Altitude and fungal diversity influence the structure of Antarctic cryptoendolithic Bacteria communities
Summary Endolithic growth within rocks is a critical adaptation of microbes living in harsh environments where exposure to extreme temperature, radiation, and desiccation limits the predominant life forms, such as in the ice‐free regions of Continental Antarctica. The microbial diversity of the endo...

Summary Endolithic growth within rocks is a critical adaptation of microbes living in harsh environments where exposure to extreme temperature, radiation, and desiccation limits the predominant life forms, such as in the ice‐free regions of Continental Antarctica.

In this work, diversity and composition of bacterial assemblages in the cryptoendolithic lichen‐dominated communities of Victoria Land (Continental Antarctica) were explored using a high‐throughput metabarcoding approach, targeting the V4 region of 16S rDNA. Rocks were collected in 12 different localities (from 14 different sites), along a gradient ranging from 1000 to 3300 m a.s.l. and at a sea distance ranging from 29 to 96 km.
