Plants and landscape in the Vestfold Hills, Antarcticaiscussed in relation to the length of time that particular areas have been exposed as a result of ice retreat. With increasing time of exposure, plant diversity and abundance rise but subsequently fall sharply as conditions become more arid, saline, or both. This temporal sequence can be explained b

The . spp. grew well at −2°C, but not −5°C in hypersaline waters. The concentration of H.S had no apparent effect on the de
