88275 - GEOSYSTEMS RESPONSE TO QUATERNARY GLOBAL CHANGES

Conoscenze e abilità da conseguire

Under the threat of sea-level rise and global warming, data preserved within the recent sedimentary record are playing an increasingly important role in conservation biology practice and policy. The aim of this course is to promote understanding of how past patterns of variability can aid the development of more effective biodiversity conservation strategies and ecosystem management in the face of climate change. In this course, we will introduce elements of paleoecology, stratigraphy and paleoclimatology in order to analyze how the Quaternary record can be used to understand the ecological and environmental responses to climate changes. This course will also highlight the utility of fossils in providing a reference baseline for evaluating severity and significance of the anthropogenic impact on present-day ecosystems and their biodiversity. Methods and best practices to integrate paleontological, ecological and sedimentological data for a multidimensional view of past ecosystems are presented and discussed. Finally, the course is integrated by laboratory training on the field and will be offered an opportunity to analyze environmental dynamics in response to past climatic-eustatic perturbations directly on outcrops and/or cores.
