Autecology and synecology

Autecology is the ecology of a single species, its relations to its natural conditions like soil and climate. The science of the relations within the population of one species is called population ecology (mainly in Russian it is known as demoecology).

Synecology on the other hand is the ecology of different species living in the same habitat, their relations with one another.

French: autécologie / synécologie
