Figure 3: SCDPD-inferred population density change 8,000–4,000 cal. BP for each sub-region.
From: Regional population collapse followed initial agriculture booms in mid-Holocene Europe

Statistically significant deviations from the null model (see Methods) are indicated in red and blue, and blue arrows indicate the first evidence for agriculture in each region. **P-values smaller than P<0.0051, the 95% confidence level calculated using the Šidák correction (see Methods).
