    Featuring more than 500 full-color illustrations and photographs, along with detailed annotations, Dorling Kindersley Handbooks make identification easy and accurate.

    Bugs, of all kinds, were considered to be “born of mud” and to be “beasts of the devil.”  Why would anyone, let alone a girl, want to study and observe them? One of the first naturalists to observe live insects directly, Maria Sibylla Merian was also one of the first to document the metamorphosis of the butterfly. In this nonfiction biography, illustrated throughout with full-color original paintings by Merian herself, author Joyce Sidman paints her own picture of one of the first female entomologists and a woman who flouted convention in the pursuit of knowledge and her passion for insects.

    He began his career making films for the TV series "Survival," which started wildlife film-making as we know it, and is responsible for numerous groundbreaking documentaries and natural history discoveries -- from being the first person to film hippos and crocodiles underwater and the wildebeest migrating to observing that hyenas hunt. His friends and colleagues have included George and Joy Adamson and David Attenborough; he showed Dian Fossey her first mountain gorilla. His wife and long-term collaborator was Joan Root, who was tragically murdered in 2006 in retaliation for her environmental campaigning in Kenya. In "Ivory, Apes & Peacocks," Alan tells the story of his life's work, from his arrival in Kenya as a young boy (furious at having to leave behind Britain's birds) to his game-changing films, which looked at whole ecosystems (baobab trees, termite mounds) rather than the Big Five animals. Along the way we encounter Sally the pet hippo and Emily the house-proud chimp as well leopard and snake bites, ballooning adventures and amphibious cars. In this extraordinary memoir we look at Africa's wonders through the eyes of a visionary, live through hair-raising adventure and personal tragedy and also bear witness to a natural world now largely lost from view.

    In the present volume, the author's goal of introducing children to the fascinating subject of bird life is brilliantly realized in story fashion. While "interviewing" Slaty the Junco, Redwing the Blackbird, Melody the Wood Thrush, Spooky the Screech Owl, and dozens of other common birds, our guides, Peter Rabbit and saucy Jenny Wren — and, of course, the reader — learn about their physical appearances, eating and nesting habits, and songs and calls. Over eighty years after its first publication, the book remains noteworthy and valuable for its extraordinarily successful blend of information and entertainment.

    

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    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.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    Few people know bears as intimately as Else Poulsen. She has raised bears, comforted bears, taught bears, learned from bears, had bears communicate their needs to her, and nursed bears back to health. This remarkable book reveals the many insights about bears and their lives that she has gained through her work with them. In the eighties, Poulsen became a zookeeper in Calgary, where she rehabilitated bears in crisis. She has shared in the joy of a polar bear discovering soil under her paws for the first time in twenty years, felt the pride of a cub learning to crack nuts with her molars, and grieved at the horror of captivity for Asian black bears in China.Smiling Bears provides an enlightening and moving portrait of bears in all their richness and complexity and of Poulsen's exhilarating work with them. Also available in paperback.
