Effect plot of the variables having a significant influence on the occurrence of socio-sexual contacts in GLMM2 and GLMM3 (a,b; Table 2). (a) The probability of the MSP onset following another female’s MPS onset within three days (Y axis) was highest between females with low affiliation levels (X axis); (b) the occurrence of socio-sexual contacts between females (Y axis) increased when females were synchronized on MSP (Y axis).
