ABSTRACT The development of cascaded reservoirs significantly alters the thermal regime river basins, impacting ecosystems. However, our understanding distribution water temperature in basins under high‐intensity hydropower conditions remains limited. In this study, we analyzed historical data and monitored present Wujiang River to assess effects cascade reservoir on fish. results revealed that with regulation capacity exhibited vertical stratification, leading a noticeable difference between surface downstream water, which turn caused fluctuations longitudinal River. Reservoirs have greater impact compared air temperature, elevation, discharge. critical (CT) threshold was reached mid‐late May early June different reservoirs, is within normal time range for fish spawning. accumulated (AT) value Pingzhai (PZ) did not reach required threshold, while AT other met earlier than spawning period continuous construction resulted significant reduction amplitude at Wulong hydrological station, intensifying delay This study systematically temporal spatial variations along mainstream provided direct assessment cumulative impacts ecosystem, offering invaluable insights into complex interplay dynamics.

Dam construction alters river hydrology, influencing the temporal and spatial heterogeneity of fish communities. This study utilized environmental DNA (eDNA) sequencing to analyze seasonal variations in communities Duliu River, Guizhou Province, assess impact hydrological regulation on biodiversity. High-throughput revealed that sequence reads were significantly higher dry season than wet (P < 0.05), while operational taxonomic unit (OTU) richness was greater season. A total 69 species (6 orders, 18 families) detected season, with only 23 matching historical records. eDNA identified an additional 46 species, primarily from order Cypriniformes. In 82 (7 17 recorded, including 44 not found data. Cypriniformes dominated both seasons, comprising 94% community 82% Spatial analysis using principal coordinates (PCoA) indicated significant differences among sections (PC1 = 65.2% season; 83.65% season). Beta diversity (NMDS) confirmed variation 0.05). highlights ecological dam underscores need for conservation strategies protect biodiversity regulated mountain rivers.

Fish diversity, an important indicator of aquatic ecosystem health, is declining due to water pollution, overfishing, climate change, and invasive species. Effective surveying monitoring are required protect fish diversity. Here, a high-sensitivity environmental DNA (eDNA) metabarcoding technique was used investigate diversity in the Danjiang River, Shaanxi Province, China. In total, 59 species were identified eight orders, 19 families, 40 genera. Cypriniformes Perciformes main groups survey area, while Cyprinidae accounted for 50.85% total Rhinogobius similis (19%), Hemibarbus umbrifer (11%), Gnathopogon herzensteini (10%), Triplophysa stewarti (8%), Zacco platypus (7%) dominant Eight rare two exotic identified. Combined with analysis historical data, richness using eDNA significantly higher than that captured ground cages. Temperature, pH, oxidation-reduction potential factors affect spatial distribution communities. These results suggest could be new tool broad application prospects; however, local databases must improved. This study provides theoretical data methodological reference protecting managing Qinling Mountains.
