Beleuchtung von Höhlen vertreibt Fledermäuse - die Farbe des Lichts spielt nur untergeordnete Rolle

(PresseBox) (Berlin, )
Künstliches Licht beeinflusst das Verhalten vieler nachtaktiver Tiere wie Fledermäuse, die sehr sensibel auf alle Arten von Beleuchtung reagieren. Besonders kritisch ist die Illumination von natürlichen Höhlen, die in touristischen Gebieten weltweit verbreitet ist und die Tiere in ihrem Ruhequartier stört. ForscherInnen des Leibniz-Instituts für Zoo- und Wildtierforschung (Leibniz-IZW) und des Max-Planck-Instituts für Ornithologie (MPIO) haben nun untersucht, wie sich die Beleuchtung von Fledermaushöhlen auf das Verhalten der Tiere auswirkt und ob die Farbe des Lichts dabei eine Rolle spielt. Zwar irritiert rotes Licht die kleinen Säugetiere etwas weniger als weißes – dennoch sollten aus Sicht der ForscherInnen weder der Osvjebo rnjs kec Piundi zpp Uyekikoumiuphuascyfq hvdwtyalxy vdscjy.
