Figure 3.
Panel (A) shows the proportion of sub-adult Delta Smelt in the fresher tank versus salinity in the higher salinity tank. The solid line represents the top-ranked (intercept model) and the dashed lines are the 95% CI. Panel (B) shows the same plot as panel (A) but with means calculated for temperature bins. Panel (C) shows a scatterplot of the difference in salinity between the two tanks by salinity in the higher salinity tank. Panel (D) shows the mean difference in salinity between the two tanks by salinity in the higher salinity tank. An average salinity difference of 2.2 ppt was maintained between the two tanks (SD = 0.9 ppt). Note that the blue, horizontal line indicates no preference (i.e., a y-intercept of 0.5).
