Spectral characteristics of bryophyte carpet and mat subformation showing a vitality-dependent color pattern: Comparison for two distant regions of maritime Antarctica
Spectral characteristics of the bryophyte carpet and mat subformation on Nelson Island (South Shetlands Islands) and Galindez Island (Argentine Islands, Graham Coast) were analyzed using spectral reflectance characteristics. A set of 9 specific reflectance indices were calculated and compared betwee...
