Article Synopsis
- The study examined planktonic ciliate communities in the Damietta region of the Nile Delta between May and June 2019, across 25 different sites with varying environmental conditions.
- A total of 32 ciliate taxa were identified, with six dominant species, mainly consisting of 21 tintinnids and 11 aloricate ciliates; their abundance and diversity showed clear spatial variations linked to salinity levels.
- The research highlights that ciliates can serve as effective bioindicators of environmental stress, as their communities responded quickly to changes in factors like salinity, chlorophyll-a, and nutrient levels.
The relationship between the protozoan communities and environmental variables was studied in the Nile River to evaluate their potential as water quality indicators. Protozoans were sampled monthly at six sampling sites in the Nile's Damietta Branch across a spatial gradient of environmental conditions during a 1-year cycle (February 2016-January 2017). The Protozoa community was comprised of 54 species belonging to six main heterotrophic Protozoa phyla.

A total of 32 water quality parameters were monitored at six sampling sites for 12 months from February 2016 to January 2017. Higher values of chemical oxygen demand (COD), biological oxygen demand (BOD), heavy metals, and nutrients were observed upstream.
