Relationship between viability of sperm in own versus rival seminal fluid.

<p>Closed (open) symbols show the effects of the seminal fluid from males of a pair with relatively high (low) sperm viability on their lower (higher) viability rival.</p

Frequency distribution of sperm viability for the males used in this study.

<p>The data are for sperm mixed with the male's own seminal fluid.</p

An evacuated spermatophore.

<p>The seminal fluid (white) discharges only after all sperm (grey) have left the spermatophore.</p

Data from Almbro & Simmons 2013

Excel file containing original data on the morphology, strength and productivity of beetles fathered by males exposed to ionizing radiation (F1), and of beetles subsequently exposed to sexual selection or enforced monogamy for 2 (F2 and F3) generations

Morphological measurements made from male dung beetles reared under different social conditions

Excel spreadsheet containing body mass, size and testes and soma mass, and their log10 transformed values. Data are provided for males reared under high or low competition environments, and males are identified as major (horned) or minor (hornless) males. Five outlying data points are highlighted

Simmons & Firman 2013

Excel spreadsheet containing data on body weights and male genital measurements from natural populations of house mice, and populations undergoing experimental evolution

Reproductive response of males when competing with either a full sibling (FS) or non-sibling (NS) male rival; (a) males raised in full sibling groups (N = 27,) and (b) males raised in mixed relatedness groups (N = 18). Means±S.E are illustrated.
