Most research on these self-organizing patterns are in systems where fairy circles persist long-term.

大多数关于这些自组织模式的研究都是在童话圈长期存在的系统中进行的。

Researchers used experimental testing and mathematical modeling to uncover how fairy circles form in salt marshes.

研究人员使用实验测试和数学模型来揭示仙女圈是如何在盐沼中形成的。

To test if these ecological processes were driving patterns, scientists sampled from different areas of fairy circles— the center of rings, on the rings, and the bare, outer edge.

为了测试这些生态过程是否是驱动模式，科学家们从仙女圈的不同区域——环的中心、环上和裸露的外缘——进行了采样。
