[CBNPMP-Thèmes] RevégétalisationRésumé : Les zones naturelles sont le résultat de constructions historique et culturelle. Elles constituent des espaces dynamiques en raison des transformations physiques et écologiques que divers groupes et usages leur imposent, mais elles sont également le fruit de l’évolution et de la diversité des représentations qui se différencient dans le temps et au sein de la société.

[CBNPMP-Thèmes] Diversité génétiqueRésumé : A growing number of restoration projects require large amounts of seeds. As harvesting natural populations cannot cover the demand, wild plants are often propagated in large-scale monocultures. There are concerns that this cultivation process may cause genetic drift and unintended selection, altering the genetic properties of the cultivated populations and reducing their genetic diversity. Such changes could reduce the pre-existing adaptation of restored populations and limit their adaptability to environmental change. We used single nucleotide polymorphism (SNP) markers and a pool-sequencing approach to test for genetic differentiation and changes in gene diversity during cultivation in 19 wild grassland species, comparing source populations and up to four consecutive cultivation generations. We linked the magnitudes of genetic changes to the species' breeding systems and seed dormancy to understand the roles of these traits in genetic change. Cultivation changed the genetic composition across cultivated generations only moderately. The genetic differentiation resulting from cultivation was much lower than the natural genetic differentiation between different source regions. The propagated generations harboured even higher gene diversity than wild-collected seeds. Genetic change was stronger in self-compatible than self-incompatible species, probably due to increased outcrossing in monocultures. Synthesis and applications. Our study suggests that large-scale seed production maintains the genetic integrity of natural populations. Increased genetic diversity may even indicate increased adaptive potential of propagated seeds, which would make them especially suitable for ecological restoration. Yet, it remains to be tested whether these molecular patterns will be mirrored also by plant phenotypes. Further, we used seeds from Germany and Austria, where the seed production is regulated and certified, and we do not know yet whether other seed production systems perform equally well.

[CBNPMP-Thèmes] RevégétalisationRésumé : 1 Restoration is normally conducted with the goal of creating plant populations that establish, survive, successfully reproduce, contribute to ecosystem function and persist in the long term. Restoration often relies on revegetation that, on large scales, requires agronomic increase of native plant materials. During this propagation process, restoration populations are subject to genetic sampling as well as natural and artificial selection that could result in adaptation contrasting sharply with that of native populations. 2 Here we draw on insights from the evolutionary and agricultural literature to illustrate how changes in the amount and type of genetic variation in ex situ repositories (source collections and production farms) could affect plant performance in restoration. The consequences of intentional and/or inadvertent evolutionary modification of restoration materials are discussed with respect to population viability and ecosystem function. 3 Synthesis and applications. We conclude that sampling effects and intentional and unintentional selection during collection, propagation and restoration planting have the potential to diminish restored populations. We describe testing for evolutionary change in plant materials using neutral molecular markers and/or field observations. Six practices, multiple collections through time, multiple collections through space, large effective population size, provenance tracking, promoting gene flow and reducing selection comprise ‘evolutionarily enlightened management’ that decreases the potential for unintentional evolution and maladaptation.
