A loss of 10% will not be noticible by general observation but would if scientifically measured. Given that, there still may be a difference between the Russian and US power lines - manufacture, configuration, spacing, etc.. Also, what might be causing the decrease is interesting, since the fix seems to be to cool the hives when directly under the power lines. Dirt and trees would seem to have little shielding effect on the electrical characteristics but would tend to cool the hives. But that does not explain the 50 meter move, unless it is also to a cooler place. Have there been any other studies? I would think so. Which brings up another question. Is there a source on the web for scientific abstracts and papers dealing with bees? A lot of our questions and arguments would be settled by having such a source. Or then, maybe not.
