Results of the Generalized Linear Mixed Model of the biological and environmental factors influencing the frequency of play of Javan slow loris (Nycticebus javanicus). ΔAIC = 42.11, i.e., the difference between the AIC of the first ranked model and the AIC of the null model. Data are based on 1137 days of data collection (considering also days when the individuals did not play) between April 2012 and December 2020.
