Table 1 Model inputs and output metrics for the four species regional populations each under three different mortality scenarios. Columns three and four show the starting abundance and growth rate distributions, distributions denoted by \([\cdot ]\). Entries in parentheses contain the 5, 50, and 95% quantiles of simulations in the given year. Columns five and six contain the ending abundance distribution and the 20-year cumulative growth rate. Columns seven and eight contain the relative abundance difference and absolute growth rate difference at the end of the simulation period between the baseline and both mortality scenarios
