Birds as Bioindicators of Pollution in Aquatic and Terrestrial Environments
Birds have been widely used as bioindicators. In this study we face the use of birds as bioindicators of metal pollution in two different scenarios of contamination: one that takes place in an aquatic environment, the Ebro river basin, and a second that occurs in a terrestrial environment, the Boliv...
