This study provided a zooplankton species list from 180 lakes in northeastern Brazil and showed that species distribution, richness and composition vary according to biome (Atlantic Forest or Caatinga), the lake origin (natural or man-made lakes), and the lake habitat (pelagic or littoral).

Fish biodiversity on Hau River was for the first time thoroughly investigated. One endangered and six vulnerable species were scarcely recorded, only 1-2 times a year among 176 species caught by 5 fishing gears. Trawl and trammel nets are destructive gears but commonly used in fishing. CPUE was found low and declining as in other areas of the Mekong River.

Mapping the spatio-temporal distribution for Chl-a, SDT, and WST with remotely sensed data would be helpful for management of freshwater ecosystems (here the wetland). According to the results of this study, large changes in these parameters were observed in the Choghakhor wetland during the period 1985-2017 and reflect the ecological conditions in the wetland. Considering that this first study with a new approach to the region, it can be used as a comprehensive guideline for remote monitoring as a viable tool for monitoring wetlands.

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.

The occurrence of M. aeruginosa bloom in two freshwater ponds along central Kerala has been addressed along with the variations in the hydrobiological characteristics of the ecosystem during bloom and non-bloom conditions of the species. Histological studies highlight hepatotoxicity of M. aeruginosa signifying regular monitoring of bloom events in these ecosystems.

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.

This study examines the effects of bottom-up (physical-chemical) and top-down (predation) factors on the phytoplankton functional groups in a eutrophic lake. The study revealed that the bottom-up effects of physical-chemical variables on some phytoplankton functional groups was stronger than the top-down effects of zooplankton. The study further showed that zooplankton functional groups were positively correlated with phytoplankton biomass implying that the top-down control of phytoplankton by the zooplankton in Lake Hulun is not strong enough to produce a negative effect. These finding serve as a basis for identifying how phytoplankton dynamics are influenced, which have implications for developing sustainable management strategies and conserving services of Lake Hulun and other eutrophic fresh water lakes.

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.

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.
