| Description
| - U dvou druhů zelených vláknitých řas, Raphidonema nivale izolované ze sněhu a R. sempervirens izolované z půdy v Arktidě (souostroví Svalbard), byla sledována závislost morfologických znaků na měnících se ekologických podmínkách (teplota a ozáření). U zkoumaných druhů bylo zjištěno, že se liší ve svých ekologických nárocích a že R. nivale, v minulosti považovaná za sněžný druh, pravděpodobně běžně roste v půdě. R. nivale je v průběhu katabatických větrů dopravován do sněžných polí, kde přežívá jen po omezené období. (cs)
- Two Arctic species of Raphidonema, a weakly filamentous green alga, were compared on the basis of their growth and morphology response to varied environmental factors. The strain of R. nivale was isolated from snow and R. sempervirens from soil collected in Svalbard. Morphological variability was evaluated in both strains, with emphasis laid on pleiomorphism of R. nivale. Growth characteristics in varied temperature and light were compared. Field observations were performed in the summer season 2003 at Werenskiöld glacier, southwest Spitsbergen. In both strains, temperature and light affects shape and size of cells, and in R. nivale also the number of cells in filament, probably by modifying growth and division rates. The strain of R. nivale grew best at 12°C and 200 ?mol.m-2.s-1, R. sempervirens at 18°C and 50 ?mol.m-2.s-1. In snow, R. nivale only appeared after strong wind had brought soil on the snow surface, and its concentrations decreased very rapidly. Cells of R. nivale in sn...
