Summary: In temperate shallow lakes, submerged macrophytes enhance zooplankton grazing and maintain a clear-water state. However, the role of macrophytes for zooplankton and their grazing potential in tropical lakes remains unclear. Our study in a tropical lake in China found that the dominance of copepods differed between basins, with cyclopoids dominating in the algal basin and calanoids in the macrophyte basins. The biomass ratios of calanoid:copepod and zooplankton:phytoplankton were higher in the macrophyte basins. Our results suggest that restoration measures involving macrophyte transplantation and fish removal can reduce fish predation and maintain clear-water state in tropical lakes, although top-down control may be weaker compared to temperate lakes.

Summary: The uptake and transformation of arsenic by living organisms can affect its distribution and biogeochemical cycles in the environment. This study investigated the bioaccumulation and speciation of arsenic in phytoplankton and zooplankton from soda lakes in the Brazilian Pantanal wetland. The results showed that the accumulation and accumulation factors of arsenic varied depending on the lake typology and season.

Summary: During the MERITE-HIPPOCAMPE campaign in the Mediterranean Sea, plankton samples were collected from 10 stations from the French coast to the Gulf of Gabe`s. The study found that the sources of carbon and nutrients in plankton vary depending on the coast and offshore area, and the size and nutritional content of plankton increase with size. The results also highlight spatial variations in the trophic structure of plankton size-fractions, which can contribute to the assessment of plankton as a biological pump of contaminants.

Summary: This study found that climate change and food web structure can impact the significant clear-water phase in lakes, with effects varying among different metrics. Higher water temperature leads to earlier start and peak dates of the clear-water phase, while the proportion of D. pulicaria affects all clear-water phase metrics, and high Bythotrephes density delays the start date of the clear-water phase.

Summary: In this study, widespread field surveys were conducted to identify traditional building practices in Himachal Pradesh, India. The surveys led to the identification of Kath-kunni, Thathara, Drystone, and Rammed earthen buildings. These practices were studied, classified, and sketched to analyze their siting, architectural and structural features, soil conditions, and foundations. Qualitative seismic vulnerability assessments were conducted to determine the earthquake-resilient and vulnerable features of these traditional buildings.

Summary: Many continental saline lakes are affected by increasing salinity and anthropogenic eutrophication, which have negative impacts on ecosystem functioning and water quality. The interactive effects of salinity and eutrophication vary depending on the size and depth of the lakes. Deep stratified lakes tend to have better water quality, while small shallow lakes are more vulnerable to the joint effect of salinity increase and eutrophication.

Summary: This study investigated the impact of grazing alien fish, Protosalanx chinensis, on the ecological equilibrium of lake plankton communities. The results showed that the stocking of P. chinensis did not deplete zooplankton resources and did not significantly affect biodiversity. However, there was a weakened correlation between phytoplankton and zooplankton in the lake where P. chinensis was stocked, indicating some effects on the ecological equilibrium. Long-term successive investigations are recommended for sustainable resource utilization and maintaining biological balance.

Summary: This study analyzed the distribution of potentially toxic trace elements in sediments and plankton from two small mesotrophic lakes impacted by volcanic activity. The composition of volcanic ashes in the lakes affected the trace element concentrations in surface sediments. The size and community structure of planktonic organisms played a significant role in trace element accumulation, with higher concentrations in microplankton. This study contributes to the limited knowledge of trace elements in freshwater ecosystems impacted by volcanic activity.

Summary: This study investigated the protective role of naringenin (NG) against cadmium chloride (CdCl2) toxicity in Labeo rohita. Exposure to CdCl2 for 15 and 30 days induced adaptive mechanisms, but on the 60th day, oxidative damage was observed. Oral administration of NG restored altered levels of antioxidants and enzymes, suggesting a protective role against Cd-induced oxidative insult.

Summary: Aquaculture and fisheries are important sectors that face the challenge of pathogenic diseases, particularly parasitic diseases like argulosis. Indian major carp species such as Labeo rohita are often affected by the parasitic species Argulus siamensis. While progress has been made with therapeutic chemicals and synthetic drugs, effective vaccines and drugs are still lacking. Therefore, there is a need for efficient, cost-effective, and eco-friendly control measures for argulosis.

Summary: This study investigates the primary productivity and trophic status of Rewalsar, Kuntbhyog, and Prashar lakes in the Western Himalayas. Seasonal variations in gross primary productivity (GPP), net primary productivity (NPP), respiration (R), and the NPP/R ratio were studied and compared with hydrobiological factors. Factors such as temperature, light, nutrients, and chlorophyll a were found to be accountable for high productivity. The trophic state indices calculated using Nygaard's method confirmed that Rewalsar and Kuntbhyog lakes were eutrophic, while Prashar Lake was oligo-eutrophic. Bioindicators of trophic status were determined based on the presence, absence, frequency, and abundance of different organisms recorded during the study.
