  • The cactus life-form is cited as an example of a tight relationship between organism form and function: a succulent, long-lived, photosynthetic stem allows cacti to survive long periods of drought while maintaining a positive tissue water status. [...] Key Method We selected seven Pereskia species, representing both clades, and characterized their water relations by measuring a suite of physiological traits in wild populations.Expand Abstract
