  1. Results of correlation tests for A) males in the competition context, B) males in the mating context and C) for females in the mating context. Values in the upper corner represent the correlation coefficient r while values in the lower corner are p-values. Significant p-values are printed in bold (p < 0.05). Italic values represent Spearman’s rank correlations while remainder values are based on Pearson’s product-moment correlations
  2. SL standard length, CI condition index, rA achieved chroma, RCA relative colored area, LC Lab-chromaticity
