Analysis of push-up and lateral compression behaviors
Push-ups were registered in 42.8% (9/21) of the tournaments. We registered 416 push-ups in 39 independent push-up events with a mean ± SE 10.67 ± 0.72 push-ups per event (range = 1-23). These were performed by the lizards at a mean distance ± SE of 26.82 ± 4.58 mm between opponents. In push-up events, 33.3% (13/39) were followed by an aggressive response of the opponent male (see a list of behaviors and their classification in Table 1).
Lateral compressions were registered in 23.8% (5/21) of the trials. We registered 88 events of lateral compression with a mean ± SE duration of 22.12 ± 7.18 seconds. The mean distance ± SE between opponents was 10.61 ± 3 mm. These took place during aggressive interactions because 76.1% (67/88) of the lateral compressions were followed by an aggressive response from the opponent.
