Fig. 3From: Body size, swimming speed, or thermal sensitivity? Predator-imposed selection on amphibian larvaeNonlinear bivariate selection differentials. Nonlinear bivariate selection differentials (C i,j) for (a) maximum swimming velocity (U max) and total length (TL), and (b) U max and thermal sensitivity of U max (Q 10) in newt larvae subjected to predator-imposed selection episodes and controls.
