Wildlife Returning To Chernobyl 337

The wilderness is encroaching over abandoned towns in the Chernobyl exclusion zone. One of the elderly residents who refused to evacuate the contaminated area says packs of wolves have eaten two of her dogs, and wild boar trample through her cornfield. Scientist are divided as to whether or not the animals are flourishing in the highly radioactive environment: "Robert J. Baker of Texas Tech University says the mice and other rodents he has studied at Chernobyl since the early 1990s have shown remarkable tolerance for elevated radiation levels. But Timothy Mousseau of the University of South Carolina, a biologist who studies barn swallows at Chernobyl, says that while wild animals have settled in the area, they have struggled to build new populations."

      The article reports that one third of nestlings are malformed. What we have is a fairly natural cut: If the offspring is viable, it will end up being observed as behaving normally, it if is not then it won't be observed since it will be dead from, say, having the wrong shaped beak for its niche. It will be absent from counting surveys, making them biased. Most mutations are harmful so they do not survive. But, so long as less corrupted genetic material can migrate in, you'll get a superfical appearance of normalcy.

      The reason for preserving wilderness is to preserve biodiversity which is essential to maintaining a strong ecosystem. This accidental wilderness has many counts against it in that context.

          A higher mutation rate doesn't lead to an increased chance of a significant improvement in a species propagating. In sexual species in particular, a higher mutation rate will actually decrease the general evolution rates, either for a species to show a successful adaptation or for it to split off a new species. All the vast complexity of life we see around us results from the mechanisms of heredity developing newer and better ways of reducing copying errors. Even Nucleated cells themselves are an error reduction mechanism - put the genes in the middle behind extra barriers, so fewer chemicals can penetrate to affect the DNA. Sexual reproduction itself is another error reduction mechanism - combine copies from multiple sources and supress (many of) the defective ones. DNA itself won out over RNA as an encoding system because it had a much better copying error rate - and now only a few very primitive organisms remain that use RNA for encoding instead of just as a messenger molecule.
                  This is part of the standard theory as taught in real genetics courses to potential professional Biologists. Just about everyone else who thinks they support evolution has been miss-taught in high school biology or 'evolutionary biology for non scientists' type classes. Nothing personal, but it sounds like you got one of those sloppy pop courses.

        You know, if the animals live to leave offspring, it's not superficial appearance of normalcy, it's normalcy, never mind all the curruption going under.

        The purpose of an animal, is, after all, precisely this.

        As about 1/3 of offspring being malformed, this is far from bad for the wildlife. If 1/2 was, they'd do fine, hell, if 3/4 were, they'd do fine. Even if none of them had mutation, most of the animal offspring would die in infancy for plenty of other reasons (like natural predators).

          This is observed malformation; there's no mention of internal examinations or spontaneous abortions or eggs that don't hatch. I live on the edge of a forest and I see about 100 birds a day; none of these is visibly malformed.

          The article says radiation levels are 10 to 100 times normal background. This range is probably beneficial for humans and most other animals. Living there probably isn't bad from the standpoint of background radiation; but I wouldn't want to eat food grown there or live in a house without a dust filter.

          Things are getting better there faster than predicted, and if careful study is done we'll have more data for the theory of hormesis with respect to radiation.

              In a sense... yes.

              I bred at less than my replacement level. If everyone in the word were to follow that tendency, we would be able to half the population by roughly 2050 and half it again in the 20 years after that so by 2100 the population would be roughly 1.5 billion. The chinese made some of these extremely hard choices with regard to overbreeding and overpopulation and have benefited from doing so.

              The problem is that ignorant poor people and some religious people are going to breed us to the point where things are unpleasant all the time at the best or downright ugly and murderous at the worst.

              Overbreeding would be no problem if the overbreeders and their descendants were limited to a fixed plot of land. That way the descendants of people with sustainable breeding habits could live in a paradise while the overbreeders lived in hell on earth, died of starvation, and killed each other over precious water and living space.

              But no-- their descendants would feel they had a right to spread equally into everyone else's land. Thus spreading the consequences of their poor breeding choices.

              You can buy all the CFC's you want, conserve til you bleed, eat only grains (because meat is so inefficient) and eventually that will all be pointless unless a lot of humans die fast from something. Too many humans is the fundamental problem-- not global warming, not limited oil, not limited food, not limited water.

              If we do not address this fundamental problem- then everything else we do is similar to ignoring the huge hungry rampaging elephant in the room while we keep replacing the carpet and drapes.

                Except that the US isn't suffering from over population. That is what drives me nuts. There are places in Australia where rabbits are destroying the habitat because of massive over population. Killing off a few in Texas just isn't going to help. Killing hundreds or thousands in Texas isn't going to help. The Population of the US is pretty much flat and soon to be slightly declining once the Baby boomer's start to die off. In Europe and Japan you are seeing the same thing or a strong decline. That will do nothing to really help since the over population problem is other locations.

                But they won't, and so all you accomplished is selecting yourself out of the gene pool.

                We have a ton of resources on the planet. Supporting more humans with the resources that we have is a reasonably easy problem technologically. Yes, we have a high population compared to what a species without agriculture (and modern agriculture) could do, but we have those things. The earth could handle a bunch more population, but the trends indicate that human population growth is slowing quickly enough that it won't be a real issue.

                The appropriate tactic here isn't to have less kids, it's to have as many kids as you think you can reasonably educate. The only way we'll be able to keep quality of life up as a species is to have as high a percentage of well educated people as possible - that way there will be people around to suggest and implement rational solutions to problems.

                  The fascinating thing about technologically advanced regions is that the reproductive rates are much lower than low tech areas. This is because in technologically advanced cultures children have a higher cost/benefit ratio than in lower techs. Lower techs need the children to tend the field, watch the sheep, etc. etc. Where as higher techs need to spend money to educate and groom their children into productive roles.

                  I find this particularly neat in that the easiest deterent of overpopulation is perhaps technological proliferation.

    The article seems to posit a false dichotomy between increased rates of cancer and deformity and a flourishing animal population. The usual mutation rate for most animals is pretty damn small. You could probably increase it 100 fold if not more and still maintain a large population of healthy breeding animals. Since animals, like humans, are naturally programed to prefer to breed with healthy members of their species there is no reason to think that the harmful mutations would 'take over' and cause the local animals to die out. Also just because more animals die of cancer doesn't mean they don't live long enough to successfully breed.

    I mean it should be a lot like inbreeding. Sure inbreeding increases the number of seriously fucked up members of the population significantly so you wouldn't want to do it with humans but it can also be used to help establish certain useful traits fairly quickly. The animals living in the Chernobyl area might have more deformed babies, and no doubt if they had to fairly compete with non-irradiated members of their kind they would be at a disadvantage, but the long term effect might just be to increase the rate at which they evolve.

    Of course you can't really decide this with a thought experiment but it is annoying that the article suggests increased deformity and cancer rates in individual animals is incompatible with overall health of the species/group.

      The scientists involved failed to note that the predator and prey populations are under equal hardship within this ecosystem.

    There's this website [kiddofspeed.com] where this woman chronicles her motorcycle rides through the area around Chernobyl. The last time I visited the site was several years ago; it appears she's returned since then. It's very fascinating, and without a doubt, eerie. If I remember correctly she mentions having spotted wildlife on a few occassions.

    Chernobyl isn't the radioactive wasteland that people seem to have the idea it is. Mostly this is a fantasy put over by a lot of raving anti-nuclear folks and a whole lot more uninformed but well-meaning people.

    No, the girl on the motorcycle is a hoax and her supposed ideas about how radioactive the ground is are utterly false.

    Please take a look at http://www.chernobyllegacy.com/index.php?cat=1 [chernobyllegacy.com] and other sources before being taken in by the fearmongering.

    There were a total of 46 people that died as a result of Cherynobyl. Somewhere in the low thousands have been treated for thyroid problems and some may in fact die from cancer due to exposure to the materials that were in the immediate area from the reactor fire. Nobody else is expected to die with a cause attributed to the reactor fire.

    People that have taken measuring instruments into the exclusion zone have reported a slightly elevated background radiation and that is all. It is like the difference between living in Italy vs. Norway where Norway gets more cosmic radiation as compared to Italy.

    If Chernobyl was anywhere near as bad as people here seem to think it was, Sweden would be a wasteland as well. It is where a lot of the fallout from the fire settled.

    It's been 21 years since the catastrophe. All the short-lived isotopes are long gone. Heck, most of the isotopes were gone after a few weeks. The radiation levels are currently quite low, up to 7 mSv/year [bbc.co.uk] in the less contaminated areas of the zone. It's only 2-3 times of the natural background in the USA. There are places, where natural radiation is much higher than that. I'm surprised anybody can be surprised the wildlife is soaring. Human (or rather human activity) is the biggest wildlife killer. Radiation in low levels is completely unimportant.
