Effects of short-term multi-pollutant exposure on the oxidative stress status of captive songbirds

The human influence on Earth's ecosystems is omnipresent. Artificial light at night (ALAN), anthropogenic noise and air pollution, are inherent features of human activities and infrastructure and pose novel environmental challenges to urban-dwelling wildlife. So far, most of the studies investigating the impacts of exposure to urban pollutants on animals have either investigated the effects of urban environments per se, or of single pollutants. However, urban pollutants co-occur, and interactive effects may arise when acting in combination, but we lack a deeper understanding of the effects of combined exposures. Here, we experimentally exposed captive zebra finches Taeniopygia guttata in a full-factorial design to increased levels of ALAN, anthropogenic noise and/or soot and measured oxidative stress status in blood before and after a five-day exposure. We found that the combined exposure to ALAN and noise led to a positive synergistic effect (higher levels than the sum of individual ef..., , , # Data from: Effects of short-term multi-pollutant exposure on the oxidative stress status of captive songbirds
