A worm is a worm is a worm, right? Except that there are more than 7,000 species of worms, and the longer you look, the more complex their world becomes. Earthworms compete. Earthworms invade. Earthworms… jump?

Imagine walking through a forest, with leaves crunching beneath your feet. Underneath those crunchy leaves is a complex ecological realm. “Soil is teeming with life,” says U.S. Forest Service research ecologist Mac Callaham. “Most people don’t think about it because they don’t see the soil fauna.” Soil fauna includes centipedes, millipedes, springtails, nematodes, insect larvae, and earthworms. “Springtails are very small arthropods,” says SRS ecologist Melanie Taylor. “Earthworms are the giants of soil fauna.” Taylor, Callaham, and lead author Meixiang Gao recently published a study on non-native earthworms and the food web. The study was published in the journal Soil Biology and Biochemistry.

The invasive Asian jumping worm (Amynthas agrestis) has many common names: Alabama jumpers, Jersey wrigglers, wood eel, crazy worms, snake worms, and crazy snake worms. “Invasive Asian jumping worms got their name because of the way they thrash around,” said Mac Callaham, a Forest Service researcher who specializes in soils. “They can flip themselves a foot off the ground.”
Like other earthworms, Asian jumping worms eat tiny pieces of fallen leaves. But there’s a problem. Those fallen leaves make up the top layer of forest soil. The litter layer, as it’s called, is home to a vast number of tiny animals. Many plants can’t grow or spread without the layer of leaf litter. “Soil is the foundation of life – and Asian jumping worms change it,” says Callaham. “In fact, earthworms can have such huge impacts that they’re able to actually reengineer the ecosystems around them.”

What could be more 2020 than an ongoing invasion of jumping worms? These earthworms are wriggling their way across the United States, voraciously devouring protective forest leaf litter and leaving behind bare, denuded soil. They displace other earthworms, centipedes, salamanders and ground-nesting birds, and disrupt forest food chains. They can invade more than five hectares in a single year, changing soil chemistry and microbial communities as they go, new research shows. And they don’t even need mates to reproduce...
