The rare biosphere, the low abundant microbial populations, is suggested to be a conserved way of life. Here we conducted molecular survey methanogenic archaea in environment targeting mcrA gene order test if general concepts associated with structure bacterial biosphere also apply single functional groups. Similar what known about communities, contribution methanogens alpha diversity much larger than Bray-Curtis measures. Moreover, similar core group harbored by and communities suggests sources environmental controls both Among different levels rarity, conditionally taxa largely account for overall community dynamics likely enter dominant under favorable conditions. In addition, observed positive correlation between production methane when were taken into account. This supports concept that increasing biodiversity enhances ecological function. composition associations allow us conclude rarity
