Fig. 1 in Calcium fluxes in Hoplosternum littorale (tamoatá) exposed to different types of Amazonian waters

Fig. 1. Net Ca2+ fluxes of Hoplosternum littorale exposed to well water as a function of time after transfer from tanks of ion-poor well water. Data expressed as mean ± SEM. Positive values indicate net influxes and negative values net effluxes. AC - after change. Asterisks (*) indicate significantly different from 2 h by Kruskall-Wallis ANOVA and Mann-Whitney test (P <0.05).
