sand dunes ; Erophila verna ; relative growth rate of individuals ; density-dependent factors ; morphological diversity of individuals ; fecundity of individuals

The seasonal growth rate, morphological variability and fecundity of Erophila verna were analysed for seven years in plots differing in seedling density. The relative growth rate of individuals is independent of density, whereas the size of the vegetative organs and the fecundity of the plants are significantly correlated with the density of seedlings. With the same initial abundance of a population, seed production will thus depend on its spatial structure, that is, on the number of aggregations formed by a specific number of seedlings.
