X. Glossary of terms | 175 Stratocoenosis — a coenosis of animals that only occur at a certain level (stratum) of a plant association (e.g. only living on roots) (Tischler) Stratum - “layer”; a vertical division of the biotope (Tischler 1947, 1950), equivalent ofa bioroph (Thalenhorst 1950, 1951) Supersocion - an animal associational category above the presocium, and the presumed limit of animal communities that unites food chains with energy sources of a whole biotope Sustinent - (sustaining) structural element of a biocoenosis; plants or animals that underpin the survival of others as symbionts or reproductive agents (e.g. pollinators) Synbiology - study of biology at the level above populations Synchorology - the study of distribution of plant communities, phytosociological zones, vegetation and geographical complexes Synchronology - the study of changes in associations through time Synecology - the study of ecology at the level of the associations/community, ie. above populations Syngenetics - field of research in plant sociology and zoocoenology that examines developmental history of associations Synmorphology - field of research in plant sociology and zoocoenology that examines structure, composition and organisation of associations Synphysiology - study of metabolic processes of plant species and communities in competition Syntaxonomy - system of associated categories of vegetation units of a given area as understood by phytosociologists Syntrophium - equivalent of a guild. Organisms with similar feeding habits in a specific habitat. Synusium - a structural unit of a major plant ecological community characterized by relative uniformity of life-form or of height. Used by Balogh for animal associations of a bioroph Syrmatophagous - feeding on dry plant material Technocoenosis — an association created by humans Terriherbosa — sub-division of Rtibel’s (1930) plant formation types; herbosa (herbaceous formations) Tocogenetic - of or concerning the relationships between individuals in a species to describe the ancestor-descendant relationship, as from mother to daughter across generations (Hennig 1950) Transformatum — biomass produced from inorganic components (i.e. transformed from those) Also termed ‘assimilatun’ Tychcoen - sub-categorisation (of eucoen) of animal associations sharing the same space (Tischler 1947, 1950)) Valence - valency; tolerance limits Vicini - (= neighbours) from Tischler’s (1947, 1950) classification; a subgroup of peregrinant organisms in a spatially delimited zoocoenosis arriving from neighbouring locations (see alieni)
