Elephants and mice

We all know that elephants aren't really scared of mice. But a new study shows that they're really not crazy about something even smaller: ants. In fact, elephants dislike ants so much that they avoid acacia trees that harbor the tiny, six-legged nectar-suckers.On the savanna, acacia trees growing in regions that get a lot of elephant traffic tend to get eaten. But researchers [noticed:noted] that one species of acacia was not much [bothered:gathered] by elephants. And that the [untouched:noticed] acacia was a favorite ant habitat.So the scientists stripped the ant-covered acacia of their [bodyguard:dubbed] bugs, and sure enough, the elephants chowed down. In addition, when the insects were placed on previously ant-free acacias, the elephants took a pass.But how can teeny, tiny ants repel a big old elephant, which is, after all, about a billion times more massive? The answer is in the trunk. Or rather, not in the trunk. Because, as you can probably relate, elephants really hate to have ants up their noses.The [research:study] is published in the journal Current Biology. And it suggests that adding ants could help preserve wooded areas on the savanna. Because ants will ruin any picnic, even for pachyderms.
