Аннотация:Five types of life history are distinguished among herbaceous species
growing in steppe grasslands in Kazakhstan: they include tussock plants,
tap-rooted plants of various kinds and long-rhizome herbs. They vary in
the structure and dynamics of their coenopopulations and in the extent to
which they are maintained in coenoses by seed or by vegetative growth. An
understanding of the morphology and ontogenetic development of plants
in natural coenoses is an indispensible prerequisite for describing their
coenopopulation characteristics. These in turn reveal how plant communities
are organised as dynamic systems
