温度和生物可利用能控制着地球上生命的分布，并由于生物能量需求对温度的依赖而相互作用。在这里，我们分析了温度-能量相互作用如何在瓜伊马斯盆地的两个热液活动区形成沉积物微生物群落结构。一个区域的站点经历了热源产生的电子给体的平流输入，从更深的层渗入，而另一个区域的站点是扩散主导和电子给体枯竭的。在这两个地点，古生菌在&45 °C的温度下占主导地位，细菌在<；10 °C的温度下占主导地位。然而，在门的水平和以下，有明显的区别。热渗漏区具有较高比例的典型热液喷口和温泉类群。相比之下，没有渗漏的高温场地主要是分布在寒冷海底沉积物中的新类群。我们的结果表明，在热液沉积物中，温度决定了域级别的优势，而温度-能量的相互作用则在门级别和更低的级别构建了微生物群落。Lagostina等人。结果表明，加利福尼亚州海湾瓜伊马斯盆地沉积物中细菌和古细菌的相对丰度受温度控制，而能量通量解释了门水平及以下的微生物群落结构。热扩散为主和能量耗竭的沉积物以冷海底沉积物中有近亲的类群为主，而流体渗流提供高能量的热沉积物则以也存在于热液喷口和温泉中的类群为主。
Temperature and bioavailable energy control the distribution of life on Earth, and interact with each other due to the dependency of biological energy requirements on temperature. Here we analyze how temperature-energy interactions structure sediment microbial communities in two hydrothermally active areas of Guaymas Basin. Sites from one area experience advective input of thermogenically produced electron donors by seepage from deeper layers, whereas sites from the other area are diffusion-dominated and electron donor-depleted. In both locations, Archaea dominate at temperatures >45 °C and Bacteria at temperatures <10 °C. Yet, at the phylum level and below, there are clear differences. Hot seep sites have high proportions of typical hydrothermal vent and hot spring taxa. By contrast, high-temperature sites without seepage harbor mainly novel taxa belonging to phyla that are widespread in cold subseafloor sediment. Our results suggest that in hydrothermal sediments temperature determines domain-level dominance, whereas temperature-energy interactions structure microbial communities at the phylum-level and below. Lagostina et al. show that relative abundances of Bacteria and Archaea in sediments of Guaymas Basin, Gulf of California, are controlled by temperature, while energy flux explains microbial community structure at the phylum-level and below. Hot diffusion-dominated and energy-depleted sediments are dominated by taxa with relatives in cold subseafloor sediments, while hot sediments with high energy supply from fluid seepage are dominated by taxa also found at hydrothermal vents and in hot springs.
