工程生态系统跨越多个体积尺度，从纳米尺度到数千立方米。即使是最大的工业系统也会在中试规模的设施中进行测试。但规模会影响结果吗？在这里，我们比较不同尺寸的实验室厌氧发酵罐，看看群落的体积是否以及如何影响群落合并（组合多个群落）对群落组成和功能的结果。我们的结果表明规模对沼气生产有影响。此外，我们看到群落均匀度和体积之间的联系，规模较小的群落具有更高的均匀度。尽管存在这些差异，但群落合并的总体模式在所有规模上都非常相似，合并导致的沼气产量水平与表现最好的组成群落的水平相当。沼气的增加随着体积的增加而增加，表明存在一个体积，在大体积的情况下，生产率保持稳定。我们的研究结果让研究大型生态系统和运行中试规模设施的产业的生态学家感到安心，因为它们支持了该领域中试规模研究的有效性。
Engineered ecosystems span multiple volume scales, from a nano-scale to thousands of cubic metres. Even the largest industrial systems are tested in pilot scale facilities. But does scale affect outcomes? Here we look at comparing different size laboratory anaerobic fermentors to see if and how the volume of the community affects the outcome of community coalescence (combining multiple communities) on community composition and function. Our results show that there is an effect of scale on biogas production. Furthermore, we see a link between community evenness and volume, with smaller scale communities having higher evenness. Despite those differences, the overall patterns of community coalescence are very similar at all scales, with coalescence leading to levels of biogas production comparable with that of the best-performing component community. The increase in biogas with increasing volume plateaus, suggesting there is a volume where productivity stays stable over large volumes. Our findings are reassuring for ecologists studying large ecosystems and industries operating pilot scale facilities, as they support the validity of pilot scale studies in this field.
