Abstract: We examine role of natality-related plant traits in a mountain grassland community. We use a spatially explicit, individual-based model of clonal plant population dynamics that includes traits of growth, resource allocation, response to competition, and spatial spread/plant architecture, and parameterize it for four co-occurring grass species. Field measurements of plant growth and architecture were used for parameterization; the subset of parameters that cannot be obtained by field estimation were estimated by fitting model predictions to a fine-scale time series of field data using a formalized gradient-descent procedure. The parameterized model was then validated with a separate set of fine-scale time series of field data.
