蜜蜂是如何看见不可见的事物的?

How Bees Can See the Invisible

{音乐}

欢迎收看《It’s Okay To Be Smart》节目我是乔.汗森博士 [欢呼声和音乐]
Welcome to It’s Okay To Be Smart, I’m DOCTOR Joe Hanson [cheering and music].
对于蜜蜂和开花植物来说春天就只有两件事: 采蜜和授粉
For bees and flower blossoms, springtime is all about two things: feeding and fertilizing.
花儿想要把基因传给下一代 蜜蜂做同样的事需要进食
See the flowers want to pass their genes on to the next generation, and the bees need
因此两者可以合作 但是蜜蜂是怎么找到花的呢
to eat so they can do the same. So they use a little teamwork. But how do bees find flowers?
花又是怎么找到蜜蜂的呢 当蜜蜂看到花的时候 它到底看到了什么呢
And how do flowers find bees? What does a bee see when they see one of these?
几百万年以来 植物都靠昆虫和其他传粉者
For millions of years plants have evolved to depend on insects and other pollinators
把基因传给下一代的
to carry their genes on to the next generation.
花就像是用了个大霓虹灯说”停这里”
A flower is like a big neon sign they use to say ‘land here!’
作为传粉的报答,
In return for getting a helping hand in making baby plants, most flowers offer up a tasty
许多花都把花蜜作为传粉报酬
treat in the form of nectar.
就像是一场晚宴 你只要吃就好了
It’s like a dinner date, only you eat afterwards.
生物学家把这种安排称作”互利共生” 花能传粉
Biologists call this kind of arrangement ‘mutualism’. The flower gets to spread its genes, and the
蜜蜂能吃到花蜜 然后携带富含蛋白质的花粉
worker bee gets a sugary drink and packs her knees with golden protein-rich pollen to take
回到有着数以万计饥饿的蜂蜜的蜂房
back to the thousands of hungry mouths back at the hive.
每个人都得到了它们想要的
Everybody gets what they want.
花对我们来说很漂亮,但蜜蜂是用不同的光看见它们的
Flowers sure look pretty to us, but bees see them in a completely different light. Literally.
它们不仅通过数以千计个单独的像素组成的复眼  来看见这个世界
Not only do they see the world through these compound eyes made of thousands of individual
还可以看见紫外线中的一个世界,超出人眼所及
pixels, they see a world bathed in ultraviolet. Way beyond what our eyes can see.
我们看到这个 然而他们看到这个
We see this. And they see THIS.
看,特殊的色素吸收了紫外线,它们在花的中心画出了这个巨大的圆心,
See, special pigments absorb the UV light and they paint this big bullseye in the center
指引蜜蜂飞向美味的花蜜,当然,完成了甜蜜的授粉过程
of the flower, guiding the bee to the tasty nectar and of course, that sweet, sweet pollination.
如今蜜蜂和花之间的关系超越视觉之外
Now the relationship between flowers and bees goes way beyond the visual. Scientists from
布里斯托大学的研究者最近发现了蜜蜂可以感知到花的电场
the University of Bristol recently discovered that bees can sense a flower’s electric field.
就像是你穿着袜子跑过地毯 蜜蜂在飞行的时候
Just like when you run across a carpet in your socks, bees build up a positive charge
会产生正电荷 而花是稍微带着负性的
as they buzz through the air. And flowers are slightly negative.
这帮助花粉从花朵上跳跃到蜜蜂(正负相吸)就像电动尼龙搭扣。
This helps pollen jump from the flower to the bee like electric velcro. It also helps
这也让蜜蜂知道是不是有别的传粉者已经拜访了这朵花并吃完了所有的
the bee figure out if another worker has already visited that flower and slurped up all the
好货
goodness.
目前没有人完全了解蜜蜂是如何感知电荷的,但他们毛茸茸的
Now, nobody knows quite how the bees sense that electric charge, but their fuzzy little
小身体嗡嗡响就像你用气球摩擦你的头发
bodies might be buzzing like your hair when you rub a balloon across it.
现在,进化在蜜蜂和花之间扮演了上百万年的媒人,
Now, evolution’s been playing matchmaker between bees and flowers for millions of years, resulting
产生了自然界最为亲密的关系之一。
in one of nature’s closest relationships.
所以下次你看到一只蜜蜂在温暖的春日下午飞在花园里,
So next time you see a bee buzzing around the garden on a warm spring afternoon, imagine
想象它们看见的世界,并思考大自然还有多少无形的
how their world looks, and think about how much of nature is invisible unless you see
除了你这双眼直接所能看到的之外
it through the right pair of eyes.
