Plant population dynamics in grasslands.

Instability in the botanical composition of grasslands is discussed with reference to the demography of the sexual reproductive pathway, the demography of clonal species, the use of demographic studies, and aspects to consider before starting demographic study. Methods of measuring the survival of mature plants, seed set and seed fall, seed banks, seedling establishment and survival, clonal growth, changes in the genetic composition of populations, clonal demography at the phenotype level, population density, and population fluxes are described mainly for forage grasses and legumes.
