Reproductive mode and the genetic benefits of polyandry
Article Abstract:
Research describing reproduction from the female point of view with reference to the possible benefits of polyandry is presented. Studies show that polyandry is less important for egg laying females than viviparous females.

Spontaneous abortion depresses female sexual receptivity in a viviparous arthropod
Article Abstract:
Research undertaken among female Cordylochernes scorpioides pseudoscorpions indicates that the negative effect of abortion on female sexual receptivity could impose physiological restrictions on the ability of viviparous females to use polyandry as a facultative mating technique for balancing out the impact of a poor first mate.

Outbred embryos rescue inbred half-siblings in mixed-paternity broods of live-bearing females
Article Abstract:
Polyandry in viviparous pseudoscorpions reduces inbreeding cost not through paternity-biasing mechanisms favoring outbred of offspring, but because outbred embryos exert a rescuing effect on inbred half-siblings in mixed-paternity broods. The benefits of polyandry may thus be more complex for live-bearing females than for females that lay eggs.
