Abstract
International audience; Aims : The passage of seeds through the earthworm gut potentially damages seeds, altering seed and seedling performances depending on seed traits. This work was conducted to study to what extent chemical and morphological seed traits determine the seed attractiveness for earthworms. Methods : We tested seed selection via the ingestion and digestion of 23 grassland plant species spanning a range of 14 morphological and chemical traits by two common earthworm species: the anecic Lumbricus terrestris and the endogeic Allolobophora chlorotica. Results : Both earthworm species ingested seeds from all plant species. A. chlorotica digested almos...
