This text gives biographical accounts of the leading plant collectors and their activities in Southern Africa from the days of the East India Company until modern times.

A new edition of one of the most practical and authoritative botanical dictionaries available.

This book brings together recent and ongoing empirical studies to examine two relational kinds of politics, namely, the politics of nature, i.e. how nature conservation projects are sites on which power relations play out, and the politics of the scientific study of nature. These are discussed in their historical and present contexts, and at specific sites on which particular human-environment relations are forged or contested. This spatio-temporal juxtaposition is lacking in current research on political ecology while the politics of science appears marginal to critical scholarship on social nature. Specifically, the book examines power relations in nature-related activities, demonstrates conditions under which nature and science are politicised, and also accounts for political interests and struggles over nature in its various forms. The ecological, socio-political and economic dimensions of nature cannot be ignored when dealing with present-day environmental issues. Nature conservation regulations are concerned with the management of flora and fauna as much as with humans. Various chapters in the book pay attention to the ways in which nature, science and politics are interrelated and also co-constitutive of each other. They highlight that power relations are naturalised through science and science-related institutions and projects such as museums, botanical gardens, wetlands, parks and nature reserves.

The book provides a comprehensive overview of current knowledge about "wattles", a large clade of over 1000 species of trees and shrubs in the genus Acacia, most of which are native to Australia. It examines the biology, ecology, evolution, and biogeography of wattles in their native ranges, including the evolutionary forces that have driven past speciation and adaptation to diverse environments, the conservation status, uses and human perceptions of these species. It considers the different histories of the introductions and proliferation of wattles as alien species in different parts of the world since c. 1850 (the Anthropocene), situated within relevant political, socio-economic and scientific contexts, together with an analysis of how awareness of their impacts as invasive species has changed over time. Differences in the dynamics and trends associated with the introduction, naturalization and invasion of wattles in different parts of the world are reviewed. The book also synthesizes the global distribution of wattles using diverse data sources, alongside trends, patterns and projections of global uses of wattles. It discusses the genetics, biotic interactions, and ecological, economic and social impacts of invasive wattles. This book is aimed at academics and students in the field of ecology, and at managers of natural and anthropic ecosystems, policy-makers and regulators, and the general public interested in biology and environmental science.
