Extended Data Fig. 7: Representation of the mixed-effects models.
From: The rise and fall of proboscidean ecological diversity
Relationship of local species richness with age (a), and averaged DMD (b) across different phases. Density plots show the distribution of average DMD scores in each phase. A schematic comparison of slopes and intercepts is included, showing whether parameters estimates are significantly larger (>), significantly smaller (<), or not significantly different (≈).
