Alien Invasion: Non-native earthworm species threaten US ecosystem, warn Stanford scientists
Researchers at Stanford University have identified up to 70 non-native earthworm species in the US that could have devastating ecological consequences. These invasive species consume more aboveground leaf litter than native worms, potentially destroying plants and impacting insects and amphibians.
The ballooning population of non-native "alien" earthworm species in the United States could pose significant ecological consequences, scientists at Stanford University have warned, DailyMail reported. As many as 70 different types of earthworms native to Asia, Europe and South America have been identified as potential threats, it said.
