The Sahara is one of the most fascinating regions on Earth. People have always been magically drawn to it. This book describes this largest dry desert in the world as a habitat. It begins by presenting the geological history and climatic conditions that led to the formation of this desert. Following that, the biology of the plants and animals is explored, with a particular focus on their adaptations to the extreme living conditions. In the chapter "Plants of the Sahara," around 250 plant species are illustrated and described based on their characteristic features. The landscape and its wildlife are also depicted with numerous photographs, mostly taken by the author himself. Illustrative graphics are used to clarify relationships. What is demonstrated through the example of the Sahara can also be applied to other arid regions. Anyone interested in deserts and their natural aspects will find valuable information in this book.
