This book provides a comprehensive, detailed, and coherent spatio-temporal account of Caribbean mangrove evolution from its evolutionary origins to the present that is not available for any mangrove region in the world. Mangroves are intertidal wetland forests that play a crucial role in the maintenance of terrestrial and marine biodiversity, and in the functioning of global biogeochemical cycles (especially the carbon cycle). These ecosystems dominate the tropical/subtropical coasts of all continents and are among the most threatened ecosystems in the world. This book combines all temporal scales, from the geological to the ecological, to provide an integrated picture of mangrove history and the natural and anthropogenic drivers of ecological and evolutionary change. This may be useful not only for understanding the current ecological status of these emblematic ecosystems, but also for informing their conservation in the face of ongoing global change.

The high-resolution palynological study of the varved sediments of Lake Montcortès has provided a unique record of the regional vegetation shifts over the last 3000 years and of the natural and anthropogenic drivers of ecological change, unparalleled in the Mediterranean. This book shows in detail how the terrestrial ecosystems of Montcortès have responded to climatic events such as the Medieval Climate Anomaly or the Little Ice Age, as well as to varying intensities of anthropogenic pressure from the Bronze Age to the present. The knowledge gained from this palaeoecological study is useful not only for understanding how the modern landscapes of the Pyrenees were shaped, but also for conserving biodiversity and ecosystems in the face of future environmental changes related to ongoing global change. The book is aimed at researchers, university teachers and advanced graduate students in a wide range of disciplines including ecology, palaeoecology, environmental science, biodiversity, geography, sedimentology, archaeology, anthropology, and biodiversity conservation.
