Figure 2.

Strongylocentrotus purpuratus larvae exhibit phenotypic plasticity. Marginal posterior means and 95% credible intervals (error bars) of parameters estimated in linear mixed models for spicule (a) and body (b) length of larvae reared in either non-upwelling (N) or upwelling (U) developmental environments. Parents were either conditioned in the non-upwelling (circles) or upwelling (triangles) environments (black solid lines connect treatment means from the same parental environment). Plotted colours and letters refer to treatment combinations as detailed in figure 1. (Online version in colour.)
