Article Synopsis
- The study investigates how artificial light at night (ALAN) influences the behavior of Chaoborus flavicans insect larvae in open water habitats, particularly their distribution relative to predation risk and oxygen levels.
- During the day, these larvae hide in deep, dark waters to avoid fish, but at night, they are drawn to richer surface waters despite potential dangers.
- Experiments show that ALAN from street lights attracts fish and pushes Chaoborus to occupy mid-depth zones with limited oxygen instead of moving to safer anoxic depths, likely due to a balancing act between avoiding predators and meeting their oxygen needs.
Numerous studies have revealed that artificial light at night alters the natural patterns of light in space and time and may have various ecological impacts at different ecological levels. However, only a few studies have assessed its effect on interactions between organisms in aquatic environments, including predator-prey interactions in lakes. To fill this gap, we performed a preliminary enclosure experiment in which we compared the foraging effect of juvenile perch () on a natural lake zooplankton community in the absence and presence of light of high-pressure sodium (HPS) lamps mimicking artificial light emitted by a boat.
