Figure 8 in Do ship strikes threaten the recovery of endangered eastern North Pacific blue whales?
Figure 8. Results for the long-term approach to future status. Equilibrium abundance relative to carrying capacity is shown for Sobs ¼ 10 and a range of multipliers of current levels of 2013 vessels. The model was projected forward 100 yr for each posterior sample under a constant multiplier (x-axis value). Model trajectories are shown as filled gray areas representing the 0.95, 0.75, 0.5, 0.25, and 0.05 posterior percentiles. The probability that the population is depleted (i.e., below 60% of K) is shown as a curved line. The solid vertical line denotes the median ratio of vessels in 2050 to 2013, i.e., the multiplier in 2050 estimated by our vessel model.
Figure 7 in Do ship strikes threaten the recovery of endangered eastern North Pacific blue whales?
Figure 7. Results of the short-term approach to future status. Future ship strikes, abundances, and abundances relative to carrying capacity for Sobs ¼ 10 are shown for three mitiga2013 tion cases (columns). Model trajectories are shown as filled gray areas representing the 0.95, 0.75, 0.5, 0.25, and 0.05 posterior percentiles. "Status quo" means no additional mitigation, "mitigation" refers to halving the ship strikes after 2013, and "none" is a complete elimination of future ship strikes. The horizontal lines at 0.6 denote the level below which the population is considered depleted.

Figure 4. Posterior densities for the abundance relative to carrying capacity in 2013 for Sobs ¼ 10 (top) and Sobs ¼ 35 (bottom) and the two priors for r. The vertical line at 0.6 2013 2013 denotes the level below which the population is considered depleted.

Figure 6. Absolute abundance, the abundance estimates and anthropogenic mortalities for Sobs ¼ 10 and the two priors for r. The rectangles at the bottom denote total estimated mor2013 talities (median catches + median strikes) for each year. The five abundance estimates (points) are shown with their 95% confidence intervals (bars). Model trajectories are shown as filled gray areas representing the 0.95, 0.75, 0.5, 0.25, and 0.05 posterior percentiles.
