Objectif In Europe and worldwide, many plant communities are increasingly becoming dominated by introduced species. Invasive alien species (IAS) have caused severe environmental changes globally by altering species composition and ecosystem function and are considered a major threat to biodiversity. Consequently the Action Plan for Biodiversity advocates a comprehensive strategy at EU level to reduce the impact of IAS. This proposal aims to merge perspectives from plant evolutionary, functional and community ecology with those from simulation modeling to reveal the processes underlying plant invasions and improve our statistical framework for studying and preventing them. There are 4 research objectives: the first two objectives rely on theoretical modeling while the third and fourth aim to apply the knowledge acquired from the theoretical modeling part to empirical data in the French Mediterranean and Alpine region. In particular, the project will 1) develop and validate a process-based simulation model to explore how environmental and biotic filters for local community assembly are reflected in invasion patterns using virtual data, focusing on the importance of the spatial scale and of different mechanisms of competition; 2) test the ability of current statistical methods to disentangle patterns resulting from overlaying filters and provide guidelines for improved method performance using simulated data; 3) apply the improved statistical methods on French Mediterranean and Alpine plant communities to explore shifts in dominant invasion processes across environmental gradients and invasion stages; 4) attempt to parametrise the developed process-based model through a novel Bayesian approach in order to quantify the relative importance of environmental and biotic filters for successful invasions. The outcome of the project will be of high relevance for both scientific knowledge-building in the field of invasion ecology and the support of decision makers in invasion management Champ scientifique natural sciencesbiological sciencesecologyecosystems Programme(s) FP7-PEOPLE - Specific programme "People" implementing the Seventh Framework Programme of the European Community for research, technological development and demonstration activities (2007 to 2013) Thème(s) FP7-PEOPLE-2012-IEF - Marie-Curie Action: "Intra-European fellowships for career development" Appel à propositions FP7-PEOPLE-2012-IEF Voir d’autres projets de cet appel Régime de financement MC-IEF - Intra-European Fellowships (IEF) Coordinateur CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS Contribution de l’UE € 194 046,60 Adresse RUE MICHEL ANGE 3 75794 Paris France Voir sur la carte Région Ile-de-France Ile-de-France Paris Type d’activité Research Organisations Contact administratif Guillaume Rochet (Mr.) Liens Contacter l’organisation Opens in new window Site web Opens in new window Coût total Aucune donnée
