Short Abstract

In nature, day-night cycles have gradual transitions at dawn and dusk, yet these transitions often are not reflected in laboratory studies of circadian behavior that utilize artificial light cycles. Most studies utilize instantaneous transitions from light to dark, including previous work on spider circadian behavior. To mimic natural conditions, two web-building species of spiders were entrained to light cycles with ramped, dusk transitions. The activity patterns of the spiders were compared to control light cycles and displayed mixed results.
