For these reasons, microbiologists have been drawn to Antarctica for decades. However, our understanding of which microbes thrive in Antarctic soils and how they to do so remains limited. To help resolve these knowledge gaps, we analyzed a collection of 200 archived Antarctic soils&amp;mdash;from Livingston Island on the Antarctic Peninsula to Cape Hallett in northern Victoria Land. We analyzed the prokaryotic and fungal communities in these soils using both cultivation-independent marker gene sequencing and cultivation-dependent approaches (microbial isolation), paired with extensive soil geochemical analyses. Our cultivation-independent analyses indicate that colder, saltier, and drier soils harbor less diverse communities of bacteria and fungi, distinct from those found in soils with less challenging conditions. We also built a culture collection from a subset of these soils that encompasses more than 50 bacterial and fungal genera, including cold-tolerant organisms, such as &amp;lt;i&amp;gt;Cryobacterium&amp;lt;/i&amp;gt; and &amp;lt;i&amp;gt;Cryomyces&amp;lt;/i&amp;gt;. By directly comparing the diversity of our cultured isolates against our cultivation-independent data, we show that many of the more abundant Antarctic taxa are not readily cultivated and highlight bacterial and fungal taxa that should be the focus of future cultivation efforts. Together, we hope that our collection of isolates, the comprehensive data compiled from the cultivation-independent analyses, and our geochemical analyses will serve as a community resource to accelerate the study of Antarctic soil microbes.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Childress, Mary K.</style></author><author><style face="normal" font="default" size="100%">Dragone, Nicholas B.</style></author><author><style face="normal" font="default" size="100%">Young, Benjamin D.</style></author><author><style face="normal" font="default" size="100%">Adams, Byron J.</style></author><author><style face="normal" font="default" size="100%">Noah Fierer</style></author><author><style face="normal" font="default" size="100%">Quandt, C.

This study describes three new species of &lt;i&gt;Pseudogymnoascus&lt;/i&gt;&amp;mdash;&lt;i&gt;P. russus&lt;/i&gt; sp. nov., &lt;i&gt;P. irelandiae&lt;/i&gt; sp. nov., and &lt;i&gt;P. ramosus&lt;/i&gt; sp. nov.&amp;mdash;isolated from Antarctic soils. These species represent the first &lt;i&gt;Pseudogymnoascus&lt;/i&gt; taxa to be formally described from Antarctic soil samples, expanding our understanding of fungal biodiversity in this extreme environment. Microscopic descriptions of asexual structures from living cultures, along with measurements of cultural characteristics and growth on various media types at different temperatures, identify three distinct new species. In addition, phylogenetic analyses based on five gene regions (ITS, LSU, MCM7, RPB2, TEF1) and whole-genome proteomes place these new species within three distinct previously described clades: &lt;i&gt;P. irelandiae&lt;/i&gt; in clade K, &lt;i&gt;P. ramosus&lt;/i&gt; in clade Q, and &lt;i&gt;P. russus&lt;/i&gt; in clade B. These results provide further evidence of the extensive undescribed diversity of &lt;i&gt;Pseudogymnoascus&lt;/i&gt; in high-latitude soils. This study contributes to the growing body of knowledge on Antarctic mycology and the broader ecology of psychrophilic and psychrotolerant fungi.&lt;/p&gt;</style></abstract></record></records></xml>
