Glowing Green: A Quantitative Analysis of Photoluminescence in Six North American Bat Species
Ecology and Evolution, Volume 15, Issue 8, August 2025.We provide a quantitative analysis to confirm visual observations of UV‐induced photoluminescence in six North American bat species. We observed green photoluminescence on the wings, uropatagium, and hind limbs of all 60 museum specimens examined. Our results suggest the potential for photoluminescence to be homologous in origin among the species we ...
