Ecology and distribution of Dermatocarpon( Verrucariaceae, Ascomycota) in the catchment areas of two Bulgarian rivers
Abstract Temperature preferences and small-scale distribution patterns of four Dermatocarpon taxa in the catchment areas of two Bulgarian rivers were analyzed. Taxa with an overall alpine or arctic-alpine distribution were restricted to microhabitats with the lowest water and rock surface temperatur...

Abstract Temperature preferences and small-scale distribution patterns of four Dermatocarpon taxa in the catchment areas of two Bulgarian rivers were analyzed.
