TOKYO -- Researchers in Japan have found signs of mutation in butterflies, signaling one of the first indications of change to the local ecosystem as a result of last year's nuclear accident in Fukushima, according to one of the first studies on the genetic effects of the incident.

Joji Otaki from the University of the Ryukyus in Okinawa, who led the research, collected 144 commonly-found pale grass blue butterflies two months after the March 2011 accident at the Fukushima Dai-ichi nuclear plant.


Initial results indicated that roughly 12 percent of the butterflies showed signs of abnormalities, such as disfigurement in their antennas, smaller-sized wings, change in color patterns and indented eyes, Otaki said.

Even more alarming, when he collected another 238 samples six months later he found that those abnormalities had increased to 28 percent and the mutations had doubled to 52 percent in their offspring.

To see the effects of internal exposure to radiation, unaffected clean butterflies were also fed cesium-coated leaves collected from Fukushima. The result was a reduction in the size of those butterflies, as well as a lower survival rate.

In Japan, a nuclear ghost town stirs to life

The Fukushima disaster occurred after a 9.0-magnitude earthquake knocked out a power line at the plant and generated a tsunami that flooded the facility's emergency generators, destroying the plant's cooling system. Catastrophic meltdowns occurred in three reactors, releasing radiation that has tainted the surrounding environment.

Five nuclear plants in total suffered some level of damage from the earthquake and tsunami; all but Fukushima Dai-ichi were shut down safely.

'Something has gone wrong'
Otaki, who has been studying these butterflies for 10 years to analyze the effects of global warming, said that butterflies are the best environmental indicators because they are widely found in almost any environment.

"But since we've seen these effects on butterflies, it’s easy to imagine that it would also have affected other species as well. It’s pretty clear that something has gone wrong with the ecosystem,” he said.

However, at the same time, he also warns that because each species’ sensitivity to radiation varies, it was too early to immediately apply these finding to humans.

But what is clear, said Otaki, is that the genetic changes found in these butterflies indicate a disruption in Fukushima's ecosystem and that more study is needed to learn the full scope of the effects of the radiation released into the environment.

"Effects of low level radiation is genetically transferred through generation, which suggests genetic damage. I think it’s clear that we see the effects passed on through generations," Otaki added.

And of course the radiation levels are just 'low-level' because the samplers followed orders and covered their geiger counters with lead.

Worry much. Don't eat tuna.

Half-lifes are determined in labratory conditions, NOT in an ecosystem. Nature dilutes the harmfull effects as the isotopes disperse upward in the food chain.

Radioactive elements (by theire very nature) are extremely heavy and do not disperse far from their source.

Except when accompanied by an explosion such as what happened at Chernobyl.

      I was going to China last month and to get a super low fare I had a 2 day layover in Japan not far from Fukushima. It was quite beautiful there but I saw a 'public health announcement' that told everyone to keep small pets inside and not to let children under 2 years old outside.

      It seems there is now a mutant buterfly that is 1.5 feet long and eats meat. IT does not discriminate. It will eat birds, rats, puppies or children. It is capable of lifting approximately 30 lbs to fly away with it's prey and much like normal butterfly's that suck from flowers, they inject a tube into their prey and suck out the liquids.

      That's the good news. They recently found a mutant butterfly that actually has fangs and a mouth that enable them to literally eat what they capture. there is a huge danger to America because these insects like many before them, may end up on cargo ships that load cars in Japan to bring to the USA where the cars and bugs end up here.

      We have Tiger muscles in the Great Lakes, Killer bees & Killer Ants in southern USA, Med flys (we supposedly wiped them out several years ago) and othjer dangerous animals and bugs that already immigrated here. We can not afford this new dangerous creature.

      Write to your congressman and Governor and Presidet Obama and tell them to end all imports from Japan until after these creatures are eliminated !

        One of the big problems with Evolution, indirectly mentioned in the story-- mutations are almost always harmful and Evolution needs like a million beneficial ones in a row to go from one-celled organism to human.

        Of course, this is from a "nuclar" accident, but the mutated moths are all screwed up

        "The result was a reduction in the size of those butterflies, as well as a lower survival rate."

        Non-"nuclar" mutations are the same, nearly always negative and not beneficial, and when any are beneficial, there's bad side effects. Completely impossible for mutations to advance a species from one functioning one to another, more advanced fully functioning one.

        Evil-lution (that's not too anti-science to spell it that way, right?) requires a lot of faith that things we've never observed (millions of back to back positive mutations) happened in the distant past.

          Every living thing on Earth is a mutation. We get radiation from the Sun, from the Cosmos, from rocks, etc. Everyone with a granite counter top has a source of radiation in their kitchen.

          Life is thriving in Chernobyl.

            Yes we get radiation from multiple sources but it is cumulative. Since there are so many natural sources, why add a man made one?

            Life is not "thriving" in Cheernobyl, the animals there are surviving but are highly radioactive. One can expect shorter lifespans and more sickly animals than usual. From the second source that you sighted:

            "Moller and Mousseau have shown that certain species in the area have a higher rate of genetic abnormalities than normal.

            "We find an elevated frequency of partial albinism in barn swallows, meaning they have tufts of white feathers," Mousseau said.

            Late last year Moller and Mousseau published a paper in the Journal of Animal Ecology showing that reproductive rates and annual survival rates are much lower in the Chernobyl birds than in control populations."

            Animals are flocking there because it is abandoned. That does not mean they will remain healthy.

            All the people saying how bad the toxicity is of the radiation leaks from one location and nuke plant...I'm betting most of you threw out enough Cadmium in your dry cell battery trash over the years to do many times more damage to the planet globally. Did you recycle all those batteries you used? Did the re-cyclers do their job properly? Did you know that Cadmium is the most toxic heavy metal that has a half life of 30 years? Europe banned its use in industry, but oh no, not the USA, couldn't possibly allow a few jobs to be lost as we shifted our technologies.

                "Researchers in Japan have found signs of mutation in butterflies, signaling one of the first indications of change to the local ecosystem as a result of last year's nuclear accident in Fukushima..."................How can this be possible?

                The Jap government told us that there was no cause for concern, that the amount of radiation released was minuscule at best.

                Tokyo Electric Power Company told us that the amount of radioactivity posed no health threat beyond the evacuation area and would dissipate.

                The US government reassured us that the release was minimal and would have no long term effects.

                Our own NRC told us that there was no imminent threat to public health or safety outside of the evacuation area.

                That is it, I have had enough - I am calling out those Researchers in Japan of this butterfly research as big, fat liars.

                Lies, Lies, Bold face Lies!!!!

                Liar, Liar Pants on Fire!!!!

                There is no way you can ever convince me that the Jap, US, TEPCO and the NRC among others would collaborate to lie to us.

                Governments and government entities lying to us, why that would be unheard of in this day and age!

                I think, ergo................

                John Doe; you seem to be moderately informed and knowledgeable, however you come across as a shill for the nuclear industry.

                BTW, should you or anyone wonder how safe nuclear waste is in oceanic waters, do a little research on the nuclear waste that the US has been dumping near the Faralon Islands just off the coast of California near San Francisco. Very enlightening and lots of interesting mutations in the sea life in that region.

                Also, there was a nuclear incident years and years ago near Walla Walla, Washington. We don't hear too much about that one. Good reading for those interested.

                Then there's the infamous Bikini Atoll testing out in the Pacific ocean. My, oh my, we did wreak a bit of havoc there and the natives had to evacuate their homes and the island for a loooong time.

                So, no, nuclear power is not safe and the problems it introduces into the ecosystem may not be fully appreciated or understood for millennia because, quite often, the drastic immediate results, like a badly mutated butterfly or deformed fetuses, while sensationalistic, may not be the most serious or the most significant. It is the long term, subtle changes which our society is too ADD to pay much attention to that will be the determining factors in the path of our evolutionary journey.

                Peace. :)

                Imagine the mutations happening as we speak in the ocean. Already they have found bright colored Lobsters in the oceans miles off Japans shore since the incident. I find it amusing that the media shrugs this phenomena off, but then says a month later,

                "A mutated butterfly from Japan!? What could happen next!?"

                Pfffft...I've got a picture I took right on my front porch of a mutilated butterfly...wings all deformed, body all weird but still clinging to life. My yard is chemical free on purpose. Now, just what happened to this butterfly? Right here in America. This thing should have been very big and beautiful but instead was quite scary to look at. Me thinks we need to keep a check on our own as well.

                          (39 References to Mothra?) Ah but Desghidorah looks much like the top ticket conservatives for the election.

                          Unlike the previous generation Ghidorah, Desghidorah has four legs, like the two candidates combined, and aside from their friendly appearance, although be it other worldly, is has three heads allocated as follows: One pair middle and left for Romney facile tactics, here, then there, then over there. The remaining head is steadfastly on the far right and spews a cutting flame. Desghidorah (script below) may seem recent it follows the current campaign, but it does end very democratically, even if the sweet singing pair are your choice.

Leo differs from Mothra as he is commonly labelled as a male. Plus, unlike Mothra who is usually portrayed as being concerned more for the plights of her homeland and people, Leo takes on a more active role as a protector of the Earth, as well as taking on a Gamera-like affection for children.

                          http://godzilla.wikia.com/wiki/Desghidorah

                          Desghidorah, ('DesuGidora') is the first antagonist monster of the Rebirth of Mothra series.

                          This Ghidorah was a return to its roots as a malevolent world destroying demon, and wasn't controlled by anything. It attacked out on its own free, evil, will. Also, it has four legs instead of just the usual two.

                          Sixty-seven million years ago, an unspeakable horror arrived in the galaxy. A relative of the King of Terror himself, Desghidorah attacked Mars and turned it into a barren wasteland, literally sucking the life out of the planet. This creature, not content to allow just one planet in this solar system to suffer its wrath, advanced to the nearby planet of Earth. Desghidorah began its assault on the planet, but one thing it didn't expect was retaliation! A race of intelligent beings called the Elias populated the planet, and they fought against the three-headed demon. The guardians of the Elias, a race of giant moths named Mothra, engaged Desghidorah. The war between the giant insects and the space monster was long and brutal. Finally, the despised dragon was defeated, buried, and sealed in a secret location. Earth, however, was nearly ruined by the Great War. The dinosaurs and many other species of animals went extinct, and the civilization of the Elias was almost obliterated. In the end, only three beings of this ancient species survived; their names were Moll, Lora, and Belvera. Moll and Lora became the avatars of Mothra, but Belvera, corrupted by the loss of her species, became evil. She sought to one day release Desghidorah upon this world once more...
                          By the year 1997, deforestation and pollution were at a fever pitch. A logging company was clearing out the lush and beautiful Hokkaido forests, when the workers stumbled upon a strange buried structure with ancient writing. One of the workers discovered a small pendant at the center of the object and removed it, which caused the earth to suddenly quake. He gave the pendant to his daughter as a present, but Belvera quickly located the little girl and stole the pendant, the "Seal of Elias," from her. Seeking out their sinister sister, Moll and Lora arrived to recover the seal. Belvera fought against her siblings for control of the seal, but Belvera and her reptilian steed, Garu-Garu, prevailed and escaped. Moll and Lora's transport, Fairy, was unable to fly, and the twin fairies were grounded. They explained to the humans that the seal had been holding Desghidorah captive for many years, and with it, Belvera would attempt to control the terrible monster.

                          At the site where the ancient artifact was uncovered, the ground shook violently, and Desghidorah's tomb began to rise into the sky. The man who discovered the seal was placed under the control of Belvera, who used him to demolish the tomb by driving a bulldozer carrying a load of dynamite directly into the jagged structure. Her plan was a success, and after it absorbed a massive amount of energy from the surrounding forests, Desghidorah announced its triumphant return to a terrified world. The violent beast continued to draw the life out of the forest, for it was planning to soon gain enough energy to take to the skies on crimson wings.

                          The Elias watched in horror; they knew what they must do! Mothra was the only being that could stand a chance against this soaring savage, so they called upon their guardian to come forth and do battle with the wicked creature once more. Mothra was protecting her newly laid egg, but when she was summoned, she flew to Japan to fight the three-headed demon. Mothra attacked Desghidorah, and the two engaged in mortal combat! Mothra, however, was old and weak after giving birth, and Desghidorah was far too vicious for her to handle. Desghidorah relentlessly attacked Mothra, causing great harm to the benign protector. Sensing his mother's dismay, the egg that Mothra left behind began to hatch, even though it hadn't grown thoroughly enough. The baby began his journey to assist his mother, and when the larva arrived on the scene of the battle, it attacked Desghidorah using its energized silk. This new rival momentarily confused the grotesque gargantuan, but it swiftly located the young creature and bit into his soft flesh. It sadistically lifted the now defenseless young creature in its horrible mouths, and beat the tiny monster against the ground as blood spewed from its wounds. The infant was thrown aside as his mother came to his defense. Desghidorah and Mothra battled fiercely, but she was again repelled. The larval Mothra camouflaged himself and continued his attack. When Desghidorah discovered his location, Mothra entered the fray once again. She lured Desghidorah into a waterway, and caused him to destroy a dam. Mothra grabbed her infant and fled the scene as Desghidorah was washed away by the fury of the surging water.

                          Mothra flew out to the sea to safety, but she was far too weak to go any further. She dropped her child into the water and crashed into the surf, not far ahead of him. The baby attempted with futility to keep her afloat, but she sank below the surface to a watery grave. Her Elias companions wept for her, but her infant was ready to incite swift and brutal revenge on his mother's murderer. He swam away and formed a chrysalis and began to metamorphosize.

                          Desghidorah, now unopposed, continued to absorb the life out of Hokkaido, creating a massive cloud that covered the island. Eventually, it gained enough energy, and, from its stone-like back, it sprouted two mighty wings. Desghidorah was finally ready to take on the world in full force.

                          The Mothra larva sought out an ancient, powerful tree and by using its energy, transformed into an even more powerful adult Mothra. The new Mothra once again engaged Desghidorah in battle, this time defeating him and once again imprisoning him within his ancient mountain prison, never to be seen again.
