Book Description
For over a century, plant specialists worldwide have sought to transform healing plants in African countries into pharmaceuticals. And for equally as long, conflicts over these medicinal plants have endured, from stolen recipes and toxic tonics to unfulfilled promises of laboratory equipment and usurped personal patents. In Bitter Roots, Abena Dove Osseo-Asare draws on publicly available records and extensive interviews with scientists and healers in Ghana, Madagascar, and South Africa to interpret how African scientists and healers, rural communities, and drug companies—including Pfizer, Bristol-Myers Squibb, and Unilever—have sought since the 1880s to develop drugs from Africa’s medicinal plants. Osseo-Asare recalls the efforts to transform six plants into pharmaceuticals: rosy periwinkle, Asiatic pennywort, grains of paradise, Strophanthus, Cryptolepis, and Hoodia. Through the stories of each plant, she shows that herbal medicine and pharmaceutical chemistry have simultaneous and overlapping histories that cross geographic boundaries. At the same time, Osseo-Asare sheds new light on how various interests have tried to manage the rights to these healing plants and probes the challenges associated with assigning ownership to plants and their biochemical components. A fascinating examination of the history of medicine in colonial and postcolonial Africa, Bitter Roots will be indispensable for scholars of Africa; historians interested in medicine, biochemistry, and society; and policy makers concerned with drug access and patent rights.

Book Description
The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.

Book Description
Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.
