原文标题：Study: Noisy Environment Affects Plants
内容简介：
概述：根据美国科学家最新研究，噪声可能会对周边大面积植物生长产生影响，这种影响视植物种而不同。

But Francis says the effects of the noise on the canyon's plants weren't all bad. A flower pollinated by hummingbirds did better near the compressors. Remember, hummingbirds seem to like the noise - probably, Francis says, because it drives away the scrub jays that would otherwise eat the hummingbirds' eggs and young. Francis just published his research in the British journal called Proceedings of the Royal Society D.
University of California Davis ecologist Gail Patricelli also studies how gas drilling noise affects birds - in her case, the greater sage grouse. She says as far as she knows, Francis's work is the first to show how noise impacts plants.
"You kind of hit yourself on the forehead and think, why didn't I think of that?" I reach Patricelli on her cellphone at a remote field site in Wyoming. She says even there it's not quiet.
"We hear airplanes. We hear roads going, you know, way off in the distance that are too far away to see, and yet you can still hear them because sound travels much, much further than a lot of the other types of disturbance. And so it's just an enormous land area that's impacted by noise and we know remarkably little about what that noise does to the ecosystem."
But it seems likely that for long-lived species like the pi?on pines in New Mexico's Rattlesnake Canyon, the effects of noise may continue to reverberate long after the sound of the compressors has gone silent.
但是弗朗西斯说噪音对峡谷中植物的影响不都是负面的。

靠蜂鸟授粉的花就能在压缩机旁边生长得更好。

记住，蜂鸟似乎挺喜欢噪音的。

弗朗西斯说这可能是因为噪音赶走了会吃蜂鸟的蛋和幼仔的灌丛鸦。

弗朗西斯不久之前将其研究成果发表在英国《皇家学会学报D》杂志上。

加州大学戴维斯分校的生态学家盖尔?帕彻西里也在研究天然气钻探开采的噪音是如何影响鸟类的——她的研究对象是大型艾草鸡。

她说，就她所知，弗朗西斯的研究首次展示了噪音是如何影响植物的。

“你会拍着自个儿的脑门想，我怎么就没想到那点呐？”我通过手机联系到帕彻西里，她在怀俄明州一个偏远的牧场上。

她说就算是在那儿也不清静。

“我们能听到飞机的噪音，路上嘈杂的交通，尽管这些都在肉眼看不到的远方，但你还是能听到这些噪音。

因为相比其他类型的干扰，声音的传播距离要远的多。

所以一大片区域都在受噪音影响，而它对生态系统造成的影响，我们却知之甚少。

”
但对于新墨西哥的响尾蛇峡谷中长寿的物种如矮松来说，噪音的影响很可能在压缩机噪音消失很久后仍然存在。
