Research Interest

Recent changes in the use of artificial light (intensity, light spectrum) might have an increasingly negative influence on mammals concerning their behavior, condition and fitness. During my PhD I want to examine the effects of artificial light at night on small mammals under semi-natural conditions. I will focus especially on the effects of different light intensities and spectra and on the prolonged effects that might exist after a phase of artificial illumination.
