“…Pearson correlation coefficient indicated that several environmental variables influence the zooplankton abundance and distribution, in particular water temperature, total alkalinity, total hardness, ammonia, total nitrogen, nitrite and nitrate. Similar observation was previously obtained by Bhanja et al (2014) Abdel Mola and Ahmed (2015) Abdulwahab and Rabee (2015), and Abdul et al (2016).…”

This study was carried out in Nozha hydrodrome, Alexandria, to assess the impact of physico-chemical parameters upon zooplankton community structure and diversity during the period from December 2015 to November. 2016. The results indicated that there were significant monthly variations in physical and chemical characteristics, such as water temperature, pH, dissolved oxygen, total alkalinity, total hardness, nitrite, nitrate, total nitrogen,orthophosphate and total phosphorus. Zooplankton were represented by fifteen genera belong to four groups. Rotifera constituted the main dominant group contributing 82.59% of the total zooplankton, followed by Copepoda (12.33%), Cladocera (3.886%) and Ostracoda (1.22%). The highest density of zooplankton was recorded during January (mean 2504.5 org/ l), while the lowest was found in July (mean 44.25 org/l).The data pointed out that the most effective water variables on composition and distribution of zooplankton were water temperature, total alkalinity, total hardness, ammonia, nitrite, nitrate and total nitrogen. The low value of Shannon diversity index, high value of some water parameters and dominance of pollution tolerant forms of zooplankton revealed that the hydrodrome is suffering from organic pollution.

“…A similar number of rotifer taxa to that in the Bolina River, i.e. 12 taxa, occurred in a tropical coastal estuary in Nigeria (mean salinity 537.17 mS cm À1 ) (Abdul et al, 2016). In the strongly naturally saline Nile River Estuary (salinity up to 40 PSU), El-Tohamy et al (2018) reported a lower number of rotifer taxa in the planktonic samples (six taxa) than in the Bolina River; however, the average density of the planktonic rotifers was much lower in the Bolina River than that in the Nile River Estuary.…”

The research was carried out in the Bolina River, which is the most anthropogenically saline river in Europe, from 2017 to 2018. This river flows through the highly industrialised and urbanised part of Upper Silesia (Poland). The aims of our survey were to analyse the structure of the rotifer communities and to determine the most important environmental factors that have a significant impact on their structure in a river under the influence of underground salty mine water discharge. According to a canonical correspondence analysis (CCA), the rotifer communities in the Bolina River are affected by electrical conductivity, the temperature of the water and the concentration of phosphates. An increase in the electrical conductivity (salinity) in the lower course, which was the result of salty mine water discharge into the Bolina River, was reflected by a decrease in the median density, the number of rotifer taxa and the Shannon–Wiener index H′. The Bolina River is a unique habitat for halophilic rotifers as well as a site of the occurrence of rotifers that can also develop in winter.

“…The Ganga river sustains a variety of aquatic biodiversity such as phytoplankton, zooplankton, benthic organisms, and fish fauna (Sharma et al 2018). In the food chain, zooplankton plays a major role by influencing the productivity and functioning of the aquatic ecosystem and affects the nutrient dynamics process from plankton to benthos (Geetha Madhav and Kondalarao 2004;Keister et al 2012;Varadharajan and Soundarapandian 2013;Waidi et al 2016). The distribution, composition, and abundance of zooplankton depends upon the condition of the aquatic environment (Govindasamy and Kannan 1996;Waidi et al 2016).…”

The spatial and temporal variation in the distribution, abundance and assemblage structure of zooplankton were examined in a mining-impacted stretch of river Ganga. The collection of samples has been done from three different sampling zones such as Z1 (Chandi Bridge Ghat) as reference zone, Z2 (Shyampur), and Z3 (Bisanpur) as mining-intruded area from May 2017 to April 2018. During the analysis, twenty-eight species of zooplankton kindred to four groups mainly Rotifera (ten species), Protozoa (five species), Cladocera (eight species), and Copepoda (five species) were identified. In the course of analysis, it was observed that Rotifera were dominant (43.49 %) followed by Cladocera (19.58 %), Protozoa (18.31 %), and Copepoda (18.62 %). The results showed that the distribution and abundance of zooplankton fluctuated more at Z1 (reference zone) as compared with Z2 and Z3 (mining-intruded zones). The diversity indices also indicated the higher richness, abundance, and evenness of zooplankton ranging from 3.145 to 3.180 at Z1, 3.081 to 3.129 at Z2, and 3.130 to 3.175 at Z3. The canonical correspondence analysis (CCA) showed positive and negative correlation between the zooplankton and water quality of the river Ganga. The present study shows that the anthropogenic activities such as river bed mining disturbed the water quality through enhancing the turbidity and nutrients load in the aquatic system. However, these changes in water quality significantly affected the distribution and abundance of zooplankton.
