Gradient of algal and cyanobacterial assemblages in a temporary lake with melting water at Solorina Valley, James Ross Island, Antarctica
The aim of presented study is to contribute to species list of algae, cyanobacteria and diatoms from moist localities of James Ross Island, Solorina Valley (63° 53' S, 57° 48' W) in particular. In 2012, samples of microbiological mats were taken from a bottom of shallow depression close to...
