Development of long-term monitoring of Antarctic moss banks to recent climate changes
Original language description
The parameters of four moss banks in Argentine Islands were studied. Using unmanned aerial vehicle, we distinguished green and non-green color classes of moss in order to evaluate interannual changes. Spectral reflectance data were recorded and the normalized difference vegetation index (NDVI) values were calculated for each color class. Interannually, NDVI of green class cover increased, indicating a possible positive impact of integrate environmental factors. Laboratory measurements revealed a significant difference in chlorophyll content and shape of spectral reflectance curves (380–790 nm) for color classes of two dominant species of the moss communities, Polytrichum strictum and Sanionia georgicouncinata. The analysis of spectral indices revealed color-dependent differences in NDVI and other indices; photochemical reflectance index and NDVI were discovered to be the most sensitive to detect color classes. Chlorophyll fluorescence transients (OJIPs) and OJIP- derived parameters decreased in both species from green to non-green class due to the progressive decline in chlorophyll content and its ability to perform Photosystem II related photosynthetic processes. Thus, the green color class is healthy with a high chlorophyll content while the non-green is unhealthy, that can be used as an indicator of changes in the state of moss bank for the long-term monitoring.
