“…Moonlight intensity affects communication [13], orientation [17] and risk-reward trade-offs [18,19]. Recent research suggests that ALAN interferes with lunar guided migration [20], orientation [21], sleep time [22] and reproduction [23] at intensities similar to natural moonlight.…”

Artificial light at night reverses monthly foraging pattern under simulated moonlight

Mounting evidence shows that artificial light at night (ALAN) alters biological processes across levels of organization, from cells to communities. Yet, the combined impacts of ALAN and natural sources of night-time illumination remain little explored. This is in part due the lack of accurate simulations of the complex changes moonlight intensity, timing and spectra throughout a single night and lunar cycles in laboratory experiments. We custom-built a novel system to simulate natural patterns of moonlight to test how different ALAN intensities affect predator–prey relationships over the full lunar cycle. Exposure to high intensity ALAN (10 and 50 lx) reversed the natural lunar-guided foraging pattern by the gastropod mesopredator Nucella lapillus on its prey Semibalanus balanoides . Foraging decreased during brighter moonlight in naturally lit conditions. When exposed to high intensity ALAN, foraging increased with brighter moonlight. Low intensity ALAN (0.1 and 0.5 lx) had no impact on foraging. Our results show that ALAN alters the foraging pattern guided by changes in moonlight brightness. ALAN impacts on ecosystems can depend on lunar light cycles. Accurate simulations of night-time light cycle will warrant more realistic insights into ALAN impacts and also facilitate advances in fundamental night-time ecology and chronobiology.

“…Smolka et al (2016) evidenciaron que la tortuosidad de la misma especie aumenta a menor luminancia, al igual que en Scarabaeus satyrus (Boheman, 1860) (Coleoptera: Scarabeidae). S. satyrus se desorienta con iluminación indirecta, debido al uso de señales terrestres para orientarse en sitios iluminados (Foster et al, 2021).…”

“…La luz como factor ambiental es fundamental para el ritmo biológico de los animales, y es notable en la bioluminiscencia o la orientación por cuerpos celestes (Teikari, 2007;Elgert et al, 2020;Foster et al, 2021). Los patrones de luz natural están regidos principalmente por el Sol y la Luna, y varían según el tiempo y la ubicación geográfica (Longcore y Rich, 2016).…”

Actualmente, el uso masificado de fuentes de luz artificial permite el desarrollo de varias actividades. Sin embargo, pueden causar perturbaciones en los insectos adaptados a los cambios de luz natural. El objetivo fue recopilar evidencia de los efectos de la luz artificial en los insectos del orden Coleoptera. Los resultados evidencian sensibilidad hacia la luz, debido a los fotorreceptores de los coleópteros. Identificamos repercusiones a nivel individual, poblacional y comunitario. Estos efectos tienen aplicación para la gestión de la iluminación en la conservación ecológica, manejo de plagas e investigaciones médicas. Concluimos que los efectos son potenciales para la pérdida de biodiversidad si la gestión de la iluminación no es la adecuada.

The global increase in light pollution is being viewed with growing concern, as it has been reported to have negative effects ranging from the individual to the ecosystem level. Unlike movement on the ground, flying and swimming allows vertical motion. Here, we demonstrate that flight altitude change is crucial to the perception and susceptibility of artificial light at night of air‐borne organisms. Because air‐borne species can propagate through the airspace and easily across ecotones, effects might not be small‐scale. Therefore, we propose including airspace as a vital habitat in the concept of ecological light pollution. The interplay between flight altitude and the effects of light pollution may not only be crucial for understanding flying species but may also provide valuable insights into the mechanisms of responses to artificial light at night in general.
