Low impact of two LED colors on nocturnal insect abundance and bat activity in a peri-urban environment

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 activity (predominantly Pipistrellus pipistrellus ) was largely driven by prey availability (insects), while insect abundance was responsive to nightly weather...
