Differences in irradiance spectra of the lights used.

<p>To test the impact of urban light pollution on <i>Microcebus murinus</i>, we exposed animals to (A) moonlight treatment (light intensity: 3.9±0.1 nmol photons.s⁻¹.m⁻²); then to (B) light pollution treatment (light intensity: 24.2±0.9 nmol photons.s⁻¹.m⁻²; light of a high pressure sodium streetlight located 50 m in front of the experimental room; peak at 592 nm).
