Low impact of two LED colors on nocturnal insect abundance and bat activity in a peri-urban environment
Abstract Artificial light at night (ALAN) is an important driver of change in ecological environments of the 21th century. We investigated the impact on nocturnal insect abundance and bat activity of two LED light colors (warm-white 2700 K, cold-white 6500 K) in a peri-urban environment. Bat activit...
