Abstract
Traffic and roads are inevitable consequences of urbanization and the cause of high particulate, noise and artificial night lighting pollution. These three anthropogenic factors, along with food quality are believed to have major impact on wildlife (e.g. reduced reproduction, survival and increased disease). However, causal relationship and synergistic effects have not been established. This project aims to fill this gap in 3 main goals using highly innovative multidisciplinary approaches. Firstly, by using a specially designed chamber we will determine single and synergistic effects of diesel generated pollutants, noise and night light for birds? oxidative stress and inflammatory responses ? two physiological markers of disease. This will be feasible through a unique collaboration using state-of-the-art methods in the fields of ecology, physiology and aerosol physics. Secondly, in the same chamber the negative and potentially additive effect of poor nutrition will be tested. Preliminary data suggests that birds feeding on anthropogenic food sources have reduced capacity to deal with oxidative stress and inflammatory agents. Lastly, the crucial but often disregarded challenge of linking controlled studies to actual ecological impact will be taken seriously, by monitoring and sampling of wild bird populations. The ultimate goal of the project is to maintain healthy bird populations in urban areas by providing guidelines for precautions associated with urban development.
