Abstract:
... Although changes in biodiversity and in ecosystems are surely caused by a range of interacting drivers, such as natural or human-induced factors, one of the important drivers having major impacts on climate and biodiversity and leading to range changes and fragmentation is global warming. Defining past range changes/fragmentations during interglacial periods may provide tools to understand possibl ...

Abstract:
... Geometric analysis of the morphological elements in a fault-controlled environment is a widely used application to investigate active tectonics. In this study, we analyze recent topographical data to reconstruct an inherited landform assumed to have been formed and then continuously deformed by multiphase tectonics. Retracing the steps of this complex evolution would allow for the parameters of th ...
