The molecular diversity of Archaea in a bat guano pile in Cave Domica (Slovakia), temperate cave ecosystem with significant bat colony (about 1600 individuals), was examined. The guano pile was created mainly by an activity of the Mediterranean horseshoe bat (Rhinolophus euryale) and provides a source of organic carbon and other nutrients in the oligotrophic subsurface ecosystem. The upper and the basal parts of guano surface were sampled where the latter one had higher pH and higher admixture of limestone bedrock and increased colonization of invertebrates. The relative proportion of Archaea determined using CARD-FISH in both parts was 3.5-3.9% (the basal and upper part, respectively). The archaeal community was dominated by non-thermophilic Crenarchaeota (99% of clones).
