coenosis

Definitions

A group of organisms within a particular habitat or ecosystem, along with their interactions within that environment; the subset of an ecosystem that focuses solely on living (biotic) participants.

Examples

“The two processes cannot be separated; modification of species causes a change⟳ in phytocoenic and ecologic relations between the plants of a coenosis, and therefore create⟳ a new coenosis altogether; whereas modification of the coenosis entails in its turn⟳ a further evolution of species within the coenosis (i.e., phylocoenogenesis).”

“For various coenoses, the threshold concentrations of methanol differ⟳ sharply; it was less than 1% for the Karelian lake, approximately 4% for the stream mouth, and around 6% for the aeration coenosis.”

“With time sparsing of sporophytes through the intraspecific and interspecific (with other plants in the coenosis) competition takes place⟳ in the loci, and the sporophytes get⟳ established in the herbal cover⟳ of the coenosis.”
