Étude des lichens saxicoles de la steppe semi-aride de Djebel Zdimm (Nord-Est de l’Algérie)

In the high plains of setif, calcareous rock, the main component of Djebel Zdimm, has contributed to the installation of very diverse saxicolous lichenic vegetation which is of great biological and phytogeographic interest because of its presence in a semi-arid steppe with a dry season extended for...
