| Résumé : |
Alpine landscapes include strong abiotic gradients, which promote the coexistence along short distances of varying plant communities. Here, we analyse the vegetation of the alpine belt of the Catalan and Andorran Pyrenees through functional plant traits, to better understand plant diversity as coupled with the varying alpine landscapes. For this purpose, we used 800 phytosociological relevés to characterize the associations in terms of plant traits, and to relate them to species diversity and functional properties. Most of the community‑types assessed reflect the distinct stressing conditions found in alpine environments, and are species‑poor at the plot level. This is more evident in particularly limiting environments, such as scree, rocky areas or snowbeds which, however, host many singular species in the biogeographic and functional aspects. Most grassland vegetation reflects better ecological conditions; community‑types are species‑richer, and include great regional and ecological variation. Alpine heaths respond to the local fitness of a few woody species able to exert dominance through persistence. There is still a lack of knowledge on the actual effect of grazing on the relative role played in contemporary landscapes by alpine heaths and grasslands. |
