英文摘要	Changes in the soil nematode community induced by global warming may have a considerable inlfuence on agro-ecosystem functioning. However, the impacts of predicted warming on nematode community in farmland (e.g., winter wheat ifeld) have not been well documented. Therefore, a ifeld experiment with free air temperature increase (FATI) was conducted to investigate the responses of the soil nematode community to nighttime warming in a winter wheat ifeld of Yangtze Delta Plain, China, during 2007 to 2009. Nighttime warming (NW) by 1.8℃ at 5-cm soil depth had no signiifcant impact on the total nematode abundance compared to un-warmed control (CK). However, NW signiifcantly affected the nematode community structure. Warming favored the bacterivores and fungivores, such as Acrobeles, Monhystera, Rhabditis, and Rhabdontolaimus in bacterivores, and Filenchus in fungivores, while the plant-parasites were hindered, such as Helicotylenchus and Psilenchus. Interestingly, the carnivores/omnivores remained almost unchanged. Hence, the abundances of bacterivores and fungivores were signiifcantly higher under NW than those under CK. Similarly, the abundances of plant-parasites were signiifcantly lower under NW than under CK. Furthermore, Wasilewska index of the nematode community was signiifcantly higher under NW than those under CK, indicating beneifcial effect to the plant in the soil. Our results suggest that nighttime warming may improve soil fertility and decrease soil-borne diseases in winter wheat ifeld through affecting the soil nematode community. It is also indicated that nighttime warming may promote the sustainability of the nematode community by altering genera-speciifc habitat suitability for soil biota.
