Relationships between productivity, quality and traits in seven co-occurring grass species
Plant functional types approach : a tool to analyse sward structure and vegetation dynamics in wet grasslands ?
The interspecific plant competition affects the production and the nutritive value of grassland species.
Five grassland species (Dactylis glomerata, Festuca arundinacea, F. rubra, Poa pratensis and Trisetum flavescens) were cultivated in monoculture and in mixture with a highly competitive cultivar of Dactylis glomerata (Lupre) in 2002 at Theix, Massif Central, France. This setup aimed to evaluate the impact of species interactions on the productivity...
One century of vegetation change on Isla Persa, a nunatak in the Bernina massif in the Swiss Alps
Question: How did the vascular plant species composition of a nunatak in the alpine vegetation belt change over a time span of one century? Location: A 0.056-km2 nunatak, Isla Persa in the Swiss Alps, that remained ice free during the last maximum glacier advance in the 1850s and is today partly covered with climactic alpine grassland and dwarf hea...
Assessing the dominance of Phleum pratense cv. climax, a species commonly used for ski trail restoration
Questions: (1) Are some species used for ski trail restoration too dominant to allow native species to re-establish? (2) What plant traits can be used to predict which species are good competitors? We tested the hypothesis that limited native species establishment on ski trails is caused by (1) the dominance of Phleum pratense cv. climax (PPC)and (...

Pression d'herbivorie et dynamique des communautés végétales : influence à court et moyen termes des populations de cerv...
Les cervidés, animaux mobiles et herbivores, peuvent influencer les distributions, assemblages et dynamiques d'espèces végétales. L'objectif de cette thèse est d'évaluer le rôle joué par les cervidés sur la composition, stratification et dynamique de la végétation forestière. Le ré-échantillonnage de relevés couplant composition et abroutissement de ...
Responses of five woody species to burial by marly sediment: the role of biomass allocation pattern flexibility.
Aims In eroded lands of the French Southern Alps , burial of early established seedlings under marly sediment weakens the effect of vegetation on soil stabilization and sediment trapping. Therefore , this protective role is largely dependent on species ' resistance to burial , and the understanding of species ' tolerance to this environmental distu...
