Abstract: This paper examines the links between moisture, epilithic lichens, rock surface temperatures and weathering. Field and laboratory experiments were conducted in order to investigate the combined effect of surface wetness and Verrucaria nigrescens (an epilithic lichen) on limestone temperature fluctuations. Exposure blocks with and without a lichen cover were subjected to short-term temperature fluctuations and two types of moisture events: artificial showers (8 ml rainfall) and larger storms …
