Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Global distribution and biogeography of ericoid mycorrhizal fungi

open access: yesNew Phytologist, EarlyView.
Global predictions of local ericoid mycorrhizal fungal richness, its latitudinal trends and environmental predictors. Summary Ericoid mycorrhizal (ErM) fungi play a crucial role across terrestrial ecosystems, forming mutualistic symbiosis with Ericaceae and contributing to soil organic matter dynamics.

Phenotypic plasticity is broadly adaptive across an elevation gradient in the Cutleaf Monkeyflower

open access: yesNew Phytologist, EarlyView.
Leaf shape plasticity expression is variable in Mimulus laciniatus. Summary Phenotypic plasticity is a key mechanism by which organisms cope with environmental heterogeneity, but its evolutionary consequences depend on how plastic responses align with the broader adaptive landscape.

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

Advancing the pneumatic method to assess xylem vulnerability to embolism among distinct growth forms

open access: yesPlant Biology, EarlyView.
Our study shows that pneumatic vulnerability curves can be constructed across contrasting growth forms, with P50 showing the closest agreement across methods. Repeated relative water content measurements improved water potential estimation for graminoid culms. Abstract Drought‐driven plant mortality is closely linked to xylem embolism. Building useful,
