文摘
- •
Protein sources of worms were identified with amino acid 13C fingerprinting.
- •
Anecic earthworm species relied mostly on plant-derived amino acids.
- •
Endogeic earthworms relied equally on bacterial and plant-derived amino acids.
- •
Enchytraeid worms resemble endogeic earthworms in terms of EAA sources.
- •
EAA targets were neither tied to crop type nor the size of individual earthworms.
