Chernobyl's birds are adapting to radiation

Birds in the exclusion zone around Chernobyl are adapting to - and may even be benefiting from - long-term exposure to radiation, ecologists have found. The study, published in the British Ecological Society's journal Functional Ecology, is the first evidence that wild animals adapt to ionising radiation. The Chernobyl disaster, which occurred on April 26 1986, had catastrophic environmental consequences. However, because it remains heavily contaminated by radiation, the region represents an accidental ecological experiment to study the effects of ionising radiation on wild animals.
Laboratory experiments have shown that humans and other animals can adapt to radiation, and that prolonged exposure to low doses of radiation increases organisms' resistance to larger, subsequent doses. This adaptation, however, has never been seen outside the laboratory in wild populations. The results revealed that with increasing background radiation, the birds' body condition and glutathione levels increased and oxidative stress and DNA damage decreased. "The findings are important because they tell us more about the different species' ability to adapt to environmental challenges such as Chernobyl and Fukushima."

i think it was pbs that did a documentary on wolves in chernobyl..
basically the ecosystem and wildlife in it were functioning normally despite high radiation. _________________ "i don't have pet peeves, i have major psychotic fucking hatreds"

The viral marketing for the new S.T.A.L.K.E.R. game is getting weird. _________________

I just watched that documentary, it was very interesting. Not only is the wildlife surviving, it's thriving.

what I did hear is that the trees that died since the incident aren't decaying, or decomposing (a dead tree in a normal environment would decompose, at maximum, in a 10year span but usually takes less)
thats because the fungi, microbes and bugs in charge of the decomposing process are scarse in that radiated soil
and it represents a problem... there's no room for more growth, with all the leaves and tree corpses lying around.

so i wouldnt rate wildlife being functionining normally in chernobyl. with almost 100% of the trees being zombie trees...

The reason for this lack of decay around Chernobyl is that microbes, bacteria, fungi, worms, insects, and other living organisms known as decomposers (because they feed on dead organisms) are just not there and not doing their jobs. Mousseau and his team discovered this after leaving 600 bags of leaves around Chernobyl in 2007. When they collected the bags in 2008, they found that the bags filled with leaves placed in areas with no radiation had decomposed by 70 to 90 percent, but the leaves in areas with radiation? They only decomposed about 40 percent. “There is growing concern that there could be a catastrophic fire in the coming years,” Mousseau told Smithsonian.
Besides getting rid of what is basically tinder for wildfires, decomposers are essential when it comes to plant growth because they put nutrients back into the soil, and back into the environment generally. The lack of decomposers could also explain why the trees that are alive around Chernobyl are growing very slowly. These Chernobyl trees cover about 660 square miles of the Zone of Alienation and have been absorbing radionuclides like strontium 90 (causes bone cancer) and cesium 137 (effects range from nausea to death) for almost three decades. If these trees are burned, these radionuclides would be released into the atmosphere as “as inhalable aerosols” reported Scientific American last year, citing a 2011 study. Besides inhaling cancer-causing particles in the air traveling hundreds of miles away, the biggest threat would be to food like milk and meat “produced as far as 90 miles from the fire.”
In fact, the threat of a Zone of Alienation wildfire spewing radioactive particles has been a concern among environmental scientists since 1992. The threat has only gotten worse due to the longer, drier summers attributed to climate change.
There are firefighters stationed around the Zone of Alienation specifically for preventing a forest fire inside, but they’re “obviously not prepared for a major wildfire situation” says SA, with hardly any “professional training, protective suits or breathing apparatuses.” Firefighters currently scout for fires by climbing six watch towers a day, along with the help of one helicopter that is “occasionally available.” They do have a Soviet tank that has been retrofitted with a 20-foot-blade though, to chop down and crush the dead trees that refuse to decay currently littering the roadways.
