Journal ArticleDOI
Sperm competition, male prudence and sperm-limited females
TL;DR: This work focuses on studies showing that males assess mating status and relative fecundity of females, and reveals that modulation of ejaculate investment by males can sometimes result in sperm limitation for females.
Journal ArticleDOI
Sperm competition in fishes: the evolution of testis size and ejaculate characteristics.
TL;DR: It is found that both the gonadosomatic index and sperm numbers increase with intensity of sperm competition across species but that sperm length decreases, which does not fit predictions of current sperm competition theory.
Journal ArticleDOI
Spermatozoal traits and sperm competition in Atlantic salmon: relative sperm velocity is the primary determinant of fertilization success.
Matthew J. G. Gage,Christopher P. Macfarlane,Sarah E. Yeates,Richard G. Ward,Jeremy B. Searle,Geoffrey A. Parker +5 more
TL;DR: Natural variation in spermatozoal traits among wild Atlantic salmon, a species naturally adapted to sperm competition, is used to examine how the relative influences of sperm number, velocity, longevity, and total length determine sperm competition success.
Journal ArticleDOI
Associations between Body Size, Mating Pattern, Testis Size and Sperm Lengths across Butterflies
TL;DR: The results suggest that sperm competition in butterflies selects for increased investment in spermatogenesis, and specifically longer fertilizing sperm, which are not selected to be minimally sized to maximize numbers for a purely raffle-based sperm competition mode.
Journal ArticleDOI
Sperm competition games: a prospective analysis of risk assessment
TL;DR: The logic of assessment of sperm Competition risk by individual males where the mechanism of sperm competition follows a ‘loaded raffle’ is developed and biological evidence for the predictions is summarized and discussed.
