Figure 4.

Variation in the form of the density-dependent mortality function of oystercatchers given various population densities of Manila clams (0 clams m⁻², filled circles; 5 clams m⁻², open circles; 10 clams m⁻², filled squares; 20 clams m⁻², open squares; 40 clams m⁻², filled triangles). Each data point depicts the mean predicted over-winter mortality arising from 10 replicate simulations of each scenario. The variation between replicate simulations was so small that the 95% CIs cannot be presented given the size of the symbols.
