The dark side of light: Consequences of disrupting natural light for the behavioral ecology of arthropods.

Light cycles are integral to biology as changes in both light intensity and color have drastic effects on organismal behavior such as circadian rhythms, migration, reproduction, foraging and predation. Furthermore, humans are erasing natural light cycles due to artificial light night, which is becoming pervasive globally. In this talk, I introduce the importance of light cycles for organisms and how artificial light affects myriad organisms. Then I will dive into how artificial light at night is concerning relative to arthropod declines. I highlight a few studies: tropical nocturnal bees and visual physiology, moths of the Rocky Mountains and predation under street lights, and then an ongoing study investigating lighting effects of spider-fly interactions. This talk will emphasize the importance of understanding the implications of light for conserving habitats and what measures individuals can take to reduce their contribution to the pollution of light.
