TAILIEUCHUNG - Air pollution impacts on birds and insects

The African American community, including environmental justice advocates, is perceived as less influential when it comes to environmental issues. Mainstream organizations are often reluctant to collaborate, share, acknowledge and integrate the perspectives of People of Color. That all parties would benefit from such collaboration is clear. The current collaboration is unique and timely because it seeks to leverage the collective strength of three influential networks to build an equilateral triangle that includes traditional civil rights, environmental justice and mainstream environmental perspectives | Air pollution impacts on birds and insects Project leader Tapio Eeva docent . students Jouni Sorvari Saila Sillanpaa . student Ville Vaha-Iitu Collaborators Mikko Nikinmaa Univ.

Sci Background The main results Future work The latest results Media Publications Background Effects of air pollution on the Pied Flycatcher Ficedula hypoleuca and the Great Tit Parus major has been studied in the surroundings of a copper smelter of Harjavalta SW Finland since 1991. Our aim has been to find out how atmospheric emissions of heavy metals especially copper nickel and lead and acidic substances affect the breeding success and survival of birds. The main results One of the main interests in our project has been whether the detrimental effects are direct toxic effects or indirect effects . due to decreased amount of food . We have found both. The two bird species respond differently to pollution. The pied flycatcher suffers from poor quality egg shells and growth abnormalities of nestlings but these effects are restricted only to relatively small area 1 - 2 km around the factory complex. The great tit suffers most in late nestling stage when the growth of nestling is retarded and mortality increased. In summary the pied flycatcher seems to suffer more from the direct toxic effects whereas the great tit suffers more from the reduced amount of suitable food for nestlings. Great tits in the polluted area are fading We have found that the air pollution can cause changes in the plumage colour of great tits. The breast feathers of the great tit are normally yellow but the yellow plumage of young great tits is significantly paler the closer to the pollution source they live Functional Ecology 12 607-612 .
