Abstract

Artificial light at night is an environmental disturbance that can alter natural conditions and influence the behavior of nocturnal wildlife, including fruit bats. This study aimed to examine the relationship between light intensity, nocturnal activity patterns, and hunting or foraging performance of fruit bats (Pteropus spp.) in an agroforestry environment. A quantitative correlational approach was applied by measuring nighttime light intensity using a digital lux meter at several observation points representing different illumination conditions. Nocturnal activity and hunting or foraging behavior were systematically observed during nighttime periods, and the relationships among the observed variables were evaluated using correlation analysis. The results showed that increasing light intensity was associated with decreasing nocturnal activity and hunting or foraging frequency. Fruit bats were more active in darker areas, while locations with greater illumination showed lower levels of movement and food-searching activity. These findings indicate that nighttime illumination is an important environmental factor associated with the behavioral patterns of fruit bats in agroforestry landscapes. Maintaining dark habitat patches, vegetation cover, and appropriate nighttime lighting management may therefore contribute to the conservation of fruit bats and support their ecological functions within managed tropical landscapes.
