Soil to roots to stem to atmosphere…

Studies show that fog water diffuses directly through leaf cuticles of Drimys brasiliensis and is transported through the xylem to below ground.

Hydraulic adjustment in a pine species across its range

The ability of P. canariensis to inhabit a wide range of ecosystems seems to be associated with high phenotypic plasticity.

A bee’s eye view of flowers

The large, tunnel-like, dark-red flowers of Iris atropurpurea are likely to have evolved to mimic protective shelters preferred by male solitary bees.
