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.
