Adaxial and abaxial stomatal densities in amphistomatous plants show a significant phylogenetically corrected allometric relationship with a slope significantly greater than 1 across 559 species.
- Why it matters: Dual-surface stomatal allocation is known to vary, but the predictable scaling pattern and how deviations relate to evolutionary history and environmental context are unclear.
- What they did: Using a global dataset spanning 380 sites and 63 families, the study fit phylogenetic reduced major axis regression and computed amphistomatal scaling residuals (ASR) as signed perpendicular deviations.
- The result: ASR carries significant phylogenetic signal, does not differ by major life-history groups, and shows generally modest single-environment associations, while a phylogenetic model retains multiple interaction terms.
