Admixture between differentiated populations is considered to be a powerful mechanism stimulating the invasive success of some introduced species. It is generally facilitated through multiple introductions; however, the importance of admixture prior to introduction has rarely been considered. We assess the likelihood that the invasive Ambrosia...

Dispersal may be strongly influenced by landscape and habitat characteristics that could either enhance or restrict movements of organisms. Therefore, spatial heterogeneity in landscape structure could influence gene flow and the spatial structure of populations. In the past decades, agricultural intensification has led to the reduction in...

Avant d'entamer le dossier, voici un petit glossaire à l'usage des gestionnaires de la résistance aux produits phytopharmaceutiques.La résistance aux PPP est un phénomène souvent complexe, faisant appel à des notions de biochimie, génétique, sciences de l'évolution. De ce fait, pour apprécier au mieux les articles de ce dossier, il apparaît...

Monitoring resistance to plant protection products (PPPs) is crucial for understanding the evolution of resistances in bioagressors, thereby allowing scientists to design sound bioagressor management strategies. Globally, resistance monitoring is implemented by a wide range of actors that fall into three distinct categories: academic,...
