Table 2. Sensitivity of the recruitment model to variation in the density and survival of blue crab early life stages in marsh edge habitat. The first value of r (the rate of population change) was used in simulating a 10% hardened shoreline scenario. Percentages refer to the actual values used in the model. Density, D (%) Survival, S1 (%) Rate of population change, r 100 100 −0.045 50 100 −0.031 100 50 −0.028 50 50 −0.020 150 100 −0.054 100 150 −0.052 150 150 −0.064
