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.

Our study on trait-environment relationship of co-occurring water beetles in anthropogenic ponds revealed that submerged vegetation, odonate nymphs, calcium hardness, salinity and chironomid larvae affected body size, swimming traits and functional feeding groups of the beetles in assemblages.

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.

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.

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.

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.

In our study of the spawning behaviour of lake whitefish, we observed fish using a variety of habitat types during the spawning season, including a rocky spawning shoal, sandy substrates, and steeper slopes. Both sexes moved shallower at night and deeper during the day, with males moving more at night and females more during the day. This study could help inform stewardship efforts aimed at lake whitefish spawning habitat restoration and protection.
