    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.

    A. Bradshaw explores the minds, emotions, and lives of elephants. Wars, starvation, mass culls, poaching, and habitat loss have reduced elephant numbers from more than ten million to a few hundred thousand, leaving orphans bereft of the elders who would normally mentor them.As a consequence, traumatized elephants have become aggressive against people, other animals, and even one another; their behavior is comparable to that of humans who have experienced genocide, other types of violence, and social collapse. By exploring the elephant mind and experience in the wild and in captivity, Bradshaw bears witness to the breakdown of ancient elephant cultures.All is not lost. People are working to save elephants by rescuing orphaned infants and rehabilitating adult zoo and circus elephants, using the same principles psychologists apply in treating humans who have survived trauma. Bradshaw urges us to support these and other models of elephant recovery and to solve pressing social and environmental crises affecting all animals, human or not.

    A spider lassoes its prey. A beetle persuades a bee to care for its young. This beautifully illustrated book by veteran naturalist Sir David Attenborough offers a rare glimpse into the secret life of invertebrates, the world's tiniest--and most fascinating--creatures.Small by virtue of their lack of backbones, this group of living things plays a surprisingly large role in the evolutionary cycle. These diverse creatures (more than one million species are believed to exist) roamed the earth before us and will still be here when we have gone. They are the pollinators, cleaners, and recyclers of life on earth. Without them, we would not last long.Attenborough has studied and enjoyed these diminutive beings since he was a schoolboy in the Leicestershire countryside of England. Life in the Undergrowth, part of his innovative series on natural history topics, looks at invertebrates the world over: their arrival on land and mastery of every habitat, and their fantastic variety of hunting, mating, and highly organized social behaviors.Adults are prejudiced against insects--handicapped by their ignorance and fears and limited by their size and vision. Children, who are closer to insects in size, notice and enjoy the tiny creatures.In this companion book to the Animal Planet television program, Attenborough shares his childlike curiosity for invertebrates, taking us down wormholes and into insect homes for an up-close-and-personal look at their habitats. As the biblical book of Proverbs implores: Go to the ant, thou sluggard: consider her ways and be wise. David Attenborough does go. It is worth going with him.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.
