translate English to French: It is suggested that this population of Cladonia rangiferina, which is markedly restriced to a position under the shade of Ledum shrubs, is protected there from the otherwise excessive heat load which occurs on the open Cladonia stellaris surface and which typically reaches 40 °C under full radiation conditions in summer.
Cette population de Cladonia rangiferina, qui se retrouve seulement à l'ombre d'arbustes de Ledum, y est protégée de la chaleur excessive rencontrée aux endroits ouverts à Cladonia stellaris et atteignant 40 °C dans les conditions estivales de radiation maximale.
