From: Artificial light at night reduces earthworm activity but increases growth of invasive ragweed
Earthworm surface activity assessed with the toothpick index (A) and the surface casting activity (B) throughout all 12 samplings, considering effects of light pollution (D…dark, L…light) and sowing depth (0…surface sown, 5…sown in 5 cm depth). N = 6. Each box represents the 1st and 3rd quartiles, the median as the horizontal line and the whiskers as minimum and maximum values
