An analysis of courtship behaviour in the four-eyed spotted turtle, Sacalia quadriocellata (Reptilia : Testudines: Geoemydidae)
chi-square test, cinematographic techniques, courtship behaviour, intraindividual dyadic transition matrix, kappa analysis
A total of 168 courtship sequences from 12 male and 18 female adult captive Sacalia quadriocellata were recorded on video. Thirty male and four female discrete motor patterns were defined and described. The behavioural sequences were summarized in an intra-individual dyadic transition matrix and analyzed using chi-square and kappa analyses. Courtship behaviour models and a flow diagram were constructed for this species. The male display patterns involved tactical and visual signals to induce female receptivity to mating. In response, females may emit olfactory signals for gender recognition. Female rejection of male suitors resulted in a male success rate of 4.17%. Only seven copulations were observed. Copulation only occurred when a female became quiescent and relaxed her tail for coition.
