Harmful substances in the wastewater negatively affect ecological balance by reducing dissolved oxygen concentration. High phosphorus and nitrogen compounds discharged into surface water resources may cause to eutrophication, due increased algal growth. In this study, Elodea densa (Egeria), Lemna minor (Duckweed), Micranthemum micranthemoides (Micra), Pistia (Water Lettuce), Ceratophyllum demer...

Background and aims – Epiphytic diatoms are excellent bio-indicators of the present past ecological condition aquatic ecosystems. In order to reconstruct diatom history evaluate its diversity in Democratic Republic Congo, epiphytic were sampled from herbarium specimens plants deposited at National Herbarium Congo Yangambi (YBI) Meise Botanic Garden (BR).Material methods YBI, nine belonging Nymp...

The potential of aquatic plants to accumulate Cs may be notable importance in the environmental monitoring radioactive wastes. This study aimed evaluate accumulation Cs-133 by freshwater macrophytes Bacopa amplexicaulis, Elodea densa, Ceratophyllum submersum, and Limnobium laevigantum after a 10-day incubation period with CsCl (1–1000 μM). partitioning other elements, including 21 metals, such ...

Abstract Both non-rooted submerged vegetation dominated by coontail ( Ceratophyllum demersum) and floating duckweed Lemna gibba ) can maintain their stable dominance in small ponds channels. We examined the competitive interactions between them how sustain its state against plants a range of nutrient concentrations. Coontail were co-cultured static semi-static microcosm experiments, impact on n...

Combined use of in situ passivation and macrophytes is a valuable technology that exerts remarkable effects on aquatic systems. However, the effectiveness ecological functions this combined for macrophytes-dominated eutrophic (MDE) lakes with organophosphorus-controlled internal phosphorus (P) loading were poorly understood. In study, simulation experiments performed to study combination La-mod...

Artificial light at night (ALAN) is recognized as one of the major anthropogenic pollutants jeopardizing biodiversity a global scale. Few studies have focused on impacts nocturnal freshwater ecosystems despite their increasing exposure to pollution worldwide due human activities along rivers or lakes. By modifying metabolism, disruption natural regime could modify leaf palatability and affect p...
