The majority of the ambiguity resided in color and contrast variations. Resolution was remarkably great and constant, as witnessed by the pixel by pixel similarity four years apart seen in Fig. This exact same figure also showed that most fairy circles changed really little or not at all among and. When transform comes, it seems to come rather rapidly ircles enlarge and new circles appear in years or much less and normally obtain a tall perimeter within years or much less; dying circles show the color changes of revegetation in years or

The latter assumption is probably acceptable for the relatively uniform location covered by the satellite photographs plus the “sold circle” areas. All of these consist of dune fields and winddeposited sand plains and flats. Irrespective of whether circle life spans are related on much more gravelly soils or alluvial soils covered with a thin veneer of sand, or in distant regions of mibia remains to be tested. The assumption of uniformity in time also remains to become tested, and may not hold up for the reason that it appears most likely that circles are formed and revegetated following summer rains, and they are notoriously variable. For instance, whereas the mean rainfall inside the mib Rand ture Reserve is mm per annum, saw mm by the end in the austral summer in March. Moreover, the uneven distribution of green in Fig. G, H, I and K suggests that even pretty locally, rainfall may very well be really variable. Strictly then, my estimates of life span apply towards the alterations in between and, but nonetheless, the fact that the “sold” fairy circleave a One particular one.orgsimilar estimate over up to years suggests that these estimates are also reasoble over a longer period. The contention by van Rooyen et al. that fairy circles are extra or less permanent attributes with the landscape has now been falsified by my data, specifically by the comparison of satellite photos from with these taken in. Circles clearly seem and disappear, a fact that was checked numerous occasions around the ground. Albrecht et al. recognized the big phases from the fairy circle life cycle, but contrary to their expectations, comparison of satellite photos suggested that fairy circles usually do not commence modest and develop to mature size. Rather, they seem to seem a lot more or much less at their fil size, acquiring the tall perimeter of grass in much less than years. Simply because my satellite pictures were separated by 4 years, and my visit occurred in, my limit of temporal resolution was years. It appears likely that new fairy circles appeared at a related rate in every in the years in between the photos, and they appear without the need of the tall perimeter.
