Brine organisms and the question of habitat-specific adaptation
The question of adaptivity to extremely saline water environments is discussed, with attention given to the evolutionary performance of four common organisms including Cladonia skottsbergii, Penicillium notatum, Nostoc, and Dunaliella salina. Samples of each organism were collected and subjected to...
