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 2

Survivorship curves of Mytella charruana for temperature experiments. Shell lengths: 20–54 mm. Capital letters correspond to the experimental treatments presented in Table 1(a). (a) Cold experiment (temperatures: 6, 9, 11, and 13°C); (b) warm experiment (temperatures: 20, 31, and 36°C); and (c) warm experiment (temperatures: 20, 23, 28, and 31°C). Upper case letters indicate significant differences in survivorship () among temperature treatments. Dotted lines show the end of the 15-day temperature adjustment periods.
