Various environmental factors play a role in the formation and collapse of Microcystis blooms. This study investigates impact heavy rainfall on cyanobacterial abundance, microbial community composition, functional dynamics Nakdong River, South Korea, during typical exceptionally rainy years. The results reveal distinct responses to variations, particularly dominance physicochemical characteristics. In 2020, characterized by unprecedented from mid-July August, blooms were interrupted significantly, exhibiting lower cell densities decreased water temperature, compared normal bloom patterns 2019. Moreover, composition varied, with increases Gammaproteobacteria notably genera Limnohabitans Fluviicola. These alterations conditions bacterial similar those post-bloom period late September It shows that summer leads changes factors, consequently causing shifts communities akin observed autumn-specific also accompany functions, primarily involved degradation organic matter such as amino acids, fatty terpenoids, which are assumed have been released due significant cyanobacteria. Our demonstrate early induces subsequently their autumn, leading earlier breakdown

Prokaryotic and eukaryotic periphyton responses to warming, nutrient enrichment and small omnivorous fish: a shallow lake mesocosms experiment

Environmental Research, Год журнала: 2025, Номер unknown, С. 120942 - 120942

Global change stressors, including climate warming, eutrophication, and small-sized omnivorous fish, may exert interactive effects on the food webs functioning of shallow lakes. Periphyton plays a central role in primary production nutrient cycling lakes but constitutes complex community composed eukaryotes prokaryotes that exhibit different responses to multiple environmental stressors with implications for projections global We analyzed enrichment, small fish their interactions eukaryotic prokaryotic periphyton structures lake mesocosms. performed 16S 18S rRNA high-throughput sequencing elucidate effect abovementioned stressors. found warming promoted periphytic alpha diversity network complexity, multi-tolerant genera becoming dominating (e.g. Spirosomaceae Azospirillaceae). Contrastingly, enrichment led reduced complexity stability, weak disruption structure. Small were major drivers changes periphyton, facilitating increasing biomarker diversity. Omnivorous grazing pressure mainly through selective zooplankton, contributing structural stability functional diversity, especially proliferation biomarkers. Nutrient counteracted positive while concerted action high TN TP concentrations accelerated negative development The co-occurrence three pressures ultimately resulted biodiversity structure weakened connectivity environment. Our study provided new insights into understanding response ecological functions freshwater change.

Comprehensive Evaluation and Coupled Coordinated Development Study of Water–Economic–Ecological Systems in the Five Northwestern Provinces of China

Water, Год журнала: 2023, Номер 15(24), С. 4260 - 4260

Опубликована: Дек. 12, 2023

The five northwestern provinces face numerous challenges in sustainable development, particularly water scarcity, economic imbalances, and ecological degradation. This study aims to deeply assess the region’s resource conditions, current status of health ecosystem while exploring relationships coupling mechanisms among them. Using obstacle model, research analyzes primary barriers affecting these three significant factors region. further reveals a continually improving trend coordinated development within water–economic–ecological system China, indicating that usage per ten thousand GDP is obstacle. enriches our understanding China’s provides theoretical foundation for achieving development.
