Description
Aim  To quantify the interaction between climate and woodland continuity in determining the bioclimatic response of lichen epiphytes.
Location  Northern Britain (Scotland).
Methods  Indicator‐species analysis was used to pre‐select lichen epiphytes along parallel gradients in climate and the extent of old‐growth woodland. Nonparametric multiplicative regression was used to describe in a predictive model the individualistic response of selected species, which were projected based on climate‐change scenarios and contrasting patterns of simulated woodland loss or gain. Species with a similar response were grouped using a novel application of cluster analysis to summarize the potentially huge number of projected outcomes. Projected patterns of occurrence under climate‐change scenarios were examined for different levels of old‐growth woodland extent.
Results  Forty‐two lichen species were statistically …
