Abstract

Microbes inhabit virtually all river ecosystems, influencing energy flow and playing a key role in global sustainability and climate change. Yet, there is uncertainty about how various taxonomic groups respond to large-scale factors in river networks. We analysed microbial community richness and composition across six European Atlantic catchments using environmental DNA sequencing. Our findings reveal different drivers for diversity and composition: land use is pivotal for eukaryotes, while climate and geology are crucial for prokaryotes. A strong regional influence shapes these communities, with warmer, drier regions (Portugal and France) differing from cooler, wetter ones (Northern Spain, Ireland and the United Kingdom). These patterns suggest potential indicators for global change, such as taxa resistant to temperature increases and water scarcity, or those sensitive to land use changes.

大西洋流域河流微生物群落的生物地理分布。

微生物几乎栖息在所有河流生态系统中，影响着能量流动，在全球可持续性和气候变化中发挥着关键作用。然而，不同的分类类群如何响应河网中的大尺度因子，还存在不确定性。我们利用环境DNA测序分析了六个欧洲大西洋流域的微生物群落丰富度和组成。我们的发现揭示了多样性和组成的不同驱动因素：土地利用对真核生物至关重要，而气候和地质对原核生物至关重要。强烈的区域影响塑造了这些社区，温暖、干燥的地区（葡萄牙和法国）与凉爽、潮湿的地区（西班牙北部、爱尔兰和英国）不同。这些模式提供了全球变化的潜在指标，例如对温度升高和水资源短缺具有抵抗力的分类群，或对土地利用变化敏感的分类群。

期刊介绍： The journal is identical in scope to Environmental Microbiology, shares the same editorial team and submission site, and will apply the same high level acceptance criteria. The two journals will be mutually supportive and evolve side-by-side. Environmental Microbiology Reports provides a high profile vehicle for publication of the most innovative, original and rigorous research in the field. The scope of the Journal encompasses the diversity of current research on microbial processes in the environment, microbial communities, interactions and evolution and includes, but is not limited to, the following: the structure, activities and communal behaviour of microbial communities microbial community genetics and evolutionary processes microbial symbioses, microbial interactions and interactions with plants, animals and abiotic factors microbes in the tree of life, microbial diversification and evolution population biology and clonal structure microbial metabolic and structural diversity microbial physiology, growth and survival microbes and surfaces, adhesion and biofouling responses to environmental signals and stress factors modelling and theory development pollution microbiology extremophiles and life in extreme and unusual little-explored habitats element cycles and biogeochemical processes, primary and secondary production microbes in a changing world, microbially-influenced global changes evolution and diversity of archaeal and bacterial viruses new technological developments in microbial ecology and evolution, in particular for the study of activities of microbial communities, non-culturable microorganisms and emerging pathogens.
