Résumé en anglais

<div><p>Treefalls create gaps in the forest which contrast bright environments, where competition from large trees is reduced after a treefall, with a variety of more shaded environments, where competition from tall trees increases as gaps fill with vegetation and forest succession takes place. This process of forest gap dynamics (Martinez-Ramos et al., 1989) produces successional niches, which select species with a variety of survival and growth strategies (Hérault et al., 2010; Rüger et al., 2009). Pioneer species with fast growth, due to highly productive leaf tissue and light wood, rapidly colonize treefall gaps; whereas late successional species, with slower growth and more carbon conservative tissues, progressively establish in more shaded environments (Craven et al., 2015). However, although the ecological effects of treefall gaps on forest community composition are well understood, the role of temporal habitat heterogeneity from forest gaps as a driver of adaptive evolution within species remains unexplored.</p></div>< Réduire
