The PSInet Plant Water Potential Database: advancing new perspectives on plant water status, traits, and hydraulic processes

The paper introduces the PSInet database, a global collection of plant water potential time series, and highlights its potential for various ecological and physiological studies.

Linking drought strategy to climate of origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

This study examines how hydraulic, stomatal, and anatomical traits in Themeda triandra relate to climate-of-origin, revealing two distinct drought strategies in different climatic conditions.

Lack of co-ordination of stomatal, hydraulic and leaf browning traits in 16 perennial Australian grass species of differing climate origins

The paper examines drought response mechanisms in 16 Australian grass species, finding that stomatal closure, hydraulic impairment, and leaf browning occur simultaneously, unlike in trees, and drought traits are not correlated with climate origin.

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.

Drought, thermal response and climate-patterning in cuticular conductance of the widespread C4 grass, Themeda triandra

This study examines how drought and temperature affect cuticular conductance in six Australian accessions of Themeda triandra, finding climate-linked patterns under drought but no thermal threshold.

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.
