Synergistic Effects of Salinity and Temperature on the Survival of Two Nonnative Bivalve Molluscs, Perna viridis (Linnaeus 1758) and Mytella charruana (d’Orbigny 1846)

Figure 3

Survivorship curves over 28 days for Perna viridis in the temperature-salinity interaction experiments. (a) Juvenile, cold experiment (temperatures: 6, 9, and 20°C; salinities: 5, 20, and 36 ppt); (b) juvenile, warm experiment (temperatures: 20, 31, and 35°C; salinities: 5, 20, and 36 ppt); (c) adult, cold experiment (temperatures: 6, 9, and 20°C; salinities: 5, 20, and 35 ppt); and (d) adult, warm experiment (temperatures: 20, 31, and 35°C; salinities: 5, 20, and 37 ppt). Upper case letters indicate significant differences of among treatments using survivorship analysis. Dotted lines show the end of the 15-day temperature adjustment periods.
