The Increase of Insect Pest Population in Paddy Field Managed with an Ecological Approach using Refugia Plants and Biopesticides
Published 2024-06-01“…The analysis includes the species diversity index (Shannon-Winner), species evenness index, species richness index (Margalef), dominance index (Simpson) and similarity index (Bray-Curtis). The study obtained 2,687 individual insect pests in paddy fields with refugia and fobio and 1,761 individuals in paddy fields without refugia and fobio. …”

Three local plants adapt to ecological restoration of abandoned lead-zinc mines through assembly of rhizosphere bacterial communities
Published 2025-02-01“…IntroductionThe plant restoration and ecological restoration of lead-zinc mines are very important.MethodsIn this study, we used three local plants to carry out ecological restoration of abandoned lead–zinc mining areas and detected the adaptive mechanisms of soil bacterial diversity and function during the ecological restoration of lead–zinc mines through 16S rRNA sequencing.ResultsThe results revealed that lead-zinc mining significantly reduced the soil bacterial diversity, including the Shannon, Simpson, and observed species indices, whereas the planting of the three ecological restoration plants restored the soil microbial diversity to a certain extent, leading to increases in the Shannon index and Observed species indices. …”
