Microbial communities of the Arctic Ocean are poorly characterized in comparison to other
aquatic environments as to their horizontal, vertical, and temporal turnover. Yet, recent …

The Arctic is warming–fast. Microbes in the Arctic play pivotal roles in feedbacks that magnify
the impacts of Arctic change. Understanding the genome evolution, diversity and dynamics …

One of the most prominent manifestations of climate change is the changing Arctic sea-ice
regime with a reduction in the summer sea-ice extent and a shift from thicker, perennial …

Microorganisms inhabiting saline environments are an interesting ecological model for the
study of the adaptation of organisms to extreme living conditions and constitute a precious …

Subzero hypersaline brines are liquid microbial habitats within otherwise frozen
environments, where concentrated dissolved salts prevent freezing. Such extreme …

The Arctic is warming 2–3 times faster than the global average, leading to a decrease in
Arctic sea ice extent, thickness, and associated changes in sea ice structure. These changes …

Hypersaline aqueous environments at subzero temperatures are known to be inhabited by
microorganisms, yet information on community structure in subzero brines is very limited …

Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the
last decades than during the past 800,000 years. Brackish brine (fed by meltwater inside the …

Antarctic sea-ice bacterial community composition and dynamics in various developmental
stages were investigated during the austral winter in 2013. Thick snow cover likely insulated …

The thawing of snow and sea ice produces distinctive melt ponds on the surface of the Arctic
sea ice, which covers a significant portion of the surface sea ice during summer. Melt-pond …
