En savoir plus sur le livre

The Guiana Highlands feature some of the world's most stunning yet least explored mountains, known as `tepuis`, characterized by immense sandstone plateaus surrounded by towering cliffs. These isolated summits have preserved unique flora, fauna, and landscapes for millions of years. This work delves into the discovery and exploration of these extraordinary mountains, highlighting the distinctive ecosystems found atop these enigmatic terrains. The introductory chapters detail the geological processes that shaped the tepuis, followed by a review of the Amerindian perceptions of these formations before European discovery, spanning from the 16th Century to early 20th Century explorations of Mount Roraima. Subsequent chapters explore the physical landscape and geological features of the tepui summits, the unique evolutionary processes that define their biological environments, and the remarkable diversity of life adapted to the challenging highland conditions. The final chapter addresses contemporary conservation and management issues facing the region. This comprehensive study is richly illustrated with 248 figures, including stunning images and historical illustrations, making it accessible to both specialists and general readers alike. It serves as an invaluable resource for anyone interested in the natural history of these remarkable tablelands.
