Abstract: [Study of daily response patterns for net photosynthesis using Santessonia hereroensis, Xanthoparmelia walteri, X. incomposita, and Caloplaca elegantisssima. "Higher fog and dew intensity in spring increased maximal nocturnal water contents, maximal attainted NP [net photosynthesis] and integrated daily carbon income ... compared to the autumn measurements." Autumn results are about 40% less than in the spring.]
