Abstract:<p>Scree slopes offer an environment conducive to the occurrence of several gravity-driven geomorphic processes, the frequency and magnitude of which are highly variable in time and space. These processes locally prevent vegetation colonization, despite the climatic warming that favors a general progression and consolidation of forest fronts, and this from an altitudinal as well as a latitudinal point of view. The position of the forest front is therefore due, in addition to the climate, to the g… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
