ANTHROPOGENIC DISTURBANCES OF TERRESTRIAL ECOSYSTEMS: FROM ORGANISMS TO ECOREGIONS
The disturbances of terrestrial ecosystems are deeply marked by the impoverishment of biocenosis and the multiplication of permanent agricultural areas and wastelands with impoverished or polluted soil. Climate change is another major threat with less visible consequences. Mitigating and addressing these changes requires understanding and monitoring the processes involved in order to implement actions on the ground. Processes are studied using a variety of methodological approaches, ranging from direct observation of organisms in their habitat to remote sensing and modelling including habitat movement, crop yield and disease prediction, plant growth and distribution, and pollination.
The session will focus on such studies, their integration and their scaling up into mechanistic models to improve regional scale understandings of ecosystem functioning, offering the opportunity to explore the relevance of planned mitigation and remediation measures.
