DOWNLOAD EBOOKAn authoritative treatise on the history of botanical studies and exploration in Angola. For any region, cataloging, interpreting, and understanding the history of botanical exploration and plant collecting, and the preserved specimens that were amassed as a result, are critically important for research and conservation. In this book, published in cooperation with the International Association for Plant Taxonomy, Estrela Figueiredo and Gideon F. Smith, both botanists with expertise in the taxonomy of African plants, provide the first comprehensive, contextualized account of plant collecting in Angola, a large country in south-tropical Africa. An essential book for anyone concerned with the biodiversity and history of Africa, this authoritative work offers insights into the lives, times, and endeavors of 358 collectors. In addition, the authors present analyses of the records that accompanied the collectors’ preserved specimens. Illustrated in color throughout, the book fills a large gap in the current knowledge of the botanical and exploration history of Africa.

DOWNLOAD EBOOKHow herbaria illuminate the past and future of plant science Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time—including changes related to climate. Maura C. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the growth of herbaria during the Age of Exploration, the development of classification systems to organize the collections, and herbaria’s indispensable role in the tracking of climate change and molecular evolution. Herbaria also have historical, aesthetic, cultural, and ethnobotanical value—these preserved plants can be linked to the Indigenous peoples who used them, the collectors who sought them out, and the scientists who studied them. This book testifies to the central role of herbaria in the history of plant study and to their continued value, not only to biologists but to entirely new users as well: gardeners, artists, students, and citizen-scientists.

DOWNLOAD EBOOKThe world is on the verge of receiving new life forms that will profoundly and irrevocably change the global economy: the "gene hunters" who first cloned the gene in 1973 are now not only modifying existing species but also creating new plants and animals. Ready or not for such awesome power, the human race has put itself in a position to govern evolution. What will we do with the abilities we now command? asks this broad and stimulating book on the role of plant material in economic development. Writing in a style that is easily understandable even to those with no background in biotechnology, Calestous Juma begins by showing how the importation of plants strengthened the British Empire and brought the United States to global agricultural superiority. He goes on to explore the current international competition for genetic material and the potential impact of biotechnology on the relationship of the developed and developing world. Juma points out that biotechnology poses real dangers to the third world. Often one of the few exportable resources that a developing country possesses is an unusual or rare crop, but biotechnological techniques make possible the cultivation of many such crops outside their natural habitats, potentially eliminating the need to import the crops from the countries in which they grow indigenously. After discussing the threat of biotechnology, Juma comes full circle and points out that it does not have to be a threat. Actually, tremendous benefits could accrue to the third world from biotechnology--if and only if that new technology is adapted to its needs. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

DOWNLOAD EBOOKEast Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.
