Measures of urinary neopterin levels corrected for creatinine (μmol/mol) from chimpanzees living in captivity (N = 58 samples), Taï (N = 75 samples) and Sonso (N = 45 samples). Individuals: Ncaptivity = 58 (26 males, 32 females), NTaï = 29 (15 males, 14 females), NSonso = 29 (12 males, 17 females). The y-axis is displayed on a log scale. The boxes illustrate the 25th and 75th percentiles, bars indicate medians, and circles indicate outliers
