Shrnutí: How biological diversity is maintained in time is a fundamental question in a global change context. Ecologists have delineated many mechanisms that could maintain biodiversity stability and affect ecosystem resilience or resistance towards environmental changes. These mechanisms (compensation by species asynchrony, dominant species and portfolio effects) have been traditionally attributed to species diversity effects, but evidence is accumulating that they operate through differences in functional traits between species. Trait variability within species should further allow for stabilizing effects via abiotic plasticity and trans-generational trait adjustments induced by species interactions. We propose to test the importance of different stability mechanisms with globally available long-term datasets, regional data from meadow- systems and data from field and greenhouse sowing experiments. The data will be analysed using a novel framework based on functional traits within and between species, including the development of new measures for species synchrony and functional redundancy.
