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 backtransformed from approximately lognormal distributions, i.e., geometric means and errors. SE = bootstrap standard error of the mean.
