Antarctic lichens have been used as indicators of climate change for decades, but only a few
species have been studied. We assessed the photosynthetic performance of the fruticose …

In this study, we investigated responses of the Photochemical Reflectance Index (PRI), and
Normalized Difference Vegetation Index (NDVI) to gradual dehydration of several Antarctic …

Lichens are symbiotic organisms that are well adapted to desiccation/rehydration cycles.
Over the last decades, the physiological background of their photosynthetic response …

Climate warming in the Antarctic tundra will affect locally dominant cryptogams. Being
adapted to low temperatures and freezing, little is known about the response of the polar …

Lichens survive harsh weather of Antarctica as well as of other hostile environments
worldwide. Therefore, this investigation is important to understand the evolution of life on …

In this study, we investigated the effects of low temperature on the fast chlorophyll
fluorescence transient (OJIP) and OJIP-derived parameters in chlorolichen Dermatocarpon …

Lichens are successful colonizers in extreme environments worldwide, and they are
considered to have played an important role during the evolution of life. Here, we have used …

This study explores and compares the limits for photosynthesis in subzero temperatures of
six Antarctic lichens: Sphaerophorus globosus, Caloplaca regalis, Umbilicaria antarctica …

Diurnal courses of photosystem II (PS II) activity of Xanthoria elegans were continuously
monitored using a novel technique of chlorophyll fluorescence imaging in the field (maritime …

Chlorophyll fluorescence is an effective tool for investigating characteristics of any
photosynthesizing organisms and its responses due to different stressors. Here, we have …
