Antarctica plays a central role in regulating global climatic and oceanographic patterns and
is an integral part of global climate change discussions. The functioning of Antarctica's …

This review compiles principal data on Antarctic cynobacteria published in recent decades
and focuses on the diversity, environmental adaptations, and ecotypes of these …

Cryogenian strata of the Windermere Supergroup were deposited in tectonically active
basins throughout the North American Cordillera from Alaska to Mexico. The Windermere …

Clues to the evolutionary steps producing innovations in oxygenic photosynthesis may be
preserved in the genomes of organisms phylogenetically placed between non …

The earliest branching cyanobacterium, Gloeobacter, exhibits a number of ancestral traits
including the lack of thylakoids. It occurs epilithically in microbial mats, both subaerially and …

The undulating ice of the McMurdo Ice Shelf, Southern Victoria Land, supports one of the
largest networks of ice-based, multiyear meltwater pond habitats in Antarctica, where …

The Antarctic terrestrial macrobiota are highly endemic and biogeographically structured,
but whether this also holds true for microbial groups remains poorly understood. We studied …

Cyanobacteria in polar environments face environmental challenges, including cold
temperatures and extreme light seasonality with small diurnal variation, which has …

We explore the major characteristics of habitable environments on ocean worlds and how
we can study them using Earth analogs and autonomous instrumentation. Earth analogs for …

Photosynthetic Cyanobacteria and their descendants are the only known organisms capable
of oxygenic photosynthesis. Their metabolism permanently changed the Earth's surface and …
