numbers are in freefall, dropping by nearly 70 percent in the last sixty years, a billion fewer now than in 1950. Extinction stalks the ocean, and there is a danger that the hundred-million-year-old cries of a seabird colony, rolling around in the bays and headlands of high latitudes, will this century become but a memory.

    It stars turtles and shady and heroic human characters both, in settings ranging from luxury redoubts to degraded habitats, during a time when the confluence of easy global trade, limited supply, and inexhaustible demand has accelerated the stress on species. The growth of the middle class in high-population regions like China, where the turtle is particularly valued, feeds this perfect storm into which the turtle finds itself lashed. This is a tale not just of endangered turtles but also one of overall human failings, frailties, and vulnerabilities—all punctuated by optimistic hope for change fueled by dedicated turtle champions.

    Experienced birders use the most easily observed characteristics — size, structure, behavior, and general color patterns — to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

    Collects photographs, range maps, and descriptive entries identifying the markings, habits, habitat, and voice of each species.
