Researchers get to the bottom of fairy circles

Fairy circles are round gaps in arid grassland that are distributed very uniformly over the landscape and only occur along the Namib Desert in southern Africa and in parts of Australia. Various theories circulate about the actual cause of these unusual spatial patterns, ranging from poisonous Euphorbia plants or rising gases, to ants, termites or plant competition for sparse water resources. Scientists from the University of Göttingen, Australia and Israel have now got to the bottom of their cause with soil investigations and drones.
