Research overview: wildfire smoke and sublethal effects on wildlife

Beyond burning habitat, wildfire produces smoke whose sublethal effects on wildlife, including mammals, are an emerging research area. This overview surveys what is known and hypothesized about smoke exposure affecting respiratory health, behavior, and physiology in animals, the challenges of studying such diffuse effects, and why extreme smoke events accompanying megafires have raised the question. It reviews the largely indirect evidence and the methodological difficulty of isolating smoke impacts. The synthesis frames smoke as an under-studied dimension of fire's effect on wildlife, explaining why, as climate-driven fires grow larger and smokier, researchers are beginning to ask whether the air quality consequences for cats and other animals extend beyond the burned area itself.
