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 5

Survivorship curves over 28 days for Mytella charruana in the salinity-temperature interaction experiments. (a) Juvenile, cold experiment (temperatures: 6, 9, and 20°C; salinities: 5, 22.5, and 40 ppt), (b) juvenile, warm experiment (temperatures: 20, 31, and 33°C; salinities: 9, 22.5, and 40 ppt), (c) adult, cold experiment (temperatures: 6, 9, and 20°C; salinities: 5, 22.5, and 40 ppt), and (d) adult, warm experiment (temperatures: 20, 31, and 33°C; salinities: 5, 22.5, and 40 ppt). Upper case letters indicate significant differences of among treatments using survival analysis. Dotted lines show the end of the 15-day temperature adjustment periods.
