Hubs moisture from termites
Description
The reasons for their occurrence are not yet fully understood, but there is a theory, which is supported by most researchers. It suggested that the cause of the mysterious stains are the termite species Psammotermes allocerus. Through such circles Psammotermes allocerus collect water. Insects gnaw plant roots, thereby clearing them from the selected area. After the rains the moisture seeps through the sand and stored at a depth of 25-40 inches, while outside the circle the water is quickly absorbed and evaporated by plants. Analysis of the soil confirmed this opinion in a circle of soil moisture 5 times more than outside. Spots and kept clean from recorded wind-blown seeds and eventually grow.
This phenomenon is found in the media as "circles" in the Namib desert.
