Anatomical, physiological and chemical differences between populations of Pseudocyphellaria flavicans (Hook. f. & Taylor) Vain. from Chile
Environmental conditions can affect lichen morphology, physiology and chemistry. Some functional traits; like thickness of thallus layers, photosystems condition, and presence of photoprotective and antioxidant compounds are key to colonizing new sites, and can change depending on light and moisture...
