Effects of anthropogenic light on anuran calling site

Human activities, including artificial nighttime lighting, can harm the natural environment. Although recent research indicates that artificial light pollution affects animal behavior, its impact on nocturnal anurans (frogs and toads) hasn't been extensively studied. This research examined how artificial light affects where male anurans in east Texas choose to call. Light levels were measured at various urbanized sites, and the light intensity where the anurans were found calling was compared to the overall light environment. The study found that in brightly lit areas, male anurans often chose darker spots for calling compared to the surrounding environment. Yet, the chosen spots in these areas were still brighter than the preferred spots in less lit areas. This suggests that while anurans prefer darker places for calling, those in urbanized regions might not have that choice. Therefore, increased light pollution could lead to a loss of preferred habitats for male anurans.
