Diversity and Composition of Methanotroph Communities in Caves

Abstract

Methane oxidizing microorganisms (methanotrophs) are ubiquitous in theenvironment and represent a major sink for the greenhouse gas methane (CH4). Recentstudies have demonstrated methanotrophs are abundant and contribute to CH4 dynamics in caves. However, very little is known about what controls the distribution andabundance of methanotrophs in subterranean ecosystems. Here, we report a survey ofsoils collected from . 20 caves in North America to elucidate the factors shaping cavemethanotroph communities. Using 16S rRNA sequencing, we recovered methanotrophsfrom nearly all (98%) of the samples, including cave sites where CH4 concentrationswere at or below detection limits (#0.3 ppmv).
