Glaciers and ice sheets, like other biomes, occupy a significant area of the planet and
harbour biological communities with distinct interactions and feedbacks with their physical …

Snow or glacial algae are found on all continents, and most species are in the
Chlamydomonadales (Chlorophyta) and Zygnematales (Streptophyta). Other algal groups …

Cryopreservation is the storage of viable cells, tissues, organs and organisms at ultra-low
temperatures, usually in liquid nitrogen to a minimum temperature of− 196° C. The term …

Snow algae inhabit most of the cold regions worldwide, where long-lasting snow fields are
common. The ecophysiology of snow algae has been studied intensively in North America …

Melting snowfields in polar and alpine regions often exhibit a red and orange colouration
caused by microalgae. The diversity of these organisms is still poorly understood. We …

We have assessed the microbial ecology on the surface of Mittivakkat glacier in SE-
Greenland during the exceptional high melting season in July 2012 when the so far most …

Algae are important primary colonizers of snow and glacial ice, but hitherto little is known
about their ecology on Iceland's glaciers and ice caps. Due do the close proximity of active …

Distinct microbial habitats on glacial surfaces are dominated by snow and ice algae, which
are the critical players and the dominant primary colonisers and net producers during the …

Glacier and ice sheet surfaces host diverse communities of microorganisms whose activity
(or inactivity) influences biogeochemical cycles and ice melting. Supraglacial microbes …

All plant species reach a low temperature range limit when either low temperature extremes
exceed their freezing tolerance or when their metabolism becomes too restricted. In this …
