Lichen-induced biomodification of calcareous surfaces : Bioprotection versus biodeterioration

Auteur(s) et Affiliation(s)



Description :
From research in the last 2 decades, this paper reviews lichen-induced biomodification, with particular emphasis on bioprotection of calcareous surfaces. A series of conceptual models is proposed to illustrate the idea over short (single lichen lifespan) and long (multiple lichen lifespans) timescales. The models suggest that the microscale biogeomorphological system of lichen-rock interaction is underpinned by non-linear dynamical system theory as it exhibits dynamical instability and is consequently difficult to predict over a long timescale. Dominance by biodeterioration or bioprotection may be altered by changes in lichen species or in environmental conditions over time.
