  • Considering that knowledge of the biodiversity of a region is the first step toward its conservation and given the paucity of studies on aquatic insects from the Simandou streams, the diversity of these communities was assessed. Overall, 130 taxa belonging to 52 families and eight orders were recorded. Multivariate analyses gathered sites into three clusters in regard to aquatic insect composition. The highest taxonomic richness was registered in cluster that contained a mixture of upland and lowland sites, the latter remained minimally disturbed. These sites could be considered as reference sites in studies for assessing water quality. Generalized additive models (GAMs) calculated for the most frequent taxa showed that water temperature, dissolved oxygen, conductivity and pH were the incorporated explanatory variables.

  • Zooplankton community structure in YRE was studied after the Three Gorges Reservoir.

    Biomass and population density of zooplankton in YRE showed an increasing trend.

    The key factor affecting zooplankton community in YRE was bottom layer salinity.

    Long-term effects of TGR on zooplankton community in YRE need further investigation

    Three new Neotropical species of aquatic non-biting midges, Nilothauma canaima n. sp. from the Bolívar State, Venezuela, N. granma n. sp. from Granma Province, Cuba, and N. soka n. sp. from the Amazon State, Brazil are described and figured, and a key to the males of Nilothauma from the New World is given.

  • Mar Chiquita is a large salt lake of international importance because of its biodiversity. Key findings include its eutrophic condition and occurrence of a marked spring nutrient turnover followed by a clear water summer, despite lack of thermal stratification. Instead, lake shallowness and the subtropical climate appear as the main driving factors.

  • Photosynthetic performances of epilithic freshwater lichens representative of various submersion conditions were compared. Pigment composition, respiration rate, photosynthesis activity and PSII efficiency after thalli hydration/dehydration were determined, emphasizing large differences in photosynthetic traits of hyper- and sub-hydrophilic lichens. Our results reveal that performances of different freshwater lichen taxa are consistent with their habitat characteristics.
