了解生态群落的时间演替和响应气候变暖的潜在机制对于未来的气候预测至关重要。然而，尽管它在生态学和进化中具有根本的重要性，但人们对海洋领域如何应对气候变暖知之甚少。在这里，我们表明，实验变暖的高草草原生态系统显着改变了土壤古菌的群落结构，减少了它们的分类和系统发育的多样性。与之前对细菌和真菌的观察相反，我们显示了变暖和控制之间土壤古菌群落的趋同演替。虽然随机过程占主导地位的古菌群落，其相对重要性随着时间的推移而下降。此外，变暖引起的古菌群落和土壤化学的变化对生态系统功能产生了重大影响。我们的研究结果意味着，虽然生物多样性丧失对生态系统的不利影响可能会更加严重，但在一个更温暖的世界里，土壤古菌群落结构将更具可预测性。
Understanding the temporal succession of ecological communities and the underlying mechanisms in response to climate warming is critical for future climate projections. However, despite its fundamental importance in ecology and evolution, little is known about how the Archaea domain responds to warming. Here we showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity. In contrast to previous observations in bacteria and fungi, we showed convergent succession of the soil archaeal community between warming and control. Although stochastic processes dominated the archaeal community, their relative importance decreased over time. Furthermore, the warming-induced changes in the archaeal community and soil chemistry had significant impacts on ecosystem functioning. Our results imply that, although the detrimental effects of biodiversity loss on ecosystems could be much severer, the soil archaeal community structure would be more predictable in a warmer world.
