Abstract |
Ecotoxicological studies for pesticide risk assessments strive to develop cause-and-effect relationships between pesticide application and adverse effects on birds (both as individuals and as populations) and to determine the mechanisms by which the observed effects occur. In order to accomplish this, data are collected to determine if the location of the birds put them into potential contact with the pesticide, how the pesticide changes behaviors and the physiology of the animals, and how these changes result in increased mortality and reduced reproduction. Radiotelemetry and other remote sensing technologies can be powerful tools to aid in gathering the data. |
