灯光强度对东亚伏翼觅食行为的影响研究
A study on the effects of artificial light intensity on the foraging behavior in Japanese pipistrelle bats(Pipistrellus abramus)
摘要
Abstract
Artificial light has altered the nocturnal environments of most ecosystems,posing a threat to biodiversity and associated ecosystem services.Foraging behavior is essential for animals to obtain the nutrition and energy from the ex-ternal environment.To date,it remains uncertain whether the intensity of artificial light affects the foraging behavior in nocturnal animals.Here,we used Japanese pipistrelle bats(Pipistrellus abramus)as a model for insectivorous bats to in-vestigate the effects of artificial light intensity on their foraging behavior.We established three study sites situated 5 m below three different bridges.At each site,we monitored the intensity of artificial light and recorded the number of pass-es and feeding buzzes in P.abramus.The Kruskal-Wallis test showed no significant difference in the number of P.abra-mus passes between the relatively dark site and the site with low light intensity.However,a remarkable reduction in the number of P.abramus passes was observed at the site with high light intensity when compared to the relatively dark site.There was an increasing tendency in the number of feeding buzzes emitted by P.abramus at the site with low light intensity relative to the relatively dark site.The number of feeding buzzes in P.abramus was significantly diminished at the site with high light intensity relative to the site with low light intensity.Generalized linear mixed models indicated that the intensity of artificial light negatively influenced the number of passes and feeding buzzes in P.abramus.These results demonstrate that high levels of artificial illumination can disturb the foraging behavior of P.abramus.Our find-ings provide a scientific basis for the regulation of light pollution in habitats utilized by synanthropic bats.关键词
