  abstract = {{T}he {C}arnoul{\`e}s mine is an extreme environment located in the {S}outh of {F}rance. {I}t is an unusual ecosystem due to its acidic p{H} (2-3), high concentration of heavy metals, iron, and sulfate, but mainly due to its very high concentration of arsenic (up to 10 g {L}-1 in the tailing stock pore water, and 100-350 mg {L}-1 in {R}eigous {C}reek, which collects the acid mine drainage). {H}ere, we present a survey of the archaeal community in the sediment and its temporal variation using a culture-independent approach by cloning of 16{S} r{RNA} encoding genes. {T}he taxonomic affiliation of {A}rchaea showed a low degree of biodiversity with two different phyla: {E}uryarchaeota and {T}haumarchaeota. {T}he archaeal community varied in composition and richness throughout the sampling campaigns. {M}any sequences were phylogenetically related to the order {T}hermoplasmatales represented by aerobic or facultatively anaerobic, thermoacidophilic autotrophic or heterotrophic organisms like the organotrophic genus {T}hermogymnomonas. {S}ome members of {T}hermoplasmatales can also derive energy from sulfur/iron oxidation or reduction. {W}e also found microorganisms affiliated with methanogenic {A}rchaea ({M}ethanomassiliicoccus luminyensis), which are involved in the carbon cycle. {S}ome sequences affiliated with ammonia oxidizers, involved in the first and rate-limiting step in nitrification, a key process in the nitrogen cycle were also observed, including {C}andidatus {N}itrososphaera viennensis and {C}andidatus nitrosopumilus sp. {T}hese results suggest that {A}rchaea may be important players in the {R}eigous sediments through their participation in the biochemical cycles of elements, including those of carbon and nitrogen.},
