Plants originating from more extreme biomes have improved leaf thermoregulation.
Article in Annals of botany, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
aimsMany plants have some capacity for leaf thermoregulation via stomatal conductance (gsw), such that leaf temperature (Tleaf) is rarely coupled with air temperature (Tair). The difference between leaf and air temperature (thermal offset, ΔT) and the slope (thermal coupling strength, β) is mediated by interactions between the immediate environment of the plant and its leaf traits. The aim of this study was to determine whether species originating from biomes with contrasting environmental conditions (alpine, desert and coastal temperate) would differ in their tendency to thermoregulate in a common environment.
methodsUsing benign-temperature (25 °C) and high-temperature (38 °C) glasshouse treatments, we measured paired canopy Tair and Tleaf for 15 diverse species, 5 from each biome, in a common garden experiment. Instantaneous stomatal conductance and a suite of leaf traits were measured and calculated to test for associations with leaf thermoregulation. KEY
resultsWe found clear evidence for greater leaf cooling occurring during high-temperature exposure, especially in alpine and desert species. The leaves of temperate species were largely warmer than air in both treatments. Thicker leaves with higher water content and high stomatal conductance clearly were more effective at cooling. Species originating from different biomes displayed divergent responses of thermal offset and thermal coupling with leaf traits.
conclusionsOur findings suggest that plants originating from more extreme biomes have innately greater scope for thermoregulation, especially desert plants, which could better counter the risk of reaching excess temperatures at the cost of higher water loss. Leaf thermoregulation is a complex plant-environment interaction, and our work contributes to the development of more accurate predictions of leaf temperature during heat exposure across diverse species and biomes.
