Description
  • Hlavním cílem projektu bylo zjistit, zda jsou fototrofické mikroorganismy přenášené větrem a později uložené na ledovcových nebo sněhových polích. Hlavním výsledkem bylo zjištění, že se nepodařilo získat žádné kultivovatelné fototrofické mikroorganismy. Zároveň se však podařilo vykultivovat unikátní bakterie z aerosolu a sněhu Alp. Mnohem více heterotrofů bylo možno vykultivovat ze sněhu a ledu And a Alp, nežli ze vzorků z Antarktidy. Na základě těchto výsledků je možné oddělit dvě společenstav organismů. 1. Ubiquitní mikroorganismy a 2. organismy nacházející se jen ve specifických podmínkách %22isolovaných%22 chladných pouští. (cs)
  • Taxonomical and ecological analyses were performed on micro-autotrophs (cyanobacteria and algae together with remnants of diatom valves), micro-fungi (hyphae and spores), bacteria (rod, cocci and red clusters), yeast, and plant pollen extracted from various samples: Alps snow (Mt. Blank area), Andean snow (Illimani, Bolivia), Antarctic aerosol filters (Dumont d’Urville, Terre Adelie), and Antarctic inland ice (Terre Adelie). The most striking result of this study was the absence of culturable micro-autotrophs in all studied samples. However, an unusual culturable pigmented prokaryote was found in both alpine snow and aerosol samples. Analyses of many samples and proper statistical analyses (PCA, RDA- Monte Carlo permutation tests) showed that studied treatments highly significantly differ in both microbial community and biotic remnants composition F=9.33, p=0.001.
