    Birds were rarely used in similar studies on the grounds that they were merely talented mimics--that they were, after all, "birdbrains." Experiments performed primarily on pigeons in Skinner boxes demonstrated capacities inferior to those of mammals; these results were thought to reflect the capacities of all birds, despite evidence suggesting that species such as jays, crows, and parrots might be capable of more impressive cognitive feats.Twenty years ago Irene Pepperberg set out to discover whether the results of the pigeon studies necessarily meant that other birds--particularly the large-brained, highly social parrots--were incapable of mastering complex cognitive concepts and the rudiments of referential speech. Her investigation and the bird at its center--a male Grey parrot named Alex--have since become almost as well known as their primate equivalents and no less a subject of fierce debate in the field of animal cognition. This book represents the long-awaited synthesis of the studies constituting one of the landmark experiments in modern comparative psychology.

    Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea—including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience—Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.

    During the day, she worked with toddlers with significant delays in language development and used Augmentative and Alternative Communication (AAC) devices to help them communicate. At night, she wondered: If dogs can understand words we say to them, shouldn't they be able to say words to us? Can dogs use AAC to communicate with humans?Christina decided to put her theory to the test with Stella and started using a paw-sized button programmed with her voice to say the word "outside" when clicked, whenever she took Stella out of the house. A few years later, Stella now has a bank of more than thirty word buttons, and uses them daily either individually or together to create near-complete sentences.How Stella Learned to Talk is part memoir and part how-to guide. It chronicles the journey Christina and Stella have taken together, from the day they met, to the day Stella "spoke" her first word, and the other breakthroughs they've had since. It also reveals the techniques Christina used to teach Stella, broken down into simple stages and actionable steps any dog owner can use to start communicating with their pets.Filled with conversations that Stella and Christina have had, as well as the attention to developmental detail that only a speech-language pathologist could know, How Stella Learned to Talk will be the indispensable dog book for the new decade.

    . . . This is an exciting book. Although Schaller feels that this is 'not an adventure book,' few readers will be able to agree."—Irven DeVore, Science

    But in a world full of poisons, there was also an urgent practical need to name and recognize different plants, because most medicines were made from plant extracts.Anna Pavord takes us on a thrilling adventure into botanical history, traveling from Athens in the third century BC, through Constantinople, Venice, the medical school at Salerno to the universities of Pisa and Padua. The journey, traced here for the first time, involves the culture of Islam, the first expeditions to the Indies and the first settlers in the New World.In Athens, Aristotle's pupil Theophrastus was the first man ever to write a book about plants. How can we name, sort, and order them? He asked. The debate continues still, two thousand years later. Sumptuously illustrated in full colour, The Naming of Names gives a compelling insight into a world full of intrigue and intensely competitive egos.

    . . Patterson's book must now be considered the definitive Tsavo lion study... one of the world's leading experts on lions as well as an important conservationist.--Publishers WeeklyThrough field research and forensic evidence, a scientist reveals his theory on why two Kenyan lions killed humans and then ate their preyIn March 1898, the British began building a bridge over the Tsavo River in East Africa. In nine months, two male lions killed and ate nearly 135 workers, halting construction.After a long hunt Colonel J. H. Patterson killed the lions, which are now on display at the Field Museum of Natural History in Chicago.As codirector of the Tsavo Research Project, Bruce Patterson has conducted extensive fieldwork throughout the region on these lions. In The Lions of Tsavo, Patterson retells the harrowing story of those bloody nights in Kenya. He presents new forensic evidence on these maneless lions and argues that the man-eating behavior exhibited in 1898 came from the encroachment of human populations on wild habitats.Patterson continues this theory by exploring man's interaction with the changing Kenyan environment, creating a complete, up-to-date, and scientific look behind this intriguing murder mystery.

    A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality.Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.
