Plants form a fundamental element of the biosphere, and the evolution of plants has directly affected the evolution of animal life and the evolution of the Earth's climate. Plants have also become essential to humans not only in the form of cereal crops, fruit, and vegetables, but in their many other uses in wood and paper, and in providing medicines. Their aesthetic importance too in our parks and gardens as well as in wildflower meadows and great forests should not be underestimated. In this Very Short Introduction Timothy Walker, Director of the Botanical Gardens in Oxford, provides a concise account of the nature of plants, their variety, their evolution, and their importance and uses, stressing the need and efforts for their conservation for future generations. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Wilfred Burchett went to Lisbon in 1974 to cover the military overthrow of the fascist dictatorship that had ruled the country for nearly five decades. Burchett's on-the-ground reporting details the immediate aftermath of the coup and the civilian uprising that followed, which took its name, the Carnation Revolution, from the flowers demonstrators handed out to soldiers and placed in their rifle muzzles. The people's victory began a transition to democracy. It prompted the withdrawal of troops from Portugal's colonies, bringing independence to Guinea Bissau and soon to Angola, Mozambique and other colonial territories.On the fiftieth anniversary of the revolution's end, The Captains' Coup offers an insightful, poignant narrative never before available in English from a journalist of international repute. The text is based on the author's original typescripts, discovered recently in the National Library of Australia.Included are a foreword and introductory essay that explore the political and journalistic significance of Burchett's work. Illustrated by contemporary photographs and political posters, the volume is complemented by the editors' annotations, providing essential historical context.Also included is an afterword by historian and filmmaker Tariq Ali.

An enticing illustrated look at pollination, one of the most astonishing marvels of the natural worldPollination is essential to the survival of most plants on Earth. Some plants rely on the wind to transport pollen from one flower to another. Others employ an array of ingenious strategies to attract and exploit pollinators, whether they be insects, birds, or mammals. This beautifully illustrated book provides an unprecedented look at the wonders of pollination biology, drawing on the latest science to explain the extraordinarily complex relationship between plant and pollinator, and revealing why pollination is vital for healthy ecosystems and a healthy planet.Timothy Walker offers an engaging introduction to pollination biology and explores the many different tactics of plant reproduction. He shows how wind and water can be effective yet wildly unpredictable means of pollination, and describes the intimate interactions of pollinating plants with bees and butterflies, beetles and birds, and lizards and bats. Walker explores how plants entice pollinators using scents, colors, and shapes, and how plants rely on rewards as well as trickery to attract animals. He sheds light on the important role of pollination in ecology, evolution, and agriculture, and discusses why habitat management, species recovery programs, and other conservation efforts are more critical now than ever.Featuring hundreds of color photos and illustrations, Pollination is suitable for undergraduate study and is an essential resource for naturalists, horticulturalists, and backyard gardeners.
