文摘
- •
Abundance of earthworms and cocoons decreased significantly along a copper gradient.
- •
Internal concentration of copper reached 100–160 mg kg−1 in the most copper polluted soil.
- •
Hatchability of field collected cocoons was not impaired by copper in any species.
- •
Increased tolerance may be acquired through natural selection and genetic adaptation.
