What is it about?
Rivers are dynamic systems that respond to various physicochemical characteristics. In this review, we focused on the most important physicochemical parameters that influenced zooplankton composition and diversity in the rivers, including water temperature, dissolved oxygen, biochemical oxygen demand, hydrogen ion concentration, electrical conductivity, salinity, total dissolved solids, total suspended solids, turbidity, total hardness, calcium, magnesium, total alkalinity, bicarbonate, phosphate, nitrate, sulphate, and water velocity. As well, we defined these environmental factors and determined the minimum and maximum values for each factor. In general, we can conclude that physicochemical factors that exceed standard values have a negative effect on zooplankton composition and diversity.

Why is it important?
The study aimed to (1) investigate the most important physicochemical parameters that influenced zooplankton composition and diversity in riverine systems. (2) Define each physicochemical factor and determine their allowable limits for aquatic life.
Perspectives
We can conclude that zooplankton composition and diversity in the riverine system are affected by physicochemical factors and hydrological regimes. When the values of these parameters cross the permissible limits, it significantly impacts both zooplankton composition and diversity. This study also highlighted discharge rates as the main factor that drives the structure of the zooplankton community and transports these organisms.
