Artificial light at night altered caracal movement and foraging

What the study found

Artificial light at night influenced caracal movement, habitat selection, and foraging behavior. The study found that caracals avoided direct artificial light, while also selecting areas closer to urbanization.

Why the authors say this matters

The authors conclude that artificial light sources influence distinct yet interconnected behaviors, and that understanding where and how artificial light at night affects species can inform mitigation and conservation strategies. They also note that artificial light at night is a pollutant that will continue to affect wildlife.

What the researchers tested

The researchers studied adult and subadult caracals of both sexes using GPS collars and nighttime behavioral data. They used integrated step selection functions to evaluate movement and habitat selection, and resource selection functions to examine habitat selection while foraging at kill sites. They assessed direct and indirect artificial light at night, including total upward radiance, public streetlights, and urban skyglow.

What worked and what didn't

Upward radiance strongly drove movement patterns, and caracals avoided direct artificial light. Caracals also selected areas closer to urbanization, and subadults appeared more tolerant of artificial light than adults. Foraging was primarily influenced by direct artificial light through public street lighting, with avoidance of highly illuminated areas.

What to keep in mind

The abstract does not describe specific limitations beyond the focus on adult and subadult caracals in the study area. The summary available here is limited to the information reported in the abstract.

Key points

  • Caracals avoided direct artificial light at night.
  • Upward radiance strongly affected caracal movement patterns.
  • Caracals selected areas closer to urbanization.
  • Subadults showed greater tolerance to artificial light than adults.
  • Foraging behavior was influenced mainly by public street lighting, with avoidance of highly illuminated areas.
