Описание: In this book, the authors present topical research in the study of the identification, uses and conservation of wild plants. Topics discussed include identification of plant species using traditional and molecular-based methods; extracts from wild plants that possess antioxidant capacity; wild plant seed identification through image and linear discriminant analysis; the keystone tree species of Fagus sylvatica in the glacial refuge area of southern Europe and how dominant plant species influence the patterns of ecological interactions.

Описание: In 1952, at age sixteen, Sylvia Earle - then a budding marine biologist - borrowed a friend's copper diving helmet, compressor, and pump and slipped below the waters of a Florida river. It was her first underwater dive. Since then, Earle has descended to more than 3,000 feet in a submersible and, despite beginning at a time when few women were taken seriously as marine scientists, has led or participated in expeditions totaling more than 7,000 hours underwater, and counting.  

Equal parts memoir, adventure tale, and call to action, Sea Change: A Message of the Oceans has become a classic of environmental literature, at once the gripping adventure story of Earle's three decades of undersea exploration, an insider's introduction to the dynamic field of marine biology, and an urgent plea for the preservation of the world's fragile and rapidly deteriorating ocean ecosystems.

Featuring a gallery of color photographs and a new preface by Earle, this new edition of Sea Change arrives at a uniquely pivotal time when its message is needed more than ever before. She writes, 'I want to share the exhilaration of discovery, and convey a sense of urgency about the need for all of us to use whatever talents and resources we have to continue to explore and understand the nature of this extraordinary ocean planet.' Her message is clear: how we treat the oceans now will determine the future health of the planet - and our species.

Описание: Fish and seafood are widely available foods that provide important nutrients to consumers. Research conducted over the past few years suggests that there are health benefits associated with fish and seafood consumption, including for the cardiovascular and visual systems. It was also reported that such a diet increases protection in infants against arthritis or cancer. Although regular seafood consumption has been linked to health benefits for the general population, contaminants that may be present in seafood could pose a risk to humans. There are a number of contaminants that may be associated with seafood, including chemicals, metals, toxins and other substances as well as potentially harmful microbes. Most seafood contains detectable levels of contaminants because these are a part of the environment and food chain. This book discusses shellfish in more detail, including the purification process of bivalve shellfish; shellfish toxins; phycotoxins and heavy metals in shellfish; and shellfish sensitivity.
