French worms wriggle as far north as Ireland

No clash seems to be looming as the French worms prefer to eat a different part of the soil as their Irish cousins, according to a report Wednesday in the Royal Society Journal Biology Letters.

But their picky palate may hold another danger — possibly unleashing Earth-warming carbon dioxide left hitherto undisturbed by the native worms.

Scientists studying earthworms on a farm in Dublin last year, discovered “abundant populations” of a species endemic to France's Aquitaine region more than 1,000 kilometers (620 miles) to the south.

Some also live naturally in northern Spain, Sardinia and parts of northern Africa.
