Results of permutational ANOVAs on the routine metabolic rate (RMR) measured in <i>T</i>. <i>mitchelli</i>, <i>T</i>. <i>pearsei</i> and <i>T</i>. <i>dzilamensis</i> at four moments (T₁, T₂, T₃ and T₄) after being exposed to either a moderate or an extreme salinity challenge.

Control RMR were measured in individuals of each species at their native salinity and compared among species. See descriptions in the text for references to the time of exposure and water salinity used to challenge each species. The pseudo-F and p values for each source of variation is given together with the results of post hoc comparisons of mean RMR values every time the main terms “Species”, “Time” or the interaction term were significant; different letters represent mean values that were statistically distinguishable (p < 0.05).
