Antagonistic potential of soil streptomycetes. The level of antagonism was determined as the ratio between the inhibition zone against S. sudanensis and colony size of soil streptomycetes. Data are presented in dependency of annual precipitation (a), ecoregion (b), soil type (c), Mycetoma (d) Streptomyces abundance (e), and phenotypic diversity of Streptomyces isolates (f). Abundance corresponds to the mean value of colony forming units (× 105 / g soil) on humic acid and ISP2 agar; Annual precipitation to precipitation levels 0–100 mm (very low), 101–400 mm (low), 401–600 mm (moderate) and 601–1000 mm (high); Ecoregion to East Sudanian savanna (EaSuSa), Sahelian Acacia savanna (SaAcSa) and South Saharan steppe and woodlands (SSaStWo), Mycetoma for the geographical origin of bacteria, from mycetoma belt, with confirmed, and without confirmed actinomycetoma. The Pearson correlation coefficients (R and p-value) are provided as measures of the strength of linear association between two variables
