dataset

Ejaculate quality traits, body mass, combined testis mass and basal metabolic rate for all species examined, collected from the literature (see References file). D=sperm quality traits were measured in samples from dissected specimens rather than ejaculates; (D)=only some of the traits were measured in dissected specimens; *=Combined testis mass was calculated from testicular dimensions or testis volume following: CTM = 1.166 * L * W * W, where L and W are the mean length and width, respectively, of the two testes; **=BMR was converted either from kcal/d (assuming 1L O2 = 4.839 kcal) or from kJ/d (assuming 1L O2 = 20.083 kJ

Data of the 100 mammalian species

Data on sperm number (in millions), sperm length (um), combined testes mass (g) and male and female body mass (g) of all 100 mammalian species used in this study

Estimates of population density and operational sex ratio

Individual estimates of population density (individuals/m2) and operational sex ratio (proportion of males among all individuals) for each of our 10 focal species. The date indicates the first of three consecutive days of data collection for each estimate

Pitnick. 2010. Resolving mechanisms of competitive fertilization success in D. melanogaster. Science 328: 354-357. Variables: N1 – number of progeny sired by the first male to mate. N2 - number of progeny sired by the second male to mate. SR1 – number of first-male sperm in the SR. SR2 – number of second-male sperm in the SR. Sp1 – number of first-male sperm in both spermathecae combined. Sp2 – number of second-male sperm in both spermathecae combine
