  • a BacI and BacIV designate the bacterial 16S rRNA gene clone libraries obtained from the northern shore of the lake from either the upper sediment zone I or the deeper sediment zone IV. ArcI and ArcIV designate the archaeal 16S rRNA gene clone libraries obtained from the northern shore of the lake from either the upper sediment zone I or the deeper sediment zone IV.

  • b ACE, abundance-based coverage estimator.

  • c ICE, incidence-based coverage estimator.
