Multiple mating or group spawning leads to post‐copulatory sexual selection, which
generally favours ejaculates that are more competitive under sperm competition. In four …

Of many determining factors of copulation duration across arthropods, I reviewed copulation
duration variance in mate-guarding worm-like millipedes. The objective wass to calculate …

duration variance in forest millipedes. The objective was to calculate the variance in …

Centrobolus typically has prolonged copulation as a form of syn-copula mate-guarding.
Variations in the copulation duration were calculated and analyzed in four species of the …

In contrast to early predictions, it is now widely accepted that males incur substantive costs
from ejaculate production. Hence, males are predicted to allocate their reproductive …

The good-sperm and sexy-sperm (GS-SS) hypotheses predict that female multiple mating
(polyandry) can fuel sexual selection for heritable male traits that promote success in sperm …

In theoretical and experimental approaches to the study of sperm competition, it is often
assumed that ejaculates always contain enough sperm of good quality and that they are …

The prevalence and evolutionary consequences of cryptic female choice (CFC) remain
highly controversial, not least because the processes underlying its expression are often …

Cryptic male mate choice occurs when males differentially allocate resources to females
during or after copulation. When male resources are limited, males may benefit by …
