“…The CCA ordination analysis revealed that the considerable variations in different mesozooplankton groups among sampling stations were significantly correlated with the variations of temperature, conductivity, and nitrate concentrations. This confirms with the observations in other areas, where the water temperature was a keystone element in the seasonal dynamics of mesozooplankton (Jerling and Weerts, 2018;Nakajima et al, 2017), and may regulate most ecological mechanisms in temperate areas (Sellami et al, 2010). As mentioned by El-Tohamy (2018a), the study area receives relatively high anthropogenic disturbance, directly or indirectly resulting in high values of nutrients and conductivity.…”

River was studied to assess the impacts caused by human activities. The sampling was done monthly at seven stations during October 2013-September 2014. A plankton ring net with 180 µm mesh size was used to avoid the bias toward the collection of smaller mesozooplanktons such as rotifers and copepod larvae. Thirty-six mesozooplankton taxa were recorded. Cladocera was the most abundant group (41.6%), followed by Copepods (29.9%), Rotifera (14.8%), and Ostracoda (13.2%). The decrease in rotifers density in favor of copepods and cladocerans in the ROT:CLA:COP ratio suggesting an increase in the area eutrophication. According to SIMPER analysis, the most important taxa were Bosmina longirostris, Ceriodaphnia reticulate, Moina micrura, Acanthocyclops americanus, Brachionus calyciflorus, and Candona subgibba. Multivariate analysis indicated that the variations in species distribution were associated with environmental factors, especially water temperature, conductivity, and nitrate. The degree of anthropogenic disturbance determines the quality and quantity of plankton in the study area. Consequently, the discharged post-cooling waters should be controlled to protect zooplankton fauna and in consequence the planktivorous fish of the study area.

“…Zooplankton species are commonly utilized as bioindicators for environmental changes since they respond quickly to environmental pollution as a whole community (Whitman et al, 2004;Altindag et al, 2009;Kaya et al, 2010;Sellami et al, 2010). Zooplankton as indicators of ecological circumstances have importance due to their position in the food web; they reflect the top-down regulators (fish), bottom-up factors (phytoplankton), and benthic status, and thus they supply information about the relative importance of top-down and bottom-up control and their effects on water transparency (Zhao et al, 2008;Jeppesen et al, 2011).…”

“…Such pattern could be explained by the difference in the abundance of mesozooplankton and in community structure, as every species, particular the dominant ones, has its own response to the surrounding conditions. The water temperature was accounted as essential factor in the dynamics of zooplankton, as it may regulate most ecological mechanisms in temperate areas (Sellami et al 2010). Our findings revealed that water temperature had significant negative correlation with the diversity index, but it was not correlated with mesozooplankton count.…”
