资源简介:
Samples were collected in Kartchner Caverns, a carbonate cave in southern Arizona, USA. This cave is characterized by oligotrophic conditions, high humidity and elevated carbon dioxide levels. These characteristics make it a challenging environment for microbial survival. In 2006, Kartchner was designated a National Science Foundation Microbial Observatory for which a major goal is to determine the structure and diversity of cave microbes. This project addresses that goal by investigating the diversity and structure of fungal communities from mineral surfaces within the cave. A total of 24 speleothem and 24 rock wall swab samples were collected along a transect through the cave. Genomic DNA was extracted from each sample and the ITS1 region of the fungal rRNA gene was amplified and sequenced using 454 pyrosequencing.
