Grasses occupy a greater area of the world's land surface than any other plant family, occurring in almost every terrestrial environment and providing a vital source of food for humans and animals. This volume presents the most recent information on their population biology, bringing together contributions from researchers studying both applied and fundamental aspects of this important group of plants. Demographic, physiological, ecological and molecular approaches to understanding grass populations are considered in relation to reproduction and to aspects of life history patterns such as dispersal, germination, seedling establishment, population dynamics and reproduction. Other areas coveredinclude the role of genetic variation and phenotypic plasticity in shaping life history traits, the impact of biotic factors, and the ecology of specific species in major grass-dominated ecosystems in Africa, Australia and Japan.
