Variation of bacterial 16S rRNA gene sequences from different GSL adult Artemia samples. Percent abundance of a sequence was calculated by dividing the number of clones with that sequence in the season being analyzed by the total number of all clones from that season. Only contigs that were constructed from five or more total clones were included in the analysis. The genus that each sequence most closely matched is shown for reference. ABC1 was only present in the Spring 2007/DWR3 sample.
