Phenotypic means, between and within male coefficients of variation and variance estimates for testis area and sperm length

Phenotypic means (±SE), along with between and within male coefficients of variation and variance estimates for the male characters (testis area and sperm length) used in the analyses. NA = no value. * Indicates species that could not be used for phylogenetic analysis and ° indicates those species for which between-male data could not be calculated. TA= testis area in mm2; MSL = mean sperm length (mm); BMVAR = between male variance; WMVAR = within male variance; BMCV = between male coefficient of variation and WMCV = within male coefficient of variation
