FIGURE 2. Observed accumulation of Synalpheus species in the gambarelloides group (thick black line); expected species accumulation curve (grey line) estimated using the bootstrap function in EstimateS (Colwell 2005); observed unique shrimp-sponge associations (thin black line, right y-axis); and observed accumulation of unique sponge host species (white circles) as a function of collection effort (number of unique sponge samples collected, x-axis).
