Effects of Soil Quality Enhancement on Pollinator-Plant Interactions

Both biotic and abiotic factors can affect soil quality, which can significantly impact plant growth, productivity, and resistance to pests. However, the effects of soil quality on the interactions of plants with beneficial arthropods, such as pollinators, have not been extensively examined. We studied the effects of vermicompost (earthworm compost, VC) soil amendment on behavioral and physiological responses of pollinators to flowers and floral resources, using cucumbers, Cucumis sativus, as our model system. Results from experiments conducted over three field seasons demonstrated that, in at least two out of three years, VC amendment significantly increased visit length, while reducing the time to first discovery. Bumblebee (Bombus impatiens) workers that fed on flowers from VC-amended plants had significantly larger and more active ovaries, a measure of nutritional quality. Pollen fractions of flowers from VC-grown plants had higher protein compared to those of plants grown in chemically fertilized potting soil. Nectar sugar content also tended to be higher in flowers from VC-grown plants, but differences were not statistically significant. In conclusion, soil quality enhancement, as achieved with VC amendment in this study, can significantly affect plant-pollinator interactions and directly influences pollinator nutrition and overall performance

The role of innovation adoption and circular economy readiness on the environmental sustainability: moderating impact of organizational support

Environmental sustainability is currently the most critical demand on a global scale, and it may be reached through innovation and a circular economy. This component demands the aim of policymakers and researchers. Therefore, this study investigates the effect of innovation adoption and circular economy readiness on Peru's environmental sustainability. The research also examines the moderating effect of organizational support on innovation adoption, preparation for the circular economy, and environmental sustainability in Peru. Using questionnaires, the researchers collected and evaluated the data using smart PLS. The results demonstrated a positive relationship between innovation adoption, circular economy readiness, and environmental sustainability in Peru. The results also demonstrated that organizational support moderates’ innovation uptake, preparation for the circular economy, and environmental sustainability in Peru. The research aids policymakers in formulating environmental sustainability strategies based on innovation uptake and circular economy preparedness.Campus Chimbot
