The effects of the invasive plants on soil nematodes vary with the duration of elevated CO₂ treatment.

ABSTRACT: Exotic plant invasions and increased atmospheric carbon dioxide (CO₂) concentration have been determined to independently affect soil nematodes, a key component of soil biota. However, little is known about the long-term effects of these two global change factors and their interactive effects. Over three consecutive years, we cultivated invasive alien plant Xanthium strumarium and its two phylogenetically related natives under both ambient (aCO₂) and elevated (eCO₂) atmospheric CO₂ concentrations, and determined the effects of the invader and natives on soil nematodes under different CO₂ concentrations and the relevant mechanism. The abundance of total soil nematodes and that of the dominant trophic group (herbivores) were signi
