Impact of anthropogenic activities on the biodiversity of macrobenthos and benthic ecological quality in the mudflats of Hwangdo Island, South Korea: field surveys and remote sensing assessments

Published: Feb. 5, 2025

Introduction As coastal urbanization progresses, anthropogenic activities have significantly impacted mudflats. In South Korea, land reclamation and aquaculture drastically altered mudflat ecosystems. Methods our study, we utilized five remote sensing indices to assess the impact of on Hwangdo Island. We supplemented this with field surveys evaluate macrobenthic biodiversity benthic ecological quality, investigating their relationship activities. Results discussion Spearman’s correlation analysis revealed that terrestrial quality influences biodiversity. The abundance predominant species, Pirenella sp., was primarily influenced by normalized differential build-up bare soil index (NDBSI). Furthermore, biota-environment matching (BIO-ENV) analysis, distance-based multivariate for a linear model (DisLM), redundancy (dbRDA) all pinpointed NDBSI as factor impacting communities in mudflats Seasonal changes were mainly attributed variations area resulting from agricultural Overall, Island are indirectly affected Moreover, study offers fresh perspective conservation Island’s provides critical references Korean government crafting implementing protection policies.

Effects of nitrogen fertilization on the fate of high-risk antibiotic resistance genes in reclaimed water-irrigated soil and plants

Environment International, Journal Year: 2024, Volume and Issue: 190, P. 108834 - 108834

Published: June 18, 2024

High-risk antibiotic resistance genes (ARGs) in reclaimed water-irrigated soil pose a potential threat to ecosystem and human health. Inorganic fertilization - including with nitrogen, key ingredient agricultural production may affect the ARG profile soil. However, little is known about nitrogen fertilization's influence on ARGs profiles soil-plant system. This study investigated effects of different fertilizer types (CO(NH

Mitigating the transfer risk of antibiotic resistance genes from fertilized soil to cherry radish during the application of insect fertilizer

Environment International, Journal Year: 2025, Volume and Issue: 199, P. 109510 - 109510

Published: May 1, 2025

The transfer of antibiotic resistance genes (ARGs) from fertilized soil to vegetables, particularly those consumed raw, causes significant public health risks through the food chain. Black soldier fly larvae can efficiently convert animal manure into organic fertilizer with reduced resistance. This study utilized metagenomic sequencing investigate fields treated control (COF), black (BOF), and no fertilizer, aim assessing ARGs cherry radish. results indicated that BOF significantly richness abundance in both radish compared COF, reducing 13 ARG subtypes a 27.6% decrease Moreover, positive correlation was observed between mobile genetic elements (MGEs) virulence factors (VFs) ARGs, treatment resulting relative reduction 32.8% 29.1%, respectively. complexity networks involving MGEs, VFs, microbial communities 54.2%, 32.3%, lower, respectively, than COF treatment. Further analysis metagenomic-assembled genomes (MAGs) revealed co-occurrence VFs radish, indicating presence potential pathogenic antibiotic-resistant bacteria (PARB). Notably, these PARB radishes decreased by 45.6% COF. These findings underscore efficacy insect mitigating highlighting significance sustainable agricultural practices managing environmental associated ARGs.
