Small and shallow water bodies are particularly sensitive to adverse conditions connected with anthropogenic eutrophication. As model systems, ponds a good object for ecological research monitoring of global environmental changes. We examined cyanobacteria along other groups algae versus zooplankton abiotic characteristics in 51 aquatic ecosystems exposed pressure (from natural forest highly disturbed field ponds) 3 distinct trophic groups: meso-, eu- hypertrophic.

This study develops a quantitative polymerase chain reaction (qPCR) method to detect four prevalent algal genera, Pseudanabaena, Cylindrospermopsis, Cryptomonas, and Limnothrix─in nine drinking water reservoirs in Zhuhai, China. We examined the correlation between abundance both quality parameters reservoir characteristics. Cryptomonas was most abundant, with average levels at 6.76 ± 2.20 log10 copies/L, while Pseudanabaena showed lowest 4.93 2.50 copies/L. Although nutrient substances minimal impact, abundances exhibited active substantial responses characteristics including scale, retention time, supply source, hydrological seasons. High were significantly associated large-scale reservoirs, long river-fed wet seasons (p < 0.05). Redundancy analysis indicated that account for 51.5% of variation abundance. demonstrates effectiveness qPCR monitoring dynamics highlights significant role influencing blooms.
