Habitat suitability in relation to mesozooplankton density (ROMS_zz2) at depth for two different turtles (a, 3; and b, 8). Thick black line represents the median response, dashed lines represent the uncertainty in the parameter estimate. See text for details on the computation of habitat suitability. The effect of uncertainty on our understanding is striking, with parameter estimates being narrow for turtle 3, but broad for turtle 8. Turtle 8 had the highest median parameter value, as well as the highest uncertainty around parameter estimates. Note the change in the y axis.
