Thousands of ravenous tiny shorebirds race along the water’s edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego.
Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the loss of horseshoe crabs—ancient animals that come ashore but once a year—threatens not only the survival of red knots but also human well-being: the unparalleled ability of horseshoe-crab blood to detect harmful bacteria in vaccines, medical devices, and intravenous drugs safeguards human health. Cramer offers unique insight into how, on an increasingly fragile and congested shore, the lives of red knots, horseshoe crabs, and humans are intertwined. She eloquently portrays the tenacity of small birds and the courage of many people who, bird by bird and beach by beach, keep red knots flying.

Gavin Hardy and Laurence Totelin have brought together their botanical and historical knowledge to produce this unique overview of ancient botany. It examines all the founding texts of botanical science, such as Theophrastus' Enquiry into Plants, Dioscorides' Materia Medica, Pliny the Elder's Natural History, Nicolaus of Damascus' On Plants, and Galen' On Simple Remedies, but also includes lesser known texts ranging from the sixth century BCE to the seventh century CE, as well as some material evidence.
The authors adopt a thematic approach rather than a chronological one, considering important issues such as the definition of a plant, nomenclature, classifications, physiology, the link between plants and their environment, and the numerous usages of plants in the ancient world. The book also takes care to place ancient botany in its historical, social and economic context. The authors have explained all technical botanical terms and ancient history notions, and as a result, this work will appeal to historians of ancient science, medicine and technology; classicists; and botanists interested in the history of their discipline.

Few places have been as influential as the Indian subcontinent in shaping the course of life on Earth. Yet its evolution has remained largely unchronicled. Indica: A Deep Natural History of the Indian Subcontinent fills this gap. From the oldest rocks, formed three billion years ago in Karnataka, to the arrival of our ancestors 50,000 years ago on the banks of the Indus, the author meticulously sifts through wideranging scientific disciplines and through the layers of earth to tell us the story of India, filled with a variety of fierce reptiles, fantastic dinosaurs, gargantuan mammals and amazing plants.
Beautifully produced in full colour, with a rare collection of images, illustrations and maps, Indica is full of fascinating, lesser-known facts. It shows us how every piece of rock and inch of soil is a virtual museum, and how, over billions of years, millions of spectacular creatures have reproduced, walked and lived over and under it.
