While no photosynthetic activity was detected for dry crusts, hydrated crusts showed significantly higher F-v/F-m values than dry crusts. A significant correlation between the PRI and F-v/F-m was found in moss- and lichen-dominated crusts, and the determination coefficients were higher than those between the NDVI and F-v/F-m. %$ 126 ; 068
