TL;DR: It is reported that UV light exposure, especially in the UV-C range, can stimulate phenolic-antioxidant production in aplanospores of C. nivalis effecting biochemical pathways related to proline metabolism.

TL;DR: G6PDH specific activity, the first committed step of the pentose phosphate pathway, was negatively associated with shoot growth and proline concentrations, and antioxidant protection factor in pea shoots was also stimulated by AR-10 extracts.

TL;DR: In the Tioga Pass area (upper LeeVining Creek watershed) of the Sierra Nevada (California), snow algae were prevalent in the early summers of 1993 and 1994 as discussed by the authors.

TL;DR: Both of these bogs have pH environments close to the lowest limit for methanogenesis, and small differences in pH values can have a large impact on both the rate of methane production and the rates of methane release to the atmosphere.

TL;DR: This is the first report of snow algae from the Sierra Nevada mountains of Spain and from the Afro-alpine environment and other microbes observed in snow samples include bacteria, fungi,heterotrophic euglenids, diatoms, nematodes, and heterotrophic mastigotes.
