Description	It is well established that spectral reflectance and photosynthetic parameters are dependent on actual hydration of a thallus, its relative water content (RWC) in autotrophic poikilohydric organisms. In Nostoc sp. from polar regions, these parameters have been investigated (see e.g. Moudrá et Barták 2009, Kvíderová et al. 2011, Trnková et al. 2014, Trnková et Barták 2015). In this study, we focused on a detailed analysis of NDVI and PRI spectral indices, and effective quantum yield of photosynthetic processes in photosystem II in desiccating Nostoc sp.
