“…CCA showed that WT and the TN and TP contents were the key environmental factors that affected the distribution of the macrobenthic community in the upper and middle reaches of the HRB. WT is considered to be the key natural variable affecting changes in the water environment, and the level of WT directly or indirectly interferes with the physical and chemical characteristics of water bodies and aquatic biological structures (Yuan et al 2014). Cooper et al (2007) found that WT was an important parameter affecting the community structure of macrobenthos.…”

To clarify the characteristics of macrobenthic assemblages and their response to the aquatic environment in the upper and middle reaches of the Heihe River, water quality, sediments and macrobenthos measurements were conducted in the summers of 2018 and 2019. The results showed that 50 species of macrobenthos were identified, belonging to 3 phyla, 7 classes, 15 orders and 32 families, mainly arthropods (37 species) and mollusks (11 species). Argyroneta aquatica, Chlaznius sp., dragonfly nymphs, Palaemon modestus, Radix auricularia, Cyraulus albus and Suecinea sp. were the dominant species in the whole study region; most of these are pollution-tolerant and moderately tolerant species. The macrobenthos density and biomass ranged from 10 to 577 ind./m2 and from 0.0907 to 50.0562 g/m2, respectively, showing high spatial heterogeneity. Predators were the main functional feeding group. One-way analysis of variance clarified that Margalef's index and the Shannon–Wiener index differed significantly among the spatial areas (P < 0.05). Canonical correspondence analysis showed that the spatial heterogeneity of the macrobenthos was affected by the water temperature and the total nitrogen and total phosphorus in sediments (P < 0.05).

“…Yangzong Lake is a freshwater deep lake on the Yunnan Plateau, belonging to the Nanpan River System in the Pearl River Basin. The average annual temperature is 14.5°C, with an average precipitation of 963.5mm (Yuan et al, 2014). The average water level is 1770.6m, the lake has an average length of 12km north to south and an average width of 2.7km east to west.…”

Bacteria are critical components of lake ecosystems, and understanding the characteristics of bacterial community structure and diversity indices is of significant importance for the analysis and management of lake ecology. In this study, overlying water samples were collected from Yangzong Lake in May, June, and July 2021. High-throughput sequencing and statistical analysis were employed to investigate the relationships between physicochemical factors, bacterial community structure, and diversity in the overlying water of Yangzong Lake. The results showed significant differences in oxidation-reduction potential among the sampling points. The order of oxidation-reduction potential was as follows: Yangzong DAHE > Yangzong Lake South > Yangzong Lake Middle > Yangzong Lake North, while other physicochemical factors exhibited minor differences. The number of OTUs and bacterial alpha diversity index in the overlying water of Yangzong Lake Middle were higher than those in Yangzong Lake North, Yangzong Lake South, and Yangzong DAHE. The dominant bacterial phyla in the overlying water were Actinobacteriota, Bacteroidota, and Proteobacteria. Actinobacteriota had the highest relative abundance of 34.63% in Yangzong Lake North, while Bacteroidota had the highest relative abundance of 33.79% in Yangzong Lake South, and Proteobacteria had the highest relative abundance of 27.29% in Yangzong Lake Middle. The dominant genera were hgcI_clade, CL500-29_marine_group, and Flavobacterium. Among them, hgcI_clade had the highest relative abundance of 37.56% in Yangzong Lake North, CL500-29_marine_group had the highest relative abundance of 35.22% in Yangzong Lake South, and Flavobacterium had the highest relative abundance of 42.02% in Yangzong Lake Middle. Correlation analysis revealed significant correlations between Campilobacterota at the phylum level and dissolved oxygen (DO) and total phosphorus (TP). At the genus level, Flavobacterium, Limnohabitans, and Pseudarcicella showed significant correlations with DO and TP.
