Figure 1 - Time-distribution of active behavioural categories (feeding and/or exploring) of Armadillidium vulgare from all groups in observational days. Legend: CON – control, MAR – marker-marked, POL – polish-marked, grey triangles mark night-time activity, black line running from the centre of the diagram to the outer edge marks mean time of activity and the arcs extending to either side represent the 95% confidence limits.
