Abstract

Biotin is an essential micronutrient needed but not synthesized by animals. We performed a field experiment where we measured biotin levels and the community composition of nematodes in the rhizosphere of two legumes, the native Lotus corniculatus and an invasive alien, Lupinus polyphyllus. The relative abundance of root-feeding nematodes and the biotin concentration in nematodes were lower in the rhizosphere of the alien. We are the first to show that biotin levels in indigenous nematode populations are associated with the host plant species, and that the difference may affect nematode community.
