Moulatlet, G.M., Kusumoto, B., Pinto-Ledezma, J., Shiono, T., Kubota, Y. & Villalobos, F. (2023) Global patterns of phylogenetic beta-diversity components in angiosperms. Journal of Vegetation Science, 34, e13203. https://doi.org/10.1111/jvs.13203
In this article, Gabriel Moulatlet and co-authors compiled distribution range maps for 207,146 species of angiosperms and conducted the first global assessment of phylogenetic beta diversity (PBD) patterns for this group. They decomposed PBD into turnover and nestedness components and found that in most areas, lineage replacement was more important than lineage loss. However, the importance of lineage loss (nestedness) increased at higher latitudes, at higher elevations and on islands and peninsulas. They also compared taxonomic beta diversity with PBD and showed that species exchanges were more important overall than lineage exchanges and that the importance of species exchanges relative to lineage exchanges even increased toward higher latitudes and low-temperature areas. This study demonstrates that global PBD patterns in angiosperms are related to geographic and environmental gradients and reflect evolutionary and biogeographic history.
The 2023 Editors’ Award for Applied Vegetation Science goes to Aure Durbecq.
Durbecq, A., Bischoff, A., Buisson, E., Corcket, E. & Jaunatre, R. (2023) Using priority effects for grassland restoration: sequential sowing can promote subordinate species. Applied Vegetation Science, 26, e12748. https://doi.org/10.1111/avsc.12748
In this article, Aure Durbecq and colleagues explored the sequential sowing of dominant and subordinate plant species to answer the question of whether the order of arrival influences the establishment of restored communities. Overall, the authors found subordinates benefited from being sown first, challenging the conventional approach of seeding all target species simultaneously, which limits the establishment of subordinate species. This approach, asking the age-old question of how to re-establish plant communities, used community assembly theory on priority effects to explore restoration success. The authors also found some species-specific effects, emphasizing the need for a better understanding of the predictability of priority effects.
