Palaeoecological study of vegetation dynamics in the Neotropical Gran Sabana since the Late Glacial = Estudio paleoecológico de la dinámica de la vegetación en la Neotropical Gran Sabana desde el Tardiglaciar

The Gran Sabana (GS, Northern South America) is a humid savanna region (treeless savanna intermingled with forest patches) with a long history of vegetation changes under fire disturbances. A number of hypotheses seek to explain the importance of environmental factors (e.g., climate, fire) in the origin and maintenance of the GS savannas. In order to fully comprehend the ontogeny of the GS, this thesis was aimed at conducting a detailed palaeoecological evaluation of vegetation dynamics and ecological processes (e.g. feedbacks, resilience) from the Late Glacial to the present, analysing two se...
