Images depicting the display sequences of the four lizard species used in the present study (left) accompanied by the respective temporal structure profile graph (right; see text for details). In each image set, black arrows indicate the direction of movement. Motions such as head-bobs, limb waves and tail-flicks are usually repeated for several cycles. (a) The display sequence of A. muricatus starts with tail-flicks (A, B), followed by limb waves (C) and finishes with a whole body movement centred on a push-up (D). The temporal structure graph indicates a relatively intermittent movement throughout the sequence. (b) The display sequence of G. longirostris comprises a series of head bobbing (A) and limb waving (B), the final push up is followed by a forward body thrust/rise (C). The temporal structure graph indicates relatively constant movement but with several rapid changes in movements throughout the whole sequence. (c) The display of C. fordi is comparatively simple, and consists of rapid movement of the head up and down (head-bobbing, A). The temporal structure graph indicates a relatively continuous movement throughout the sequence. (d) The display sequence of C. decresii comprises with several limb waves (A) and a distinct raising of the tail with a coil at the distal end of the tail (B), it finishes with a forward body thrust with tail coiled (C). The temporal structure graph indicates relatively constant movement, featuring a gradual increase in the amount of body movement. Scale bars are provided for each species.
