Galanthus reginae-olgae in particular Greece and former Yugoslavia. It is found in relatively dry, shady woodland. "Galanthus reginae-olgae" is cultivated as an ornamental bulbous plant, particularly the autumn-flowering variants. In cultivation, it requires a warmer and sunnier position than most other "Galanthus" species. The cultivar 'Cambridge', originating from the Cambridge University Botanic Garden, has large green markings on the inner tepals. Galanthus reginae-olgae Galanthus reginae-olgae is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans (parts of Greece and the former Yugoslavia). Some variants produce their pendant white flowers in autumn, others in
Chlamydomonas nivalis optimal position in the snow for moisture content, light, and temperature. When in the immotile cyst stage, the "C. nivalis" cells must depend on the flow of meltwater to move it by chance to a favourable area. The temperatures in which this species can survive in ranges from below 0 °C to just above 20 °C. Growth is slow when temperatures are below 5 °C. At 5-15 °C the growth of "C. nivalis" cells can outperform the growth of C. reinhardtii cells. Both species grow at the same rate at 20-25 °C. The growth of "C. nivalis" is suppressed when
