The effects of simulated acid precipitation on photosynthesis in the caribou lichen Cladina stellaris (Opiz) Brodo

The effects of simulated acid precipitation on photosynthesis in the caribou lichen Cladina... Abstract The photosynthetic capacity of the caribou lichen,Cladina stellaris, was impaired when the lichen was wetted by artificial acid precipitation. When wetted by a solution having a pH=4.0 and a sulfate concentration = 10.00 mg l−1, the maximal photosynthetic capacity was lowered 27% from normal levels. Moreover, the lichen which is dormant when dry, took 14% longer after wetting to attain even this reduced rate of photosynthesis. The possibility that lichen growth rates may be reduced by acid precipitation with serious implications for many northern ecosystems is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Water, Air, & Soil Pollution Springer Journals
