Figure 1. Survival and development of antibiotic-treated and control groups of Nitocra spinipes.

(A) Survivorship, %; (B) percentage of copepodites (%Copepodites); and (C) copepod developmental index (DI). All data are shown as median and range observed at the termination of experiments, i.e., day 13 for ciprofloxacin (Cipro) and sulfamethoxazole (Sulf), and day 11 for trimethoprim (Trim) treatments, whereas statistical comparisons are based on the Box Cox transformed data; * (p<0.05) and *** (p<0.001) denote significant differences from the respective controls.
