Abstract This study demonstrates that the reproductive seasonality ofMacaca fuscata seems to be more affected by environmental temperature than by photoperiod. Mean conception dates for 25 groups of Japanese macaques species did not correlate with latitude. Instead, they were positively related to mean fall and winter temperatures and negatively related to the magnitude of the decrease in the mean temperature from summer to fall. Evidence from transplanted groups supports the hypothesis that environmental temperature is a decisive factor in determining the timing of mating activities of Japanese macaques. These results are also consistent with the concept that, in temperate zones, environmental temperature is probably the best indicator of local climatic characteristics.
