We describe a simple, scalable, modular, and frugal approach to create model ecosystems as millifluidic networks of interconnected habitats (hosting microbes or plants), which offers (i) quantitative and dynamic control over the exchange of chemicals between habitats, and (ii) independent control over their environment. Oscillatory laminar flows produce regions of vortex mixing around obstacles. When these overlap, rapid mass transport by dispersion occurs, which is quantitatively describable as diffusion, but is directional and tunable in rate over 3 orders of magnitude. This acceleration in the rate of diffusion is equivalent to reducing the distance between the habitats, and therefore, the organisms, down to the length scales characteristic of signaling in soil (<2 mm).

植物和微生物的家园–一种表型分析方法,可定量控制有机体与其各自环境之间的信号传递

我们描述了一种简单,可扩展,模块化且节俭的方法,以将模型生态系统创建为相互连接的栖息地(宿主微生物或植物)的微流网络,从而提供(i)定量和动态控制栖息地之间的化学物质交换,以及(ii)对环境的独立控制。振荡层流在障碍物周围产生涡旋混合区域。当这些部分重叠时,会发生通过分散的快速质量传输,这在定量上可以描述为扩散,但在3个数量级以上的速率上是有方向性和可调性的。扩散速率的这种加速等同于减少栖息地之间的距离,从而减少生物体之间的距离,直至土壤中信号传递的特征长度尺度(<2 mm)。
