VEGETATION STRUCTURE AND SPECIES COEXISTENCE

''Vegetation Structure and Species Co-existence'' was the topic of a s ymposium organized in 1992, in Tartu, Estonia. The symposium was dedic ated to the memory of Professor Teodor Lippmaa (1892-1943), who made i mportant contributions, especially to the concept of synusia in commun ity ecology. Current views on relation between vegetation structure an d species co-existence vary. This variation is partly due to the tradi tional opposite views of plant community structure (the individualisti c and organismic concept); these views refer both to the strength and role of biotic interactions within a community, and to the community s tructure.
