6/3/2023 0 Comments Primer 6 statistical softwareDistance-based Linear Model (DisTLM) analysis displayed six environmental variables showing significant relationships with the phytoplankton abundance in the resemblance matrix ( p < 0.05). ![]() Statistical analysis showed seasonal phytoplankton assemblages differences indicating a biogeographical gradient. Despite the low Shannon–Wiener index ( H ′) diversity (0.10–1.54), pointing out the dominant density of Bacillariophyta resulted in high water quality. Bacillariophyta (diatoms) were most diverse with 22 taxa, comprised more than 90% of the total density. A total of 51 taxa of phytoplankton belonging to six phyla were identified. Multivariate statistical analyses were carried out to define the abiotic variables influencing phytoplankton community composition. ![]() Sampling was conducted seasonally at five stations in the lake. ![]() Seasonal variations of phytoplankton abundance, species composition, and their interaction with environmental parameters were investigated in the Azad Dam Lake, in the West of Iran during 2015–2016.
