Mean Annual Precipitation Explains Spatiotemporal Patterns of Cenozoic Mammal Beta Diversity and Latitudinal Diversity Gradients in North America - Figure 2

Relationship of mean annual precipitation estimated from paleosols (Retallack, 2007) with North American fossil mammal (A) raw β diversity (R² = 0.43), (B) residual beta diversity (R² = 0.26) and (C) raw latitudinal turnover gradient (LTG) strength (R² = 0.25), and (D) residual LTG strength (R² = 0.37).
