May 18th is the 37th anniversary of the massive explosion of Mount Saint Helens.

点击显示原文

隐藏原文=

But within days of the volcano erupting, the local ecosystem started to bounce back.

点击显示原文

隐藏原文=

Thanks to some unassuming little animals that spend lots of time underground.

隐藏原文=

"The pocket gophers were the ecological heroes of Mount Saint Helens."

Emory University paleontologist and geologist Anthony J.Martin.

"You normally don't hear those words put together, pocket gopher and hero.

点击显示原文

隐藏原文=

But they were...these small burrowing mammals were able to survive this massive, devastating volcanic eruption."

点击显示原文

隐藏原文=

Just as numerous animals that live underground have survived catastrophes and predators for hundreds of millions of years.

点击显示原文

隐藏原文=

As Martin discusses in his new book The Evolution Underground: Burrows, Bunkers, and the Marvelous Subterranean World Beneath Our Feet.

点击显示原文

隐藏原文=

"The reports I was reading about this, about how these researchers in helicopters are flying over the devastated landscape-just a few days later there were the burrow mounds.

点击显示原文

隐藏原文=

Pop pop pop.

点击显示原文

隐藏原文=

Thinking about these gophers that were below the ground.

点击显示原文

隐藏原文=

And they survived that....

点击显示原文

So other small mammals and other vertebrates, such as amphibians and reptiles that lived there, they were either in their own burrows or they were in pocket gopher burrows or other small mammal burrows in the area.

点击显示原文

隐藏原文=

"The burrowing also brought up seeds.

点击显示原文

隐藏原文=

The seeds are already buried, so that caused plants to start sprouting in the area, where it wasn't so much wind-blown seeds...

点击显示原文

隐藏原文=

then of course once other animals started coming back into the area, like elk, and they started dropping seeds through their feces and otherwise affecting the surface ecology, that then worked together to bring those ecosystems back to life.

点击显示原文

隐藏原文=

But the gophers were key in this.

点击显示原文

隐藏原文=

They really were essential for these ecosystems to be able to bounce back."

点击显示原文

隐藏原文=

You can hear an extended interview with Martin about his book in a Science Talk podcast posted on our website.

点击显示原文

隐藏原文=

And there's a children's book just about the gophers and Mount Saint Helens called Gopher to the Rescue by Terry Jennings.

点击显示原文

隐藏原文=

Finally, for general information about gophers and their effect on landscapes, check out the nature documentary Caddyshack.
