Using iron chelation as a measure of biochemical weathering, and employing a spectrometric technique to measure the chelation, the authors studied rock lichens and fungi isolated from the same rock surfaces. The isolated symbionts (mycobionts and phycobionts) of four species of lichens showed no chelation ability after growth on synthetic media. Squamatic acid extracted from the lichen Cladonia squamosa chelated iron in solution. Many of the fungi isolated from the same sandstone, particularly species of Penicillium and Cephalosporium, were able to chelate iron in solution from twice to as much as six times that of the squamatic acid, as was true for citrate. Lichens that produce lichen acids and rock-surface fungi may be significant biochemical weathering agents in nature.
Biological Conservation | 1970

Abstract With increased world interest in conservation and environmental protection, it is especially proper that the only continent set aside for international scientific investigation, Antarctica, should be a model for conservation practices. The Antarctic ecosystems, because they mostly survive under extreme environmental conditions, are very fragile, being easily disturbed without our knowing how long regeneration may take. Fortunately there are good conservation regulations in the Antarctic Treaty, and these are being strengthened by periodic recommendations of the Working Group on Biology of SCAR. Scientists and others who visit Antarctica must take responsibility for implementing these recommendations.
