Opis

The Succulent and Nama Karoo form part of the arid southwestern zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book is the first to synthesize these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics, and anthropogenic influences. The contributions offer novel analyses of the factors distinguishing the Karoo from other temperate deserts and challenge generalizations about semi-arid ecosystems.

Review of the hardback: 'This book provides insight … I loved it. I loved it for the depth of information and the logical presentation, for the beauty of the academic language and the pictures it created in my mind.' Winescape
