We believe this approach may open new pathways to assess biodiversity change. Observed and dark diversity allow decomposing winners and losers in diff ways: species increasing or decreasing in both observed and dark, or in only one, indicating rapid, delayed, or expected expansions and contractions.

72% of species showed time-lagged responses: many cold-adapted and commercially important species persist locally with declining suitability, while others have become more frequent in the region and locally suitable but remain absent across multiple sites (i.e. mostly smaller and less motile).

No net change in species number - neither observed nor dark diversity changed over time(!), yet: - species persisting locally showed a decreasing suitability (i.e. extinction debt); - this pattern was stronger for larger and more mobile species

We used a stable number of observed species over time but declining suitability as a signal of extinction debt (i.e. persisting species with declining suitability), and a faster increase in dark diversity size than observed diversity as a signal of immigration credit.
