Phytocoenologia, founded in 1973 by R. Tüxen, publishes original papers in the fields of vegetation ecology. The journal covers all aspects of phytosociology in a comprehensive sense, i.e. including interactions betweeen plant (and animal) organisms (coenological geobotany), the history and origin of phytocoenoses, vegetation dynamics, floristic and structural analysis of the plant cover (classification and ordination), fundamental environmental studies of plant ecosystems (synecology), pattern analyses from the ecosystem to the landscape level, and aspects of reproduction, dispersal and population biology in plant communities. The journal is open to methodological, theoretical, experimental and applied approaches. The contributions should appeal to an international readership. Papers whose content is restricted to purely syntaxonomical and nomenclatural aspects or to local vegetation studies will not be accepted. Supraregional, synoptic views and com- parative studies of vegetation types are welcome. Thematic issues devoted to current topics and special volumes (e.g., with selected contributions of I.A.V.S. and F.I.P.-Symposia) are also be considered for publication.
