Table 5. Summary statistics for modeled scenarios of the effects of habitat change on Gulf of Mexico blue crab landings. Means are for the last five years of simulations, with 1000 iterations/yr (N = 5000). Statistics are back-transformed from approximately log-normal distributions, i.e., geometric means and errors. SE = bootstrap standard error of the mean.
