Figures 1-2 from: Freire CA, Rios LP, Giareta EP, Castellano GC (2017) Oxygen consumption remains stable while ammonia excretion is reduced upon short time exposure to high salinity in Macrobrachium acanthurus (Caridae: Palaemonidae), a recent freshwater colonizer. Zoologia 34: 1-9. https://doi.org/10.3897/zoologia.34.e20173

Figures 1-2 - Initial (circles) and final (squares) levels of dissolved oxygen in the water (1) and lactate concentration in the hemolymph (2) of M. acanthurus exposed to salinities 0 (control), 10, 20, and 30 psu for 4 (white symbols) and 8 hours (black symbols). Values near to the lines represent oxygen consumption (mean ± std dev) as a percentage of the initial oxygen concentration (considered 100%, as a reference value). (#) Initial and final levels of dissolved oxygen are different. There were no significant differences between salinities or times (4 and 8 hours) for oxygen consumption and lactate concentration.
