Provides descriptive information regarding measurements of male reproductive traits (sample size, mean, standard error, minimum and maximum values). Table S2. Provides Pearson correlation coefficients calculated between measures of morphological traits used in main analyses. Table S3. Shows results of generalized linear mixed model to investigate morphological traits influencing male reproductive success, using results of principal components analysis for baculum size measurements.

Table S5. Shows results of generalized linear mixed models to investigate morphological traits influencing male reproductive success, including analysis of individual morphological traits, and combined models for significant traits. Table S6. Shows results of linear mixed models to investigate morphological traits influencing male paternity success, including analysis of individual morphological traits, and combined models for significant traits.
