Rarefaction curves of high throughput sequencing of 16S rRNA (V2) and 18S rRNA (V9) hypervariable regions.
Figure 2.
Phytoplankton in Lake Gjersjøen from 1969 to 1989 detected by high throughput sequencing of 16S rRNA (a) and 18S rRNA (b) hypervariable regions.
Figure 3.
Phytoplankton occurrences in Lake Gjersjøen from 1969 to 1989, and comparison of genera/species numbers using high throughput sequencing of 16S rRNA gene and 18S rRNA gene and microscopy (a. at the species level; b. at the genus level).
The M:P stand for the ratio of total species/genus numbers detected by microscopy and HTS.
Figure 4.
Phytoplankton detected by high throughput sequencing of 16S rRNA gene and 18S rRNA gene and microscopy at the species level in Lake Gjersjøen.
The species which formed frequent blooms of toxigenic cyanobacteria in this lake were marked with “↑”.
