by manipulating light intensities and providing a choice between dark and lighted environments. Crayfish were more active in the absence of artificial light and preferred dark environments even when light intensities were very low (~5 lx). Our results suggest that crayfish may increase sheltering behavior and seek out darkness in the presence of artificial light, potentially increasing shelter competition and reducing contributions of crayfish to ecosystem function.
