Abstract:

A host of abiotic and biotic factors are known to influence the stability of ecological systems. However, the role of most of these factors for ecosystem stability is not well understood. In this talk, I will present our recent findings on how species diversity, nutrient enrichment, and interspecific competition, influence ecosystem stability. Our work indicates that there is compelling empirical evidence for a general positive relationship between species diversity and ecosystem-level temporal stability, that nitrogen enrichment strongly influences multiple dimensions of grassland compositional and functional stability, and that interspecific competition tends to increase ecosystem temporal stability. Overall, these results suggest that considering population-level stability and asynchrony in population dynamics can help understand mechanisms driving ecosystem-level stability.
