Beyond air-seeding: Dynamic, multiphase interactionsreveal a two-step mechanism of embolism propagation inangiosperm xylem

This paper identifies a two-step mechanism of embolism propagation in angiosperm xylem, involving bubble generation and embolism formation as distinct processes.

Interconduit pit membranes of temperate angiosperms undergo changes in pit membrane thickness and electron density within the final growth ring

The paper examines seasonal changes in pit membrane thickness and electron density within the latest growth ring of angiosperm xylem conduits across eight species.

Continuous monitoring of plant transpiration dynamics with a leaf-mounted sensor across environmental conditions

The paper evaluates the FylloClip sensor for continuous transpiration monitoring under various environmental conditions and finds it correlates strongly with IRGA measurements.

Beyond species means - the intraspecific contribution to global wood density variation

Across 109,626 wood density records from 16,829 plant species (GWDD v.2), intraspecific variation explains 15% of global variance, tracks interspecific environmental gradients at 20-30% magnitude, and limits single-plant predictability.

Stochastic spreading models reproduce embolism propagation dynamics in angiosperm xylem networks of vessels connected by bordered pits

The paper uses a stochastic SI model to simulate embolism propagation in plant xylem networks, reproducing empirical and physiological results without detailed physiological data.

A global map of wood density

The paper creates a high-resolution global map of wood density using species and vegetation data, showing improved accuracy and a wider density range than previous estimates.

Thermal acclimation of stem respiration reduces global carbon burden

The paper predicts and validates the temperature sensitivity of stem respiration, showing thermal acclimation reduces global carbon emissions.

Time-based shifts in xylem vulnerability curves of angiosperms based on the flow-centrifuge method

This study shows that spin time affects xylem vulnerability curves in angiosperms, leading to shifts in hydraulic conductivity and P50 values when using the flow-centrifuge method.
