| Research Abstract |
I monitored the population changes of large terrestrial mammals using camera traps in three study sites in Sabah, Borneo (Danum Valley, Kinabatangan and Tabin). In all the study sites, large-scale mast fruiting was observed at the beginning of our research. In all the study sites, the proportion of photos including infants or multiple individuals of bearded pigs increased at the time of mast fruiting but such tendency was observed for other species. Among primates, only orangutans increased their number in response to increased fruiting intensity. These facts suggests that only minority of the large mammal species show numerical response to mast fruiting, such as increased reproduction in bearded pigs and migration in orangutans.
