Determine whether inferred stability regimes predict future community reorganization

Determine whether the stability regimes inferred from abundance time series anticipate future reorganization of natural ecological communities.

Background

The framework classifies communities into stability regimes, including stable coexistence and quasi-extinction, and estimates species-level quasi-extinction risks from abundance data. For several datasets, these classifications agree with prior ecological evidence, but the interpretation is less straightforward for the Women Gut microbiota dataset: enterotype transitions suggested a quasi-extinction regime, whereas the inferred dynamics were closer to stable coexistence.

The authors therefore leave unresolved whether the regimes inferred by the method have predictive value for subsequent changes in community composition. Resolving this issue would test whether the framework can forecast future ecological reorganization rather than merely classify historical abundance dynamics.
