| 英文摘要 | It is well established that climate warming has become a growing issue globally, posing a threat to native ecosystems. Alpine ecosystems, such as meadows of the Qinghai-Tibet Plateau, are expected to be particularly sensitive to warming given current temperature constraints. While many studies have explored the effects of warming on aboveground ecosystems and edaphic properties, few studies have assessed the effects on soil biota. We assessed edaphic, plant, microbial and nematode responses to warming ina long-term (8 year) multilevel warming experiment and applied piecewise structural equation modelling to reveal how warming affected nematode communities directly and indirectly via biotic and abiotic factors. We found that (1) warming had a significant effect on nematode community composition, which was mainly due to direct warming effects on herbivores and omnivore-predatory nematode composition; (2) warming affected nematode richness mainly through effects on bacterial richness, with a strong negative relationship between bacterial richness and bacterivore richness as well as bacterivore richness and omnivore-predatory richness; and, (3) the predominantly direct effect of warming on nematode biomass was mainly due to significant responses of omnivore-predatory biomass. Our study provides insight into the effects of long-term warming on nematode communities and highlights the contrasting responses of composition, diversity and biomass to warming. It contributes to forecasting warming effects on the structure of soil food webs and ecosystem functioning on the Qinghai-Tibet plateau in the future. |
