Field observations of vegetation patchiness in drylands reveal periodic patterns having characteristic length scales and patch sizes, along with patterns characterized by broad patch size distributions, often reported to obey power-laws. Despite the numerous theoretical and experimental studies that have been devoted to vegetation patchiness this dichotomy of patterns has remained poorly understood. Using a mathematical modeling approach we elucidate the mechanisms that control patch size… CONTINUE READING
