Environmentally triggered shifts in steelhead migration behavior and consequences for survival in the mid-Columbia River
Fig 6
The combined modeled effects for temperature and arrival date at Bonneville Dam for the probability of delay (pDelay) for each population group. Data used to inform models are plotted over the predicted surfaces with black circles representing designated fast migrants and white circles representing delayed migrants. Contour lines are spaced at probabilities of 0.1. Vertical dashed lines represent median arrival dates at Bonneville Dam by population groups.
