Erophila verna ; seed production ; germination capacity of seeds ; density-dependent reproduction of individuals ; many years' population abundance dynamics

The dynamics was studied of natural aggregations of Erophila verna individuals and the seed germination capacity under laboratory conditions. A significant, negative correlation has been found between the number of seedlings and of adult individuals in the particular year, and the number of seedlings the next year, and a positive correlation between the number of seeds in the soil and the number of individuals of the new generation. It has been demonstrated that the numerical equilibrium of the population over a many-years’ cycle is determined by natality differences among the aggregations of individuals.
