Figure 2 | Physiological changes of A. erythraeaover time under different diets and treatments. (A) Respiration rate. The significance test for respiration rate was a t-test between the toxic group and the non-toxic group on the same day. (B) Ingestion rate. The field group represents copepods that have not been cultured in the laboratory. The significance test for ingestion rate is a t-test comparing the toxic/non-toxic group with the field group. (*p < 0.05; **p < 0.01; ***p < 0.001). (C) The non-toxic and toxic groups represent copepods fed exclusively with P. brasiliana and P. cuspidata , respectively. The Non-toxic+Anti and Toxic+Anti groups received the same algal diet with the addition of antibiotics. The hungry group consists of copepods that were not provided with an algal supply.
