Multivariate relationship between male reproductive success and the seminal fluid composition. An ordination of the 15 C. maculatus populations studied here along the first pair of canonical variables, showing a significant covariation between the relative abundance of 56 SFPs (along the abscissa) and the reproductive phenotypic responses to seminal fluid (along the ordinate) (R c = 0.97, Bartlett’s test: χ2 36 = 56.7, P = 0.015). The second pair of canonical variables were marginally non-significant (R c = 0.93, Bartlett’s test: χ2 25 = 35.4, P = 0.081). A sizeable and significant proportion of total variance in reproductive phenotypes across populations was thus accounted for by variance in SFP abundance (Stewart-Love Canonical Redundancy Index: Rd = 0.713, bootstrapped 95 % CI: 0.61 − 0.80)
