Effect of SVG, flow velocity, and their interaction on the transition matrix for grayling with associated 95% confidence interval (CI) (grey bars). Every cluster of four graphs should be read as: top-left) probability of a behavioural switch from behaviour 1 to behaviour 1, top-right) the chance of switching from behaviour 1 to behaviour 2, bottom-left) switching from behaviour 2 to behaviour 1, and bottom-right) switching from behaviour 2 to behaviour 2. SVG had an effect, though CI is relatively wide (A1). SVG relative angle had no effect (A2). Flow velocity had no effect for either absolute values (B1) or relative angle (B2). In the interaction only SVG had an effect (C1)
