Jumping Worms Are Taking Over North American Forests – The Atlantic

"They seem so symbolic of a healthy ecosystem,” Dobson says. For their stellar reputation, they can thank none other than Charles Darwin. In addition to developing the theory of evolution, Darwin studied earthworms for 40 years at his home in England.

With characteristic curiosity and rigor, the naturalist conducted all manner of earthworm experiments: He observed their reaction to the sound of the bassoon (none) and to the vibrations of a C note played on the piano (panic). He watched how they pulled leaves into their burrows, and tested their problem-solving skills by offering them small triangles of paper instead (most figured out how to drag them by a corner). Darwin also measured how quickly worms covered up a large paving stone in his garden with their castings. He estimated that they could move at least 10 tons of soil per acre per year.

‘Crazy worms’ have invaded the forests of 15 states, and scientists are worried | Live Science

Some call them crazy worms. Pick one up, and you'll see why, as the creepy-crawly jerks, writhes and springs out of your hand. (It may even leave its tail behind, as a grim souvenir.) And now, scientists are finding the wrigglers have spread to at least 15 states across the U.S.

The worms of the genus Amynthas — also known as snake worms, Asian jumping worms and Alabama jumpers, according to Smithsonian Magazine — are a highly invasive lot that first made their way to North America in the 19th century, stowed away on ships carrying plants and dirt. Since then, they've spread, well, like crazy, and have now been sighted in more than a dozen states, including Minnesota, Wisconsin, Missouri, Illinois, Iowa, Nebraska, Ohio, Texas, Louisiana, Indiana, Kansas, Indiana, Kentucky, Tennessee and Oklahoma, Newsweek.com reported.

They resemble common earthworms, only smaller and brownish in color. However, their reputation is far more sinister. Adult crazy worms reproduce quickly and without mates, laying clutches of eggs the same color as the soil, according to Smithsonian. Once they hatch, the worms swiftly devour the nutrients in the topsoil around them, leaving behind a loose, grainy mess that resembles coffee grounds.

This nutrient-depleted soil erodes quickly, leaving little sustenance for native plants, or competing species of worms and fungi, Brad Herrick, an ecologist at the University of Wisconsin-Madison, told PBS Wisconsin.

Variously known as jumping worms, snake worms, Alabama jumpers, and Jersey wrigglers, common Amynthas species are a super-powered version of the more familiar, squishy languidness of the garden-variety European earthworms (whose genus name, Lumbricus, itself sounds plodding). And their rapid spread into new areas has led to a surge of concern about these worms.

This vigorous lifestyle can quickly lead to full-blown infestations — and decimated topsoil. Perhaps it’s no wonder jumping worms recently have been invading the internet, too.

A Giant Organic Farm Faces Criticism That It’s Harming The Environment : NPR

Hardly a week goes by, it seems, without a big food company making promises to deliver products from green, sustainable farms. Turning those promises into reality, though, can be complicated.

Take Gunsmoke Farms, a vast property that covers 53 square miles just northwest of Pierre, S.D. The food company General Mills, maker of Cheerios, announced in 2018 that it would convert the farm to organic production. The company planned to turn it into an educational hub to teach other farmers "how to implement organic and regenerative agriculture practices."

Now, some of Gunsmoke Farms' neighbors say that the farm is doing more environmental harm than good.
