Stronger negative relationship of wild bird abundance and radiation level seen in Fukushima than Chernobyl

On 8/14/2014, Oxford Journals published the report about the negative relationship of wile bird abundance and radiation level commonly seen in Fukushima and Chernobyl on “Journal of Heredity”.

The report was written by Timothy A. Mousseau from University of South Carolina et al.


In this report, it is stated that the abundances of Fukushima birds, butterflies and cicadas were negatively affected by radiation exposure like Chernobyl.

Especially the abundance and diversity of forest and grassland birds were dramatically lower in contaminated areas of Chernobyl, and the situation was very similar for birds in Fukushima at the moment of July of 2011.

However comparing the common types of birds to both of the regions, the negative relationship between abundance and radiation level was significantly stronger in Fukushima.

The report assumes that the difference might be due to the fact that it has been over 20 years since Chernobyl accident took place, which may affect the ecological selection for resistance, and also nuclides of relatively short half-life such as I-131 and Cs-134 have mostly decayed in Chernobyl.

La relation entre l’abondance des oiseaux et la radioactivité est plus fortement négative à Fukushima qu’à Tchernobyl


Le 14 août 2014, le Oxford Journals a publié dans son “Journal of Heredity” un article montrant la relation négative qui existe entre l’abondance des oiseaux sauvages et la radioactivité couramment observée à Fukushima et à Tchernobyl .
L’article est signé de Timothy A. Mousseau de l’université de Caroline du Sud, et d’autres.

Dans cet article, il est affirmé que l’abondance des oiseaux de Fukushima, ainsi que des papillons et des cigales est négativement impactée par la radioactivité comme à Tchernobyl.
En particulier, l’abondance et la diversité des oiseaux des milieux ouverts et forestiers se sont gravement effondrées dans les zones contaminées de Tchernobyl et la situation était très similaire pour les oiseaux de Fukushima en juillet 2011.
Cependant, la comparaison des espèces courantes d’oiseaux des deux régions montre que la relation négative entre abondance et radioactivité est significativement plus forte à Fukushima.
L’article suppose que la différence est sans doute due au fait que l’accident de Tchernobyl a plus de 20 ans, ce qui a pu induire une sélection écologique des plus résistants et aussi que les nucléides à période relativement courte, comme l’iode 131 et le césium 134 ont pratiquement disparu à Tchernobyl.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
