Résumé :	Species differ in their susceptibility to radiation because of differences in their ability to sustain toxic and genetic effects caused by radiation. We censused breeding birds in Fukushima Prefecture, Japan, during 2011-2014 to test whether the abundance and diversity of birds became increasingly negatively affected by radiation over time. The abundance of birds decreased with increasing levels of background radiation, with significant interspecific variation. Even though levels of background radiation decreased over time, the relationship between abundance and radiation became more negative over time. The relationship between abundance and radiation became less negative with increasing trophic levels. These findings are consistent with the hypothesis that the negative effects of radiation on abundance and species richness accumulate over time.
