Symbiogenesis is driven through hierarchical reorganization of an ecosystem under closed or semi-closed conditions
Description
Ecosystems generate selective environments and function as sources of various metabolic systems for symbiogenesis. In this study, we have explored how symbiogenesis occurs in the living world, from a holistic perspective, by observing a long-term experimental culture of an ecosystem model (CET microcosm) and using related findings in laboratory and field studies of endosymbiosis between auto- (photo-) and heterotrophic organisms. The results obtained suggest that symbiogenesis can occur in the mature stages of semi-closed ecosystems and lead to a new ecosystem-oriented perspective of symbiogenesis. Symbiogenesis is an aspect of ecosystem evolution in which whole ecosystem dynamics generate selective conditions operating on the component species, favoring symbiotic associations among some of them. The development of symbiotic associations then modifies the organization and material/energy flow structure of the ecosystem, which, in turn, modifies their selective environments.
