Acute environmental perturbations are reported to induce deterministic microbial community assembly, while it is hypothesized that chronic promote development of alternative stable states. Such acute or strongly impact on the pre-adaptation capacity perturbation. To determine importance level and assembly processes following in context hydrocarbon contamination, a model system pristine polluted (hydrocarbon-contaminated) sediments was incubated absence presence (discrete repeated) amendment. The structure changed significantly perturbation, with selection different phylotypes not initially detectable. Conversely, historically maintained initial structure, historical legacy effect pollution likely facilitated stability. An state also reached further demonstrating existence effect. Finally, ecosystem functional resilience demonstrated through occurrence degradation by communities tested sites, but perturbation influenced biotic response. This study therefore demonstrates chronicity reveals
