Extended Data Fig. 9: Comparison of CHELSA climate variables that differ significantly in comparing V. hartwegii (IGE) to V. jucundum (LPT) and V. lautum (SGE) across the geographic range of Oreinotinus.

Compared across the entire range of Oreinotinus, IGE species differ significantly from LPT and SGE species in ways that align with our findings for the niches of the V. hartwegii in comparison with V. jucundum and V. lautum (see Methods). Specifically, we find that IGE species grow at lower elevations with higher temperatures and higher precipitation throughout the year, and lower temperature ranges and seasonality. Viburnum hartwegii was compared in detail with V. jucundum and V. lautum on the Central Plateau of Chiapas, Mexico (see Fig. 4). In making comparisons across the range of Oreinotinus we used data for the entire geographic ranges of our three focal species (that is, extending beyond the central Plateau of Chiapas; see Extended Data Fig. 3). Hypothesis testing method, box plot elements and density ridges formulation as in Extended Data Fig. 8. N = 2783 (1416 IGE, 713 LPT, 654 SGE specimens).
