Green Sturgeon Distribution in the Pacific Ocean Estimated from Modeled Oceanographic Features and Migration Behavior
Figure 2
Plots depict the seasonal (red = summer, yellow = autumn, blue = winter, green = spring) marginal response of green sturgeon to each of the six model covariates while keeping all other environmental covariates at their average sample values. The axes indicate logistic output (i.e. probability of presence from 0 to 1). For the attraction covariates, the distance between spawning and overwintering grounds is equal to about 5000 cost units. Overwintering attraction is used in the autumn and winter when zero represents the overwintering location and spawning attraction, used in the summer and spring, indicates the mean location of the three spawning river mouths.
