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.

Allometric models for estimating biomass and carbon in Alnus acuminata

Ciencias Ambientales, 2013
In order to quantify the climate change mitigation potential of forest plantations, information on total biomass and its growth rate is required. Depending on the method used, the study of the biomass behavior can be a complex and expensive activity. The

Nitrogen fixation and fertilization have similar effects on biomass allocation in nitrogen-fixing plants. [PDF]

Ecol Evol
It has long been known that plants adjust allocation to different tissues based on supply of soil nitrogen, but the degree to which nitrogen supplied by symbiotic nitrogen‐fixing bacteria has similar effects on allocation is less well known. Using an experiment with 15 plant species with and without access to symbiotic nitrogen‐fixing bacteria, grown ...
