Moser, TJ/ Nash, TH", III 1978: Photosynthetic patterns of Cetraria cucullata (Bell.) Ach. at Anaktuvuk Pass, Alaska. - Oecologia [Berlin]34: 37-43. [RLL List # 102-49 / Rec.# 13087] Keywords: ALASKA/ PHOTOSYNTHESIS/ WATER RELATIONS/ CETRARIA
Abstract: 1 figure. ["With the exception of rainly periods, the lichen exhibited a strong diurnal pattern with peak photosynthetic activity occurring between 0300 and 0700 h. This correlated with periods of maximal lichen water retention and the presence of direct solar radiation. When the lichen was moist, a strong gradient in photosynthetic acitivity was observed with no activity in the lichen bases and maximal activity in the lichen tips."]
