“…Zooplankton behavioral parameters include swimming speed, hopping frequency, quiescence duration, vertical or horizontal distribution, turn number, turning angle, and thoracic limb activity. 23,83 Most of these parameters have been investigated with reference to antibiotics, particularly in Daphnia species (Figure 2B). Exposure to antibiotics typically reduces the swimming ability of zooplankton.…”

“…25 Additionally, swimming behavior is a widely used biomarker that links individual-level variables with community functions. For example, Wan et al 23 revealed that norfloxacin strengthens the positive effect of larval damselflies on C. vulgaris growth because larval damselflies more efficiently suppress grazer density due to weakened grazer swimming ability. These findings provide novel insights into the mechanisms by which norfloxacin affects aquatic food chains; they reveal the importance of zooplankton behavior in determining trophic cascades.…”

“…Zooplankton behavior is a sensitive biomarker of various environmental pollutants and disturbances; i.e., environmental pollutants can impact zooplankton behavior at contaminant concentrations much lower than traditional toxicological end points. , Therefore, swimming end points are frequently used in toxicology. Zooplankton behavioral parameters include swimming speed, hopping frequency, quiescence duration, vertical or horizontal distribution, turn number, turning angle, and thoracic limb activity. , Most of these parameters have been investigated with reference to antibiotics, particularly in Daphnia species (Figure B).…”

“…Planktonic organisms are primary producers that are sensitive to various environmental disturbances, including high nutrient levels, and toxic contaminants. − Changes in the structure and function of planktonic communities may have indirect but important effects on organisms at higher trophic levels . Thus, plankton can serve as early warning indicators of aquatic ecosystem health.…”

Antibiotic pollution has become one of the most challenging environmental issues in aquatic ecosystems, with adverse effects on planktonic organisms that occupy the base of the aquatic food chain. However, research regarding this topic has not been systematically reviewed, especially in terms of community-level responses. In this review, we provide an overview of current antibiotic pollution in aquatic environments worldwide. Then, we summarize recent studies concerning the responses of planktonic communities to antibiotics, ranging from individual- to community-level responses. Studies have shown that extremely high concentrations of antibiotics can directly harm the growth and survival of plankton; however, such concentrations are rarely found in natural freshwater. It is more likely that environmentally relevant concentrations of antibiotics will affect the physiological, morphological, and behavioral characteristics of planktonic organisms; influence interspecific interactions among plankton species via asymmetrical responses in species traits; and thus alter the structure and function of the entire planktonic ecosystem. This review highlights the importance of community analysis in revealing antibiotic toxicity. We also encourage the establishment of the causal relationships between impacts at multiple scales in the future for predicting the community-level consequences of antibiotics based on the currently available individual-level evidence.

“…Norfloxacin (NOR) is one of the most widely used fluoroquinolone antibiotics globally (Haque and Muneer 2007, Wan et al. 2020), and its concentration in naturel aquatic environments can reach the sub‐micrograms to a few milligrams per liter level (Xu et al. 2007, Li et al.…”

Cyanobacterial harmful algal blooms (cyanoHABs) in freshwater lakes across the globe are often combined with other stressors. Pharmaceutical pollution, especially antibiotics in water bodies, poses a potential hazard in aquatic ecosystems. However, how antibiotics influence the risk of cyanoHABs remains unclear. Here, we investigated the effects of norfloxacin (NOR), one of the most widely used antibiotics globally, to a bloom‐forming cyanobacterium (Microcystis aeruginosa) and a common green alga (Scenedesmus quadricauda), under both mono‐ and coculture conditions. Taxon‐specific responses to NOR were evaluated in monoculture. In addition, the growth rate and change in ratio of cyanobacteria to green algae when cocultured with exposure to NOR were determined. In monocultures of Microcystis, exposure to low concentrations of NOR resulted in decreases in biomass, chlorophyll a and soluble protein content, while superoxide anion content and superoxide dismutase activity increased. However, NOR at high concentration only slightly affected Scenedesmus. During the co‐culture trials of Microcystis and Scenedesmus, the 5 μg · L−1 NOR treatment increased the ratio of Microcystis to co‐cultured Scenedesmus by 47.2%. Meanwhile, although Scenedesmus growth was enhanced by 4.2% under NOR treatment in monoculture, it was conversely inhibited by 63.4% and 38.2% when co‐cultured with Microcystis with and without NOR, respectively. Our results indicate that antibiotic pollution has a potential risk to enhance the perniciousness of cyanoHABs by disturbing interspecific interaction between cyanobacteria and green algae. These results reinforce the need for scientists and managers to consider the influence of xenobiotics in shaping the outcome of interactions among multiple species in aquatic ecosystems.
