Abstract

The AA. investigated the use of bomb-C 14 analysis to determine the growth rate of a different crustose species (Pertusaria pseudocorallina) common to Northern Europe, recovered near Lochearnhead, central Scotland. C 14-based growth rates were considerably higher than growth rates of morphologically similar species based on direct measurements made at locations nearby and elsewhere in the UK. This result suggests that a degree of carbon turnover probably occurs in Pertusaria pseudocorallina, and that bomb-C 14 analysis alone cannot be used to determine lichen age or absolute growth rates in this lichen species
