Cation ratios in Cladonia portentosa as indices of precipitation acidity in the British Isles

The relationship between rainfall chemistry and the concentrations of potassium, calcium and magnesium in the apices (top 5 mm) of the cushion-forming lichen Cladonia portentosa (Dufour) Coem. was investigated. Lichen samples, together with underlying topsoil, were collected from heathlands in close...
