In new Spanish research, they measured the common conditions found in the environment of fairy circles found in some places in the world, and exactly where they are located on our planet. There have been many theories regarding the origin of fairy circles, some of which have been refuted, others not proven, so we can say that we still have no explanation for their formation. Despite many previous theories, there is still very little information about how many places this phenomenon actually occurs. the With people A study published in the journal University of Alicante to explain.
The researchers measured the locations of fairy circles in two well-known locations – Namibia and Western Australia – and then looked for similar locations around the world. The researchers examined climatic, soil and environmental conditions, groundwater levels, and surface albedo, including soil microbes, and analyzed the impact on the living world in each region and the functioning of ecosystems. Then, a large number of satellite images were analyzed with the help of artificial intelligence, and based on this, the conditions for the formation of fairy circles exist in a total of 15 countries, in 263 locations, and patterns similar to fairy circles were found. They are found in these regions: Sahel, Western Sahara, Madagascar, Southeast Asia, Central Australia and the Horn of Africa (Somalia and Ethiopia region). This means, according to the Spanish researchers, that vegetation with a similar structure may be more common in the world.
It turns out that fairy circles are typical for those places where annual precipitation is less than 200 mm, where the soil is low in nitrogen. However, for example, the presence of ants or termites (one idea linked the imaginary circles to these) does not explain all these places in the world, only in the Namibian site could termites be linked to the circles.
Where fairy circles have appeared, vegetation growth has been more stable in these areas than in places without fairy circles, but it is not clear whether this indicates, for example, that the ecosystem in these places is also more protected against climate change. the climate. However, the database compiled by the researchers is a good starting point for future research that can answer this question as well.
