Abstract
Thalli of four saxicolous lichens on slate rock fragments were transplanted from rock surafces to horizontal boards and then to south-east-facing and north-west-facing rock surfaces. The radial growth rate of Physcia orbicularis and Parmelia conspersa thalli declined after transplatation to north-west-facing rock surfaces and was unchanged after transplantation to south-east-facing rock surfaces cmpared with growth rates on the boards. The radial growth rate of P. glabratula ssp. fuliginosa thalli declined after transplantation to south-east-facing rock surfaces and was unchanged after transplantation to north-west-facing rock surfaces compared with grwoth rate on the boards. The radial growth rate of P. saxatilis thalli was similar on the horizontal boards, south-east-facing and north-west-facing rock surfaces. These results are dsicussed in relation to the aspect distribution of the four lichens in South Gwynedd, Wales.
