Pearson, L/ Skye, E 1965: Air pollution affects patterns of photosynthesis in Parmelia sulcata, a corticolous lichen. - Science148: 1600-1602. [RLL List # 58 / Rec.# 14272] Keywords: AIR POLLUTION/ SO2/ PARMELIA SULCATA/ SWEDEN/ WATER RELATIONS
Abstract: 2 fig. ["Lichen disks kept in flasks contaminated with sulfur dioxide showed morphologic and photosynthetic abnormalities similar to those of lichens from an industrial center in Sweden, but lichens dried out for 4.5 to 6 months in the laboratory showed neither. This some kinds of lichens may be absent from city environments because of atmospheric pollutants which destroy chlorophyll."]
