Depending on the increase in agricultural production, the use of pesticides has also increased worldwide. Imidacloprid is a neonicotinoid pesticide and one of the most widely used in the world. In this study, it was aimed to investigate the histopathological changes in zebrafish ovary and testis tissue caused by imidacloprid, which pollutes the aquatic ecosystem in various ways. It has been shown that imidacloprid causes histopathological changes in the gonads by causing deterioration in the structure of reproductive cells.

The modified Carlson trophic status index, Shannon diversity index, and phytoplankton functional group index were used to assess ecological condition of a drinking water reservoir in central China. Applying all three indices together yielded a comprehensive ecological assessment, which could do so for other similar reservoirs.

One key finding of this work is that the studied population seems to be well adapted to its harsh semi-arid environment. Even in an intermittent river, Sylviocarcinus pictus, apparently, manages to keep a continuous breeding pattern, also documented for species from temperate regions of the globe.

Amphibious plant species successfully thrivein water and on dry land. Outstanding phenotypic plasticity at structural and functional levelsenables optimal performance in contrasting environments.They have great potential to colonise aquatic ecosystemswherethe hydrological regime isaltered by climate changes.

Due to the recorded preference for higher water temperature, dragonfly larvae preferred tufa barriers, while they were mostly absent from headwaters of mountainous streams. Favorable microhabitats were inorganic substrates associated with lower current velocity, in contrast to mosses associated with the strongest current. These results represent an important contribution to the knowledge of dragonfly ecology in karstic lotic habitats.

Macrothrix paulensis group (Cladocera: Macrothricidae) includes 11 taxa. A basal section consists of 5 taxa which are both biogeographical and phylogenetic relicts and the crown group contains 6 taxa which are widely distributed in tropical lowlands, but no truly “Pantropical” taxa were found.

The study was intended to investigate faunal diversity of Cladocera in Subansiri flood plain wetlands. This is the first kind of study to document cladoceran fauna from these non-explored habitats.

There are many types of small waters in the Balkans. They are habitats for Chironomidae. Mountain rheocrenes are inhabited by cold-adapted midges. The fauna of springs in the river valleys is diverse. Midges living in the Skodra L.’ spring system prefer higher water temperatures and hard substrates.

The environmental factors altitude, salinity, hydroperiod and depth of water body affect the distribution of aquatic beetles in Northern Western Ghats, India. Some congeners showed different affinity to the altitude while some groups of different body forms co-occurred.
