Temperature governs the relative contributions of cuticle and stomata to leaf minimum conductance. [PDF]

New Phytol
Summary During periods of stomatal closure, such as drought, plant leaves continue to lose water at a rate determined by the minimum leaf conductance, gmin. Although gmin varies with temperature, less is known about what drives this variation, including how the pathways of water loss (cuticle or stomata) vary with temperature.

Wave effect and shyness phenomenon in homogeneous forests of Alnus acuminata

Sustainable Forestry, 2022
The wave effect and the shyness phenomenon in Alnus acuminata (Kunth) are crown parameters rarely studied, but important in the quality of the wood of standing trees, therefore, a morphometric modeling of the crowns of Alnus acuminata in homogeneous forests in the Sierra Norte de Puebla was carried out.
