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.
