It's a case of what we call species specific dependency.

这就是我们所说的物种的特异性。

" It's highly species specific. I seriously doubt we'll be seeing any real-life human zombies anytime soon."

“这是高度物种特异性。我严重怀疑我们不久后就能看到现实生活中的人类僵尸。”

And as for the testicles, well, reproduction tends to be very species specific – that’s why cross-species hybrids are often less fertile.

至于睾丸， 好吧，繁殖往往具有很强的物种特异性——这就是为什么跨物种杂交后代的生育能力通常较差。

The beauty of these biologically-inspired fences is that they target a specific species without restricting the comings and goings of other plants and animals in the ecosystem — it's all about knowing your target's biological kryptonite.

生物篱笆的美妙之处在于，它们针对特定的物种，而不会限制生态系统中其他动植物的进出——这就是了解目标的生物氪点。
