在1000条河流和河岸上进行的一项实验发现了全球尺度上碳处理的空间模式和控制。河流生态系统接收并处理了大量陆生有机碳，而这些有机碳的命运在很大程度上取决于微生物的活动。然而，在全球范围内，加工速度的变化和控制的特征却很差。为此，我们利用一个同行研究网络和高度标准化的碳处理分析方法，在1000多个河流和河岸地点进行了全球规模的实地试验。我们发现地球的生物群系有不同的碳处理特征。整个纬度地区的处理速度都很缓慢，而较低纬度地区的处理速度则较快。平均速率和变率都随纬度的变化而下降，这表明温度对两极的限制以及对赤道的其他环境驱动因素（如养分负荷）的更大作用。这些结果和数据通过建立基线来帮助量化环境对全球生态系统功能的影响，为前所未有的“下一代生物监测”奠定了基础。
An experiment in >1000 river and riparian sites found spatial patterns and controls of carbon processing at the global scale. River ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater than 1000 river and riparian sites. We found that Earth’s biomes have distinct carbon processing signatures. Slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes. Both the mean rate and variability decline with latitude, suggesting temperature constraints toward the poles and greater roles for other environmental drivers (e.g., nutrient loading) toward the equator. These results and data set the stage for unprecedented “next-generation biomonitoring” by establishing baselines to help quantify environmental impacts to the functioning of ecosystems at a global scale.
