<p>Distribution of the three classes of feeding behaviour (invertebrate eaters in purple, omnivores in orange and diatom eaters in deep green). Stacked bar chart showing the proportions of the various feeding behaviour classes by species and zone type in <b>A</b>), by season for each syntopic zone in <b>B</b>). Probability of GutVac (<i>y</i>-axis) as predicted by the multinomial model as a function of size in <b>C)</b> in which the <i>X</i>-axis corresponds to body size in cm, and we can read for example the longer specimens are more omnivor than herbivor.</p
