“…Fv/Fm, representing the maximum photochemical efficiency of PSII, changes minimally under non-stress conditions and is a key indicator of the extent to which plant photosynthetic light reactions are inhibited under various stresses [35,36]. In PSII reaction centers, absorbed light energy mainly contributes to three types of transformation and dissipation, including Y(II), the effective quantum yield [37]. The interaction between V. natans and B. aeruginosa is evident in the removal of algae attached to leaves.…”

This study aims to assess the ecological restoration effects of Vallisneria natans in a multitrophic level ecosystem. The water-purification effects of two hierarchical configuration modes of V. natans-Bellamya aeruginosa and V. natans-B. aeruginosa-Hyriopsis cumingii were studied. Results show that a V. natans and B. aeruginosa configuration ratio of 15:2 stabilizes water quality at Grade IV (TN ≤ 1.5 mg/L, TP ≤ 0.3 mg/L), and increasing B. aeruginosa density significantly reduces total phosphorus. The V. natans, B. aeruginosa, and H. cumingii configuration at 15:2:10 stabilizes water at Grade III (TN ≤ 1.0 mg/L, TP ≤ 0.2 mg/L), with a positive correlation between H. cumingii density and chlorophyll-a removal. Furthermore, the filtration and biocycling actions of B. aeruginosa (snails) and H. cumingii (mussels) significantly reduce levels of Total Nitrogen (TN), Total Phosphorus (TP), and Ammonium (NH4+-N) in water, thus enhancing the self-purification capacity of the water bodies. However, the bioturbation effect of H. cumingii can temporarily increase phosphorus release from sediments, leading to a short-term rise in TP concentration in the water. Overall, the study concludes that multitrophic level ecosystems are effective in purifying water quality and offer significant ecological restoration benefits. This research provides crucial data support for future construction and ecological restoration projects involving multitrophic level approaches in China’s rivers and lakes.

The cotton plant suffers from many pests and due to its economic importance, the use of efficient but ecologically friendly pesticides is highly desirable. The insecticide Sumi-Alpha with active compound Esfenvalerate is widely used for cotton treatment in Uzbekistan. This insecticide is considered as moderately hazardous for different organisms of ecosystems, while more collected data and relevant research is a necessity for judgement of their safety and/or potential risk. Therefore, a comparative analysis of cotton leaves was performed to study the protein profile changes upon treatment with this insecticide. Our data showed elevated accumulation of fructose bisphosphate aldolase and degradation of RuBisCo in the treated tissue. Besides, a protein belonging to P-loop containing nucleoside triphosphate hydrolases superfamily exerted lower accumulation. Our results indicate that the applied pyrethroid pesticide possibly can affect photosynthesis performance and cause accumulation of simple saccharides which in turn might contribute to enhanced colonisation of sucking insects. Further molecular research on Sumi-Alpha effects on cotton is necessary for its safer use in agricultural practice.
