Johan Asplund, Aron Sandling, Paul Kardol and David A. Wardle The influence of tree-scale and ecosystem-scale factors on epiphytic lichen communities across a long-term retrogressive chronosequence Journal of Vegetation Science 25
We tested how ecosystem retrogression affects lichen communities on trunks of birch. We show that over a long timescale encompassing soil aging and declining soil fertility the lichen flora can be negatively affected. However, these effects are heavily mediated by tree-scale factors. These changes in the lichen community may be of potential importance for ecosystem processes driven by lichen communities.
